The aim of this study was to evaluate the effect of flumequine on the percentage of peripheral blood leukocytes of carp, alpha naphthyl acetate esterase (ANAE) activity and proliferative activity of lymphocytes stimulated with concanavalin A (Con A) and lipopolysaccharide (LPS). Flumequine was administered to 40 carp, weighing 150 ± 10 g, at a dose of 12 mg/kg, once (group I) and four times, every 2 days (group II). Among white blood cells in flumequine, treated fish (group II) observed a decrease in percentage of lymphocytes and an increase of neutrophiles. Identification of the ANAE esterase activity in fish lymphocytes of the control group showed the advantage of positive cells over the negative ones and amounted to 62.65 ± 3.22%. After administration of flumequine in group II fish, this value decreased to 44.75 ± 3.70%. The present study clearly demonstrated that both Con A and LPS induced lymphoid cell proliferation in vitro in group I. There was an increase in activity after stimulation of LPS and its reduction after Con A in group II. This indicates a stimulating effect of flumequine on B lymphocytes. The results of this study are not conclusive as to the positive effect of the drug on the immune system of fish and indicate the need for caution in its use.
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).
Faecal samples from 716 cats from Poland, were examined for lungworm larvae (Metastrongyloidea) by flotation, sedimentation and Baermann techniques between January 2016 and April 2019 year. In total, 1.1% (8/716; CI ± 95% 0.3-1.9) of cats shed lungworm larvae. In the animals examined, infections with Aelurostrongylus abstrusus predominated (7 positive samples), while larvae of Troglostrongylus brevior were detected in only one sample. These invasions were more prevalent in animals under 6 months of age (3.0%) (6/201; CI ± 95%; 0.6-5.4) than in those older than one year (0.4%) (2/515; CI ± 95% 0.0-0.9). Overall, a distinct seasonal pattern was apparent in the detection of infected cats, but annual volatility was not observed. A relatively large proportion of lungworm-infected cats (4 out of 8) had pulmonary syndromes, which indicates that these parasitic diseases should be considered in differential diagnosis of any inflammations of the respiratory system, especially in young animals.
The aim of the study was to determine the prevalence and invasion intensity of gastrointestinal parasites in calves from small and middle-sized farms, with a special focus on invasions of chosen protozoa. The analysis included 150 calves from 2 weeks to 5 months of age. The calves came from 30 individual farms with up to 50 cattle managed in a confined system or confined-pasture system. Three types of farms were established: I: up to 20 heads; II: up to 30 heads, and III: up to 50 heads. The feces samples for the analyses were collected directly from the rectum. Each sample was tested using macroscopic and microscopic methods (the McMaster technique, the standard flotation method and the sedimentation method according to Żarnowski and Josztowa). The numbers of oocysts/cysts/eggs per 1 gram of feces (OPG/CPG/EPG) were established. The feces of 94 calves no older than 8 weeks which exhibited traits of diarrhea were analyzed with Bio-X Cryptosporidium parvum Elisa Kit (Kit for antigenic diagnosis of Cryptosporidium parvum by Elisa in bovine feces). The results were subjected to statistical analysis using the Kruskal-Wallis test. The total prevalence of parasites in all groups was 35.33%. The dominating invasion (26%) was with protozoa belonging to Eimeria (most commonly E. bovis, E. zuerni and E. aubernensis). This was followed by Buxtonella sulcata (6.67%), Cryptosporidium parvum (7.45%; Elisa test), Strongyloides papillosus (4.67%) and gastrointestinal nematodes (2.67%). The fewest calves infected with parasites were in Group I, where only the invasions of protozoa were detected. The parasitic infection rates for group II and III were twice and thrice higher, respectively, than for group I. In Groups II and III, nematodes were found apart from protozoa. In all three groups the dominating invasion was Eimeria spp. (Group I: 20%, II: 24%, III: 34%). The prevalence for B. sulcata, S. papillosus, and gastrointestinal nematodes in the groups was as follows: Group I – 2; 0; 0%; Group II – 8; 8; 0%; Group III – 10; 6; 8%, respectively. In the calves aged up to eleven weeks of life, the dominating invasions were Eimeria spp., Cryptosporidium parvum and S. papillosus, while in the calves of 4-5 months of age, B. sulcata and gastrointestinal nematodes prevailed. The average invasion intensities were as follows: Eimeria spp.: 24414 OPG, B. sulcata: 78 CPG, S. papillosus: 86 EPG, and gastrointestinal nematodes: 138 EPG. In the groups, the results were the following: Eimeria spp.: 94,512 (550-414,000); 271 (100-600); 222 (50-500) OPG., B. sulcata 50; 75 (50-100); 70 (50-100) CPG; S. papillosus 0; 75 (50-100); 90 (50-150) and gastrointestinal nematodes: 0; 0; 138 (50-250) EPG. In the calves from all groups, the dominating invasions were caused by parasites belonging to one taxon (genus), they constituted 90%, 80% and 89%, respectively. The statistical analysis did not reveal statistically significant differences between the management system and invasion intensity of Eimeria spp.
