“…was observed, 59, together with a diversity of eight species of Eimeria . in South Africa, Fatoba et al ( 25 ) observed that 46.3% of the farms were positive for coccidian infections. In a similar study carried out in Tunisia by Kaboudi et al ( 6 ), a prevalence of 31.8% was observed for coccidia of the genus Eimeria spp., and the species E. maxima, E. tenella and E. acervulina were characterized through their morphology.…”

“…According to Flores et al ( 31 ), the high prevalence and diversity, associated with indiscriminate use of anticoccidials are responsible for severe drug resistant Eimeria species in Korean chicken farms. Mixed infection, according to Fatoba et al ( 25 ), is very common: it causes increased pathogenicity and is a threat to vaccine control. This information also demonstrates the failure of zootechnical control and the low quality of animal management, in which the animals lost weight.…”

In tropical regions, family farming is a form of production and work that is highly present in rural areas. Because the production system for free-range chickens has a low level of technification, it frequently presents massive infection by coccidia. The objective of this study was to determine the prevalence and diversity of Eimeria species in free-range chickens in northeastern Brazil. Fecal analyses were carried out using materials collected from 100 farms, belonging to 10 different municipalities. The sample from each farm was composed of five stool samples collected from different animals. Coproparasitological analyses were performed and, in each positive sample, photomicrographs of 20 oocysts were used for morphological identification of coccidia. The presence of Eimeria spp. was detected in 59% (59/100) of the farms analyzed. Species identification was performed through morphometric analysis of 1,180 sporulated oocysts. The following eight species of Eimeria spp. were found, in decreasing order of prevalence: Eimeria necatrix (25%), Eimeria mitis (18.3%), Eimeria mivati (17.3%), Eimeria tenella (12.4%), Eimeria brunetti (9.9%), Eimeria acervulina (9.1%), Eimeria praecox (4.8%) and Eimeria maxima (3.2%). The prevalence and diversity of Eimeria spp. on farms producing backyard chickens in the semiarid region of Brazil were high, especially the diversity of species. Changing the management, with the adoption of sanitary measures, may be effective in reducing the high prevalence of coccidia on the farms studied.

“…No que diz respeito a análise parasitológica para pesquisa de Eimeria spp., do total de 124 amostras de intestino de frangos caipiras, 92 (74,19%) tiveram a presença do agente (Tabela 1), com contagens que variaram de 100 a 18.800 oocistos por amostra. Os resultados indicam a alta ocorrência de aves infectadas por Eimeria spp., sendo considerados superiores aos estudos de ocorrência de oocistos do parasita em frangos caipiras nas cidades de Porto Alegre, RS, no Brasil (55,4%; Siqueira e Marques, 2016), Shidi Tab, na Tunísia (31,8%; Kaboudi et al, 2016) e província de KwaZulu-Natal, África do Sul (59,5%; Fatoba et al, 2020).…”

“…Apesar da alta ocorrência de oocistos de Eimeira spp. em amostras de intestinos de frangos caipiras, as manifestações clínicas foram ausentes (Gráfico 1), corroborando de que a coccidiose subclínica é predominante em aves de sistemas caipiras (Kaboudi et al, 2016;Fatoba et al, 2020). O grau de severidade da coccidiose depende da carga parasitária, da capacidade imunológica, idade do hospedeiro e patogenicidade do parasita, relacionado principalmente a espécie de Eimeira (Quiroz-Castañeda e Dantán-González, 2015).…”

A avicultura de frango tipo caipira difundiu-se de forma ampla em todo país. Apesar das características de rusticidade, essas aves são suscetíveis a doenças graves como as salmoneloses e a coccidiose aviária. Objetivou-se pesquisar os agentes infecciosos dessas doenças em frangos caipiras destinados a alimentação escolar no município de São Luís, MA. Procedeu-se o exame clínico de 198 aves, que consistiu na observação da aparência da plumagem, bico, cristas, região da cloaca e condição corporal. As amostras foram analisadas para pesquisa de Salmonella spp. seguindo a metodologia do Ministério da Agricultura, Pecuária e Abastecimento. Das 99 amostras de cloaca (pool de duas aves), coletadas para pesquisa de Salmonella spp., 10 (10,1%) amostras foram suspeitas para a bactéria nas provas bioquímicas, porém todas foram negativas (0%) por sorotipificação antigênica. Na pesquisa e contagem de oocistos de Eimeria spp. foi utilizado o método de centrífugo–flutuação em solução de sacarose. Na contagem de oocistos de Eimeria spp., das 124 amostras coletadas de intestino durante a evisceração, 92 (74,19%) amostras apresentaram oocistos do parasita, com contagens variando de 100 a 18.800 oocistos. Os resultados foram considerados esperados visto que em sistema de criação de frangos caipiras, onde não se utiliza drogas cocciostáticas, a prevalência de Eimeria spp. é frequentemente elevada. Portanto, pode-se concluir que os frangos de corte tipo caipira destinados ao abatedouro no município de São Luís não apresentaram isolamento para Salmonella spp., porém tiveram alta ocorrência de infecção por oocisto de Eimeria spp.

“…Infections with several Eimeria species are very common on farms [42,43]. Gyorke et al (2013) describe that in our neighbouring country, Romania, there are mixed infections, usually with two, three or four different types of Eimeria [22].…”

Coccidiosis is a significant poultry disease caused by the Eimeria species. This study aims to determine the prevalence of Eimeria spp. on broiler farms in Vojvodina, along with the identification of parasite species, and assess the implemented biosecurity measures. The study was conducted on 100 broiler chicken farms (28 small-sized; 34 medium-sized; 38 large-sized farms) from June 2018 to December 2021. One pooled sample of faeces was collected from three to six-week-old chickens from each farm, and assessment of biosecurity measures was carried out using a questionnaire. Using the PCR method, DNA of Eimeria was found in 59 samples (59%), while 41 samples (41%) were negative. Four species of Eimeria were identified, and their prevalence was the following: E. acervulina (37%), E. maxima (17%), E. mitis (25%) and E. tenella (48%). A significant difference (p < 0.05) was established in the number of oocysts in flocks from small-sized farms compared to medium-sized farms. It was found that regular implementation of disinfection, disinsection and deratisation measures, as well as all the biosecurity measures, can significantly reduce the occurrence of coccidiosis. These results will help to develop better strategies for the control and prevention of coccidiosis on farms.
