Abstract
The aim of this study was to verify the presence and identify the species of haemosporidian parasites in eared doves (Zenaida auriculata) in Brazil. Two hundred and eleven male and female eared doves were trap-captured in four different regions of Londrina city, in southern Brazil. Whole blood was collected in EDTA tubes through heart puncture after euthanasia in a CO2 chamber. A nested PCR targeting the mitochondrial cytochrome b gene (cyt b) of Haemoproteus spp./Plasmodium spp. was performed, followed by an enzymatic digestion to identify the genus. Phylogenetic trees were constructed to determine the closely related species. Out of 211 eared doves, 209 (99.05%) were positive for Haemoproteus spp. and/or Plasmodium spp. RFLP analysis showed that 72.72% (152/209) of eared doves were positive only for Haemoproteus spp., 6.22% (13/209) were positive only for Plasmodium spp., and 21.05% (44/209) of eared doves had mixed infections. Genetic analysis found four samples that were homologous with Haemoproteus multipigmentatus and one that was homologous with Plasmodium sp. This is the first molecular study of hemoparasites from eared doves in Brazil, and it is also the first description of H. multipigmentatus and Plasmodium spp. infection in eared doves in Brazil.

Abstract
Opossums are marsupials from the New World of the genus Didelphis and known as synanthropic animals due to their proximity with human beings. To date, 'Candidatus Mycoplasma haemodidelphis' has been solely found infecting the North American opossum (Didelphis virginiana). Accordingly, the aim of this study was to screen eight white-eared opossums (Didelphis albiventris) from a public park in Maringa city, Paraná State, southern Brazil, for hemoplasma infection. Blood samples were taken from caudal venipuncture, and DNA was extracted and further screened by a pan-hemoplasma PCR assay. Seven out of eight (87.50%; CI 95%: 47.35-99.68%) white-eared opossums were positive for Mycoplasma spp. Sequencing of the 16S rRNA fragment showed 98,97% identity with 'Ca. M. haemodidelphis' detected in the USA. Three out of eight (37.50%; CI 95%: 8.52-75.51%) white-eared opossums were infested by Amblyomma dubitatum ticks. This is the first report on detection of a potentially novel hemotropic Mycoplasma sp. infecting opossums from South America.

Abstract
Hemotropic mycoplasmas (hemoplasmas) are bacteria distributed worldwide and affect domestic and wildlife animals and human beings. Hemoplasmas have been described infecting hematophagous and non-hematophagous bats; however, transmission risk and zoonotic potential in vampire bats remain to be fully established. This study aimed to evaluate the presence of hemotropic mycoplasma species in free-ranging bats from this area using a universal PCR protocol for hemoplasmas. Accordingly, ten blood samples were collected from six male common vampire bats (Desmodus rotundus), two male hairy-legged vampire bats (Diphylla ecaudata), and two female non-hematophagous Pallas's mastiff bats (Molossus sp.) from the Curitiba's region, Paraná State, Southern Brazil. A total of eight (8/10) blood samples were positive byconventional PCR; five (5/6) Desmodus rotundus, two (2/2) Diphylla ecaudata, and one (1/2) Molossus sp. bats. The analyses of the partial sequence of the 16S rDNA gene suggest that the hemoplasma detected in Desmodus rotundus in South Brazil has a high identity compared to the hemoplasma circulating in vampire bats from Central and South America.

Abstract
Tick-borne diseases (TBD) constitute an important group of illness affecting animals and humans worldwide. In Brazil, carthorses are frequently exposed to ticks and tick-borne pathogens, leading to impairment of horse performance and imposing restrictions by the international veterinary authorities for the importation of horses. Accordingly, this study has aimed to i) determine the prevalence of the TBD agents Theileria equi, Babesia caballi, Ehrlichia spp., and hemotropic mycoplasmas in carthorses, ii) identify the tick species parasitizing the animals, and iii) determine factors associated with exposure/infection in Foz do Iguaçu City, Parana state, southern Brazil. A total of 103 carthorses were screened for anti-T. equi and anti-Ehrlichia spp. antibodies by indirect fluorescent antibody assays (IFA). Samples were also tested by PCR assays targeting the 18S rRNA gene of T. equi and B. caballi, and 16S rRNA gene of hemoplasmas. Additionally, PCR assays targeting the 16S rRNA, disulfide bond formation protein (dsb) and tandem repeat proteins 36 (trp36) genes of Ehrlichia spp. were also performed. Antibodies to T. equi and Ehrlichia spp. were detected in 43/103 (41.75%; 95% CI: 32.10-51.88%) and 5/103 (4.85%; 95% CI: 1.59-10.97%) horses by IFA, respectively. DNA of T. equi and B. caballi were found in 25/103 (24.27%; 95% CI: 16.36-33.71%) and 10/103 (9.71%; 95% CI: 4.75-17.13%) carthorses, respectively, and all tested negative for Ehrlichia spp. and hemoplasmas. All sequences showed ≥99% identity with multiple T. equi and B. caballi 18S rRNA gene sequences deposited in GenBank. Overall, 191 Dermacentor nitens ticks were collected from 25/103 (24.27%) animals. Carthorses older than 5 years were more likely to be positive for T. equi (p < 0.05). In conclusion, equine piroplasmosis agents are highly prevalent in carthorses from Foz do Iguaçu City. The low prevalence of Ehrlichia spp. found may be due to the absence of Amblyomma ticks infesting animals, which should be further investigated.

