Foi determinada a prevalência de Ehrlichiose canina entre animais atendidos no Complexo Hospitalário Veterinário do Corozal da Faculdade de Medicina Veterinária da Universidade de Panamá. O levantamento foi realizado de forma retrospectiva com dados obtidos no período de janeiro de 2004 a dezembro de 2009. Para o trabalho, foram utilizados os registros dos casos clínicos de ehrlichiose canina, confirmados através de esfregaço sanguíneo, a raça e os aspectos demográficos (idade, sexo e local de origem) de cada animal. Os resultados revelaram que 10,12% dos animais atendidos (n = 1.452) mostraram-se positivos para o problema no período em análise. Esses animais eram de ambos os sexos com idade media de aproximadamente 3,6 anos. A prevalência mensal registrada foi de 9,98%, com taxa de infecção significativamente superior em 2008 (14,83%). O número de casos positivos foi significativamente superior nos meses de março, maio e setembro e menor no mês de fevereiro, destacando-se haver densidade de casos igual ou superior à média de maio a outubro. A raça e o local de origem dos animais foram identificados como fatores de risco.

The aim of this study was to determine the prevalence of canine Ehrlichiosis among animals treated at the Corozal Veterinary Hospital of the Faculty of Veterinary Medicine, University of Panama, Brazil. The survey was conducted retrospectively with data obtained from January 2004 to December 2009, based on the records of clinical cases of canine ehrlichiosis, confirmed with blood smear, race and demographics data (age, sex and place of origin) of each animal. The results revealed that 10.12% of the treated animals (n = 1452) were positive in the period under review. These animals were of both sexes with a mean age of approximately 3.6 years. The monthly prevalence recorded was 9.98%, with a significantly higher infection rate in 2008 (14.83%). The positive cases were significantly higher in the months of March, May and September and lowest in February, with a noteworthy density of cases equal to or higher than the average from May to October. Breed and place of origin of the animals were identified as risk factors.

Water used in hydrotherapy units of Nova Iguaçu and Nilópolis, Rio de Janeiro State, Brazil, was microbiologically analyzed. Thirty samples (5ml each) were weekly collected from September 2001 to June 2002 before the beginning and after the end of activities in the units. For analysis, routine techniques were used, which showed the presence of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella spp, Candida spp, Penicillium spp, Epidermophyton spp, Aspergillus fumigatus, Aspergillus niger, Aspergillus spp, Cephalosporium spp, Cladosporium spp, Trichophyton rubrum, and Trichophyton spp. Results indicated a need for improving hygienic conditions, suggesting that water might be a contamination source in the evaluated units.

The frequency of envenoming in Northwest counties of the Rio de Janeiro State, Brazil, from 1995 to 2000 was evaluated. Reports from the Municipal Secretariat of Health of these counties were used. The results demonstrated that, from 1997 to 1999, there was a shortage of notification, and 40 cases of envenomations caused by Bothrops snakes were registered. These cases were more common from February to October, and the lower limbs of male peasants were the mainly affected areas.

A prevalência e a manifestação das formas clinicas de Trypanosoma cruzi foram avaliadas em candidatos a doadores de sangue atendidos em um hospital geral de Nova Iguaçu, Rio de Janeiro, Brasil, no período de janeiro de 1997 a abril de 1999. A pesquisa sorológica foi realizada por meio do teste de hemaglutinação indireta e confirmada pelo ELISA. Os dados foram coletados considerando os exames clínicos, eletrocardiograma convencional, radiografia de tórax e ecocardiografia. Os resultados demonstraram que, apesar da prevalência ser de 1,17% (128 pacientes), principalmente entre homens com idade igual ou superior a 40 anos, 70,8%, principalmente de homens entre 19 e 39 anos, demonstraram alterações que permitiram o diagnóstico de cardiopatias e/ou esofagopatias, ratificando mais uma vez sua importância nos centros urbanos.

The prevalence and clinical forms of Trypanosoma cruzi were evaluated among blood donor candidates attended at a general hospital in Rio de Janeiro, Brazil, from January 1997 to April 1999. The investigation was done by means of the indirect hemagglutination test and was confirmed via ELISA. Data were collected from clinical examinations, conventional electrocardiogram, chest radiography and echocar-diography. The results showed that despite Trypanosoma cruzi prevalence of 1.17% (128 patients), mainly in males aged 40 years or over, 70.8% of these patients, mainly males aged 19 to 39 years, demonstrated abnormalities that allowed the diagnosis of cardiopathy and/or esophagopathy. This once again corroborates the importance of Trypanosoma cruzi infection in urban centers.
