Abstract
This study focuses on the occurrence, identification, and molecular characterization of Eimeria species causing coccidiosis in cattle in the Kashmir Valley, India. Coccidiosis, caused by apicomplexan parasites of the genus Eimeria, poses a significant threat to global cattle farming. Conventional techniques for identification, which rely on the morphology of sporulated oocysts, have drawbacks, leading to the adoption of molecular techniques to accurately delimit species. A total of 190 cattle were sampled in nine farms and parasitological examination revealed an occurrence of 45.7% for Eimeria spp. Molecular analysis using PCR and sequencing identified three predominant species: E. zuernii, E. alabamensis, and E. bovis. The study highlights the widespread occurrence of these species globally, as supported by previous research conducted in Bangladesh, Austria, Egypt, and Brazil. The phylogenetic analysis based on internal transcribed spacer (ITS-1) gene sequences revealed distinct clusters for E. zuernii and E. bovis, while E. alabamensis formed a separate clade. The genetic diversity and phylogenetic connections provide insights into the evolutionary relationships among these Eimeria species. This study contributes valuable information for understanding the epidemiology and genetic diversity of cattle coccidiosis in the Kashmir Valley, emphasizing the importance of molecular characterization for accurate species identification.

[PMID: 36110350 PMCID: PMC9470120 DOI: 10.2147/vmrr.s377017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 08/10/2022] [Indexed: 11/23/2022]
Abstract
Introduction Eimeria infection is one of the protozoal diseases of animals caused by various species of Eimeria (intracellular parasite) and causes reduced productivity and mortality in ruminants, especially in young ones. Despite the fact that the disease is one of the leading causes of economic losses, there is little information in Ethiopia on the occurrence of the infection in cattle and sheep. Methods A cross-sectional study was conducted from December 2021 to April 2022 in and around Adama and Bishoftu towns with the objectives to estimate the prevalence of Eimeria infection; identify circulating Eimeria oocysts, the intensity/burden of infection and associated risk factors of Eimeria infection in cattle and sheep. A total of 384 randomly selected (265 cattle and 119 sheep) fecal samples were collected from the rectum and examined by flotation technique using sheather’s sugar solution to detect the oocysts of Eimeria. A 2.5% potassium dichromate solution was added to the positive fecal samples for sporulation of the oocysts. Results and discussion The overall prevalence of 48.95% Eimeria infection was recorded during the study. 45.0% and 58% prevalence of the infection was registered in cattle and sheep, respectively. There was a statistically significant difference (P ˂ 0.05) in Eimeria infection between the study animal species, age of the animals, breed, farm hygiene and management system. However, there was no significant difference in Eimeria infection (P > 0.05) in sex, body condition of the animals and fecal consistency. The maximum oocysts per gram of feces was found to be 10,000. Eimeria infection is of great importance to livestock producers and requires serious control and prevention initiatives.

Abstract
The objectives of the present study were: (1) to determine the prevalence of Eimeria spp. sporulated oocysts in calves from 26 Municipalities in the Central Zone of the State of Veracruz, Mexico, (2) to identify the Eimeria spp. infecting calves, and (3) to identify the risk factors associated with the presence of Eimeria spp. in tropical cattle. A total of 930 individual fecal samples were analyzed by using the McMaster technique; then, oocysts were maintained in 2.5% potassium dichromate to allow sporulation. The general prevalence of calves with Eimeria spp. oocysts was 39.7% (370/930). Of a total of 10 identified species, Eimeria canadensis was the most observed, followed by Eimeria bovis and Eimeria zuernii. The statistical analysis showed an association between the age of the calves (5 to 9 months), the presence of other animals, the physiographic regions and the restricted type of husbandry with the presence of Eimeria spp. in calves (P<0.05). Protective risk factors, such as: routine coprological analysis was also associated with a decrease in infection. These data demonstrate the presence of coccidia in cattle from the State of Veracruz, additionally to the necessary measures that must be taken to control this parasitosis.