Abstract
Cryptosporidium is a protozoan parasite with a wide range of hosts, including humans. However, only a few Cryptosporidium species have been described in birds (C. meleagridis, C. baileyi, C. galli and C. avium). The aim of this study was to investigate the occurrence of Cryptosporidium spp. in feces of eared doves (Zenaida auriculata), followed by molecular characterization of the parasite. A total of 196 animals of both sexes were trap-captured; the animals were culled and the intestinal contents were collected for DNA extraction. After extraction, a nested-PCR (nPCR), which amplifies a fragment of the 18S rRNA gene of Cryptosporidium spp., was performed. The amplicons obtained were purified and sequenced. PCR analysis revealed that 30 animals (15.3%) were positive for Cryptosporidium spp. There was no significant sex-dependent enrichment of Cryptosporidium occurrence (p > 0.05). Only 15 out of the 30 positive samples were successfully sequenced and their species determined, of which, 13 (86.7%) and 2 (13.3%) were C. meleagridis and C. galli, respectively. Herein, we present for the first time a molecular characterization of Cryptosporidium from feces of eared doves (Z. auriculata) and propose that these birds are a potential source of C. meleagridis infection in humans.

Abstract
Anaplasma marginale and piroplasm species are widespread among Brazilian cattle herds. Both of these tick-borne pathogens hamper livestock production and cause a significant economic impact. Although buffaloes have demonstrated a high level of adaptability, data on tick-borne pathogens are scarcely reported in Brazil. Thus, the aim of this study was to screen water buffaloes from the state of Maranhão for piroplasm and A. marginale occurrence using PCR assays. All samples were negative for A. marginale. One of the 287 (0.35%) water buffaloes tested was positive for Theileria sp. Sequencing of the 18S rDNA fragment (356 bp) showed that the Theileria sp. identified was closely related to the T. buffeli /orientalis group. Future studies on the clinical signs of infection and the main vector in this country are needed.

Abstract
Anaplasma marginale, the causative agent of bovine anaplasmosis, is a tick-borne bacterium that causes significant economic losses for cattle industries and is increasingly being detected in other animal species. Rhipicephalus microplus is the main vector of this bacterium and may be found parasitizing small ruminants. In northeastern Brazil, multispecies grazing is a common family subsistence practice on smallholder farms possibly facilitating interspecies transmission of pathogens. Considering that A. marginale infection has been previously molecularly described in sheep, this study has aimed to estimate the prevalence of A. marginale and factors associated with the infection in goats from northeastern Brazil. A total of 403 goat blood samples were included in the study. An epidemiological questionnaire was applied to each farm owner addressing age, gender, presence of ticks and multispecies grazing. All samples were screened for A. marginale- and A. ovis-infection using primers targeting the Anaplasma spp. msp4 gene. The identity of A. marginale in the blood was confirmed by PCR amplification of msp5 followed by sequencing. Anaplasma spp. were differentiated by sequencing of the repeat region of the msp1α gene. For the statistical analysis the Chi-square or the Fisher’s exact test was used to verify association of the individual factors (age, gender, presence of ticks, and multispecies grazing) with Anaplasma spp. infection. We report the first molecular detection of A. marginale in goats from northeastern Brazil, based on msp1α, msp4 and msp5 gene sequencing analysis. Sequencing of the detected A. marginale msp1α gene revealed the F repeat. Amblyomma parvum and R. microplus were found feeding on animals.

Abstract
The aim of this study was to investigate the occurrence of Cryptosporidium in cattle and sheep from the North Pioneer mesoregion of the state of Paraná. For this, 317 stool samples were collected from cattle and sheep on 16 properties in six municipalities in the North Pioneer mesoregion of Paraná. For detection of Cryptosporidium species, molecular analysis was performed using nested-PCR techniques targeting the 18S rRNA gene. Of the 37 beef cows and 115 calves analyzed, four (10.8%) and 14 (12.2%), respectively, were positive for Cryptosporidium. Of the 12 cows and 52 calves, one (8.3%) and 14 (26.9%), respectively, were positive for Cryptosporidium; and of the 42 ewes and 59 lambs, six (14.3%) and 12 (20.3%), respectively were positive for Cryptosporidium. Cattle (15.3%) and sheep (17.8%) were both susceptible to infection. All the properties of the municipalities of Assaí, Ibaiti and, Leópolis presented infected animals. The study showed that Cryptosporidium occurs in most municipalities assessed, that dairy calves had a higher risk (Odds Ratio=2,66, p-value=0,018) for infection than beef calves, and that sheep are just as susceptible to infection as are cattle, and that further Cryptosporidium studies are developed.

Abstract
Neospora caninum is an obligate intracellular protozoan parasite that infects domestic and wild animals. Canids are considered to be definitive hosts since they may shed oocysts into the environment through their feces. The disease is recognized as one of the major causes of bovine abortion worldwide, leading to important economic losses in the dairy and beef cattle industries. Previous studies have reported N. caninum infection in different species of birds; infection in birds has been associated with increased seroprevalence and reproductive problems in dairy cattle. Although the role of birds in the epidemiological cycle of neosporosis is unknown, birds are exposed to infection because they feed on the ground and could thus contribute to parasite dissemination. This review is focused on the current state of knowledge of neosporosis in birds.

