Applying MALDI-TOF MS to resolve morphologic and genetic similarities between two Dermacentor tick species of public health importance. Sci Rep 2024; 14:19834. [PMID: 39191821 DOI: 10.1038/s41598-024-69768-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Accepted: 08/08/2024] [Indexed: 08/29/2024] Open
Abstract
Hard ticks (Acari: Ixodidae) have been historically identified by morphological methods which require highly specialized expertise and more recently by DNA-based molecular assays that involve high costs. Although both approaches provide complementary data for tick identification, each method has limitations which restrict their use on large-scale settings such as regional or national tick surveillance programs. To overcome those obstacles, the matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been introduced as a cost-efficient method for the identification of various organisms, as it balances performance, speed, and high data output. Here we describe the use of this technology to validate the distinction of two closely related Dermacentor tick species based on the development of the first nationwide MALDI-TOF MS reference database described to date. The dataset obtained from this protein-based approach confirms that tick specimens collected from United States regions west of the Rocky Mountains and identified previously as Dermacentor variabilis are the recently described species, Dermacentor similis. Therefore, we propose that this integrative taxonomic tool can facilitate vector and vector-borne pathogen surveillance programs in the United States and elsewhere.

[PMID: 38399789 PMCID: PMC10892289 DOI: 10.3390/microorganisms12020385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 02/07/2024] [Accepted: 02/08/2024] [Indexed: 02/25/2024] Open
Abstract
The spirochete Borrelia burgdorferi sensu lato (Lyme Group) is the causative agent of Lyme disease, transmitted to humans through tick bites carrying the bacteria. Common symptoms include fever, headache, fatigue, and the characteristic erythema migrans skin rash. If left untreated, the infection can affect joints, the cardiac system, and the nervous system. Diagnosis relies on symptoms, clinical signs (such as the rash), and potential exposure to infected ticks, with laboratory tests proving valuable when appropriately employed with validated methods. Most cases of Lyme disease respond effectively to a few weeks of antibiotic treatment. In Latin America, knowledge of Lyme disease is limited and often confounded, underscoring the significance of this review in aiding medical professionals in recognizing the disease. This study delves explicitly into Lyme disease in Argentina, neighboring countries, and other Latin American nations.

Argas persicus and Carios vespertilionis Ticks Infesting Ducks, Domestic Fowls and Bats in Pakistan: First Report on Molecular Survey and Phylogenetic Position of Borrelia anserina. Vet Sci 2023; 10:628. [PMID: 37888580 PMCID: PMC10610582 DOI: 10.3390/vetsci10100628] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 10/10/2023] [Accepted: 10/12/2023] [Indexed: 10/28/2023] Open
Abstract
Argasid ticks have the vectorial potential for transmitting disease-causing pathogens to avian hosts, resulting in economic losses that may not be fully estimated. Borrelia species are the responsible agents of borreliosis in poultry, animals and humans. Our previous studies have reported a high prevalence of Argas persicus infesting domestic fowls in Khyber Pakhtunkhwa (KP), Pakistan. However, molecular screening and genetic characterization of Borrelia spp. in A. persicus have been neglected in Pakistan. In this study, we focused on the molecular epidemiology and genetic characterization of Borrelia spp. associated with A. persicus ticks infesting domestic fowls and ducks, and Carios vespertilionis infesting bats in selected districts of KP. Overall, 1818 ticks, including females (415; 23%), males (345; 19%), nymphs (475; 26%) and larvae (583; 32%), were collected from 27 locations in nine districts (Peshawar, Mardan, Swabi, Charsadda, Chitral, Lakki Marwat, Bannu, Bajaur and Hangu) from domestic fowls, ducks and their shelters, and bats. A subset of 197 ticks was selected for DNA extraction and PCR to amplify fragments of the cytochrome c oxidase (cox) gene for ticks and flagellin B (flaB) for the detection and genetic characterization of associated Borrelia spp. Among these, only Borrelia anserina DNA was detected in 40 ticks (27.2%) of different life stages, where highest prevalence was found in female ticks (18; 45%), followed by nymphs (12; 30%), larvae (7; 17.5%) and males (3; 7.5%). Tick infestation in shelters (1081; 77%) was higher than on hosts (323; 23%). The resultant cox amplicons of A. persicus showed 100% identity with the same species reported from Pakistan, China, Iran, Kenya, Kazakhstan, Algeria and Egypt and C. vespertilionis show 100% identity with the species reported from Pakistan, China, Japan, Kenya, Vietnam, Spain, Netherlands, the United Kingdom and Hungry, and clustered with the aforementioned species in the phylogenetic tree. The obtained Borrelia sequences showed 100% identity with B. anserina and revealed a close resemblance to the relapsing fever group and clustered in a monophyletic clade with B. anserina from India, Iran and Brazil in a phylogenetic tree. These results establish the first molecular characterization of B. anserina in A. persicus infesting domestic fowls and ducks in the region, as well as their shelters. To effectively control zoonotic consequences, country-wide surveillance research should be encouraged to screen soft ticks infesting various birds for associated pathogens.

