Introduction: The aim of the study was to determine the prevalence of intestinal helminths in red foxes (Vulpes vulpes) and raccoon dogs (Nyctereutes procyonoides) in the Augustów Primeval Forest (north-eastern Poland), with particular regard to zoonotic parasites.Material and Methods: Intestines from 53 raccoon dogs and 66 red foxes were examined with the use of sedimentation and counting technique (SCT). Samples of faeces from 51 red foxes and 50 raccoon dogs were examined with the use of flotation method.Results: Parasitic helminths were found by SCT in 98.5% of red foxes and 96.2% of raccoon dogs. Both species were infected with: Alaria alata (93.9% and 94.3%, respectively), hookworms (68.2% and 83.0%), Apophallus spp. (7.6% and 15.1%), Mesocestoides spp. (57.6% and 24.5%), Taenia spp. (40.9% and 1.9%), and Toxocara/Toxascaris nematodes (33.3% 15.1%). Echinococcus multilocularis was detected only in red foxes (6.1%), but trematodes Echinostomatidae and nematodes Molineus spp. only in raccoon dogs (18.9% and 41.5%, respectively). Additionally, Capillaria spp. eggs were detected by flotation method in 78.4% of foxes and 20.0% of raccoon dogs.Conclusion: The study showed a very high percentage of red foxes and raccoon dogs infected with intestinal helminths in the Augustów Primeval Forest. Moreover, dangerous zoonotic parasites also were found, which should be taken into consideration in the assessment of infection risk for humans in this region.

There are limited data on the efficacy of antiparasitic treatments and husbandry methods to control nematode infections in captive populations of African green monkeys (AGMs), Chlorocebus sabaeus. In faecal egg count (FEC) tests, 10 of the 11 (91%) adult male AGMs captured from the large feral population on the island of St Kitts had evidence of nematode infections, mostly Capillaria (8/11, 73%), Trichuris trichiura (7/11, 64%) and strongylid species (7/11, 64%) specifically (hookworm and Trichostrongylus, 50/50), but also Strongyloides fuelleborni (1/11, 9%). When kept in individual cages with cleaning and feeding regimens to prevent reinfections and treated concurrently with ivermectin (300 µg/kg, given subcutaneously) and albendazole (10 mg/kg, given orally) daily for 3 days, 60% (6/10) of the AGMs were negative at a follow-up FEC at 3 months and by FEC and necropsy at the end of the study 5-8 months later. One monkey appeared to have been reinfected with T. trichiura after being negative by FEC at 3 months post-treatment. Four AGMs were positive for T. trichiura at the 3 month FEC follow-up but were negative at the end of the study after one further treatment regimen. Although initially being cleared of Capillaria following treatment, three AGMs were found to be infected at the end of the study. The ivermectin and albendazole treatment regimen coupled with good husbandry practices to prevent reinfections effectively controlled nematode infections in captive AGMs.

In most countries, poultry are reared by traditional farmers d ue tothe relative minimum capital needed to start off, availability of feed and the fast period of the birds to grow. This research was conducted on turkeys which aims to study the abundance and prevalence of ectoparasites from three localities around Kedah, Malaysia. Atotal of 20 turkeys (eight males and twelve females) were examined for ectoparasites infestation and endoparasites infection.Six species of ectoparasites: five lice and a mite have been discovered. The most prevalent ectoparasite was Menopon gallinae with occurrence of 45%. Other external parasites recorded includeLipeurus caponis and Megninia cubitalis with occurrence of 40%, Menacanthus pallidulus (35%), Goniocotes gallinae (30%) and Chelopistes meleagridis (20%). There was a significant difference between the ectoparasite abundance in Jabatan Perkhidmatan Veterinar and Alor Belat Barat [ANOVA, F(2,17)=6.33, p=0.009]. These lice commonly found in the fluff of the feathers, especially at the neck,abdomen, and wings. Lipeurus caponis was found to have the highest infestation in all male and female turkeys and Menacanthus pallidulus was noted as the less common ectoparasite infesting both the male andfemale turkeys. Endoparasite infection was recorded in two species of parasite eggs of nematodes and protozoa. Oocyst of Eimeria spp. recorded the highest faecal egg count with 7300 epg compared to Capillaria spp. with only 1200 epg. Scavenging and pecking behaviour of turkeys in barn area with unsuitable farm housing environmentwere the major contributing factors to the infestation of ectoparasites as well as endoparasites infection.

Objective: To identify the prevalence of gastrointestinal parasites that affect the backyard poul¬try system in the Savanna region, Department of Sucre, Colombia. Materials and Methods: Fecal samples were collected from 860 native birds, both hens (Gallus domesticus), ducks (Anas platyrhynchos domesticus), and turkeys (Meleagris gallopavo), regardless of age and sex. Samples were processed using direct techniques with ZnSO4 and indirect methods such as modified Sloss. Data were presented as frequencies, and the nonparametric odds ratio test was used for two independent samples. Results: A total of 77.3% (665/860) of the birds were infected with one or more species of gas¬trointestinal parasites. Among the nematodes, Capillaria spp. (45.6%), Ascaridia galli (18.4%), Heterakis gallinarum (59.4%), Syngamus trachea (38.9%), Tetrameres spp. (25.2%), and Strongylus spp. (12.2%) were recorded. The cestodes were Choanotaenia infundibulum (22.6%), Davainea proglottina (42.3%), Raillietina spp. (58.3%), and Hymenolepis spp. (54.7%), while only Eimeria spp. (90%) was recorded as protozoa. Conclusions: The study showed a high incidence of gastrointestinal parasite infestations, the most common species being Hymenolepis spp., Eimeria spp., Raillietina spp., and Heterakis gallinarum.

Investigation of frequency of occurrence and manifestations of liver pathology of swine during the postmortem examination at meat packing plant of the Republic of Belarus was realized. Data analysis of reports of postmortem veterinary-sanitary examination gathered from two leasing national meat packing plants showed that out of 236187 of evaluated swine carcasses and organs in 40860 (17,3%) of cases there were registered different liver pathologies. Among the total number of liver pathologies in 5721 cases (14%) there were stated liver pathologies caused by invasive diseases (echinococcus disease (Echinococcus granulosus) – 1,5%; cysticercosis – 0,2%; migration traces of ascarid larva - 12,3%), and 31830 cases (86%) were caused by noncontagious diseases. The highest percentage among noncontagious liver diseases was stated for dystrophic organ changes (83,6%); the other 17,2% were caused by fibroid induration. During the morphological liver analysis there were stated the dystrophic and necrotic changes in fractions with the profound disturbance of blood circulation. At the same there was noted the disturbance of the whole fraction stricture, acute capillary engorgement in the central and peripheral zones
