Freqüência sorológica antileptospírica em cães: sua correlação com roedores e fatores ambientais, em área territorial urbana / Antileptospirosis serological frequency in dogs: its correlation with rodents and environmental factors, in an urban area

RESUMO Com o objetivo de conhecer-se a freqüência sorológica antileptospírica em cães e sua correlação com roedores e fatores ambientais, na área territorial urbana de 32 km2 do Município de Botucatu, SP, colheram-se 1.000 amostras de sangue de cães, em 20 postos homogeneamente distribuídos. A prova diagnóstica utilizada foi a de soroaglutinação microscópica (SAM), com 24 sorovares de Leptospira spp. Das 1.000 amostras submetidas à prova, 17,9% foram reagentes. Os cães reagentes que tiveram contato com roedores (23,68%) mostraram-se significativos (p < 0,05) em relação aos reagentes que não tiveram contato (15,37%). Na correlação entre animais de residências ligadas (18,10%) ou não ligadas (13,63%) à rede pública de esgoto e a soropositividade, não se observou significância estatística (p > 0,05). Ocorreram reações para 20 sorovares, com maior importância para: castellonis (28,68%), autumnalis (19,12%), pyrogenes (17,65%), icterohaemorrhagiae (11,03%) e canicol (9,56%).

ABSTRACT The aim of this study was to ascertain the antileptospirosis serological frequency in dogs and its correlation with rodents and environmental factors in a 32 km2 urban area of Botucatu, SP, Brazil. One thousand blood samples were collected from dogs at 20 homogenously distributed stations. The microscopic serum agglutination diagnostic test (SAM) was used with 24 Leptospira spp. serovars. From the 1,000 samples tested, 17.9% were reactive. Reactive dogs who had contact with rodents (23.68%) were significant (p < 0.05) in relation to those without contact (15.37%). There was no statistical significance (p > 0.05) between seropositive animals from homes connected (18.10%) and not connected (13.63%) to the public sewage system. There were reactions to 20 serovars, the most important were: castellonis (28.68%), autumnalis (19.12%), pyrogenes (17.65%), icterohaemorrhagiae (11.03%), and canicola (9.56%).

Hepatozoonose canina: achados clínico-epidemiológicos em três casos / Canine hepatozoonosis: clinic-epidemiological data in three casest

Clinic-epidemiological data in canine infection by Hepatozoon canis were reported. Apatia, anorexia, prostaction, weight loss and muscle pain were the most-common clinical recognized signs. Blood smear was used as diagnosis method for the detection of H. canis gamonts in the neutrophils. Anaemia, leucocytosis, monocytosis and lymphopenia were observed in the haematological exams. Imidocarb dipropionate associated with tetracyclines and sulfamethoxasole-trimethoprim were used in therapy.(AU)

Tratamento da papilomatose canina com Propionibacterium acnes

Propionibacterium acnes as immunostimulant in oral canine papillomatosis treatment in 16 animals was studied. Regression of the pappiloma started being observed after the second aplication, with complete resolution in all dogs after the sixth aplication. These results suggest the use of P. acnes as an alternative in oral canine papillomatosis therapy.