Analysis of the tick communities associated to domestic mammals in rural areas of the Yungas montane forest from Argentina. Vet Parasitol Reg Stud Reports 2023; 39:100850. [PMID: 36878633 DOI: 10.1016/j.vprsr.2023.100850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 02/11/2023] [Accepted: 02/16/2023] [Indexed: 02/22/2023]
Abstract
The aim of this work was to describe the tick community associated to domestic mammals in rural areas from the Yungas lower montane forest of Argentina. The circulation of tick-borne pathogens was also analyzed. Samples of ticks parasitizing cattle, horses, sheep and dogs were carried out in different seasons, and questing ticks were collected from vegetation and analyzed to detect the presence of Rickettsia, Ehrlichia, Borrelia and Babesia by a battery of different PCRs. The structure of the tick communities was analyzed through the Chao1 species richness estimator, the Shannon-Wiener index and the Horn index of community similarity. Eight tick species were collected in the study area: Amblyomma sculptum, Rhipicephalus microplus, Amblyomma hadanii, Dermacentor nitens, Amblyomma ovale, Haemaphysalis juxtakochi, Ixodes pararicinus and Rhipicephalus sanguineus sensu stricto. However, A. sculptum was by far the dominant species in the tick assemblages analyzed, and this was reflected in the low diversity values obtained. Dermacentor nitens, A. sculptum and R. microplus were the three species associated to horses. The predominance of A. sculptum was also observed in the tick samples obtained from dogs, even on two tick species, namely A. ovale and R. sanguineus s.s., which have dogs as the principal domestic host. Rhipicephalus microplus and A. sculptum were the most abundant ticks on cattle, while few specimens of I. pararicinus, A. hadanii and D. nitens were found on bovines. Dermacentor nitens ticks were found to be infected with B. caballi, which indicate the circulation of this pathogen of horses in the Yungas area. The detection of a strain of Borrelia sp. belonging to the B. burgdorferi s.l. complex in I. pararicinus is consistent with previous findings made in Argentina, but the public health relevance of this vector-microorganism association is far from being similar to that occurs in the northern hemisphere because there are practically no records of these tick species parasitizing humans in South America. The tick community of rural areas of the Yungas lower montane forest is composed by species which are potential vectors of pathogenic microorganism with veterinary and public health importance, circulating in a human-wildlife-livestock interface.

Abstract
Borrelia burgdorferi sensu lato (Bbsl) spirochetes include the agents of Lyme borreliosis in temperate regions of the Northern Hemisphere, and merge their transmission cycles mainly with ticks of the Ixodes ricinus complex. Twenty genospecies compose Bbsl currently, and with the exception of Borrelia chilensis, and Borrelia garinii, all have been described only for North America, Europe, North Africa, and Asia. Here, we collected specimens of Ixodes paranaensis, a tick associated with swifts in a Brazilian natural park from the state of Minas Gerais, and performed a molecular characterization of 11 borrelial genes. Based on comparisons of inter and intraspecific genetic divergences, and Bayesian phylogenetic trees inferred for 16S rRNA, flaB, p66, and concatenated clpA, clpX, pepX, pyrG, recG, nifS rlpB, and uvrA genes, we demonstrate the occurrence of a new genospecies of Bbsl. "Candidatus Borrelia ibitipoquensis" Ip37 is closely related to Borrelia sp. Am501, and Borrelia valaisiana, a spirochete transmitted by ticks of the I. ricinus complex in Eurasia that uses birds as reservoirs. In a similar ecological scenario involving ticks and avian hosts, the migratory swift Streptoprocne biscutata is the sole-documented bird associated with I. paranaensis, and, although not assessed in this study, could correspond to the vertebrate reservoir of this newly described genospecies in Brazil. Pathogenic roles of "Ca. B. ibitipoquensis" are still unknown. However, its possible vector I. paranaensis is not an anthropophilic tick, so human infections would be unlikely to occur. Our finding enhances the knowledge on Bbsl in South America, highlights the occurrence of ecologically and genetically related genospecies with vastly separated geographical distributions, and calls for the attention to explore a barely known diversity of spirochetes of this group in the region.

