Roznorodnosc biologiczna kapilarii

Four nematode species are reported from bony fishes caught in the Weddell Sea. Two species of cystidicolids, Cystidicola beatriceinsleyae (Holloway et Kiewer, 1969) and Ascarophis nototheniae Johnston et Mawson, 1945, were found in Lycodichthys antarcticus Pappenheim, 1911, whereas one capillariid, Capillaria (Procapillaria) sp., and one anisakid, Paranisakiopsis weddelliensis sp. nov., in Macrourus whitsoni Regan, 1913. Capillaria (Procapillaria) sp. (only females were found) is characterised by: body 17.6-26.0 mm long; stichosome composed of 46-49 stichocytes; presence of a vulvar appendage, and eggs 77-82 × 37-42 µm. This is the first Capillaria species reported from fishes in the Antarctic. Paranisakiopsis weddelliensis sp. nov. is characterised by: body length of male and female 40-48 and 55-62 mm, respectively; lips up to 200 µm and interlabia up to 140 µm long; inconspicuous dentigerous ridge on each lip; 8-10 pairs of preanal and 4 pairs of postanal papillae; spicules equal or subequal, 420-620 µm; eggs 83-85 × 63-65 µm. P. weddelliensis is the first representative of this genus reported from the Antarctic.
The western capercaillie breeding program is aimed at the restoration and reintroduction of this bird species in Poland. Parasitic invasions may be one of the factors limiting the breeding effects. The aim of the paper is to present the parasitologic situation in aviary breeding centres in Leżajsk and Wisła Forest Divisions. The study material included 38 samples of faeces of western capercaillie taken from the floor of the aviaries in the breeding centres in Leżajsk and Wisła Forest District. The faeces were studied using flotation, decantation and the quantitative McMaster methods. The presence of only two parasitic genera was detected. Based on the results of morphological analysis, the coccidia was classified as Eimeria lyruri, while nematode as the species Capillaria (syn. Aonchoteca) caudinflata. The total average prevalence of parasitic invasion in the studied samples was 60.5%. In both studied aviaries, the dominating invasion was coccidiosis, with average prevalences of 55.3%. The eggs of nematodes from Capillaria were found in 34.2% of all studied samples. Monoinvasion was present in 31.6% while the mixed invasion of coccidiosis and capillariasis was found in 28.9% cases. Dispersive forms of the parasites were significantly more frequent in the faeces of hens (77.3%) than of cocks (37.5%). No statistically significant differences in invasion extensiveness between the two breeding centres were found. The invasions of both types of parasites in the studied flocks were of a low level (the average OPG was 268.2 while the average EPG of Capillaria sp. was 164.3). The average OPG/EPG values in both breeding centres were similar, which was confirmed by student t-test. Higher values of OPG/EPG were found in samples coming from hens than in those coming from cocks but the differences were insignificant.
The aim of the study was to determine the efficiency of a formulation containing essential oils from Origanum vulgare (Lamiacea) and Citrus spp. (Citraceae) in limiting the prevalence and intensity of parasitic invasions in ewes kept in an indoor management system. The study material was a group of 222 mother ewes of Polish Lowland breed. During the entire experiment, the animals were kept in an indoor management system with uniform environmental conditions. On the basis of the parasitologic analysis, the flock was divided into three groups. All groups were uniform from the perspective of genetic traits, age and environmental conditions. The differentiating factor was the addition of a preparation containing essential oils from Origanum vulgare and Citrus spp. in the dose of 4 kg/ton of feed. Group 1 – control group, non-supplemented diet (74 mother ewes); Group 2 – supplemented diet from third month of pregnancy to lambing (73 mother ewes); Group 3 – supplemented diet from third month of pregnancy to weaning (75 mother ewes). The experiment involved parasitologic tests aimed at the determination of prevalence and intensity of invasions of gastrointestinal parasites in mother ewes. The study material was faeces collected from the rectum of mother ewes before the start of the experiment and on day 2, 28, 42, 56 and 70 after lambing. On the basis of the observations, it was shown that continuous use of the preparation during the whole experimental period had a beneficial impact on reducing the prevalence of invasions of Eimeria spp. and Capillaria. However, it must be stressed that both the prevalence and the intensity of parasitic invasions in the studied flock was relatively low, and so the use of such a preventive method was feasible.