Abstract
A cross-sectional study was conducted to investigate coccidian infection and associated factors in smallholder pigs, and to identify Cystoisospora oocysts by PCR. A total of 500 pig faecal samples from 330 smallholder farms were collected in Nay Pyi Taw, Myanmar. The faecal flotation method was used to identify Eimeria and Cystoisospora species, and oocyst counts per gram (OPG) of faeces were recorded. Oocysts were differentiated after sporulation. Oocyst DNA was subjected to ITS1-targeted Cystoisospora-specific PCR. The overall coccidian oocyst detection rate by microscopic was 89.0% (445/500). Among the studied samples, 74.0% (370/500) and 70.6% (353/500), were found to be positive with Eimeria spp. and Cystoisospora suis oocysts, respectively. The sequences of C. suis detected were 100% identical to those of C. suis reported from Japan, and had 99.5% resemblance to sequences from Australia and China. Weaner pigs showed the significantly highest (p < 0.05) OPG when compared to other age groups. The highest intensity of coccidian infection (p < 0.05) was found in pigs fed local feed, pigs raised on earthen floors and pigs under poor hygienic conditions. Factors such as age, breed, feed type, and housing floors were found to be significantly associated with coccidian infection (p < 0.05). Age, as well as management factors including floor type, feed type, and hygiene practices on the farm, had a strong influence on the occurrence of coccidian infection in pigs. This is the first study in Myanmar on coccidian infection in pigs and molecular detection of C. suis.

Abstract
Eimeria species have importance to calves because of the economic losses. The aim of this study was to identify the species of Eimeria that affect calves and the risk factors associated with its natural infection. Fecal samples (387) were collected from dairy farms in the southern Agreste of Pernambuco. The feces were evaluated using the Gordon & Whitlock technique and were cultured in 2.5% potassium dichromate for sporulation of oocysts. Odds ratio (OR) were calculated to assess risk factors. Eimeria spp. were detected in 50.65% (196/387) of the samples. Eleven species were identified, being Eimeria bovis (26.64%; 548/2057), Eimeria zuernii (19.69%; 405/2057) and Eimeria ellipsoidalis (14.49%; 298/2057) those more frequent. Small herds (OR = 1.93), calves aged up to six months (OR = 2.12), absence of manure pit (OR = 7.52), fortnightly cleaning (OR = 4.71), collective calf pens (OR = 3.26), manual milking (OR = 2.16) and absence of veterinary care (OR = 2.28) were considered to be risk factors. The data revealed pathogenic species in more than 50% of the farms. Thus, the importance of adopting sanitary measures to reduce the spread of these protozoa in herds should be done, because of economic losses associated with its infection.

Abstract
Eimeria spp. cause the disease coccidiosis, which results in chronic wasting of livestock and can lead to the death of the animal. The disease, common worldwide, has caused huge economic losses to the cattle industry in particular. This is the first systematic review and meta-analysis of the prevalence of bovine Eimeria in China. Our search of five databases including PubMed, ScienceDirect, China National Knowledge Infrastructure (CNKI), Chongqing VIP, and Wan Fang for articles published up to February 29, 2020 on the prevalence of Eimeria in cattle in mainland China yielded 46 articles, in which the prevalence of cattle ranged from 4.6% to 87.5%. The rate of bovine Eimeria infection has been decreasing year by year, from 57.9% before 2000 to 25.0% after 2015, but it is still high. We also analyzed the region, sampling years, detection methods, feeding model, seasons, and species of bovine Eimeria. We recommend that prevention strategies should focus on strengthening detection of Eimeria in calves in the intensive farming model.

Abstract
A large-scale cross-sectional epidemiological study was conducted to evaluate prevalence, species diversity, and associated risk factors of Eimeria infections in 55 cattle farms across seven states of Colombia, including subtropical and tropical regions. In total, 1333 fecal samples from young animals (< 1 year of age) were examined at a single sampling date from August 2016 to December 2016. Flotation and McMaster techniques were conducted for parasitological investigation. Excreted Eimeria oocysts were allowed to sporulate in vitro and thereafter identified to species level based on morphological and morphometric characteristics. The overall Eimeria prevalence was 75.5% (1006/1333), with no difference observed between age categories. In total, 13 different Eimeria species were identified. The most prevalent species was E. bovis (33.5%), followed by E. auburnensis (12.5%) and E. zuernii (11.9%). Analysis of extrinsic associated risk factors revealed the floor type, feeding system, watering system, and herd size as significant (p < 0.05) risk factors for Eimeria spp. infections. Based on these data, it can be assumed that bovine coccidiosis infections occur ubiquitously in the country and might play an important role especially in its subclinical form by affecting production parameters in conventional cattle management systems.

