Background: Linguatula serrata is a zoonotic parasite causing Halazoun syndrome in humans. Consumption of raw or semi-cooked infected edible offal induces the infection in human. Objectives: The main objective of this study was to investigate the outbreak and molecular characterization of Linguatula serrata in sheep and goat of Yazd slaughterhouse. Methods: To determine the prevalence and severity of Linguatula serrata, mesenteric lymph nodes of 200 slaughtered sheep and 200 slaughtered goats in the Yazd industrial slaughterhouse were examined. DNA extraction was performed using commercially DNA extraction kit as manufacturers’ protocol. In order to genetic evaluation, the partially 18srRNA gene as a target was amplified using the specific primer pair which was designed by Primer3 software.The PCR product sent for sequencing and the sequence was BLAST. Data were then analyzed using SPSS version 16.0 and by the Pearson correlation test and χ2 at a significance level of 0.01.Results: In the present study, prevalence of the infection of slaughtered goats and sheep was 25.5% and 22.5%, respectively. No statistically significant difference was observed between the prevalence of this parasite in different ages and sexes groups (goats and sheep). The results of genetic evaluation showed no variation between this isolate in comparison with the ones in GenBank. Conclusions: This study was the first report of molecular identification of Linguatula serrate in Iran. Considering high prevalence of infection in domestic animal and lack of knowledge and hygienic practice of the people about consumption of animal offal infection of the people to Linguatula serrata is probable. Therefore, in this context, using appropriate and reliable diagnostic methods for detection of infection in abattoirs as well as educating people on the proper use of animal offal is effective steps to prevent this disease.

Fasciolosis is caused by digenean trematodes of the genus Fasciola. The principal definitive hosts are cattle, sheep and goats. Humans are infected as accidental hosts. Fasciolosis is one of the major neglected tropical diseases and is considered an emerging zoonotic infection. This study was aimed at determining the prevalence of human and domestic animal fasciolosis in selected counties in Kenya. Stool samples for Fasciola diagnosis were collected from humans and domestic animals and transported to the laboratory at Egerton University and processed using sedimentation technique and examined for the presence of eggs. A total of 272 human samples collected were all negative for Fasciola eggs. A total of 582 domestic animals (cattle &#91;46.0%&#93;, sheep &#91;29.9%&#93; and goats &#91;24.1%&#93;) samples collected had overall prevalence of 30.9% for Fasciola infection. There was no significant differences (p > 0.05) between the prevalence of fasciolosis and origin of the animals, sex and season. There was a significant difference (p < 0.05) between the prevalence of fasciolosis and domestic animals, age and body condition. The prevalence of fasciolosis was high in two irrigation schemes which favour the breeding of intermediate host snail and grazing of animals along the irrigation canals where metacercaria of Fasciola parasites could be present on the vegetation. Although human fasciolosis was not detected in this study, the presence of animal fasciolosis can pose public health risk because of its zoonotic nature. Therefore, it is important to introduce measures which would help to reduce the exposure of animals to Fasciola infection.

International audience | Toxoplasma gondii is a major neglected parasitic infection occurring in settings of extreme poverty in Africa. Apart from causing reproductive failure in animals it is also a significant zoonotic concern. The objective of this study was to determine the seroprevalence and associated risk factors of T. gondii infection in cats, chickens, goats, sheep and pigs in the southeast of South Africa, of which little is known. Sera was obtained from 601 domestic animals including 109 cats, 137 chickens, 128 goats, 121 sheep and 106 pigs managed under different production systems in different agro-ecological regions and evaluated by the Toxoreagent, a latex agglutination test for T. gondii antibody detection. Household-level and animal-level data were collected by interviewing animal owners and/or herders using a closed-ended questionnaire. The study revealed an overall farm seroprevalence of 83.33% (125/150 farms) with the highest rate of infection for the parasite found in sheep with 64.46% (78/121), followed by goats with 53.91% (69/128), pigs with 33.96% (36/106), cats with 32.11% (35/109 cats) and chickens with 33.58% (46/137). The risk factors that were found to be statistically significant (p < 0.05) to different species of seropositivites were age, location, climate, animal production system, rodent control, seropositive cat, cat-feed access and cat faecal disposal. The relatively high seroprevalence of T. gondii detected in this region suggests that domestic animals may pose a substantial public health risk through the consumption of T. gondii-infected raw meat as well as via contact with cat faeces.

An analysis of samples originating from domestic and exotic animals from Lower Silesia but also from other parts of Poland was carried out based on research conducted in 2014–2017.

Immunohistochemical studies have become an indispensable element of establishing the correct histopathological diagnosis of poorly differentiated lesions, proving particularly suitable, and occasionally indispensable, for diagnosis of poorly differentiated neoplastic tumours. Knowledge of the mechanism of action and normal reaction of individual proteins is required in selection of the antibody pattern for a given tissue and in evaluation of the obtained results. This paper aims to promote the application of immunohistochemical techniques in routine diagnosis, especially in cases of poorly differentiated or undifferentiated tumours.