Abstract
Abstract Bovine coccidiosis is a disease of major importance in cattle herds across the world. The disorder mainly affects young calves, and E. bovis and E. zuernii are considered the most pathogenic species of the genus, however, E. alabamensis have been described in grazing calves. In this study, the prevalence of Eimeria spp. was evaluated in calves on dairy farms in the northern region of the state of Paraná, Brazil. Four hundred calves on 44 dairy farms were tested for the presence of coccidian oocysts. The positives were re-examined and the oocysts were morphometrically analyzed for species identification. All the farms were contaminated and 205 animals (51.25%) presented Eimeria spp. oocysts. Among these, 146 animals (71.22%) were co-infected by two or more species of coccidia. Ten species of Eimeria were identified: E. bovis (in 30.25% of the positive samples), E. alabamensis (26.75%), E. zuernii (22.00%), E. ellipsoidalis (18.50%), E. auburnensis (13.75%), E. canadensis (8.00%), E. cylindrica (7.25%), E. subspherica (5.00%), E. bukidnonensis (3.00%) and E. brasiliensis (0.75%). This study demonstrates the high prevalence of Eimeria spp. in the northern region of Paraná, Brazil, and detection for the first time in our region the pathogenic species E. alabamensis.

Abstract
Neosporosis is an infectious disease caused by Neospora caninum, a protozoan parasite that has worldwide distribution and is responsible for enormous economic losses in cattle. Birds are considered a good bioindicator of environmental contamination, since they feed on the ground, being exposed to N. caninum oocysts. The aim of this study was to determine the occurrence of antibodies against N. caninum and to verify the presence of parasite DNA in brain from free-ranging eared doves (Zenaida auriculata) from Southern Brazil. For this purpose, blood and brain samples were collected from 249 doves for ELISA and PCR analysis respectively. The prevalence of N. caninum antibodies in doves was 31.72% (79/249) and detection of parasite DNA was not observed in none of birds. This is the first report of antibodies against N. caninum in doves Z. auriculata, what show us that these birds had previously contact with the parasite but since no N. caninum DNA was detected, more studies should be performed to elucidate the real importance of doves in the epidemiologic cycle of the N. caninum.

Abstract
AIM This study is part of an active surveillance program for monitoring animal health status in endangered species, and was conducted to screen captive Barbary sheep (Ammotragus lervia) for hemoplasma infection. MATERIALS AND METHODS A total of 12 blood samples were collected, DNA extracted and further tested by a pan-hemoplasma polymerase chain reaction protocol. RESULTS Animals were clinically healthy and not infested by ectoparasites. Although housekeeping gene DNA was successfully amplified, all the Barbary sheep samples tested negative for Mycoplasma sp. CONCLUSION Notwithstanding the negative results, molecular pathogen surveys on Barbary sheep and other exotic wild mammals may provide insights regarding infection of endangered species caused by captivity stress in association with exposure to new pathogens worldwide.

Abstract
Although the infection by Toxoplasma gondii in horses is usually asymptomatic, it may be characterized by the presence of tissue cysts and maintenance of detectable antibody titers. The aim of this study was to detect anti-T.gondii antibodies and to determine risk factors associated in sport horses from Paraíba State, Northeastern Brazil. A total of 138 apparently healthy sport horses of different age and gender were sampled. Anti-Toxoplasma gondii antibodies were detected in 16/138 (11.6%; 95% CI: 6.77-18.14%) horses by indirect immunofluorescence antibody assay (IFA). A significant association was found between the water source and seropositivity to T. gondii (p<0.05). The present study highlights the importance of providing good quality water to the animals.

Abstract
ABSTRACT: Hemoparasitic infections are tick-borne diseases, which affect animals and humans. Considering the importance of canine hemoparasitic infections in veterinary clinics, this study aimed to determine the occurrence of Anaplasma platys, Ehrlichia canis and Babesia vogeli in blood samples from 182 dogs not domiciled in the city of Pato Branco, southwestern region of Paraná State, Brazil, using polymerase chain reaction (PCR). The prevalence of A. platys and B. vogeli was 32.9% and 10.9% respectively, and A. platys infection prevailed (p<0.001). The number of dogs positive for A. platys was larger in Winter (p<0.05). All blood samples were negative for E. canis. In the dogs, infestation by Amblyomma cajennense predominated over that by Rhipicephalus sanguineus (p<0.001); but there was no significant association between PCR and the variables presence of ticks, sex and age. Dogs infected by A. platys and B. vogeli showed thrombocytopenia, lymphopenia and leukocytosis; but there was no correlation between such hematological changes and infection by hemoparasites. This appears to be the first molecular study that demonstrates the existence of A. platys and B. vogeli in dogs from the southwestern region of Paraná.

Abstract
The aims of the present study were to serosurvey dogs, horses, and humans highly exposed to tick bites for anti-Borrelia burgdorferi s.l. antibodies, identify tick species present, and determine risk factors associated with seropositivity in a rural settlement of Paraná State, southern Brazil. Eighty-seven residents were sampled, along with their 83 dogs and 18 horses, and individual questionnaires were administered. Immunofluorescence antibody test (IFAT) was performed on serum samples and positive samples were subjected to western blot (WB) analysis. Anti-B. burgdorferi antibodies were found in 4/87 (4.6%) humans, 26/83 (31.3%) dogs, and 7/18 (38.9%) horses by IFAT, with 4/4 humans also positive by WB. Ticks identified were mostly from dogs and included 45/67 Rhipicephalus sanguineus, 21/67 Amblyomma ovale, and 1/67 A. cajennense sensu lato. All (34/34) horse ticks were identified as A. cajennense s.l.. No significant association was found when age, gender, or presence of ticks was correlated to seropositivity to Borrelia sp. In conclusion, although anti-Borrelia antibodies have been found in dogs, horses and their owners from the rural settlement, the lack of isolation, molecular characterization, absence of competent vectors and the low specificity of the commercial WB kit used herein may have impaired risk factor analysis.

