Ruminants often live in environments where the natural balance has been disturbed by humans. As a result, there is a transfer of parasitosis to domestic animals and sometimes humans. The aim of the study was to determine the annual species composition and level of gastrointestinal nematode infection of mouflon (Ovis aries musimon) from the half-open breeding colonizing areas of the Goleniowska Forest, and to assess the effectiveness of deworming. The course of the parasitic infection of mouflon depends largely on geoclimatic and breeding factors. These diseases are caused by more than 17 species of nematodes with varying degrees of pathogenicity. Due to the high degree of parasitic infections in deer, both in Poland and abroad, it is necessary to develop specific preventive programs using preparations with a broad spectrum of action.
The study involved mice of an inbred CFW line from the author’s own culture conducted according to the street light method (Lane Petter and Pearson 1971). All the animals, aged about 3 months and weighing 20 g each, were infected per os with 200 T. spiralis larvae per mouse. A total of 76 mice, divided into two groups, were used. Group I constituted the control and consisted of T. spiralis-infected mice, while Group II consisted of chitosan (chitosan adipinate)-treated mice receiving a dose of 0.4 mg per mouse, administered intra-peritoneally for 20 days (6 days prior to infection until day 13 post-infection). Four mice of each group were sacrificed by decapitation on invasion day 7, 14, 21, 28, 35, 42, and 60. Sections of the jejunum and mandibular muscle were used to prepare populations of cells involved in the inflammatory infiltration. The populations selected were the T (CD4+ and CD8+) lymphocytes and macrophages. The first were identified with immunofluorescence, using labelled monoclonal antibodies, while identification of the latter proceeded immunoenzymatically, with non-labelled monoclonal antibodies. In addition, the infected animals in each group were examined for the presence of parasites: on day 7, 10, 14, and 21 post-infection, the intestinal parasites were counted, while, the muscle-dwelling larvae being enumerated on day 60 post-infection. In this study, the macrophage count in the jejunum mucosa basement membrane of the chitosan-treated mice increased until day 21 post-infection and remained, until the observations were terminated, at a level higher than that in the control. On the other hand, the transversely striated muscles revealed, in addition to T CD4+ and T CD8+ lymphocytes, a stronger macrophage mobilisation throughout the period of observations. The chitosan-treated mouse jejunum were also a site of a faster removal (“expulsion”) of adult parasites than in the control, the muscle larval count in those mice being clearly lower than in the control.
Malaria remains a major health issue In the world, while in Poland no cases of the indigenous disease have been observed since 60-ties of the last century, but the number of cases imported from the epidemic areas is increasing. The aim of work was to analyse the epidemiology of malaria diagnosed and treated in the Department of Infectious Diseases and Hepatology, Pomeranian Medical University, Szczecin, Poland from 1.02.2010 until 31.01.2011. In total 11 cases were found, all diagnoses based on the thick and thin blood smear microscopy, alongside to the standard laboratory analyses.All clinical data presented are based on the case history. Results: Majoriry of cases reported travel to Sub-Saharan Africa (45%) or Indian subcontinent (27%). The travel was usually for recreational purposes, with significant proportion (45%) of patient not taking the malaria prophylaxis. Clinical course of infections was largely mild, with dominance of Pl. Falciparum parasitaemia. Fever was the most common clinical symptom (90%), while in the routine laboratory test no significant abnormalities, suggesting the disease, were found. Conclusions: malaria should be suspected in every case of the returning traveler with fever, especially if the travel was to the endemic area. The exclusion of the disease cannot be based on routine laboratory tests or quick immunoassays – thick and thin blood smear microscopy must be performed.