Abstract
The aim of this work was to evaluate the presence of Borrelia infection in Ixodes sp. cf. Ixodes affinis ticks from Argentina. Specimens of Ixodes sp. cf. I. affinis were collected on vegetation and birds in five locations belonging the most humid part of the Chaco Biogeographic Province. Specimens were tested for Borrelia infection by nested-PCR targeting the flaB gene and the rrfA-rrlB intergenic spacer region (IGS), sequenced and phylogenetically analyzed. A total of 48 Ixodes sp. cf. I. affinis (12 questing adults from vegetation and 20 nymphs and 16 larvae on nine bird species: Arremon flavirostris, Basileuterus culicivorus, Campylorhamphus trochilirostris, Myiothlypis leucoblephara, Tachyphonus rufus, Thlypopsis sordida, Turdus amaurochalinus, Turdus rufiventris and Troglodytes aedon) were collected. Twelve adults, 14 nymphs and 11 larvae (3 individually and 8 in 3 pools) were analyzed. Partial sequences were detected in 6 adults, 11 nymphs and 4 larvae (2 individual and 2 pools). Phylogenetically, the Borrelia found in Ixodes sp. cf. I. affinis belongs to the B. burgdorferi sensu lato (s. l.) complex. The partial sequences obtained from the borrelian gene flaB and IGS were associated to two groups formed by sequences previously detected in Ixodes fuscipes, Ixodes longiscutatus and Ixodes pararicinus from the Southern Cone of America in northern Argentina, southern Brazil and Uruguay. The results of this work suggest that the haplotypes of B. burgdorferi s. l. complex detected in the three species of the I. ricinus complex distributed in the Southern Cone of America are related and widely distributed.

Abstract
Gram-negative spirochetes of the genus Borrelia are transmitted to vertebrate hosts through the tick bite during blood intake. Pathogenic Borrelia species may cause relapsing fever or Lyme borreliosis in humans. Our study aimed to molecularly detect and characterize bacteria of this genus in ticks collected in the Iguaçu National Park, located in southern Brazil. Ticks were collected from the environment (free living) and from hosts from May 2015 to July 2017. In total, 829 ticks were tested, being 741 from the environment and 88 from hosts; 128 ticks were larvae, 523 were nymphs, and 178 were adults (80 males and 98 females). The species identified were: Amblyomma brasiliense (42.9 %), Amblyomma coelebs (16.8 %), Amblyomma sp. (15.0 %), Amblyomma incisum (10.3 %), Amblyomma ovale (8.7 %), Haemaphysalis juxtakochi (5.5 %), Rhipicephalus microplus (0.5 %), Amblyomma longirostre (0.2 %), and Rhipicephalus sanguineus sensu lato (0.1 %). DNA extraction was performed with pools of larvae or nymphs, or individually with adults, for a total of 394 samples. The PCR technique used to detect Borrelia DNA was performed with two rounds of amplification reactions targeting a segment of the flagellin B gene (flaB). Amplification occurred in only one DNA sample, which was obtained from nymphs of A. brasiliense collected from the vegetation of a trail. The nucleotide sequence analysis revealed 90.8 % identity to a sequence of Borrelia sp. from Côte d'Ivoire, and 89.1 % identity to a sequence from Ethiopia. Phylogenetic analysis revealed that the Borrelia sequence from A. brasiliense was distinct from the Borrelia species of the groups belonging to Lyme borreliosis, relapsing fever and the one associated with reptile and echidna as hosts. The sequence is likely from a putative new species of Borrelia and was detected for the first time in A. brasiliense ticks.

