The objective of this study was to determine the seroprevalence leptospirosis and predominant serogroups in serological tests ruminants performed at Transmissible Diseases Laboratory Federal University Campina Grande, Patos, Paraíba, northeastern Brazil, between 2010 2017. This research included records for from 5594 animals, including 1527 cattle, 1761 goats, 2170 sheep, 136 buffaloes four Brazilian states (Paraíba, Pernambuco, Maranhão, Rio Grande do Norte). Of serum samples, 662 were...
Bovine leptospirosis causes economic losses and raises public health concerns. It is possible that there are peculiarities in the epidemiology of regions with a semiarid climate, such as Caatinga biome Brazil, where climate hot dry, etiological agent require alternative routes transmission. This study aimed to close knowledge gaps diagnosis Leptospira spp. infection cows from biome, Brazil. Samples blood, urinary tract (urine, bladder kidney) reproductive (vaginal fluid, uterus, uterine...
A cross-sectional study based on a planned sampling was carried out to determine flock-level risk factors associated Leptospira spp. infection in dairy goat flocks semiarid region of Northeastern Brazil. Serum samples from 975 adult goats 110 were examined for antibodies by MAT using 24 serovars. structured questionnaire focusing leptospirosis completed each flock. Of the 48 (43.6%; 95% CI: 34.2–53.4%) presented at least one seropositive animal, and most frequent serovar Autumnalis (10.9%)....
Este trabalho teve como objetivo determinar a prevalência de rebanhos ovinos positivos (focos) e animais soropositivos para leptospirose na região semiárida do Estado da Paraíba, bem identificar fatores risco. Foram colhidas amostras sangue 1.275 procedentes 117 em 19 municípios mesorregião Sertão, Paraíba. Para o diagnóstico sorológico foi utilizado teste soroaglutinação microscópica (SAM), com 24 sorovares Leptospira spp. antígenos. Um rebanho considerado positivo quando apresentou pelo...
To determine the presence of Brucella ovis in ovine from Paraíba State, Northeast region Brazil, 80 animals slaughtered public slaughterhouse Patos city were used. Before slaughter, blood samples collected by jugular venopuncture each animal, and after testicles, epidydimus uterus aseptically collected. For serological diagnosis B. abortus infections, agar gel immunodiffusion (AGID) Rose Bengal (RBT) tests carried out, respectively. In addition, microbiological culture polymerase chain...
Este trabalho teve como objetivos determinar a prevalência de propriedades caprinos leiteiros positivas e animais soropositivos para leptospirose no semiárido paraibano. A amostragem foi delineada determinação da (focos) infecção por Leptospira spp. No total, foram colhidas amostras sangue 975 procedentes 110 leiteiras localizadas Munícipio Monteiro, microrregião do Cariri Ocidental, Estado Paraíba. Para o diagnóstico spp., utilizado teste soroaglutinação microscópica (SAM), utilizando...
Leptospirosis is an infectious disease that affects domestic animals, wild and humans. It represents a public health problem has important economic impact on livestock. This study aims to investigate the importance of genital transplacental infection in epidemiology leptospirosis cows maintained Caatinga biome conditions, Northeastern Brazil, as well reporting organs colonized by Leptospira spp. embryos fetuses. Blood, urinary tract (urine, bladder, kidney), reproductive (vaginal fluid,...
RESUMO Foram colhidas amostras de placenta, ampola do ducto deferente e glândulas vesiculares 80 ovinos abatidos no matadouro público Patos, Estado da Paraíba, região Nordeste Brasil para isolamento Leptospira spp., bem como sangue a pesquisa anticorpos anti-Leptospira spp. O meio Ellinghausen-McCullough-Johnson-Harris (EMJH) modificado com adição 10% soro coelho foi usado o agente técnica soroaglutinação microscópica sorológica. Os cultivos foram observados semanalmente por microscopia...
Few data are available on the prevalence and risk factors of Chlamydophila abortus infection in goats Brazil. A cross-sectional study was carried out to determine flock-level C. from semiarid region Paraíba State, Northeast Brazil, as well identify associated with infection. Flocks were randomly selected a pre-established number female > 12 mo old sampled each these flocks. total 975 serum samples 110 flocks collected, structured questionnaire focusing for given farmer at time blood...
The aim of the present study was to detect and identify Mycobaterium spp. in 50 samples coalho cheese sold Northeast region Brazil. Of analyzed samples, 35 were produced by artisanal process, using raw milk, 15 originated from industrialized establishments that pasteurize milk. Conventional real-time nested PCR for rv2807 gene M. tuberculosis complex performed directly samples. Samples grown simultaneously Stonebrink medium, conventional bacterial isolates with primers flank differentiation...
Este trabalho teve como objetivo determinar a prevalência de rebanhos ovinos positivos (focos) e animais soropositivos para Brucella ovis na mesorregião do Sertão, Estado da Paraíba, Nordeste Brasil, bem identificar fatores risco. Foram colhidas amostras sangue 1.134 procedentes 103 em 17 municípios. Para o diagnóstico sorológico infecção por B. foi utilizado teste imunodifusão gel ágar (IDGA). Um rebanho considerado positivo quando apresentou pelo menos um animal soropositivo. Das...
A cross-sectional study based on planned sampling was carried out to determine flock-level risk factors associated with Toxoplasma gondii antibody prevalence in dairy goat flocks a semiarid region of northeastern Brazil. Serum samples from 975 adult goats 110 were examined by indirect immonufluorescent test (IFAT), using cut-off point at 1:64 dilution. From the flocks, 77 presented least one seropositive animal, corresponding 70% (95% CI: 60.5-78.4%). Out animals, 177 (18.1%; 95% CI =...
A total of 8,058 male and female mixed-breed goats 1-4 years age were slaughtered over a period 7 months at the public slaughterhouse Patos city, Paraíba state, in Northeast region Brazil; 822 animals inspected for gross lesions tuberculosis, 12 (1.46%) had suggestive tuberculosis mammary gland, lungs, liver mediastinal, mesenteric, submandibular, parotid prescapular lymph nodes. Presence granulomatous was confirmed submandibular node one (8.3%) goat histopathological examination...

ABSTRACT: An epidemiological survey aiming to determine the occurrence of anti-Leptospira antibodies and identify risk factors was carried out in horses Pajeú microregion, state Pernambuco. Sera from 100 38 properties four counties region were examined by microscopic agglutination test (MAT), using 24 Leptospira spp. serovars as antigens. Of samples tested, 28 (28%) positive. Most prevalent Patoc (35.71%), Butembo (32.14%) Sentot (14.30%). Supply pasture forage (odds ratio =7.80; 95%...