Abstract
Theileriosis is a worldwide protozoal tick-borne disease caused by Theileria equi, which may produce a variety of clinical signs and turn infected horses into lifetime carriers. This study has aimed to perform a serological and molecular detection of T. equi and associated factors in sports horses from six areas of northeastern Brazil. In overall, 59.6% horses were positive by indirect immunofluorescence assay and 50.4% by polymerase chain reaction. No significant association was found when presence of ticks, age, gender, anemia or total plasma proteins was analyzed with seropositivity and molecular techniques. Although a significant association of infection was found in two cities. Thus, local risk factors other than presence of ticks, horse age, gender, anemia and total plasmatic proteins may dictate prevalence of T. equi infection in sports horses, even in highly endemic areas with no control of infection prior to horse competitions.

Abstract
The aims of this study were to determine the prevalence of hemoplasmas in a rural Brazilian settlement's population of human beings, their dogs and horses, highly exposed to tick bites; to identify the tick species parasitizing dogs and horses, and analyze factors associated with their infection. Blood samples from 132 dogs, 16 horses and 100 humans were screened using a pan-hemoplasma SYBR green real-time PCR assay followed by a species-specific TaqMan real-time PCR. A total of 59/132 (44.7%) dog samples were positive for hemoplasmas (21 Mycoplasma haemocanisalone, 12 ' Candidatus Mycoplasma haematoparvum' alone and 21 both). Only 1/100 (1.0%) human sample was positive by qPCR SYBR green, with no successful amplification of 16S rRNA or 23 rRNA genes despite multiple attempts. All horse samples were negative. Dogs >1 year of age were more likely to be positive for hemoplasmas ( p= 0.0014). In conclusion, although canine hemoplasma infection was highly prevalent, cross-species hemoplasma transmission was not observed, and therefore may not frequently occur despite overexposure of agents and vectors.

Abstract
O agente de maior importância, em relação à anaplasmose bovina, é o Anaplasma marginale. Os principais sinais clínicos dessa enfermidade são anemia hemolítica, icterícia, dispneia, taquicardia, febre, fadiga, lacrimejamento, sialorreia, micção frequente, anorexia, perda de peso, aborto e morte. A terapia antimicrobiana é o principal protocolo terapêutico. O objetivo do presente trabalho foi avaliar a eficácia do dipropionato de imidocarb, da enrofloxacina e do cloridrato de oxitetraciclina no tratamento de bovinos leiteiros naturalmente infectados por Anaplasma marginale. Para isso, foram avaliados 48 zebuínos mestiços que apresentavam os sinais clínicos sugestivos da doença. Os animais foram submetidos à coleta de sangue para a realização de hemograma e à extração de DNA para a confirmação da presença de A. marginale, por meio da reação em cadeia pela polimerase (PCR). Os animais foram divididos em três grupos experimentais, para realização dos protocolos terapêuticos, utilizando-se dipropionato de imidocarb, oxitetraciclina e enrofloxacina. Trinta e seis animais (75%) apresentaram reação positiva ao PCR. Os animais positivos não apresentaram diferenças significativas quanto ao hemograma e ao leucograma quando comparados com os negativos, no entanto os níveis de proteínas séricas foram inferiores nos animais positivos (P<0,05). Os três protocolos terapêuticos foram capazes de reduzir a infecção ao longo do tratamento (P<0,01), porém, após cinco dias de tratamento, a enrofloxacina apresentou maior efetividade em relação aos demais (P<0,01). Após o final do tratamento, nenhum protocolo foi capaz de eliminar totalmente a infecção pelo A. marginale em bovinos naturalmente infectados e manejados a campo.

Abstract
Porcine enteropathogenic Escherichia coli (PEPEC) produce an outer membrane protein (intimin) called Paa (porcine attaching and effacing-associated), which is involved in the pathogenesis of E. coli in piglets with diarrhea. The paa gene of a PEPEC strain isolated in Paraná, Brazil, was amplified by polymerase chain reaction, sequenced, and cloned into the pTrcHisTOPO2 vector. The deduced amino acid sequence encoded by the paa gene of PEPEC from Paraná, Brazil, showed 99% homology to the sequences from other PEPEC strains. In this study, the overexpression of recombinant Paa (rPaa) using alternative induction strategies was attempted. The auto-induction protocol showed excellent results for rPaa protein production with 0.4% (w/v) lactose. The rPaa protein is insoluble and was purified with Triton X-100 wash as a total antigen. This method produced a relatively high yield of rPaa. rPaa was recognized by serum from pigs immunized with the PEPEC strain. These results suggest that rPaa could be included in the development of a vaccine against swine colibacillosis.

Abstract
This study describes the detection of Borrelia garinii and Borrelia
burgdorferi sensu stricto (s.s.) in Brazilian individuals using PCR
and DNA sequencing. Our results suggest that these species are emerging
pathogens in this country, and additional studies are necessary to determine the
epidemiological characteristics of this disease in Brazil.