Abstract
In the southern cone of South America different haplotypes of Borrelia burgdorferi sensu lato (Bbsl) have been detected in Ixodes spp. from Argentina, southern Brazil, Chile, and Uruguay. So far, Lyme borreliosis has not been diagnosed in Uruguay and the medical relevance of the genus Ixodes in South America is uncertain. However, the growing number of new genospecies of Bbsl in the southern cone region and the scarce information about its pathogenicity, reservoirs and vectors, highlights the importance of further studies about spirochetes present in Uruguay and the region. The aim of this study was to determine the presence of Bbsl in Ixodes auritulus ticks collected from birds and vegetation in two localities of southeastern Uruguay. In total 306 I. auritulus were collected from 392 passerine birds sampled and 1110 ticks were collected by flagging in vegetation. Nymphs and females were analyzed for Borrelia spp. by PCR targeting the flagellin (fla) gene and the rrfA-rrlB intergenic spacer region (IGS). The phylogenetic analysis of Borrelia spp. positive samples from passerine birds and vegetation revealed the presence of four fla haplotypes that form a clade within the Bbsl complex. They were closely related to isolates of Borrelia sp. detected in I. auritulus from Argentina and Canada.

Abstract
Las garrapatas son artrópodos de gran impacto sobre la economía pecuaria y la salud humana debido a las pérdidas generadas en la producción, y a su capacidad de transmitir microorganismos. Pese a la evidencia de circulación de una gran diversidad de garrapatas en Colombia, no se cuenta con compilaciones actualizadas de la variedad de especies presentes, por lo cual los autores presentan una revisión de literatura sobre las garrapatas de la familia Ixodidae reportadas en Colombia incluyendo su distribución geográfica, sus hospederos y los microorganismos reportados en aquellas especies registradas en este país. En la recopilación se evidenció la presencia en Colombia de diferentes especies de garrapatas de los géneros Amblyomma, Ixodes, Haemaphysalis, Rhipicephalus y Dermacentor. El género con mayor variedad fue Amblyomma con 29 especies, seguido de Ixodes con 11 especies, y de los géneros Dermacentor, Haemaphysalis y Rhipicephalus se reportaron dos especies para cada uno. Las especies se distribuyeron en la mayoría de los departamentos de Colombia y en una amplia diversidad de hospederos entre los cuales se incluyen animales domésticos, sinantrópicos y silvestres. Adicionalmente se encontró que algunas garrapatas reportadas podrían jugar un papel como vectores potenciales de diversos microorganismos que pueden afectar a la salud pública y veterinaria. Esperamos que este trabajo sea un aporte para apoyar la investigación en garrapatas y el estudio de los agentes transmitidos por estas en Colombia.

Abstract
This study was aimed to know epidemiological aspects of Borrelia spp. in a protected urban area of Buenos Aires city, Argentina, where thousands of people visit this area for recreational purposes. Ticks were collected from vegetation, birds and dogs. Three hundred and forty birds belonging to 43 species, 41 genera, 18 families and six orders were captured (90.3% corresponded to the order Passeriformes). One hundred and twenty ticks were collected from 47 birds (13.8%) belonging to 10 species (23.2%), all of them from to the order Passeriformes (Emberizidae, Furnariidae, Parulidae, Thraupidae, Troglodytidae, Turdidae). Ticks were identified as Ixodes auritulus (56 larvae, 44 nymphs and 8 females) and Amblyomma aureolatum (1 larva and 11 nymphs). One thousand and ninety-one ticks collected from vegetation, 100 ticks collected from birds, and 89 ticks from dogs were tested for Borrelia infection by PCR trials targeting the flagellin (fla) and 16S rRNA genes. In addition, 101 blood and 168 tissue samples from birds were analyzed. Nine nymphs of A. aureolatum (2.1%) and four nymphs of I. auritulus (0.7%) collected from vegetation were positive. Five nymphs of A. aureolatum (45.4%), and five pools of larvae (minimum infection rate 13.5%), 18 nymphs (40.9%) and one female (14.3%) of I. auritulus collected on birds were also positive. The remaining samples were negative. The phylogenetic tree generated with fla sequences shows that seven of the eight different haplotypes of Borrelia detected in I. auritulus conform an independent lineage within the Borrelia burgdorferi sensu lato complex together with sequences of Borrelia sp. detected in I. auritulus from Canada and Uruguay. The fla sequences of Borrelia obtained from A. aureolatum and one sequence of a single specimen of I. auritulus conform a phylogenetic group with Borrelia turcica, Borrelia sp. isolated from a tortoise in Zambia, Borrelia spp. detected in Amblyomma maculatum from USA and Amblyomma longirostre from Brazil. The epidemiological risk that implies the infection with Borrelia genospecies associated with I. auritulus seems to be low because this tick is not aggressive to humans, but it helps to maintain borrelial spirochetes in the enzootic transmission cycles. The pathogenicity to humans of the Borrelia found in A. aureolatum is unknown; however, adults of this tick species are known to bite humans. This is the first report of the presence of Borrelia in A. aureolatum. Further investigations are necessary to know the risk of transmission of borreliosis by hard ticks in the study area.

