The purpose of this study was to determine the frequency of canine rhabdomyosarcoma based on its histopathological classification, that were diagnosed in the histopathology laboratory of the Veterinary Faculty of San Marcos University, Lima, Peru in the period of January 2000 to December 2008. A total of 63 cases of canine rhabdomyosarcoma were diagnosed out of 1125 canine neoplasic tumors (5.6 ± 1.3%). Among this, only 47 cases were possible to classify where 27 cases (57.4%) corresponded to embryonal rhabdomyosarcoma, 19 (40.4%) to alveolar rhabdomyosarcoma, and one case (2.1%) to pleomorphic rhabdomyosarcoma. The most frequent region of the body affected by the embryonal type was the head and neck, where 6 to 10 year-old animals were the most affected.

The aim of this study was to detect the frequency of Salmonella sp by isolation techniques in pork carcasses intended for human consumption. Three hundred carcasses from two slaughterhouses in Lima, Peru were studied. Samples were taken by swabbing the skin of the head, abdomen, back and leg, representing 1200 subsamples. They were taken to the laboratory in Falcon tubes with buffered peptone water, and processed following the protocol for isolation of bacteria based on ISO 6579:2002. The isolates were identified by biochemical tests and specific antisera. In 6.3 ± 2.4% (19/300) of carcasses and 1.8% (21/1200) of subsamples were detected Salmonella sp. The highest frequencies of isolates were obtained from the head (33.3%, 7/21) and the abdomen (33.3%, 7/21). The isolates were serotyped and identified as Salmonella enterica subesp. enterica serotype Derby. The results confirm the need t...
