Background: Tickborne diseases are frequent in tropical countries such as Brazil. Protozoa of the Babesia genus and bacteria of the Ehrlichia genus spread throughout the country with high prevalences in urban and rural areas, causing clinical or subclinical diseases in dogs. This study aimed to investigate the prevalence of infection from Babesia spp. and Ehrlichia chaffeensis in the dog population in the municipality of Ituberá, Bahia, Brazil, and to verify the risk factors associated with the infections.Materials, Methods & Results: A cross-sectional study was conducted, consisting of the following procedures: clinical examination and blood samples collection from 380 dogs and application of a structure questionnaire to dog owners to collect epidemiological data. All dogs were evaluated for the presence of ticks and clinical signs associated with the infections. Blood samples were collected and tested for Babesia spp. through capillary blood smears, indirect immunofluorescence assays (IFAT), and polymerase chain reaction (PCR); all the samples were also tested for E. chaffeensis through nested PCR. Intra-erythrocyte piroplasms were visualized in the blood smears of two animals (2/380; 0.5%) in the cytology exams. Anti-B. canis antibodies were detected in 140/380 (36.8%) dogs, at 1:40 dilution. By PCR, 147/380 (38.7%) dogs tested positive for infection by Babesia sp., but

Background: Leptospirosis is a zoonotic bacterial disease caused by Leptospira spp. that affects wild and domestic animals and humans. It has a worldwide distribution and causes public health problems and economic losses in livestock. The genus Leptospira is divided basically into two species: the Leptospira interrogans that is pathogenic and Leptospira biflexa that is considered saprobic. Cattle are an important source of infection, mainly to humans who work with these animals such as breeders, cowboys, slaughtermen, veterinarians and agricultural technicians. The temperature and rainfall indices of tropical and subtropical climate regions encourage the continuing disease outbreaks. In humans the symptoms are headache, fever, myalgia, nausea and vomiting. The identification of the disease is possible with some tests such as ELISA, immunofluorescence, bacterial culture, and Polymerase Chain Reaction (PCR). The aim of this work was to perform the molecular research for the presence of Leptospira spp. in kidneys of cattle refuted at a slaughterhouse. Materials, Methods & Results: Two hundred fragments of cattle kidney were collected at slaughterhouse located at Ilhéus, Bahia, Brazil. The macroscopic kidney refutation causes were nefritis, presence of cysts, congestion and presence of whitening and hemorrhagic areas. The kidney samples were placed in plastic containers identif


Leptospiras são bactérias espiroquetas móveis pertencentes ao gênero Leptospira que é composto por duas espécies: L. interrogans que é patogênica com mais de 200 sorotipos e L. biflexa que é sapróbica. A leptospirose tem ocorrência mundial, porém as regiões com climas tropical e subtropical favorecem a ocorrência da doença, sendo endêmica no Brasil. [...]

The aim of this study was to evaluate the effect of veterinary dental gel containing Aloe vera and green tea, with and without a water additive in preventing calculus formation in dogs after all animals were initially submitted to periodontal treatment. The preventive treatment was performed on 72 dogs, which 24 received treatment with the veterinary dental gel (G1), 24 received treatment with the gel associated with a water additive (G2), and 24 dogs did not receive any treatment (G3). The animals also were subdivided into three groups according to their diet. The gel was applied directly to the dogs' teeth and 500 ml of the additive was added to the water, three times a week. The animals' teeth were photographed every 30 days to observe the time of new deposition of dental calculus. The images were analyzed by MATLAB. The dogs in G1 showed average of new accumulation of dental calculus of 254.8 days, those in G2 also showed an average return of 258.6 days, and G3 showed an average return of 156.7 days. There was a statistical difference between G1 - G3 (p-value = 0,000007885) and G2 - G3 (p-value = 0,00004568). There was no statistical difference between the different food groups. We concluded that the gel used in this study, associated or not with the water additive, was effective in helping to maintain the dental health of the animals for a prolonged period after the surgic