Abstract
Microorganisms harbored by Chilean autochthonous ticks have been scarcely studied and current knowledge is restricted to three species of hard ticks only. The current study aimed to assess the presence of Anaplasmataceae, Borrelia and Hepatozoon agents in ticks collected directly from the environment, on reptiles, birds and mammals in twelve localities from northern, central and southern regions of the country and Antarctica. Ticks were identified by means of a morphological and molecular approach. PCR detections point the occurrence of an Anaplasma-like agent and a relapsing fever Borrelia sp. in Ornithodoros spheniscus; an Ehrlichia sp. and a Hepatozoon sp. in Ornithodoros atacamensis; "Candidatus Neoehrlichia chilensis", Borrelia burgdorferi sensu lato (s. l.), and Hepatozoon in Ixodes ticks morphologically related to the Ixodes sigelos group; and B. burgdorferi s. l. in Ixodes auritulus. Supported by phylogenetic analyses of characterized microorganisms, this study introduces putative vector roles and initial evidence on possible new agents detected in Chilean ticks.

Abstract
Companion vector-borne diseases (CVBDs) are an important threat for pet life, but may also have an impact on human health, due to their often zoonotic character. The importance and awareness of CVBDs continuously increased during the last years. However, information on their occurrence is often limited in several parts of the world, which are often especially affected. Latin America (LATAM), a region with large biodiversity, is one of these regions, where information on CVBDs for pet owners, veterinarians, medical doctors and health workers is often obsolete, limited or non-existent. In the present review, a comprehensive literature search for CVBDs in companion animals (dogs and cats) was performed for several countries in Central America (Belize, Caribbean Islands, Costa Rica, Cuba, Dominican Republic, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Puerto Rico) as well as in South America (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, French Guiana, Guyana (British Guyana), Paraguay, Peru, Suriname, Uruguay, Venezuela) regarding the occurrence of the following parasitic and bacterial diseases: babesiosis, heartworm disease, subcutaneous dirofilariosis, hepatozoonosis, leishmaniosis, trypanosomosis, anaplasmosis, bartonellosis, borreliosis, ehrlichiosis, mycoplasmosis and rickettsiosis. An overview on the specific diseases, followed by a short summary on their occurrence per country is given. Additionally, a tabular listing on positive or non-reported occurrence is presented. None of the countries is completely free from CVBDs. The data presented in the review confirm a wide distribution of the CVBDs in focus in LATAM. This wide occurrence and the fact that most of the CVBDs can have a quite severe clinical outcome and their diagnostic as well as therapeutic options in the region are often difficult to access and to afford, demands a strong call for the prevention of pathogen transmission by the use of ectoparasiticidal and anti-feeding products as well as by performing behavioural changes.

Abstract
Borrelia burgdorferi sensu lato (s. l.) spirochetes are associated with a wide range of vectors and hosts. Birds are important hosts in the ecology of some hard ticks (Ixodidae) in northwestern Argentina, where B. burgdorferi s.l. have been detected in Ixodes pararicinus. We evaluated Borrelia infection in ticks collected from wild birds by molecular analysis through the presence of Borrelia DNA (by nested-PCR targeting the fla gene). A total of 381 ticks (357 larvae and 24 nymphs) belonging to four species (I. pararicinus, Haemaphysalis juxtakochi, Haemaphysalis leporispalustris and Amblyomma sp.) were collected. Partial sequences of the fla gene of Borrelia (100% identical to Borrelia sp. haplotype I from Argentina) were detected in 9 of 70 tick pools (6 pools of larvae and 1 pool of nymphs of I. pararicinus, and in 2 pools of H. juxtakochi larvae) collected on Turdus rufiventris, Syndactila rufosuperciliata and Troglodytes aedon. The results of this study suggest that resident birds have reservoir capacity for Borrelia sp. haplotype I.

