In 2006, 725 horses aged 8 months to 16 years from different farms from the southern-eastern part of Poland were examined post-mortem for the presence of botfly larvae. One hundred and four horses (14.75%) demonstrated the presence of botfly larvae. An average infection rate was 52 larvae but low rate dominated. The larvae found belonged to Gasterophilus intestinalis and Gasterophilus nasalis. The 3rd instars dominated in the infected horses; however, more than 25% of the horses harboured both 2nd and 3rd instars.
Two hundred and seven weaned foals aging 6 to 12 months from small farms in the Lublin region were examined in the years 2005 to 2007. The investigations were carried out using flotation and sedimentary flotation methods, and McMaster's quantitative method modified by Wetzel. Eimeria leuckarti oocysts were found in 19 (9.18%) of the foals. The horses demonstrated occasionally clinical signs (four horses), and only two foals suffered temporary diarrhoea. The number of oocysts excreted via faeces was generally low and their presence in the faeces was detected irregularly. The sedimentary flotation method was the most effective considering the identification of E. leuckarti invasion.
In the years 2006-2009 coproscopic investigations of 1550 horses from central and eastern Poland have been conducted. Flotation, decantation and sedimentation-flotation methods were used. Parasitological autopsies of 950 horse livers were carried out. Fasciolosis was confirmed intra vitam in one live horse (0.07% examined) and in one horse post mortem (0.11%). Despite the fact that the invasion of Fasciola hepatica occurs in Poland sporadically, it should nevertheless be considered in the differential diagnosis of some diseases of horses.
The aim of the study was to determine the prevalence and intensity of gastrointestinal parasites in horses from various management systems. The study included 296 horses of different breeds and ages (from 6 months to 20 years), of both sexes, coming from various management systems: group 1 – horses using natural pastures, group 2 – horses pastured on field pastures created by man, group 3 – horses using sand areas. Faeces samples were collected directly from the rectum 1–2 days before worming. Each sample was examined macro- and microscopically (McMaster method). The number of oocysts/eggs per gram of faeces (OPG/EPG) and parasite abundance (average representation of parasites in relation to all animals). The results were subjected to statistical analysis using the Kruskal-Wallis test. Total prevalence of parasites in all groups was 66.89%: E. leucarti 0.68%; Anoplocephalidae 4.73%, P.equorum 9.46% and Strongylidae 64.19%. Total prevalence per group was the following: 1 – 57.43%; 2 – 26.69%; 3 – 6.38%. In all management systems, the dominating parasites belonged to Cyathostominae (group 1 – 77.65%, group 2 – 70.89%, group 3 – 4.25%). The prevalences of P. equorum, Anoplocephalidae, E. leucarti in each group were as follows: group 1 – 10.59; 3.53; 0.59%; group 2 – 11.39; 10.13; 1.27%; group 3 – 2.13; 0; 0%.The average intensities of Strongylildae, P. equorum, Anaplocephalidae and E. leucarti in groups were as follows: group 1 – 606.44; 519.44; 50; 50; group 2 – 472.32; 261.11; 62.5; 50; group 3 – 1150; 450; 0; 0. On the other hand, the average abundances in each group were the following: group 1 – 473.67; 55; 1.76; 0.29; group 2 – 334.81; 29.75; 6.33; 0.63; group 3 – 48.94; 9.57; 0; 0. The statistical analysis did not reveal statistically significant differences between the management system and invasion intensity. However, the analysis, taking into consideration a correlation between the management system and abundance, revealed statistically significant differences. The differences were observed between groups 1 and 3 (pi = 0.0000001) and between groups 2 and 3 (pi = 0.0000001).
The purpose of the research was to determine the level of contamination of dogs’ and cats’ hair with parasite eggs. The samples of hair of 122 pet dogs and 15 cats from urban areas and 44 dogs from the countryside were investigated. Parasite eggs were examined by the sedimentation-flotation method. The eggs were removed from hair with Tween 80 solution, sedimentation was carried out, subsequently the sediment was dissolved in a NaCl+saccharose solution and after a flotation microscopic preparations were made. Parasite eggs were found on the hair of 10 (6.02%) dogs and 2 (13.33%) cats. Only 14 eggs were found: Ancylostomatidae, Ascaris spp., Taenia spp., Toxocara spp., Toxascaris leonina, Trichuris spp. Half of them belonged to Toxocara spp. Most of the eggs had proper structure and in the future they could have been dangerous for animals and humans.
