Prevalencia de Ancylostoma spp. en lobos marinos (Zalophus wollebaeki) del Parque Nacional Galápagos en la Isla Santa Cruz.

Abstract

Currently, there are not many studies related to parasites in sea lions and overall, in the endemic specie of Galapagos sea lions, Zalophus wollebaeki. The present study focused on determining the presence of the parasite Ancylostoma spp. in the sea lions of the Santa Cruz Island in Galapagos, through the coprological method of flotation with mix solution between salt and sugar. The Ancylostoma is a nematode that affects animals and humans, and they are located in the fecal of the individuals that are infected. For the investigation, the recollection of fecal samples was done of 44 individuals, who were found in 12 different zones, within the Capitania, Muelle de la capitania, muelle de cabotaje, Muelle del Parque Nacional Galapagos and other zones. In the studied zones, it was obtained one sea lion with the presence of the Ancylostoma spp. and 14 sea lions with the presences of nine different parasites, within Toxocara canis, Dipylidium caninum, Uncinaria stenocephala, and others. Finally, it was used the Chi-Cuadrado statistic method to know if the variables of sex, age and zone have relation with the studied parasite (Ancylostoma spp.), giving the result that there is no significance between the variables and the parasite.