Abstract
Abstract This study aimed to identify the frequency of occurrence of Eimeria species in Holstein (taurine dairy cattle) and Nelore (zebu beef cattle) on 12 farms in the state of Goiás, Brazil. A total of 2,601 animals were evaluated, and the cattle were divided into the following age-group categories: up to three months old, four to eight months old, nine to 16 months old and cows. Fecal samples were collected directly from the rectum of all animals. None of the cattle presented any clinical signs of eimeriosis during the survey. From the results obtained, it could be concluded that higher rates of infection by Eimeria spp. were observed in Holstein cattle between the 1st and 16 th months of age and in Nelore cattle between the 1st and 8th months of age. Twelve and nine Eimeria species were diagnosed in Holstein and Nelore cattle, respectively. However, Eimeria zuernii was more prevalent in animals up to three months old, while Eimeria bovis was more common in the remaining categories (cattle aged four months and over). Future studies on the epidemiology and/or seasonality of infection by Eimeria species in cattle, from birth onwards, are needed in order to better understand the dynamics of E. zuernii and E. bovis occurrences, especially in cattle under three months of age.

Abstract
In the Experimental Farm of the Universidade Federal de Lavras (EF-UFLA), state of Minas Gerais, Brazil, on their day of birth, female Holstein calves were randomly selected and placed into two groups containing fifteen animals each: Strategic-Selective Treatment (S-ST) or Conventional Treatment (CT). In the S-ST, calves were treated after coproparasitological examinations according to criteria established previously by the researchers. Calves in the CT were treated according to the opinion of the veterinarian of EF-UFLA. For statistical analysis, the frequency (%) of fecal samples with count of eggs per gram of feces (EPG) ≥300, count of oocysts per gram of feces (OoPG) ≥500 and fecal samples with count of cysts of Giardia spp. ≥1 were conducted. The overall average frequency of fecal samples with EPG ≥300, OoPG ≥500 and Giardia spp. cysts ≥1, respectively, was similar (p >0.05) between S-ST (20.3%; 17.3%; and 31.5%) and CT (26.4%; 23.9%; and 37.3%). The effective operational cost, per animal, in 12 months, was of R$ 784.58 (US$ 241.41) and R$ 83.90 (US$ 25.81) in S-ST and CT, respectively. The S-ST requires adjustments to be used as a technically efficient and economically viable alternative for the control of gastrointestinal parasitosis in female Holstein calves.

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
RESUMO: O presente trabalho tem como objetivo relatar surtos consecutivos (Agosto de 2015 e 2016) ocasionado por Eimeria zuernii em bezerros de corte, Canchim e Nelore, com aproximadamente 45 dias de vida, em uma propriedade rural localizada no município de São João da Boa Vista, estado de São Paulo. O primeiro surto foi diagnosticado em um lote composto por 78 bezerros, entre 35 e 55 dias de idade. Dos 78 bezerros, 32 eram Nelore e os outros 46 Canchim. Já o segundo, ocorreu em um novo lote de 66 bezerros (sendo 36 Nelore e 47 Canchim), com idade entre 30 e 45 dias. Alguns animais apresentaram diarreia sanguinolenta e desidratação. Colheitas de fezes de todos os animais (vacas e bezerros) foram realizadas para realização de exame coproparasitológico e quantificação de ovos e oocistos por grama (OPG e OoPG) de fezes de parasitos. Com base nos resultados encontrados neste estudo, é possível afirmar que os surtos consecutivos em bezerros de corte entre 30 e 55 dias de idade, na época seca do ano (agosto), foram desencadeados pelo elevado grau de infecção destes animais por E. zuernii. Analisando os dois anos em que os surtos ocorreram, a presença de sinais clínicos (diarreia sanguinolenta) e a mortalidade de bezerros desencadeada pela eimeriose/desidratação, aconteceram em 8,3% 1,4% do rebanho, respectivamente. Estes resultados destacam a importância em se realizar pesquisas de campo, com o objetivo de se melhor entender a dinâmica de parasitismo de E. zuernii e E. bovis em bezerros com idade inferior a três meses, em função dos motivos já discutidos neste estudo. Além disso, é necessário que se investigue as possíveis fontes de infecção, como a água ingerida pelos animais, para que condutas práticas possam ser adotadas/recomendadas aos proprietários, diminuindo desta maneira os prejuízos ocasionados por surtos de Eimeria spp em rebanhos bovinos.

