Resumo: Bovine neosporosis is a parasitic disease caused by the protozoan Neospora caninum. The parasite has a worldwide distribution and mainly affects the dairy cattle herd, although, reported in beef cattle, being described as one of the main causes of abortion in cattle. It is of great relevance in cattle breeding, since the presence of the etiological agent is associated with bovine abortion worldwide, thus promoting direct and indirect economic losses. It can cause early embryonic death, fetal abortion or mummification, stillbirths and neonates with neurological symptomatology. This study was carried out in the Dairy Cattle Facility of the UFRRJ, located in the city of Serop?dica-RJ, where blood samples were collected from 40 dairy cows in reproductive age from cranial superfial epigastric vein, and the tested by indirect immunofluorescence (RIFI) for detection of anti-N.caninum antibodies. The serology was performed at the Laborat?rio de Coccidios e Coccidioses (LCC) of UFRRJ. From the serological results, we verified the association or not with the manifestation of reproductive disorders, analyzed through the collection of data from the records of reproductive history from 2017 to 2018 and observations of the herd in the course of the study. The Chi-square test was used as a statistical model to verify the existence of an association between serology and reproductive disorders, adopting a confidence level of 95%. The results of the study show a seroprevalence in the herd of 27% (11/40) for N. caninum, however, after statistical analysis, the association between seropositivity and reproductive disturbances in the evaluated herd was not confirmed. Although the studied population is infected with N. caninum, we can infer that N. caninum antibodies present in Giroland dairy cows of the dairy cattle sector of the UFRRJ are not associated with the occurrence of reproductive disorders

O parasito possui distribui??o mundial e acomete sobretudo o rebanho bovino leiteiro, por?m, ? relatado tamb?m em rebanhos bovinos de corte, sendo descrito como uma das principais causas de aborto na esp?cie. ? de grande relev?ncia na bovinocultura, uma vez que a presen?a do agente etiol?gico est? associada a quadros de abortamento bovino no mundo, promovendo assim perdas econ?micas diretas e indiretas. Pode ocasionar morte embrion?ria precoce, abortamento ou mumifica??o fetal, natimortos e neonatos com sintomatologia neurol?gica. Este estudo foi desenvolvido no Setor de Bovinocultura de Leite da UFRRJ, localizado no munic?pio de Serop?dica-RJ, onde foram coletadas amostras de sangue de 40 vacas leiteiras em fase reprodutiva, da veia epig?strica superficial cranial, sendo as amostras testadas pela t?cnica de imunofluoresc?ncia indireta (RIFI) para detec??o de anticorpos anti-N. caninum. A sorologia foi realizada no Laborat?rio de Cocc?dios e Coccidioses (LCC) da UFRRJ. A partir dos resultados sorol?gicos, foi realizada a verifica??o de associa??o, ou n?o, com a manifesta??o de dist?rbios reprodutivos, analisado por meio da coleta de dados dos registros de hist?rico reprodutivo dos anos de 2017 a 2018 e observa??es do rebanho no transcorrer do estudo. O Teste de Qui- quadrado foi utilizado como modelo estat?stico para verificar a exist?ncia de associa??o entre a sorologia e dist?rbios reprodutivos, adotando um n?vel de confian?a de 95%. O resultado do estudo demonstra uma soropreval?ncia no rebanho de 27% (11/40) para N. caninum, contudo, ap?s an?lise estat?stica, n?o foi confirmada a associa??o entre soropositividade e dist?rbios reprodutivos no rebanho avaliado. Apesar da popula??o estudada estar infectada com o Neospora caninum, podemos inferir que anticorpos anti-Neospora caninum presentes em vacas leiteiras Girolandas do Setor de Bovinocultura de Leite da UFRRJ, n?o est?o associados ? ocorr?ncia de dist?rbios reprodutivosSubmitted by Celso Magalhaes (celsomagalhaes@ufrrj.br) on 2021-10-22T14:51:47Z No. of bitstreams: 1 2019 - Vin?cius Grangeia Gaia.pdf: 1998767 bytes, checksum: 1fafd6ff05f7979a60cbb59c0b07499b (MD5)Made available in DSpace on 2021-10-22T14:51:47Z (GMT).

description Bovine neosporosis is a parasitic disease caused by the protozoan Neospora caninum. The parasite has a worldwide distribution and mainly affects the dairy cattle herd, although, reported in beef cattle, being described as one of the main causes of abortion in cattle. It is of great relevance in cattle breeding, since the presence of the etiological agent is associated with bovine abortion worldwide, thus promoting direct and indirect economic losses. It can cause early embryonic death, fetal abortion or mummification, stillbirths and neonates with neurological symptomatology. This study was carried out in the Dairy Cattle Facility of the UFRRJ, located in the city of Serop?dica-RJ, where blood samples were collected from 40 dairy cows in reproductive age from cranial superfial epigastric vein, and the tested by indirect immunofluorescence (RIFI) for detection of anti-N.caninum antibodies. The serology was performed at the Laborat?rio de Coccidios e Coccidioses (LCC) of UFRRJ. From the serological results, we verified the association or not with the manifestation of reproductive disorders, analyzed through the collection of data from the records of reproductive history from 2017 to 2018 and observations of the herd in the course of the study. The Chi-square test was used as a statistical model to verify the existence of an association between serology and reproductive disorders, adopting a confidence level of 95%. The results of the study show a seroprevalence in the herd of 27% (11/40) for N. caninum, however, after statistical analysis, the association between seropositivity and reproductive disturbances in the evaluated herd was not confirmed. Although the studied population is infected with N. caninum, we can infer that N. caninum antibodies present in Giroland dairy cows of the dairy cattle sector of the UFRRJ are not associated with the occurrence of reproductive disorders
