Leptospira interrogans infection in tegu lizard (Tupinambis merianae), Brazil
Fernandes,Juciê Jales; Pinheiro,Tiago Junior; Costa,Diego Figueiredo; Araújo Júnior,João Pessoa; Malossi,Camila Dantas; Ullmann,Leila SabrinaABSTRACT: We used 12 tegu lizards (Tupinambis merianae) from northeastern Brazil, and we reported nine (75%) Leptospira sp. PCR-positive animals and six (50%) seropositive. Leptospira sp. DNA sequencing revealed 99% similarity with L. interrogans. Our findings indicated that this species may play a role in the transmission of human leptospirosis.
Diversity of enteric coccidia in pigs from the Paraíba Semiarid Region of North...
Araújo,Hosaneide Gomes de; Silva,Juliana Trajano da; Sarmento,Wlysse Ferreira; Silva,Samara dos Santos; Bezerra,Roberto Alves; Azevedo,Sérgio SantosAbstract There is great diversity in swine coccidia, which are responsible for causing intestinal disorders ranging from sporadic diarrhea to severe cases of hemorrhagic enteritis. Thus, determining the species of coccidia that affect the animals of a region and associating them with the characteristics of the farms become extremely important. The objective of this study was to determine the prevalence of cocci...
Serological diagnosis and risk factors for Coxiella burnetii in goats and sheep...
Souza,Eline Almeida Rodrigues de; Castro,Elaine Monalize Serafim de; Oliveira,Glauber Meneses Barboza de; Azevedo,Sérgio SantosAbstract Coxiella burnetii is a zoonotic agent transmitted mainly by small ruminants. In Brazil the disease has been classified as a notifiable disease since 2013, when human cases were reported. This study aimed to identify risk factors associated with the presence of anti- Coxiella burnetii antibodies in goats and sheep in a semiarid region of Northeastern Brazil. Sera of 412 goats and 403 sheep from municipa...
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 ...
Risk factors associated with seropositivity for Leishmania spp. and Trypanosoma...
Fernandes,Annielle Regina da Fonseca; Pimenta,Carla Lauise Rodrigues Menezes; Vidal,Ivana Fernandes; Oliveira,Gabriela Capriogli; Sartori,Raissa SaranAbstract The aim of this survey was to determine the seropositivity and risk factors forLeishmania spp. and Trypanosoma cruzi in dogs in the State of Paraíba, Northeastern Brazil. A total of 1,043 dogs were tested, and the serological diagnoses of Chagas disease (CD) and canine visceral leishmaniasis (CVL) was performed by the indirect fluorescent antibody test (IFAT). Animals that tested seropositive for both ...
Occurrences of gastrointestinal parasites in fecal samples from domestic dogs i...
Ferreira,Juliana Isabel Giuli da Silva; Pena,Hilda Fátima Jesus; Azevedo,Sérgio Santos; Labruna,Marcelo Bahia; Gennari,Solange MariaAbstract Occurrences of gastrointestinal parasites were assessed in fecal samples from 3,099 dogs in the metropolitan region of São Paulo, SP, that were treated at the Veterinary Hospital of the University of São Paulo Veterinary School. The samples were analyzed using the flotation and centrifugal sedimentation methods. The results were compared with those from previous studies (at different times). The freque...
Seasonal prevalence and mean intensity of Psoroptes ovis infestation in goats i...
Amorim,Malba Gean Rodrigues de; Azevedo,Sérgio Santos; Riet-Correa,FranklinTo determine the prevalence and seasonal variation of Psoroptes ovis (Delafond, 1858) mange in goats in the semiarid region of Paraíba, 541 crossbred goats of both sexes and different ages were examined between June 1999 and May 2001 and between August 2011 and December 2012, by washing their ear canals. The monthly prevalence of the infestation varied between 66.66% and 100% without significant differences (p ...

Vieira,Vanessa Diniz; Vilela,Vinícius Longo Ribeiro; Feitosa,Thais Ferreira; Athayde,Ana Célia Rodrigues; Azevedo,Sérgio SantosIn this study, we aimed to establish the prevalence and risk factors relating to gastrointestinal helminthiasis, and to characterize the sanitary management practiced among sheep herds in the Sertão region of the state of Paraíba, northeastern Brazil, based on factors that condition the ways of controlling these parasites in these herds. The research was carried out between April and July 2012. We visited 54 fa...