Abstract
RESUMO: A principal importância da eimeriose em bovinos, se deve ao baixo desempenho produtivo que os animais demonstram quando esta enfermidade apresenta-se sob a forma sub-clínica. Como objetivos, o presente trabalho avaliou a eficácia do uso da lasalocida sódica contra espécies de Eimeria spp. parasitando bezerros; avaliou também o desempenho ponderal dos animais submetidos aos diferentes tratamentos e analisou alguns fatores epidemiológicos que possam interferir na infecção por Eimeria nos bezerros. Foram utilizados 288 bezerros no dia 0 do estudo. Os animais pertencentes ao tratamento 01 receberam sal mineral proteinado de baixo consumo sem adição de lasalocida, enquanto que os bezerros do Tratamento 02 sal mineral proteinado de baixo consumo, com adição de lasalocida sódica, administrado via oral para bezerros dos quatro/cinco/seis meses até dez meses de idade. Colheita de fezes e pesagem dos animais foram realizadas nos dias 0 (antes do início do experimento), na desmama, 30 e 60 dias após desmama (DPD). A avaliação de alguns fatores epidemiológicos que pudessem ser relacionados com a infecção por Eimeria spp nos bezerros, como o desmame, sexo e época do ano, foram analisados neste estudo, levando-se em consideração os resultados encontrados durante todo estudo, para os 144 animais pertencentes ao grupo controle. Foram identificadas nove espécies de Eimeria nos bezerros em ordem decrescente: E. brasiliensis, E. wyomingensis, E. bovis, E. canadenses, E. zuernii, E. auburnensis, E. ellipsoidalis, E. pellita e E. cylindrica. Inesperadamente, diminuição na carga parasitária dos animais pode ser observada após o desmame. Mesmo a fazenda não adotando medidas de manejo que visam maior produtividade como a Inseminação Artificial em Tempo Fixo, que por sua vez acaba aumentando o número de nascimentos e unidade animal/hectare em uma determinada época do ano, elevado parasitismo pelo coccídio em questão foi diagnosticado nos bezerros pertencentes ao grupo controle. Talvez a época do ano em que o estudo foi realizado pode ter influenciado neste aspecto. As contagens de oocistos por grama (OoPG) de fezes para Eimeria dos animais tratados com lasalocida foram estatisticamente inferiores (P≤ 0,05) as do grupo controle após o início do estudo. O composto alcançou eficácia ≥ 95% contra o parasito em questão. No final do estudo, os animais que receberam lasalocida ganharam em média, 7,2kg a mais (P≤ 0,05) que os bezerros pertencentes ao grupo controle. Em propriedades que tem como objetivo a venda de bezerros logo após a desmama, recomenda-se o início do tratamento com a lasalocida, junto ao creep-feeding, a partir de três messes de idade, uma vez que diferencial no ganho em peso médio dos bezerros tratados foi significativamente (P≤ 0,05) mais elevado, em comparação ao grupo controle, após cinco meses de tratamento com o referido composto. Apesar de a lasalocida ser utilizada como um aditivo alimentar para animais, a diferença no ganho em peso vivo médio entre animais tratados com a lasalocida, em comparação a animais pertencentes ao grupo controle, também pode ser relacionada, em partes, a infecção dos animais por Eimeria spp., conforme discutido neste artigo, entretanto, futuros estudos devem ser conduzidos para comprovar esta hipótese.

Abstract
Resumo A ocorrência de eimeriose foi pesquisada em 110 bezerros da raça holandesa pertencentes a dez propriedades de agricultura familiar. As amostras de fezes foram coletadas via retal e analisadas por métodos parasitológicos qualitativos e quantitativos. Amostras de fezes positivas para Eimeria sp. foram submetidas à esporulação in vitro para posterior identificação microscópica da espécie. Todas as propriedades apresentaram positividade enteroparasitária por espécies do gênero Eimeria havendo uma prevalência de 48,2% dos animais parasitados. Foram identificadas oito espécies do gênero Eimeria, sendo E. Bovis, E. auburnensis e E. alabamensis as mais frequentes, com 23,6%, 11,8% e 9,1%, respectivamente. Animais com até seis meses de idade manejados de forma coletiva e a pasto apresentaram maior positividade enteroparasitária. A elevada prevalência de infecção parasitária em animais jovens, principalmente por coccidios de considerável patogenicidade, é indicador de falhas no manejo sanitário, sendo necessário criterioso monitoramento com uso de fármacos específicos para controlar infecções e reduzir perdas zootécnicas.

