mecA positive Staphylococcus spp. in bovine mastitis, milkers, milking environm...
Silva,José Givanildo da; Camargo,Anderson Carlos; Melo,Renata Pimentel Bandeira de; Aragão,Breno Bezerra; Oliveira,Junior Mário Baltazar deABSTRACT: This study detected the presence and distribution of mecA in Staphylococcus spp. in the dairy production environment at farm level in Brazil. We analyzed 335 samples of mastitis cow milk, 15 samples of nostrils and hand swabs from milkers, 14 teat cup swabs, and 9 milking buckets swabs. Initially, the samples were subjected to microbiological analysis to detect Staphylococcus spp. and then S. aureus a...
Genetic traceability of Staphylococcus aureus strains isolated from primiparous...
Silva,Amanda Thaís Ferreira; Silva,José Givanildo da; Aragão,Breno Bezerra; Silva,Núbia Michelle Vieira da; Vasconcelos,Priscylla CarvalhoABSTRACT: This research aimed to investigate the genotypic relatedness of 18 Staphylococcus aureus strains isolated from intramammary infections in primiparous cows and extramammary sites on five dairy herds by rep-PCR using RW3A primers, and by PFGE using the endonuclease SmaI. The isolates were also evaluated in vitro for the susceptibility against beta-lactam antimicrobials drugs (penicillin and oxacillin), ...
Methicillin-resistant Staphylococcus epidermidis in handler of cheese made with...
Aragão,Breno Bezerra; Trajano,Sabrina Cândido; Melo,Renata Pimentel Bandeira de; Silva,Bruno Pajeú e; Mota,Rinaldo AparecidoABSTRACT: In the Northeastern Brazil, artisanal cheese production is an important local economic activity for small producers. Methicillin-resistant Staphylococcus is responsible for causing infection in animals and humans. This study described the first detection of methicillin-resistant S. epidermidis isolated in the nasal cavity of a handler of coalho cheese made with goat’s milk in Northeastern Brazil. This...
Monitoring the outbreak of equine glanders in Alagoas, Brazil: Clinical, immuno...
Rocha,Larissa Otaviano da; Lima,Luiz André Rodrigues de; Albuquerque,Rosângela Maria Santos de; Lages,Sônia Luisa SilvaABSTRACT: Glanders is an infectious and often lethal zoonotic disease of equines caused by the bacterium, Burkholderia mallei. This condition is characterized by respiratory, lymphatic, and cutaneous lesions. In this study, we monitored the development of clinical symptoms in animals naturally infected with B. mallei across different equine breeds and also isolated and characterized the disease-causing bacteria...
Neospora caninum infection in cattle in the state of Amazonas, Brazil: seroprev...
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...
Seroprevalence, spatial distribution and risk factors associated with Toxoplasm...
Gomes,Daniella Ferreira Cordeiro; Mendes,Lucas Andrade; Dias,Juliana Moraes; Ribeiro-Andrade,Müller; Oliveira,Pollyanne Raysa Fernandes deAbstract Little is known about Toxoplasma gondii infection among cattle living in the Cerrado (Brazilian savanna) biome in Brazil. In particular, there is no epidemiological data relating to infection in quilombo lands, i.e. areas settled by Afro-descendants of escaped slaves. The aim of this study was to determine the prevalence, spatial distribution and risk factors associated with T. gondii infection among c...
Vertical transmission and kinetic of antibodies anti-Neospora caninum in natura...
Feitosa,Thais Ferreira; Costa,Flávia Teresa Ribeiro; Bezerra,Roberto Alves; Álvares,Felipe Boniedj Ventura; Ferreira,Larissa ClaudinoAbstract Aimed with this study to evaluate vertical transmission of Neospora caninum in naturally infected sheep and to monitor the kinetics of antibodies against this protozoon in their lambs. Therefore, 48 pregnant ewes, from five herds, were divided into two groups: G1 - positive for anti-N. caninum antibodies, with 19 animals; and G2 - seronegative, with 29 animals. Blood samples were taken from the ewes an...
Low prevalence of infection by Sarcocystis neurona in horses from the State of ...
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 ...
Epidemiology of Mycoplasma agalactiae and Mycoplasma mycoides cluster in flocks...
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...
Hematological profile of captive bearded capuchin monkeys (Sapajus libidinosus)...
Ferreira,Adriano Fernandes; Queiroga,Felisbina Luísa; Mota,Rinaldo Aparecido; Rêgo,Eneida Willcox; Mota,Stéphanie Machado; Teixeira,Magda GuedesABSTRACT: Bearded Capuchin or Black-striped Capuchin monkeys (Sapajus lidibinosus) are New World robust capuchin monkeys widely used in medical research. Few data are available concerning hematological reference values for these species, with no studies available from the Northeast region in Brazil. The aim of this study was to determine the hematological reference values for healthy bearded capuchin monkeys an...
