South American Sea Lion Thanatocenotic Elements of in Sediments: Would be an Important Source of Environmental Contamination by Parasite Eggs-Juniper Publishers
JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES Abstract Bodies of animals in decomposition on coastal sediment of beaches represent risk to public health. This work has as aim to verify if copses of South American sea lion in decomposition at beach may be an important source of parasite eggs contamination. Were studied 10 carcasses O. flavescens in mild to moderate state of decomposition, found during systematic and weekly field trips in Brazilian south coast. Carcass faeces samples were aspirated and syringes, through the anus and rectum. A total of 40 sandy sediment samples around carcasses were analyzed. Additionally, 34 samples of faeces of live south sea lions were studied. Samples were processed using standard parasitological techniques. From faecal samples of live animals, immature females of C. austral were found. Helminthic or protozoa eggs were not found in none sample, neither in carcass nor in sandy sediment. This work po...
