Trichuriosis Infection and Coccidiosis in Landrace Pigs

Abstract

A one-month-old female Landrace pig died after being suspected of being infected with nematode worms and protozoa parasites. The purpose of this study was to establish a diagnosis of death from case pigs. The pigs were taken from a close house farm owned by Mr. Wayan Suastika in Payangan village, Gianyar, with a total population of 20 and had never been dewormed. Case pigs showed symptoms such as anorexia, experiencing blackish diarrhea mixed with a little blood, no appetite, and pale mucosa. The case pig died one day after being taken from the farm, and was necropsied on November 18, 2022 at the Veterinary Pathology Laboratory, Faculty of Veterinary Medicine, Udayana University. Organs that underwent changes such as the brain, trachea, lungs, heart, spleen, liver, kidneys and intestines were taken to the Veterinary Pathology Laboratory for histopathological examination. Examination of feces using the flotation method and the Mcmaster method, as well as making permanent preparations to identify worms were carried out at the Veterinary Parasitology Laboratory. The results of post-mortem examination found typical anatomic pathology in the form of haemorrhagic colon, necrosis and catarrhal or mucohemorrhagic enteritis with mucus, fresh blood and/or necrotic debris in the lumen, along with infection with nematode worms in the colon with a total of 235 individuals. From the results of stool examination, Trichuris suis worm eggs and Eimeria spp. oocysts were found. Based on the results of pathological and parasitological examinations, it can be concluded that cases of death in pigs are caused by Trichuriosis and Coccidiosis. As a suggestion, pigs should be kept in cages with floors made of concrete or cement. If an earthen yard is used, excreta disposal should be regular and the manure disposal site should be made of closed concrete wells so as not to attract beetles.
