Azevedo Filho,Paulo Cesar Gonçalves de; Ribeiro-Andrade,Müller; Santos,Jomel Francisco dos; Reis,Arthêmio Coelho dos; Pinheiro Júnior,José WiltonAbstract Livestock in the Amazon has grown significantly and, although neosporosis in cattle has been reported worldwide, there is no information about N. caninum in production systems in the state of Amazonas. The objective of this study was to determine the prevalence of anti-Neospora caninum antibodies in cattle, their spatial distribution and the risk factors associated with N. caninum infection in the stat...
Occurrence of anti-Toxoplasma gondii antibody and evaluation of risk infection ...
Rizzo,Huber; Jesus,Taile K.S.; Alcântara,Adrianne M.; Carvalho,Jeferson S.; Pinheiro Júnior,José Wilton; Mota,Rinaldo A.; Silva,Tatiane R.ABSTRACT: The objective was to determine, through indirect immunofluorescence reaction (RIFI, 1:64), the occurrence of IgG antibodies to Toxoplasma gondii and the risk factors associated with infection in goats in the state of Sergipe. To this study were used 675 samples of blood of animals from 41 farms of the three state mesoregions from 2013 to 2014. The occurrence of seropositive goats was 30.07%, with 90.2...

Valença,Sandra Regina Fonseca de Araújo; Ribeiro-Andrade,Müller; Moré,Gastón; Albuquerque,Pedro Paulo Feitosa de; Pinheiro Júnior,José WiltonAbstract The aim of this study was to determine the prevalence of infection by Sarcocystis neurona in horses and identify potential risk factors. Were analyzed 427 samples from 36 farms in 21 municipalities in the Alagoas State, Brazil. Presence of anti-S. neurona antibodies was diagnosed by indirect immunofluorescence antibody test (IFAT) and was confirmed using the immunoblot test. Risk factors were assessed ...

Santos,Sandra Batista dos; Melo,Renata Pimentel Bandeira de; Silva,Luana Thamires Rapôso da; Oliveira,Júnior Mário Baltazar deABSTRACT: The present study aimed to investigate contagious agalactia (CA) in flocks from Pernambuco State. The study involved 225 goats and 63 ewes; 288 milk samples and 100 vaginal swabs were collected in total. The PCR assays were carried out using specific primers to Mycoplasma agalactiae and the Mycoplasma mycoides cluster. Among the goat’s milk samples,12.0% (27/225) were positive for Mycoplasma agalactia...

Indirect diagnostic tests for the detection of subclinical mastitis in dairy go...
Peixoto,Rodolfo de Moraes; Araújo,Renata de Moraes Peixoto; Peixoto,Luciana Jatobá e Silva; Reges,Ariel Marques; Alves,Ana Paula PereiraABSTRACT: The aim of the present study was to assess two diagnostic techniques (California mastitis test (CMT) and the somatic cell count (SCC)) that can diagnose mastitis in dairy goats. Experimental infection was conducted using 20 mammary glands, a strain of Staphylococcus aureus, an infectious dose of 1.2x108CFU mL-1 and a volume of 1mL per mammary gland. The CMT and the SCC were used to detect subclinical ...
