PNEUMONIA VERMINOSA OF WILD BOARS

Abstract

In our country a certain number of wild boars is controlled and reared on enclosed hunting ground, while a number of free-ranging population is mainly unknown. The control of health status of wild boar population is quite demanding and it is not easy to achieve. Also, often is not possible entirely to perform a complete diagnostic examination in wild boars in each evaluated case. The aim of this research was to evaluate the clinical signs and pathomorphological changes in the suspicious cases on the occurrence of the verminous pneumonia in wild boars. The material for this research included three hunting grounds in Vojvodina, where clinical signs of health disorders and dead of young categories of wild hoags were recorded. The following research methods were applied: epidemiological, clinical and pathological examination of dead wild boars, hystological examination of the lung tissue samples and parasitologial examination. In all examined cases, macropathogical examination revealed changes dominantly in the respiratory tract. By pathohystological and parasitological examination the presence of lung worms in the trachea, bronchi and in posteroventral parts of the diaphragmatic lung lobes were detected (Pneumonia verminosa). In conslusion, the achieved results strongly suggest that Metastrongylus sp. represent economically important helmintosis of wild boars in our climatic conditions. Discovered parasitic infestations in the evaluated wild boars are economically significant because of retardation in the growth and weigh gain, and may be the cause of dead or discarding the meat in the case of cachexia, hydremia.