Gastro-intestinal parasites are extremely important pathogens of humans, domestic livestock, and wild animals. Parasitological prevention in wild ruminants was conducted in forests of eastern Poland in early spring from 2009 to 2013. Fenbendazol in a single-dose (5 mg/kg BW) mixed with feed was distributed through forest feeders. Fecal material was collected in the vicinity of the feeders on the day before the treatment (D0) and 14 days after the treatment (D14). To determine the occurrence of gastrointestinal parasites, coproscopic analysis was conducted by the flotation method and McMaster’s method. Parasite species were identified morphologically on the basis of eggs. The fecal samples contained eggs of the nematodes Trichostrongylidae, Chabertidae, Bunostomum, Nematodirus spp.; Trichuris spp.; Strongyloides spp., and an oocyst from the genus Eimeria spp. Nematodes from the Trichostrongylidae family showed the highest prevalence and intensity (prevalence in 2010 = 74.2% [63.7-82.7], EPG in 2009 = 2750) throughout the study. The prevalence of the other taxa varied over the study period: Nematodirus spp. 34.1-77.4%; Trichuris spp. 1.6-17.7%; Strongyloides spp. 0-22.6%, and Eimeria spp. 23.6-51.6%. No statistically significant differences were shown in the occurrence of gastrointestinal parasites before (D0) and after treatment (D14). However, a marked reduction in the prevalence of all gastrointestinal parasites was demonstrated over the five years of the study (treatment efficacy of 66-78% in parasite reduction). There was a significant difference in the EPG of Trichostrongylidae, Chabertidae, Bunostomum (EPG reduction of 71-83%) and Nematodirus spp. (EPG reduction of 70-75%) before and after treatment (U₍₈₎ = 1; P < 0.05; U₍₈₎ = 0; P < 0.05, respectively for family).Changes in the EPG of Trichuris and Strongyloides genus were not significant. In conclusion, it is worth considering parasitic prevention in wild ruminants, which may positively influence animal health, immunity status, and the quality of kill. Moreover, natural deworming in combination with chemical prevention may significantly reduce the contamination of the environmental with parasite eggs.
The aim of the study was to investigate the state of parasitic invasions in flocks of carrier and fancy pigeons in south-western Poland. Coproscopic methods (flotation with saturated NaCl and saccharose, as well as the McMaster method) were used to examine 42 pigeon flocks (18 flocks of fancy pigeons and 24 flocks of carrier pigeons). A total of 210 faeces samples were tested. Prevalence was determined, and average intensity and abundance of gastrointestinal parasites were estimated on the basis of OPG/EPG. Dispersive forms of parasites were found in 78.6% flocks (88.8% of fancy pigeons and 70.8% of carrier pigeons). In the flocks of fancy pigeons most invasions were of mixed character, with statistically significantly high indices of prevalence and abundance. In carrier pigeon flocks, monoinvasions with significantly higher indices of average intensity prevailed, which indicates a high risk of invasion in this group of birds. Eimeriosis was found to be the dominating invasion, occurring in 59.5% of all samples, carrier pigeons – 45.4%, fancy pigeons – 77.7% (59.5% of the flocks), average OPG – 12280, abundance – 7309. Capillariasis: in total – 49% samples, carrier pigeons – 35.8%, fancy pigeons – 66.6% (52.4% of the flocks), average EPG – 3216, abundance – 1577. Ascariasis: in total – 24.3% samples, carrier pigeons – 12.5%, fancy pigeons – 40% (28.6% of the flocks), average EPG – 1953, abundance – 474. Eggs of nematodes belonging to Ornithostrongylus were found in 4.2% of the samples in total: carrier pigeons – 3.3%, fancy pigeons – 5.5% (4.8% of the flocks), average EPG – 488, abundance – 20. Tapeworm eggs were found in 6.2% samples in total, carrier pigeons – 2.5%, fancy pigeons – 11.1% (9.5% of the flocks), average EPG – 607, abundance – 37. The correlation analysis showed relationships between the prevalence and diarrhoea only in the case of tapeworm invasion, no relationship between diarrhoea and the mere fact of infection were found in other invasions. However, a significant correlation was found between the average OPG/EPG of diagnosed parasites (especially Eimeria, Capillaria and Ascaridia) and the observed diarrhoea symptoms.