Helminths and protozoa are examples of endoparasites that, during their biological cycles, can alternate between free-life stages and parasitic stages in the environment. Pets, such as dogs and cats, live together with men and play an important role in the society; however, these animals may carry a large number of parasites which, besides showing direct pathogenicity to the host, represent risks to the human health, as is the case of parasitic zoonoses. Public areas like parks, gardens, squares and beaches may offer risks to human users since these environments may contain feces deposited by parasitized dogs. The present study  verified the occurrence of helminth eggs and/or protozoan cysts or oocysts in fecal samples collected from sand strips at the beaches Armação do Pântano do Sul, Campeche and Morro das Pedras, in the south of Florianópolis Island, Santa Catarina State (SC), during the summer period. Pet feces were collected in the 2016/2017 summer season, from December 2016 to February 2017. In the Laboratory of Animal Parasitology (CCA-UFSC), fecal samples were processed based on Willis-Mollay flotation technique and Hoffman sedimentation technique. Samples from all three analyzed beaches were positive for the presence of parasites and fecal material was found along the seashore, sites where people walk freely and barefoot. Of 104 fecal samples collected, 45 (43.27%) were positive for one or more parasites. The greatest prevalence was found in Campeche Beach, which had 72.22% positive samples. Ancylostomids were most prevalent, indicating that cutaneous larva migrans is likely to occur in humans. Other parasites such as Trichuris vulpis, Toxocara spp. and Giardia spp. were also detected in coproparasitological analyses. Based on the results, it was concluded that contamination of the beaches in Florianópolis Island, SC, constitutes a public health problem due to the possibility of zoonosis transmission. These results reinforce the importance of establishing health programs for parasite control and educational programs for elucidating the risks of transmission of these zoonoses to the population, as an attempt to reduce environmental contamination risks at beaches of seaside resorts.

Antimicrobial resistance is a global health threat. It has been studied in humans and domestic animals, but there is a lack of data on wild animals. The objective of this study is the elucidation of its patterns in Staphylococcus spp. isolated from wild mammals of the Autonomous Community of Aragón (Spain). A total of 103 mammals (Artiodactyla, Carnivora, Chiroptera, Erinaceomorpha, and Lagomorpha) were studied. A recovery centre provided 32 and hunting 71. Nasal and faecal samples yielded 111 staphylococci, which were identified by matrix-assisted laser desorption/ionization–time of flight mass spectrometry. A susceptibility test to 11 antibiotics was carried out, and statistical analysis was performed. Some differences were detected in bacterial prevalence depending on how the mammal fed. Artiodactyla, mainly hunted, were predisposed to carry coagulase-positive staphylococci. The staphylococci species recovered were resistant to at least two classes of antibiotics, and were disseminated in all of the geographical areas studied. Resistant staphylococci are widely distributed in the wild mammals in the areas of the study, but the resistance quantified in them is lower than that to be expected if the use of antibiotics in farms had a direct influence on the wildlife and its environment. On the other hand, resistance to antibiotics restricted to human use was widely disseminated in various wild animal species.

Introduction: Foxes are a reservoir of parasites that are dangerous to humans. The aim of the study was to determine the parameters associated with the occurrence of tapeworms in red foxes in north-western Poland. Material and Methods: Parasitological sections were taken from 620 red foxes using IST and SCT methods in 18 districts of West Pomerania Province. Results: The extensity of fox infection with tapeworms was 61%. Echinococcus multilocularis, Mesocestoides spp., Dipylidium caninum, and specimens of the genus Taenia were identified. E. multilocularis was found in 11 districts. Mesocestoides spp. demonstrated the highest prevalence (41.3%), while E. multilocularis demonstrated the lowest prevalence (2.9%); however, it infected foxes with the greatest mean intensity (235.6 tapeworms per fox). The most common co-occurrence in a single host organism was observed for Mesocestoides spp. and tapeworms of the genus Taenia; however, no examples were found of coinfection by E. multilocularis and D. caninum. Conclusion: The occurrence of tapeworms in foxes was high in West Pomerania Province and was often higher than observed in previous years. For this reason, the risk of parasite transmission to humans and domestic animals is mounting. The risk of infection is also amplifying due to the growth of the fox population.

This study aimed to determine the numbers, directions, localizations, diameters, morphometric values of the nutrient foramina (NF) in humerus of domestic mammals and to reveal the differences between the right and left humerus in animal species. In the study, a total of 223 humerus, large ruminants (56), small ruminants (60), equidae (29), sus (24), carnivora-dog (42), and carnivora-cat (12), were examined in the Department of Anatomy, Faculty of Veterinary Medicine, Van Yuzuncu Yil University. The numbers, shapes, directions, localization sites and localized surfaces of the NF’s were observed with the naked eye, and recorded. The locations of the NF’s were confirmed by calculating the Foraminal Index (FI). The diameters of the NF’s were measured using 1.2 mm (18 Gauge: G), 0.9 mm (20 G), 0.7 mm (22 G), 0.55 mm (24 G), and 0.1 mm (34 G) needles. In animal species, morphometric measurements were taken such as total length of the humerus (TLH), distance between the NF with the proximal end of the humerus (NFP), distance between the NF with the distal end of the humerus (NFD), FI and performed statistical analysis of the measured values.There was found a single NF in 99% of the examined humerus in the study. In general, it was seen that the NF’s were directed downwards, and located in the middle 1/3 with lower 1/3 segments. NF’s were determined to be localized to the facies caudalis in 100% of sus, in 93% of large ruminants and carnivoradogs, and in 85% of small ruminants; however, in equidae and carnivora-cats were all localized to the margo medialis. According to the statistics, no statistically significant difference (p>0.05) was observed between the right and left humerus NF measurement values in terms of morphometric properties. But only, the diameter of the NF in the small ruminants was statistically significant (p<0.05).It was found that the morphological and morphometric differences of NF’s in right and left humerus of domestic mammals. Moreover, in these animals, it is thought that the study may help veterinary clinicians and surgeons in evaluating of the pathological conditions related to humeral NF and planning of the operative applications to be performed in this region.