Abstract
Considering the zoonotic potential of tick-borne disease (TBD) agents and the fact that dogs may act as sentinels for human infection, the aim of the present study was to determine the seroprevalence of TBD agents and risk factors for exposure in two different canine populations from Parana State, Southern Brazil. A total of 138 dog serum samples from urban (UA) (n=68) and rural (RA) (n=70) areas were tested with commercial ELISA rapid test for Anaplasma phagocytophilum, Ehrlichia canis and Borrelia burgdorferi antibodies and indirect immunofluorescence assay (IFAT) for Babesia vogeli. An overall of 92∕138 (66.7%) dogs, being 62∕68 (91.2%) from UA and 30∕70 (42.9%) from RA, were seropositive for at least one TBD agent. From the total number of dogs, sixty-two were positive for E. canis (44.9%), 19 (13.8%) for A. phagocytophilum, and 64 (46.4%) for B. vogeli. Anti-B. burgdorferi antibodies were not detected. Dogs from UA showed a higher percentage of tick infestation (p = 0.0135) and were highly associated with seropositivity to E. canis (p = 0.000005), A. phagocytophilum (p = 0.0001), and B. vogeli (p = 0.0012). In summary, the findings indicate that dogs from urban areas present higher potential risk exposure to TBD pathogens than those from rural areas.

Abstract
Eared doves (Zenaida auriculata), which are common in urban, rural and wild areas in many regions of Brazil, are frequently prey for domestic cats. Therefore Toxoplasma gondii isolates obtained from doves may reflect greater environmental diversity than those from other hosts. The aim of the present study was to evaluate T. gondii seroprevalence, isolate and genotype strains from Z. auriculata. Serum and tissue samples were collected from 206 doves for use in the modified agglutination test (MAT) and mouse bioassay. The prevalence of T. gondii antibodies in the doves was 22.3% (46/206), with titers ranging from 16 to 4096, and T. gondii strains were isolated from 12 of these doves. Five genotypes were detected by means of PCR-RFLP, including ToxoDB genotypes #1, #6, #17 and #65, and one genotype that had not previously been described (ToxoDB#182). This was the first report on isolation of T. gondii from Z. auriculata. This study confirmed the genetic diversity of T. gondii isolates and the existence of clonal type II (ToxoDB genotype #1) in Brazil.

Abstract
Despite our current knowledge of the immunology, pathology, and genetics of Anaplasma marginale, prevention in cattle is currently based on old standbys, including live attenuated vaccines, antibiotic treatment, and maintaining enzootic stability in cattle herds. In the present study, we evaluated the use of an immunostimulant complex (ISCOMATRIX) adjuvant, associated with a pool of recombinant major surface proteins (rMSP1a, rMSP1b, rMSP4 and rMSP5) to improve the humoral immune response triggered in calves mainly by IgG2. Ten calves were divided in three groups: 4 calves were inoculated with the ISCOMATRIX/rMSPs (G1); 2 calves were inoculated with ISCOMATRIX adjuvant (G2); and 4 calves received saline (G3). Three inoculations were administered at 21-day intervals. In G1, the calves showed significant increases in total IgG, IgG1 and IgG2 levels 21 days after the second inoculation, compared to the control group (p < 0.05), and G1 calves remained above the cut-off value 28 days after the third inoculation (p < 0.05). The post-immunized sera from calves in G1 reacted specifically for each of the rMSPs used. In conclusion, the ISCOMATRIX/rMSPs induced antigen-specific seroconversion in calves. Therefore, additional testing to explore the protection induced by rMSPs, both alone and in conjunction with proteins previously identified as subdominant epitopes, is warranted.

Abstract
The aims of this study were to determine the seroprevalence of Ehrlichia spp. and risk factors for exposure in a restricted population of dogs, horses, and humans highly exposed to tick bites in a Brazilian rural settlement using a commercial ELISA rapid test and two indirect immunofluorescent assays (IFA) with E. canis and E. chaffeensis crude antigens. Serum samples from 132 dogs, 16 horses and 100 humans were used. Fifty-six out of 132 (42.4%) dogs were seropositive for E. canis. Dogs > one year were more likely to be seropositive for E. canis than dogs ≤ one year (p = 0.0051). Ten/16 (62.5%) and 8/16 (50%) horses were seropositive by the commercial ELISA and IFA, respectively. Five out of 100 (5%) humans were seropositive for E. canis and E. chaffeensis. Rhipicephalus sanguineus (n = 291, 97.98%) on dogs and Amblyomma cajennense (n = 25, 96.15%) on horses were the most common ticks found. In conclusion, anti-Ehrlichia spp. antibodies were found in horses; however, the lack of a molecular characterization precludes any conclusion regarding the agent involved. Additionally, the higher seroprevalence of E. canis in dogs and the evidence of anti-Ehrlichia spp. antibodies in humans suggest that human cases of ehrlichiosis in Brazil might be caused by E. canis, or other closely related species.

Abstract
The aim of this study was to investigate the presence of DNA of Borrelia burgdorferi sensu lato (s.l.) in ticks that feed on horses used for animal traction in rural Jataizinho, Parana, Brazil. Between February and June 2008, a total of 224 ticks was collected of which 75% were identified as Dermacentor nitens and 25% as Amblyomma cajenense. To amplify B. burgdorferi s.l. DNA, the intergenic space region (ISR) between the 5S (rrf) 23S (rrl) rRNA genes was used as targets for nested-PCR. Two ticks of the D. nitens species were positive for B. burgdorferi s.l. Both species showed a fragment of 184 bp, but the sequencing revealed 99.9% homology with the B. burgdorferi sensu stricto (s.s.) strain B31. These results showed, for the first time, the presence of spirochete DNA infecting ticks that parasitize horses used for animal traction, in the rural municipality mentioned. In conclusion, this study opens up promising prospects for determining the infection rate of B. burgdorferi s.s. genospecies or other species in the equine population, as well as the impact of the infection rate on Lyme disease in the state of Parana.