Abstract
This study was performed to determine the tick species that infest cattle and humans throughout an altitudinal gradient in the Yungas Biogeographic Province of Argentina. The presence of tick-borne bacteria of the genera Rickettsia, Ehrlichia and Borrelia in the collected ticks was also evaluated. Samples of ticks parasitizing cattle and humans were carried out in different seasons. Questing ticks (adults and nymphs) were collected from vegetation and analyzed to detect the presence of Rickettsia, Ehrlichia and Borrelia by a battery of different PCRs. Five species of hard ticks were found parasitizing cattle: Amblyomma sculptum, Amblyomma tonelliae, Amblyomma hadanii, Haemaphysalis juxtakochi and Ixodes pararicinus. Amblyomma sculptum (immature and adults), A. tonelliae (immature and adults), A. hadanii (larvae) and one nymph of I. pararicinus were found attached to humans. Rickettsia amblyommatis was detected in one nymph of A. hadanii. DNA of a Borrelia genospecies belonging to the B. burgdorferi s.l. complex (phylogenetically related to haplotypes previously reported in Ixodes aragaoi from Uruguay and I. pararicinus from Argentina) was detected in adults of I. pararicinus. Amblyomma sculptum and I. pararicinus appear to be the tick species more frequent on cattle in the YBP from Argentina, and A. sculptum and A. tonelliae, were the main ticks found attached to humans. The medical importance of the bacteria of the genus Rickettsia and Borrelia detected in this work remains unknown.

Abstract
Lyme borreliosis is a vector-borne zoonosis caused by Borrelia burgdorferi sensu lato species complex spirochetes, which are maintained in transmission cycles among vertebrates and Ixodes ticks. Recently, a new genospecies within this complex, Borrelia chilensis, was described in Ixodes stilesi collected from the environment and from rodents in Chile. This tick also infests the native Southern pudu deer (Pudu puda). The objectives of this study were to investigate the prevalence, intensity of infestation, and aggregation of hard ticks on this deer species, and to determine the presence of borrelial pathogens in the ticks. Sixty-six deer were examined over a two-year period. A total of 179 ticks of two species, I. stilesi and Ixodes taglei, were collected. Of those, 100 were adults, 78 were nymphs, and one was a larva. Ixodes stilesi was the most prevalent tick (47%) and was highly aggregated (D=0.77) on the deer. Deer body weight was positively associated with tick burden. Borrelia spirochetes were detected in two (6.45%) of the examined I. stilesi ticks. Phylogenetic analyses of 16S and flaB gene sequences positioned these samples in the same clade with Borrelia chilensis VA1 previously described from Chile. These findings suggest that I. stilesi may play a role in the local persistence of B. chilensis. Further studies are required to fully understand the mechanisms of natural transmission of B. chilensis and the risk of infection in humans.

Abstract
This work was performed to evaluate the presence of Borrelia in different populations of Ixodes pararicinus from northwestern Argentina (Jujuy, Salta and Tucumán provinces). Questing adults and nymphs of I. pararicinus were collected from vegetation, and I. pararicinus nymphs were also collected on birds. Eighty-two ticks were tested for Borrelia presence by PCR targeting the gene flagellin and the rrfA-rrlB intergenic spacer region. Pools of ticks positive to Borrelia were formed by two nymphs collected on Turdus rufiventris in Tucumán, one nymph collected on Syndactyla rufosuperciliata in Jujuy, one nymph collected on Turdus nigriceps in Tucumán, three nymphs collected on T. nigriceps in Tucumán, and two females collected from vegetation in Salta. Two haplotypes of Borrelia sp. belonging to the Borrelia burgdorferi sensu lato complex were found. One of them is closely related to the haplotypes of Borrelia genospecies previously reported in I. aragaoi from Uruguay (haplotypes D and E) and in I. pararicinus from Jujuy Province in Argentina. The second haplotype (detected in the sample of Salta) is closely related to the haplotypes A, B and C associated with I. aragaoi from Uruguay. All these results suggest that the presence of B. burgdorferi s.l. genospecies in I. pararicinus ticks is widespread along the entire distribution of this tick species in northwestern Argentina. However, the Borrelia presence in I. pararicinus cannot be directly assumed as a phenomenon of medical relevance, because Ixodes ticks are not relevant as human parasites in South America, and none of the two Borrelia genospecies detected in this work is related to any of the Borrelia genospecies currently known to be pathogenic to humans.

