The aim of the present study was to assess the severity of periodontal disease in upper premolars compared to the lower premolars in canine patients older than one year old at the Small Animal Clinic of the Faculty of Veterinary Medicine of the Universidad Nacional Mayor de San Marcos, during the period October 2012 to March 2013. All teeth of 54 dogs were evaluated using the Veterinary Periodontal Index to stablish the presence and severity of periodontal disease. The results showed that 81.5% of dogs had some degree of periodontal disease and 40% of teeth were affected with some degree of periodontal disease. Moreover, there was an association between the presence of periodontal disease in tooth premolars and the maxillary or mandibular region, where periodontal disease was more frequent in the upper premolars.

The aim of this study was to determine the frequency of oral neoplasms diagnosed histopathologically in canine patients of the Small Animal Clinic of the Faculty of Veterinary Medicine of the Universidad Nacional Mayor de San Marcos (Lima, Peru) in the period of January 2009 till December 2013.

The aim of this study was to determine the antibiotic susceptibility of subgingivalbacteria in dogs with moderate to severe periodontal disease. Thirty dogs from fourshelters were sampled using sterile paper sheet tips at the bottom of the periodontalpocket in the fourth premolar and canine teeth of the upper right quadrant. The most frequent bacteria isolated were Porphyromonas gingivalis (50%), Bifidobacterium spp(20%), Prevotella intermedia (16.7%), Staphylococcus spp (30%) and enterobacteria(60%). The highest antibiotic susceptibility from isolated bacteria species was againstimipenem. The susceptibility against other antibiotics depended of the bacterial species.

The aim of this study was to determine the prevalence of Cryptosporidium sp in dogs of rural communities located in the districts of Ajoyani, Carabaya province and Palca and Santa Lucia, Lampa province, in Puno, Peru. Fecal samples were collected (n=123) from apparently healthy dogs of both sexes, older than one month. The ZiehlNeelsen modified technique was used for the diagnosis of Cryptosporidium sp. The overall prevalence was 26.8 ± 7.8% for Cryptosporidium sp and without significant association between the presence of the protozoa with the district, sex and age. The results show the presence ofCryptosporidium sp in dogs evidencing a possible zoonotic risk.

Se recolectaron 123 muestras fecales de canes aparentemente sanos, de ambos sexos y con edades mayores de un mes, y se analizaron mediante la técnica de Ziehl-Neelsen modificada para el diagnóstico de Cryptosporidium sp. La prevalencia general de Cryptosporidium sp fue de 26.8 ± 7.8%, sin encontrarse asociación significativa entre la presencia del protozoo con el distrito de procedencia, sexo y edad. Los resultados demuestran la presencia de Cryptosporidium sp en caninos evidenciando un posible riesgo zoonótico.

Serum levels of the asparte amino transferase (AST), creatine kinase (CK), the MB fraction of creatine kinase (CK-MB) and lactate dehydrogenase (LDH) enzymes were measured in adult dogs with cardiovascular disease to evaluate their potential use as predictors of myocardial damage in heart failure. Twenty five animals, irrespective of sex and breed, were studied: 10 of them were apparently healthy (G1) and the other 15 suffered of cardiovascular illnesses (G2). Blood samples were collected and the resulting sera was examined by spectrophotometry. The results indicated that only levels of CK-MB were statistically different (p<0.05) betwen the two groups. It is concluded that CK-MB can be used to predict progressive myocardial damage in dog´s heart failure.