Abstract
Bovine hemoplasmas are bacteria found on the erythrocyte surface or free in the plasma of cattle. The aim of the present study was to evaluate the occurrence of 'Candidatus Mycoplasma haemobos' ('C. M. haemobos') in Holstein and Jersey cattle raised in Londrina and surroundings, northern region of the State of Parana, Southern Brazil. PCR testing directed to 16S rRNA gene fragment was performed to investigate the occurrence and characterize the molecular identity of 'C. M. haemobos'. A total of 264/433 (60.97%) blood samples were positive by PCR. Further alignment of 500-bp amplicons to available sequences at the GenBank database showed high identity (100%) to 'C. M. haemobos'. To the author's knowledge, this is the first molecular confirmation of the hemoplasma 'C. M. haemobos' in cattle from Brazil. Moreover, 'C. M. haemobos' was observed in high occurrence in dairy cattle, and may have significant impact in livestock production.

Abstract
The objective of this study was to evaluate the seroepidemiological data of Babesia caballi and Theileria equi in horses from a rural settlement and carthorses from urban areas of Paraná State, southern Brazil. A total of 198 horses, including 32 from the rural settlement and 166 carthorses from Colombo (n=48), Pinhais (n=76), Londrina (n=24), and Curitiba city (n=18) was sampled and tested using a commercial competitive inhibition ELISA (cELISA) test. Out of the 198 horses, 193 (97.5%) were seropositive for at least one piroplasm species. Antibodies to T. equi were detected in 155/198 horses (78.3%), antibodies to B. caballi were detected in 137/198 horses (69.2%), and antibodies to both were detected in 99/198 (50.0%) horses. Horses living in the rural settlement and Colombo were more likely to be seropositive to T. equi than those in Curitiba (p<0.05). Horses older than 5 years were more likely to be seropositive for T. equi than those younger than 5 years (p<0.05). No significant association was found between gender or the presence of ticks and seropositivity to T. equi (p>0.05). In conclusion, the high seroprevalences to B. caballi and T. equi observed in this study emphasize that active surveillance programs are critical for monitoring animal health status, particularly because carthorses may act as urban disseminators of these piroplasms.

Abstract
This study aimed to determine the prevalence of gastrointestinal and renal helminths from naturally infected Zenaida auriculatacaptured in Londrina, Paraná State. Two hundred and one Eared doves were trapped and the gastrointestinal and renal helminths were collected and identified according to morphological structures. One hundred and sixteen (57.71%) doves were parasitized by helminths with specific prevalences forOrnithostrongylus quadriradiatus in 50 doves (24.88%),Ascaridia columbae in 47 (23.38%), Paratanaisia bragai and P. confusa in 34 (16.92%),Tetrameres fissispina in 17 (8.46%), Synhimantus nasuta in 14 (6.47%), Brachylaima mazzantii in 4 (1.99%) and Raillietina allomyodes in 2 doves (1.00%). Seventy four/201 (37.00%) birds were infected with only one species, and 96/201 (48.00%) pigeons were infected with nematodes. The association between different classes of helminths occurred in 40/201 (20.00%) animals. The results showed statistically differences between the presence of nematode (p = 0.00001) and trematode species (p ≤ 0.05) in the doves, and there was an association between the local of capture and the presence of trematodes and A. columbae (p ≤ 0.05). This study is the first to report the infection of Z. auriculata from Brazil with O. quadriradiatus, A. columbae, T. fissispina, S. nasuta, R. allomyodes, P. bragai and P. confusa.

Abstract
Canine monocytic ehrlichiosis caused primarily by Ehrlichia canis and canine thrombocytic anaplasmosis induced by Anaplasma platys are important emerging zoonotic tick-borne diseases of dogs. There is evidence that these pathogens can also affect humans. This study evaluated the presence of E. canis and A. platys in blood samples collected from 256 domiciled dogs in the municipality of Jataizinho, located in north region of the State of Parana, Brazil, by PCR assay. The occurrence of E. canis and A. platys was 16.4% (42/256) and 19.4% (49/256), respectively; while 5.47% (14/256) of the dogs evaluated were co-infected by these two organisms. The presence of E. canis and A. platys was not significantly associated with the variables evaluated (sex, age, outdoor access, and presence of ticks during blood collection). Infection of dogs by E. canis was associated with anemia and thrombocytopenia, while infection induced by A. platys was related only to thrombocytopenia. Canine monocytic ehrlichiosis and canine thrombocytic anaplasmosis should be included in the differential diagnoses when these hematological alterations are observed during routine laboratory evaluation of dogs.

Abstract
Ehrlichiosis is a disease caused by rickettsial organisms belonging to the genus Ehrlichia. In Brazil, molecular and serological studies have evaluated the occurrence of Ehrlichia species in dogs, cats, wild animals and humans. Ehrlichia canis is the main species found in dogs in Brazil, although E. ewingii infection has been recently suspected in five dogs. Ehrlichia chaffeensis DNA has been detected and characterized in mash deer, whereas E. muris and E. ruminantium have not yet been identified in Brazil. Canine monocytic ehrlichiosis caused by E. canis appears to be highly endemic in several regions of Brazil, however prevalence data are not available for several regions. Ehrlichia canis DNA also has been detected and molecularly characterized in three domestic cats, and antibodies against E. canis were detected in free-ranging Neotropical felids. There is serological evidence suggesting the occurrence of human ehrlichiosis in Brazil but its etiologic agent has not yet been established. Improved molecular diagnostic resources for laboratory testing will allow better identification and characterization of ehrlichial organisms associated with human ehrlichiosis in Brazil.

