Sarcocystis neurona, seroprevalence of antibodies in equines and research of oo...
Pellizzoni,Samantha Gusmão; Costa,Sônia Carmen Lopo; Mery,Raissa Barros Gracie; Barbieri,Jonata Melo; Munhoz,Alexandre Dias; Silva,Aísla Nascimento daAbstract The aims of this study were to determine the seroprevalence of Sarcocystis neurona antibodies in equines in the Ilhéus-Itabuna microregion (BA), and identify possible factors associated with infection. The presence of sporocysts/oocysts of Sarcocystis spp. was also verified in Didelphis spp. A total of 669 serum samples were collected from equines in 56 properties located in 12 municipalities in the re...
Survey of anti-Toxoplasma gondii antibodies in wild mammals captured from Atlan...
Brito Junior,Pedro de Alcântara; Rocha,Josiane Moreira; Silva,Caroline Araújo da; Oliveira,Priscylla Marcelly Vilanova; Correia,Joelande EsquivelAbstract The objective of this study was to investigate the frequency of antibodies to Toxoplasma gondii present in wild mammals that were trap captured in forest fragments in the State of Bahia, northeastern Brazil. A total of 368 individuals (246 rodents, 104 marsupials and 18 bats) were captured using live catch traps. Serum samples were tested using the modified agglutination test, with a cut-off point at 1...
Factors associated with the distribution of natural Toxoplasma gondii infection...
Munhoz,Alexandre Dias; Souza,Monia Andrade; Costa,Sonia Carmen Lopo; Freitas,Jéssica de Souza; Silva,Aísla Nascimento da; Lacerda,Luciana CarvalhoAbstract The aim of this study was to determine the frequency and factors associated with Toxoplasma gondii in naturally infected equids in northeastern Brazil. Serum samples from 569 equids (528 horses, 8 mules and 33 donkeys) were subjected to the indirect fluorescent antibody test. Generalized linear models were used to evaluate associated factors. Among the 569 animals sampled, 118 (30.6%) living in rural a...
Eimeria spp. (Apicomplexa: Eimeriidae) of marsupials (Mammalia: Didelphimorphia...
Fehlberg,Hllytchaikra Ferraz; Brito Junior,Pedro de Alcântara; Alvarez,Martín Roberto del Valle; Berto,Bruno Pereira; Albuquerque,George RêgoAbstract The occurrence of Eimeria Schneider, 1875 in mammals of the order Didelphimorphia indicates the infection-predisposition of these animals, which in turn is mainly determined for their eating habits. The objective of this work was to evaluate the parasitism of Eimeria spp. in marsupials of the Atlantic Forest of the southern region of Bahia. Fecal samples were collected from marsupials captured in the r...
Epidemiology of Eimeria infections in sheep raised extensively in a semiarid re...
Souza,Luiz Eduardo Barreto de; Cruz,Jurandir Ferreira da; Teixeira Neto,Milton Rezende; Albuquerque,George Rêgo; Melo,Antonio Diego BrandãoAbstract The aim of this study was to identify and determine the prevalence of Eimeria species affecting sheep raised extensively in a semiarid region of Brazil. Fecal samples of native sheep were collected during the rainy and dry seasons. The degree of infection was determined by counting oocysts per gram (OPG) of feces, and the morphometric method was used for species identification. Oocysts were found in al...
Bovine babesiosis and anaplasmosis complex: diagnosis and evaluation of the ris...
Amorim,Lucimar Souza; Wenceslau,Amauri Arias; Carvalho,Fábio Santos; Carneiro,Paulo Luíz Souza; Albuquerque,George RêgoDirect diagnoses were made by using - blood smears and nested PCR (nPCR) tests on 309 blood samples from crossbred dairy cattle in the municipality of Ibicaraí, Bahia. From diagnostic blood smear slides, the observed parasitic frequencies were 31.1% for Anaplasma marginale and 20.4% for Babesia sp. From nPCR diagnoses, they were 63% for A. marginale, 34% for Babesia bigemina and 20.4% for Babesia bovis. There w...
Prevalence and risk factors associated with anti-Toxoplasma gondii antibodies i...
Guimarães,Luciana Afonso; Bezerra,Rodrigo Alves; Rocha,Daniele de Santana; Albuquerque,George RêgoIn this study, we aimed to determine the prevalence ofToxoplasma gondii antibodies and identify risk factors associated with this infection in sheep from the southern region of Bahia state. Between February and December 2010, 795 sheep from 31 farms located in nine municipalities were tested. We found seroprevalence of 30.2% (240/795), with titers of 64 (38.3%), 256 (34.2%), 1,024 (18.3%), and 4,096 (9.2%) by I...
Risk factors and clinical disorders of canine ehrlichiosis in the South of Bahi...
Carlos,Renata Santiago Alberto; Carvalho,Fábio Santos; Wenceslau,Amauri Arias; Almosny,Nadia Regina Pereira; Albuquerque,George RêgoThe aim of this work was to study the clinical disorders and risk factors of canine ehrlichiosis in Ilhéus and Itabuna, Bahia, and compare different diagnostic methods. Blood samples were collected from 200 dogs. Each dog was clinically examined. A questionnaire was used to evaluate the risk factors. The blood samples were analyzed using the Dot-ELISA test; hematometry, platelet counts and searches for morulae ...
