Lung Worms

SUMMARYWe studied the component community of lung-worms of the harbour porpoise, attempting to establish the relative importance of ecological and evolutionary factors on its development. The lungs of 64 porpoises by-caught in Norwegian waters were examined for helminths. Three pseudaliid species were detected. The porpoises appear to be readily colonized by lung-worms, the structure of the component community of calves being fairly similar to that of the remainder. Prenatal and/or transmammary infections might partly account for these early infections. However, host age was correlated with the number of lung-worm species, suggesting that the lung-worms may have heteroxenous cycles similar to other metastrongyloids. The lung-worm species tended to co-occur more often than expected by chance. This pattern is commonly observed in communities formed by phylogenetic relatives. Mean species richness of lung nematodes differed significantly among mammalian orders. However, species richness of marine species seemed very similar to those of most terrestrial species. This evidence suggests that phylogenetic factors seem more important than ecological ones in determining the number of lung-worm species in mammals.

Eggs And Larvae

In 1890, Müller described, from the lung of the cat, a species of nematode which is now known as Aelurostrongylus abstrusus. In 1928, I was able to show that its true habitat was not the lung substance, but the pulmonary artery and its branches, and that its pathogenic action, was mainly, if not entirely, due to the presence of the developing eggs and larvae distributed throughout the lung tissue by the blood stream.

Schistosoma mansoni: larval damage and role of effector cell(s) in the synergy between vaccine immunity and Praziquantel treatment

Extent Of Damage

A number of authors have demonstrated that the schistosomicidal compound, Praziquantel (Pzq), depends for its action upon the immune status of the host (Sabah et al. 1985; Brindley & Sher, 1987; Doenhoff et al. 1987). We have attempted to define the synergistic interaction between immuno- and chemotherapy further, using the murine irradiated vaccine model of schistosomiasis mansoni. In vaccinated mice, resistance operates in the skin but not the lungs; drug targeted towards lung-stage worms exacerbates lung-phase immunity, however, as depicted by the increased number and size of inflammatory reactions in the pulmonary tissues. Parasites are often found trapped within such foci. In the present investigation, light and ultrastructural studies have been utilized to examine the nature and extent of damage inflicted upon lung-stage larvae recovered from day 6 Pzq-treated vaccinated mice. Such studies have revealed that damage involves muscle disorganization, internal disruption and occasionally, loss of the tegument; in the latter case, cells are often seen attached to the denuded lung worms. To identify the crucial cellular effector cell(s) involved in the synergy between immuno- and chemotherapy, cell depletion studies have been performed in vivo. It would appear from these experiments that eosinophils or lymphocytes rather than neutrophils or macrophages are important effector cells in this synergy. Histological studies argue in favour of eosinophils being the key effector cells.

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.