Abstract
TgROP2 is an intracellular protein associated with rhoptries of Toxoplama gondii and an antigen component of a candidate vaccine for toxoplasmosis. The purpose of the present study was to evaluate the efficacy of rTgROP2 to stimulate humoral and cellular immune responses in BALB/c mice via intranasal injection. TgROP2 partial coding sequence was (196-561) amplified by PCR from genomic T. gondii RH strain DNA and cloned into the pTrcHis expression vector. Escherichia coli Rosetta 2 cells transformed with pTrcHis-TgROP2 showed high levels (~1 mg.mL(-1)) of recombinant protein after 4 hours of IPTG induction. Recombinant TgROP2 exhibited an apparent Mr equal to 54 kDa. In order to test immunogenicity of the recombinant protein, 10 BALB/c mice received 10 µg of rROP2 protein + 10 µg of Quil-A via intranasal injection. Doses were administered at days 0, 21, and 42. Three animals were euthanized and used to evaluate cellular immune response on day 62. Five (50%) and two (20%) out of ten animals produced IgG (DO mean = 0.307; cut-off = 0.240) and IgA (DO mean = 0.133, cut-off = 0.101), respectively, by ELISA on day 62. The proliferation of splenocytes revealed high stimulation index (SI) when co-cultured with 5, 10 and 15 µg.mL(-1) of rTgROP2. These results indicate that intranasal immunization with recombinant protein ROP2 plus Quil-A can elicit both cellular and humoral immune responses in BALB/c mice.

Abstract
Brazilian spotted fever (BSF) is an emerging disease most likely caused by Rickettsia rickettsii. The objective of the present study was to estimate the seroprevalence of BSF rickettsia infections in equines from six horse farms located in Londrina County, Paraná, Southern Brazil. Six owners of horse farms situated in Cambé, Santa Fé, Guaraci and Londrina municipalities participated in the study. All farms were located in areas where BSF has not been reported. A total of 273 horses were sampled and their sera were tested by indirect immunofluorescence assay (IFA) using R. rickettsii and R. parkeri antigens. Titers equal to and greater than 64 were considered positive. Of 273 sera tested, 15 (5.5%) reacted to R. rickettsii and 5 (1.8%) to R. parkeri. Five out of the six farms studied revealed seropositive animals and seropositivity rate ranged from 0 to 13%. The titers ranged from 64 to 512, and four samples had a titer of 512. Nine animals reacted to R. rickettsii with titers four-fold higher than those for R. parkeri. These results suggest that horses in Northern Paraná may have been exposed to rickettsiae identical or closely related to R. rickettsii.

Abstract
INTRODUCTION: Spotted fevers are emerging zoonoses caused by Rickettsia species in the spotted fever group (SFG). Rickettsia rickettsii is the main etiologic agent of Brazilian spotted fever (BSF) and it is transmitted by Amblyomma spp. ticks. METHODS: The study aimed to investigate SFG rickettsiae in the Arthur Thomas Municipal Park in Londrina, PR, by collecting free-living ticks and ticks from capybaras and blood samples from personnel working in these areas. Samples from A. dubitatum and A. cajennense were submitted for PCR in pools to analyze the Rickettsia spp. gltA (citrate synthase gene). RESULTS: All the pools analyzed were negative. Human sera were tested by indirect immunofluorescence assay with R. rickettsii and R. parkeri as antigens. Among the 34 sera analyzed, seven (20.6%) were reactive for R. rickettsii: four of these had endpoint titers equal to 64, 2 titers were 128 and 1 titer was 256. None of the samples were reactive for R. parkeri. An epidemiological questionnaire was applied to the park staff, but no statistically significant associations were identified. CONCLUSIONS: The serological studies suggest the presence of Rickettsiae related to SFG that could be infecting the human population studied; however, analysis of the ticks collected was unable to determine which species may be involved in transmission to humans.

Abstract
Mycoplasma suis is a hemotropic bacteria of red blood cells and the causative agent of swine eperythrozoonosis. Diagnosis of infection may be reached by direct examination of blood smears; however, the use of polymerase chain reaction (PCR) of the 16S RNA gene of M. suis improves the sensitivity and specificity of detection. The aim of this study was to screen peccaries (Tayassu tajacu and T. pecari) for M. suis infection using a specific conventional PCR. A total of 28 blood samples from captive collared and white-lipped peccaries were collected, DNA extracted and a specific M. suis PCR assay performed. All samples were negatives by both blood smear examination and PCR testing. To verify the presence of amplifiable DNA, PCR for beta-actin gene was performed in all samples. This study was part of an active surveillance program, which is crucial for monitoring animal health status, particularly in wildlife species.

Abstract
Spotted fever is a disease caused by bacteria from the genus Rickettsia of the spotted fever group (SFG). Rickettsia rickettsii is likely the main agent of Brazilian spotted fever (BSF). With the objective of gathering information on the circulation of SFG rickettsiae in Londrina, Parana state, ticks from dogs and horses and also blood from dogs, horses and humans were collected in a neighbourhood of the city which presented potential for circulation of rickettsiae between hosts and vectors. Amblyomma cajennense, Dermacentor nitens, and Rhipicephalus sanguineus ticks were subjected to Polymerase Chain Reaction targeting a fragment of the Rickettsia gltA gene. This specific gene encodes the enzyme citrate synthase of Rickettsia spp., and results on all ticks were negative. Human and animal sera were tested by Indirect Immunofluorescence Assay in which R. rickettsii and R. parkeri were used as antigens. Sera from 4.7% human, 2.7% canine and 38.5% equine were positive for R. rickettsii. For R. parkeri, 0.9% human, 2.7% canine and 11.5% equine samples were positive. All samples reactive to R. parkeri also reacted to R. rickettsii. An epidemiological questionnaire was applied, but there were no statistically significant results. Comparison of our serological results with previous studies in Brazil, among BSF endemic and non-endemic areas, indicates that there is no established rickettsial infection in the study area, a statement corroborated with our molecular analysis. Nonetheless, as humans of the present study are highly exposed to tick infestations, health education within the population is needed to obtain efficient tick control.