Abstract
Aim: To determine the prevalence and diversity of Eimeria spp. in dairy cattle present in and around Guwahati, Kamrup district, Assam, India. Materials and Methods: A total of 2339 fecal samples of calves (535), heifer (641) and adult (1163) cattle were screened for 1 year present in and around Guwahati, Assam for detection of Eimeria oocysts by flotation techniques. Sporulation of the oocyst was done in 2.5% potassium dichromate solution for identification of the Eimeria species. Results: Examination of fecal samples revealed an overall prevalence of 11.97% Eimeria infection in dairy cattle of Guwahati, Assam. Age-wise, 33.2%, 45.4%, and 21.4% infections were recorded in calves (<1 year), heifer (1-3 years) and adult (>3 years) cattle, respectively. Season-wise, infection was recorded highest during post-monsoon (16.29%), followed by monsoon (15%), winter (9.44%), and pre-monsoon (7.49%) season. Seven species of Eimeria were recorded viz. Eimeria bovis, Eimeria zuernii, Eimeria subspherica, Eimeria bukidnonensis, Eimeria auburnensis, Eimeria ellipsoidalis and Eimeria alabamensis. The oocyst count per gram of feces ranged from 50 to 1500 in infected cattle. Conclusion: This study indicates that there is the prevalence of seven species of Eimeria in dairy cattle of Guwahati, Assam and mostly prevalent during the post-monsoon season.

Abstract
OBJECTIVE To evaluate the presence of gastrointestinal parasites on cattle in Indonesia because the prevalence of parasites varies between countries depending on the terrain surrounding livestock farms and investigations in Indonesia have never been performed. METHODS Fecal samples from cattle at 35 farms in 7 districts in West Java, Indonesia, has been examined using the floatation or sedimentation methods, and a immunofluorescence assay and experimentally inoculation to mice for Cryptosporidium or Giardia.spp. RESULTS 153 of 394 examined cattle (38.8%) were infected with gastrointestinal parasites. The prevalence of Eimeria spp., Nematoda spp. (including Oesophagustomum and Bunostomum-like), Fasciola gigantica and Paramphistomum spp. was 22.4%, 11.2%, 12.5% and 3.8%, respectively. Cryptosporidium andersoni (C. andersoni) was also found in two samples. One isolate of this parasite was confirmed to be transmitted to mice, in contrast to the isolates from other countries. CONCLUSIONS although this survey is preliminary, the results shows that the infection of gastrointestinal parasites in Indonesia was not high, but these infected cattle could be as a potential source leading to economic losses in livestock production.

Abstract
The aim of this cross-sectional observational study was to determine the frequency and factors associated with infection by Eimeria spp. and gastrointestinal nematodes in 356 calves on 20 dairy farms located in southern Minas Gerais, Brazil. Ten species of Eimeria spp. were identified, of which E. bovis (37.6%) and E. zuernii (17.9%) were the most frequent. From fecal cultures, four genera of gastrointestinal nematodes were recovered, of which Cooperia spp. (74.6%) and Haemonchus (19.4%) were the most frequent. Variables relating to higher levels of technology used on dairy farms showed a significant association (p < 0.05) with higher OPG and EPG counts, and are discussed in this study.

Abstract
The frequency of species of the genus Eimeria in a dairy herd in the municipality of Boa Esperança, Southern region of the State of Minas Gerais was assessed. From 37 females of the Friesian breed aged three to seven months, 259 feces samples were analyzed between May and September 2008. The examinations to quantify oocysts per gram of feces (OPG) and identify Eimeria species were conducted at the Veterinary Parasitology Laboratory of the Federal University of Lavras. Eleven species of Eimeria were identified, namely: E. bovis (23.2%), E. zuernii (22.6%), E. ellipsoidalis (20.3%), E. cylindrica (14.1%), E. subspherica (5.4%), E. canadensis (3.5%), E. alabamensis (2.4%), E. auburnensis (2.4%), E. pellita (2.1%), E. brasiliensis (2%) and E. bukidnonensis (1.9%). E. bovis, E. zuernii and E. ellipsoidalis were the most frequent and the ones with the highest oocyst shedding over time (p < 0.05). Differences in OPG counts were found between most months studied (p < 0.05). The large number of Eimeria species found, in particular E. bovis and E. zuernii, indicates that Eimeria sp. has significant pathogenic potential in dairy cattle in the South of Minas Gerais.