The aim of this study was to compare the prevalence of selected pathogens in ticks taken from cats and dogs and from vegetation in urban settlements. A study was conducted to estimate the distribution of Anaplasma phagocytophilum and Borrelia burgdorferi in adult Ixodes ricinus (236), Dermacentor reticulatus (237) and Ixodes hexagonus (3) ticks collected from animals in veterinary clinics (184) and from vegetation in urban settlements (292). The most numerous ticks collected from animals were Ixodes ricinus (73.9%), followed by Dermacentor reticulatus (24.5%) and Ixodes hexagonus (1.6%). A total of 65.8% of the ticks collected from vegetation were Dermacentor reticulatus and 30% were Ixodes ricinus. The arthropods removed from the animals were most commonly located around the neck (48.1%) and in the mouth area (17.1%). All ticks were analyzed by molecular techniques. The percentages of ticks positive for Borrelia burgdorferi and Anaplasma phagocytophilum among those collected from animals differed from the corresponding rates for ticks taken from vegetation in the same area. Anaplasma phagocytophilum was more common in ticks collected from vegetation (N = 137, or 47.20%) than in those from animals (N = 12, or 6.6%). Borrelia burgdorferi, as well, was more common in ticks collected from the vegetation (N = 96, or 32.9%) than in those from animals (N = 19, or 10.5%). The DNA of A. phagocytophilum and B. burgdorferi were detected in 30.4% and 22.8% of D. reticulatus ticks, respectively, and in 32.6% and 25.4% of I. ricinus ticks, respectively. The DNA of A. phagocytophilum was also found in one Ixodes hexagonus tick. Single infections were noted in 69 I. ricinus ticks, 56 D. reticulatus ticks and 1 I. hexagonus tick. Coinfections of A. phagocytophilum with B. burgdorferi were detected in 33 (14.0%) I. ricinus ticks and in 29 (12.24%) D. reticulatus ticks. Infected companion animals can form a reservoir for human tick-transmitted infectious agents. The monitoring of the pathogens transmitted by ticks is an important tool in preventing and combating infections transmitted to humans and animals.
The changes in the cattle farming system in Poland observed in the last two decades and related to its evolution into massive scale, specialized farming may have an influence on the occurrence of parasitoses. The study was aimed at showing differences in the prevalence of internal parasites in cattle depending on the herd size, management system and production type. In the period of October to December in 2016 and 2017, the study covered 46 farms with a livestock density from 2 to 160 animals (over 1 year of age), including 25 farms with a confined management system, 12 farms using pastures occasionally and 7 farms with animals using pastures during the whole season. Out of these farms, 36 were oriented towards dairy cattle and 10 to beef cattle. The analytical methods involved flotation, sedimentation and the Baermann technique. In total, 276 feces samples were analyzed. The analysis involved a representative number of samples from each farm, depending on the herd size: from 100% of the animals in the smallest farms to 10% in the largest ones. In total, eleven different taxa of parasites were identified, and their general prevalence was as follows: Eimeria spp. 24.6%, Buxtonella sulcata 25.7%, Strongyloides papillosus 7.6%, gastrointestinal nematodes (Trichostrongylidae, Chabertia, Oesophagostomum) 35.1%, Nematodirus spp. 4.7%, Bunostomum phlebotomum 7.6%, Trichuris spp. 6.2%, Fasciola hepatica 6.9%, Paramphistomum spp 2.5%, Moniezia spp. 2.9%, Dictyocaulus viviparus 2.5%. The forms of parasites were found in samples coming from all studied herds. Invasions of protozoa (Eimeria, Buxtonella) were most commonly found in dairy cattle, in large herds managed in a free stall barn system and in beef cattle, in large herds managed in a pasture system. These herds were also most frequently infected with gastrointestinal nematodes. The invasions of trematodes, tapeworms and pulmonary nematodes were detected only in cattle using pastures, most commonly in large herds.
The aim of the study was to analyze endoparasitic fauna in roe deer of a selected area of south-western Poland using coproscopic studies and postmortem studies of internal organs (lungs, livers and digestive tracts). Microscopic methods included flotation and the McMaster method. In May and June 2015, 53 culled male roe deer were examined. Parasites were found in 96.2% (n = 51, SD = 19.2) of the studied animals, but the invasion intensity was diversified. From 1 to 7 different taxa (families or genera) of parasites were found in each studied animal. Oocysts of Eimeria (3 species (E. capreoli, E. panda, E. rotunda) were found with the following invasion prevalence: 45.28%, low OPG level, in the range of 350-700. In three samples, the OPG amounted to 2800- -4500. Cysts of Buxtonella sulcata 9.4% (CPG in the range of 300-100). Fasciola hepatica (prevalence 3.77%), intensity: 2-3 specimens, Dicrocoelium dendriticum (5.66%), intensity: 2-5 specimens. Moniezia expansa (7.54%), intensity: 3-8 tapeworms. Nematodes from the family Trichostrongylidae (58.49%, genera: Ostertagia, Spiculopteragia, Haemonchus, Trichostrongylus and Nematodiurus from the family Molineidae), low invasion intensity (8-55 nematodes), only in 7 deer intensities of 346-140 nematodes). Capillaria bovis (7.54%) intensity ranging from 2 to 14 nematodes. Oesophagostomum venulosum (15.09%) invasion intensity: 7-23 nematodes, Trichuris globulosa (9.43%), invasion intensity 2-4 nematodes. Dictyocaulus eckerti (11.32%), invasion intensity ranging from 6 to 34 nematodes. Setaria tundra (5.66%) invasion intensity ranging from 1 to 3 nematodes.
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.