Abstract
Neorickettsia helminthoeca is an obligate intra-cytoplasmic bacterium that causes salmon poisoning disease (SPD), an acute, febrile, fatal disease of dogs. The complex life-cycle of this pathogen involves stages in an intestinal fluke (Nanophyetus salmincola), a river snail (Oxytrema silicula), in fish, and in fish-eating mammals. This complexity has created confusion with respect to the various bacterial and parasitic infections associated with the disease and its significance in dogs in specific geographical locations has likely to have previously been under-estimated. This paper addresses the history, taxonomy, microbiology of N. helminthoeca and summarises the pathogenesis, clinical signs and pathological features associated with infection. Furthermore, the biological cycles, treatment, control, and both public and veterinary health impacts associated with this pathogen and the intestinal fluke N. salmincola are discussed.

Abstract
A competitive enzyme-linked immunosorbent test using the PR1 recombinant major surface protein 5 (rMSP5-PR1-ELISA) of Anaplasma marginale was standardized and validated using sera from anaplasmosis free and endemic regions. The sequencing of the msp5 gene of PR1 isolate showed 98% of identity with the Florida and Saint Maries isolates, 97% with Brazil (Pernambuco) and Havana isolates; and 91% with A. centrale. The cELISA-PR1 test was compared to IFI and cELISA-USA. For the standardization and validation of the cELISA-PR1, 380 bovine sera were used, whereas 245 truly positives and 135 truly negatives sera tested by the cELISA-USA. In the standardization of the cELISA-PR1 135 negative and 148 positive bovine sera were used. The cELISA-PR1 and IFI tests showed 100 and 99.3% specificity, 100 and 98%, sensibility, and a kappa coefficient of 0.993 and 0.978, respectively. For test validation, 245 bovine sera from an anaplasmosis endemic area were analyzed by the cELISA-PR1 and IFI, which showed 96.7 and 69.1% specificity, 98.9 e 96.3% sensibility and kappa coefficient of 0.956 and 0.699, respectively. These results indicate that the cELISA-PR1, likewise the cELISA-USA, could sensitively and specifically detect cattle naturally infected with A. marginale and would be recommended for epidemiological studies, eradications program, and regulation of international cattle movement, while IFI, which presented lower specificity should not be used in situations that demand more specific diagnosis.

Abstract
Anaplasma marginale, a tick-borne bacterium, causes bovine anaplasmosis responsible for significant economic losses in tropical and subtropical regions worldwide. Various major outer membranes have been described, and VirB9, a type IV secretion system protein, has been recently indicated as a candidate in vaccine development against anaplasmosis. The virB9 gene of an A. marginale strain isolated in Paraná, Brazil, was cloned by polymerase chain reaction and sequenced; its cloning into the pETSUMO vector produced a virB9-SUMO-6x His fusion gene construct. This recombinant clone was over-expressed in Escherichia coli BL21 (DE3), and the expressed fusion protein was solubilized with urea and purified with an Ni-NTA column. This method produced a relatively high yield of rVirB9. The deduced amino acid sequence encoded by VirB9 showed 99% homology to A. marginale isolates from St. Maries. rVirB9 was recognized by serum from cattle immunized with PR1 strain and by bovine sera infected with heterologous strains, showing that rVirB9 has conserved epitopes, which suggests that rVirB9 could be useful for the development of a vaccine against anaplasmosis.

Abstract
Canine babesiosis is a worldwide disease caused by the protozoan of Babesia genus. Babesia canis and B. gibsoni are both species that naturally infect dogs. The objective of this study was to evaluate the infection of Babesia species in dogs attended at the Londrina State University Veterinary Teaching Hospital (HV-UEL). It was selected 282 dogs seen at the Londrina State University Veterinary Teaching Hospital (HV-UEL) between April of 2005 and May of 2006. They presented anemia (Packed Cell Volume<25%), thrombocytopenia (Platelet count <150000/mm3), leukopenia (White blood cell count<5000/mm3) or a combination of two or three of these alterations at the moment of the consultation. The presence of Babesia sp was determined by the amplification of a specific fragment of DNA of the Babesia genus by PCR. Microscopic examination of Giemsa-stained blood smears detected 38 (13.5%) positive samples against 105 identified by PCR from 282 dogs. The positive samples were submitted to PCR-RFLP by Hinf I that allows distinguishing the species of B. canis vogeli and B. gibsoni. From 282 dogs, Babesia sp infection was identified in 105 (37.2%). From these 105 positive samples, the PCR-RFLP identified 66 (23.4%) samples with a profile compatible to B. canis vogeli and 39 (13, 8%) to B. gibsoni. As conclusions, the results obtained allow to affirm that the babesiose is an important differential for dogs that present anemia, leukopenia and thrombocytopenia and, B. canis vogeli is the subspecies that is present in the most of the cases of babesiose in the population of dogs studied and, that B. gibsoni is also present causing babesiosis in dogs of the Londrina region, Parana State, Brazil.