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
Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosis likely involves capybaras as reservoirs and Amblyomma and Rhipicephalus ticks as vectors. Thus, domestic animals can serve as key carriers in pathogen dissemination. This zoonosis has been little studied in horses in Brazil. The first survey was performed in the state of Rio de Janeiro, and this Brazilian Borreliosis exhibits many differences from the disease widely described in the Northern Hemisphere. The etiological agent shows different morphological and genetic characteristics, the disease has a higher recurrence rate after treatment with antibiotics, and the pathogen stimulates intense symptoms such as a broader immune response in humans. Additionally, the Brazilian zoonosis is not transmitted by the Ixodes ricinus complex. With respect to clinical manifestations, Baggio-Yoshinari Syndrome has been reported to cause neurological, cardiac, ophthalmic, muscle, and joint alterations in humans. These symptoms can possibly occur in horses. Here, we present a current panel of studies involving the disease in humans and equines, particularly in Brazil.

Borrelia burgdorferi sensu lato in Ixodes cf. neuquenensis and Ixodes sigelos ticks from the Patagonian region of Argentina. Acta Trop 2016; 162:218-221. [PMID: 27372197 DOI: 10.1016/j.actatropica.2016.06.030] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2016] [Revised: 06/22/2016] [Accepted: 06/25/2016] [Indexed: 11/23/2022]
Abstract
This study was conducted to detect Borrelia burgdorferi sensu lato infection in ixodid ticks from the Patagonia region in the south of Argentina. Therefore, ticks were collected on rodents in the provinces of Chubut, Río Negro and Santa Cruz. These ticks were identified as nymphs of Ixodes cf. neuquenensis and Ixodes sigelos. The B. burgdorferi s.l. infection was tested by a battery of PCR methods targeting the gene flagellin (fla) and the rrfA-rrlB intergenic spacer region (IGS). Three pools of I. sigelos nymphs from Chubut and Santa Cruz provinces as well as one pool of I. cf. neuquenensis nymphs from Río Negro province were tested positive in the fla-PCR. The samples of I. sigelos were also positive for the IGS-PCR. Phylogenetically, the haplotypes found in the positive ticks belong to the B. burgdorferi s.l. complex, and they were closely related to Borrelia chilensis, a genospecies isolated from Ixodes stilesi in Chile. The pathogenic relevance of the Borrelia genospecies detected in both I. neuquenensis and I. sigelos is unknown.

Nested coevolutionary networks shape the ecological relationships of ticks, hosts, and the Lyme disease bacteria of the Borrelia burgdorferi (s.l.) complex. Parasit Vectors 2016; 9:517. [PMID: 27662832 PMCID: PMC5035442 DOI: 10.1186/s13071-016-1803-z] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2016] [Accepted: 09/14/2016] [Indexed: 12/12/2022] Open
Abstract
Background The bacteria of the Borrelia burgdorferi (s.l.) (BBG) complex constitute a group of tick-transmitted pathogens that are linked to many vertebrate and tick species. The ecological relationships between the pathogens, the ticks and the vertebrate carriers have not been analysed. The aim of this study was to quantitatively analyse these interactions by creating a network based on a large dataset of associations. Specifically, we examined the relative positions of partners in the network, the phylogenetic diversity of the tick’s hosts and its impact on BBG circulation. The secondary aim was to evaluate the segregation of BBG strains in different vectors and reservoirs. Results BBG circulates through a nested recursive network of ticks and vertebrates that delineate closed clusters. Each cluster contains generalist ticks with high values of centrality as well as specialist ticks that originate nested sub-networks and that link secondary vertebrates to the cluster. These results highlighted the importance of host phylogenetic diversity for ticks in the circulation of BBG, as this diversity was correlated with high centrality values for the ticks. The ticks and BBG species in each cluster were not significantly associated with specific branches of the phylogeny of host genera (R2 = 0.156, P = 0.784 for BBG; R2 = 0.299, P = 0.699 for ticks). A few host genera had higher centrality values and thus higher importance for BBG circulation. However, the combined contribution of hosts with low centrality values could maintain active BBG foci. The results suggested that ticks do not share strains of BBG, which were highly segregated among sympatric species of ticks. Conclusions We conclude that BBG circulation is supported by a highly redundant network. This network includes ticks with high centrality values and high host phylogenetic diversity as well as ticks with low centrality values. This promotes ecological sub-networks and reflects the high resilience of BBG circulation. The functional redundancy in BBG circulation reduces disturbances due to the removal of vertebrates as it allows ticks to fill other biotic niches.
