The barn owl (Tyto alba) is protected as it is considered a beneficial species for agrosilvopastoral activities, the maintenance of ecosystems and for human health. The present descriptive study corresponds to an analysis of a barn owl carcass, where the bones of the pelvic, femoral, tibiotarsal, tarsometatarsal and phalangeal regions were studied. It is concluded that the studied specimen has bone structures similar to other birds, mainly raptors; however, the difference in sizes between the iliac crests, the depth of the fossa of the femoral head, the great fusion between the tibiotarsus and the fibula, the hypotarsus formed only by a lateral projection on the tarsometatarsal bone and the great development of the flexor processes of the nail phalanges.

The aim of this study was to describe the musculature of the pelvic limbs of a barn owl (Tyto alba). The specimen has powerful muscles, with a predominance in the development of the flexor muscles over the extensors. In general, there is similarity with the musculature described in other birds, especially raptors; however, it is important to highlight some differences, such as m. iliofibular is well developed and is located caudal and superficial to the m. lateral iliotibial; the m. femorotibial has only two heads; the ms. ambiens and fibular long were not observed in the specimen studied, but m. lateral thigh flexor was observed. The m. long digital flexor has only one head; the ms. perforating and perforated are highly fused and m. extensor digitorum longus I has a small muscular head.

The objective of the present study was to determine the prevalence of linguatulosis in bovine viscera in a slaughter house in Curicó, VII Region, Chile. The macroscopic examination of the liver, lungs, heart and the mediastinal, mesenteric and hepatic lymph nodes of 269 cattle was performed. In cases of lesions compatible with linguatulosis, the viscera were considered positive and these were observed under a stereoscope to reach the etiological diagnosis, considering as positive the lesions that presented one or more nymphs. The results showed that 11.89% of the cattle presented lesions compatible with linguatulosis in the viscera analysed and only one (0.37%) presented the positive etiological diagnosis of Linguatula serrata nymphs. The largest number of compatible lesions was found in the liver (81.8%), followed by mesenteric lymph nodes (9.1%), hepatic lymph nodes (6.1%) and lungs (...

The aim of this study was to determine the prevalence of findings compatible with hydatidosis and fertility of hydatid cysts in bovines of a slaughterhouse in Curicó, Chile. Lungs, livers, hearts, spleens and kidneys of 218 animals slaughtered in April 2017 were analyzed. The prevalence of findings compatible with hydatidosis was 12.4%, where 74.1% of affected animals presented lung cysts, 11.1% liver cysts and 14.8% of both types. Older animals concentrated the greatest number of findings. In samples of hydatid fluid from unilocular cysts a fertility of 6.25% was obtained. The prevalence of findings found was lower than the data described in national studies.
