Control measures recommended for goat gastrointestinal nematode infections afte...
Vieira,Vanessa Diniz; Correa,Franklin Riet; Vilela,Vinícius Longo Ribeiro; Medeiros,Márcia Alves de; Batista,Jouberdan Aurino; Azevedo,Sergio SantosABSTRACT: This study aimed to determine control measures for gastrointestinal nematodes in goats in the northeastern semiarid after analyzing the dynamics of gastrointestinal helminths during the drought, the evolution of the parasitic load after the first rains and the differences in susceptibility between goats of different categories and ages. Five farms were studied from March 2013 to January 2015. Feces we...
Canine leishmaniasis in the semi-arid region of Pernambuco, northeastern Brazil...
Evaristo,Anna Maria da Cruz Ferreira; Sevá,Anaiá da Paixão; Oliveira,Glauber Meneses Barboza de; Silva,Ivo Wesley Gomes da; Ferreira,Matheus SilvaAbstract This study aimed to determine the seroprevalence, factors associated with seropositivity to Leishmania infection in dogs and spatial analysis in six municipalities in the semiarid region of Pernambuco, Brazil. Blood samples were collected from 462 dogs, 77 in each municipality, and used for serological analysis [dual path platform (DPP®) and enzyme-linked immunosorbent assay (ELISA)]. Clinical signs of...
Serological detection and risk factors for equine piroplasmosis in the semiarid...
Souza,Eline Almeida Rodrigues de; Araujo,Andreina de Carvalho; Pires,Larissa Célly Souza Regis; Freschi,Carla Roberta; Azevedo,Sergio SantosAbstract Equine piroplasmosis, an economically important disease in horses, has so far not been reported in Pernambuco state, Brazil. This study aimed to evaluate the seroprevalence of anti-Babesia caballi and anti-Theileria equi antibodies based on the detection of these agents in equine blood and in ticks on horses in the municipality of Petrolina, Pernambuco, northeastern Brazil. Blood samples were drawn fro...
Detection of CDT toxin genes in Campylobacter spp. strains isolated from broile...
Carvalho,Aline Feola de; Silva,Daniela Martins da; Azevedo,Sergio Santos; Piatti,Rosa Maria; Genovez,Margareth Elide; Scarcelli,ElianaCampylobacteriosis is a worldwide distributed zoonosis. One of the main virulence factors related to Campylobacter spp. in animals and humans is the cytolethal distending toxin (CDT), encoded by three adjacent genes (cdtA, cdtB, cdtC). The occurrence of Campylobacter spp. in samples of vegetables has not been reported in Brazil yet, and has seldom been described in the international literature. The detection of...
Seroprevalence and risk factors for cattle anaplasmosis, babesiosis, and trypan...
Costa,Valéria Medeiros de Mendonça; Ribeiro,Múcio Flávio Barbosa; Duarte,Amélia Lizziane Leite; Mangueira,Julia Marry; Pessoa,André Flávio AlmeidaThe seroprevalence of Anaplasma marginale, Babesia bigemina, Babesia bovis and Trypanosoma vivax and the risk factors for these infections were investigated in 509 cows on 37 farms in the semiarid region of Paraíba, northeastern Brazil. Cow serum samples were tested by means of immunofluorescence assay (IFA) against each specific antigen. The mean seroprevalence values per farm were 15.0% (range: 0-75%) for A. ...
