| Leptospirosis is an important zoonosis that causes reproductive disorders in swine. The isolation of leptospires from aborted fetuses, stillbirths and weak piglets was obtained in several occasions, however, the bacteria was never isolated from apparently healthy piglets born from apparently healthy infected dams. Six sows of the Landrace breed with a known date of service and pregnancy confirmed by ultrasonography were infected intravenously with 5ml of Leptospira interrogans serovar Canicola inoculum between 76 and 90 days of gestation, and one week after farrowing, at least one piglet per sow was euthanized and samples of liver, kidneys, lungs, heart, spleen and gastric content were taken and examined by PCR. Reproductive disorders or any clinical sign... |

| Foram testados, pela técnica de soroaglutinação microscópica aplicada à leptospirose, 329 cães provenientes do município de Monte Negro, RO, dos quais 156 eram da área urbana e 173 da área rural. Simultaneamente foi aplicado questionário para verificar a existência de possíveis fatores de risco pela regressão logística. Abordaram-se questões referentes a idade, sexo, dieta, tipo de criação, ambiente, contato com outras espécies e hábito de caça. Foram detectadas reações com títulos >100 em 27,3%, com 90 cães positivos ao agente, das quais 23,7% eram da área (37/156) urbana e 30,6% (53/173), da área rural (P>0,05). Os sorovares predominantes, reatores com títulos mais elevados, foram Autumnalis (22%), Pyrogenes (12%), Canicola (10%) e Shermani (7,5%).... |

| Leptospirosis is a worldwide infection that affects many species, including wild animals. The present study aimed to detect Leptospira spp. antibodies in 17 captive coatis (Nasua nasua) by the microscopic agglutination test (MAT). Nine (52.94%) animals tested positive and the following serovars were identified: Copenhageni (22.22%), Shermani (22.22%), Andamana (11.11%), Wolfii (11.11%) and Pyrogenes (11.11%). Two samples presented coagglutination, one (11.11%) for Hebdomadis and Wolfii, and another (11.11%) for Hebdomadis, Hardjo and Wolfii. The current study revealed the presence of the infection even in animals without any clinical signs, reinforcing the possibility that wild animals in captivity may be infected by leptospire serovars, thus enabling... |

| In the recent years, the wild boar (Sus scrofa) trade has increased in Brazil. The present study aimed to detect Leptospira spp. infection in 308 blood samples from wild boars bred in São Paulo state, Brazil. The microscopic agglutination test (MAT) was performed using 29 serovars. Sixty three (63; 20.45%) animals tested positive against the serovars Hardjo (29/63; 46.0%), Copenhageni (11/63; 17.4%), Pomona (8/63; 12.7%), Pyrogenes (4/63; 6.3%), Wolfii (4/63; 6.3%), Autumnalis (3/63; 4.7%), Icterohaemorraghiae (2/63; 3.1%), and Hardjo-miniswajezak (1/63; 15.8%). These results indicate that captive wild boars were infected with Leptospira spp. and may represent a source of infection to humans and other animals. |

| Leptospirosis is a globally distributed emerging zoonosis. Dogs are commonly affected and although other serovars can cause canine leptospirosis, Leptospira interrogans serovar Canicola is primary found in these animals. A retrospective study was conducted using a database of 1195 dogs tested for Leptospira infection from 2003 to 2010 at the Laboratory of Zoonosis Diagnosis at the Veterinary Hospital of São Paulo State University (UNESP) in Botucatu, São Paulo state, Brazil. The seroprevalence of infected dogs was 20.08% (240/1195), and the most prevalent serovars were Canicola (6.7%), Copenhageni (5.0%), Icterohaemorrhagiae (2.9%), Autumnalis (2.9%), Pyrogenes (2.8%), Pomona (2.0%), Hardjo (2.0%), Australis (1.8%), Bratislava (1.6%), Cynopteri (1.4%),... |

| Brucellosis and leptospirosis are widely spread bacterial infections and dogs are the most important source of infection and reservoir for diseases. Dogs can disseminate the agents in the environment and transmit them to humans and/or other animals. The objective of this study was assess the occurrence of reactive to antibodies anti-Leptospira spp., Brucella canis and B. abortus in Belém and Castanhal, State of Pará, Amazon, Brazil. A total of 156 samples were randomly collected in the city of Belém and 158 samples in Castanhal. The anti-B. canis antibodies research was performed by Agar Gel Immunodiffusion (AGID) with and without 2-mercaptoethanol serum treatment (AGID-2ME). To assess the anti-B. abortus antibodies, the technique of Fast Seroagglutination... |

| ABSTRACT: Leptospirosis is a zoonosis that is widely distributed in tropical countries. This infection is also associated with reproductive losses in livestock, which has a significant economic impact. The objective of this study is to investigate the seroprevalence and risk factors associated with leptospiral infection in commercial sheep flocks from the northwestern mesoregion of Rio Grande do Sul. Serum samples were analyzed in 319 sheep using the Microscopic Agglutination Test (MAT). At the time of sampling, an individual and herd questionnaire was carried out to investigate the risk factors. On an individual level, positive reactions were observed in 5.6% (18/319) of the studied sera, with Sejroe being the most prevalent serogroup. Animals >3 years... |
