Abstract Helminth and protozoan infections are responsible for important diseases in grazing sheep, which can be especially threatening in an autochthonous breed at risk of extinction like the Churra Galega Mirandesa Portuguese sheep breed. The aim of the present study was to determine the diversity, prevalence and burden of gastrointestinal parasites in these sheep and to assess the effects of deworming practices, cohabiting animals on the farm and feed management. Coprological qualitative and quantitative analysis (flotation, natural sedimentation and McMaster method) were used to identify and quantify gastrointestinal parasites and a questionnaire was designed and applied. A total of 512 faecal samples were collected from 49 flocks, and 49 replies to the questionnaire were received. Parasites were identified in 100% of the flocks, and in 97% of the samples. The genera or species that have been morphologically identified were: strongyle-type, Nematodirus spp., Skrjabinema spp., Moniezia expansa, Moniezia benedeni, Trichuris spp., Capillaria spp., Eimeria spp., Dicrocoelium spp. and Fasciola hepatica. This is the first report in Portugal of Skrjabinema spp. The burden of parasites’ oocysts and eggs per gram in faecal samples ranged, respectively, from 50 to 17,550 for Eimeria spp., and from 50 to 6250 for strongyle-type eggs. Factors affecting parasitic infections were evaluated using a multivariate logistic regression. Grazing time and a lack of anthelmintic treatment were positively associated with Nematodirus spp. infection. This study showed that there is a high prevalence and diversity of gastrointestinal parasites in the Churra Galega Mirandesa sheep breed.

This study was conducted with the aim of determining the dry season (January-May, 2018) prevalence of gastrointestinal parasites in special breeds of ruminants in Sokoto Metropolis. A total of 100, 85 and 75 faecal samples were collected from Sudanese breed of Sheep, WAD/Sahel Goats and Friesian Cattle respectively. Faecal samples were examined using standard parasitological techniques (Simple flotation and Centrifugal sedimentation). For the Sheep, a total of 51 samples were positive for presence of gastrointestinal parasites. Male animals have higher prevalence (52.9%) than their female (47.1%) counterparts. The major parasites observed were Eimeria and Strongyles with prevalence of (64.71%), while the least observed parasites were mixed infections (35.29%). From the total of 85 goat faecal samples examined, an overall prevalence of 54.7% was observed. The prevalence rates for Strongyle, Eimeria and mixed infections were 57.5%, 34.0% and 8.5% respectively. The prevalence was more in males than in the females. Strongyleeggs were more, compared to other helminthes eggs. For the Friesian Cattle, sixty (60) samples out of 75 samples analyzed were positive for either Strongyleeggs or Eimeria (oocyst) infection or both (mixed) constituting about 80% prevalence. Forty-two (70%) samples were positive for Strongyle eggs, 14 (23.3%) for Eimeria oocyst and 4 (6.7%) for mixed infection of both. From the overall prevalence, female had a high prevalence of 34(56.7%) than male cattle 26(43.3%). Based on the results of the present findings, it was concluded that gastrointestinal parasitic infections also occur during the dry season in Sokoto which may be as a result of carry-over of infection during the succeeding rainy season.

Abstract Background Little information about the prevalence of gastrointestinal parasites in yaks (Bos grunniens) in northwest China is available. Therefore, the objective of the study was to quantify faecal egg counts of gastrointestinal parasites (helminths and coccidia) in free-range yaks from Gannan Tibetan Autonomous Prefecture, Gansu Province, Northwest China. Results Parasites were detected in 290 of 733 (39.56%) faecal samples. The results showed that Strongylidae, Trichuris spp. and Eimeria spp. were detected all year round, Strongyloides papillosus was detected in autumn and summer, and Nematodirus spp. was detected in both autumn and spring. In contrast, Fasciola spp. was only detected in spring. The prevalence rates of parasitic infections in different seasons were significantly different. Conclusions To our knowledge, this is the first investigation of gastrointestinal parasites in yaks (Bos grunniens) in Gansu, China. The results demonstrated a high prevalence of gastrointestinal parasitic infections, specifically GN infections, in yaks in GTAP and these infections can cause economic losses to the local cattle industry.

Abstract Gastrointestinal parasites are involved in the health and wellbeing of cats and some of them, due to their zoonotic character represent a problem for the public health. This study aimed to assess the prevalence of parasitic infections in cats with digestive symptoms. Faecal samples collected from 137 cats were analysed by the flotation method using sodium chloride saturated solution. The overall prevalence of gastrointestinal (GI) parasites was 56.6%. GI parasites were significantly (p=0.005) more common in cats with digestive symptoms (69.8%) than in clinically healthy ones (23.0%). Toxocara cati (40.2%) was the most frequently identified GI parasite, followed by Cystoisospora spp. (10.2%), Ancylostoma tubaeforme (3.7%), Taenia spp. (2.2), Giardia duodenalis (2.2%), and Toxoplasma gondii-like oocysts (0.7%). T. cati (53.3%, p<0.0001) and Cystoisospora spp. (15.6%, p<0.001) were significantly more frequently diagnosed in cats with digestive symptoms. Lack of deworming in the last three months (OR: 15.9), outdoor access (OR: 13.8), the presence of digestive symptoms (OR: 5.4), and young age (OR: 4.2) were identified as risk factors for T. cati infection by logistic regression analysis. Regardless of the age, symptoms like vomiting, diarrhoea, and inappetence were positively associated with T. cati.

This study investigated the overall prevalence of Haemonchus contortus infection in sheep and goats from five purposively selected subdivisions (sectors) of Nyagatare district from January to December 2014, after a high prevalence of gastrointestinal parasites and generalized poor productivity was reported in small ruminants in some districts of Rwanda. Faecal egg counts (FEC) were performed using the Modified Wisconsin Sugar Floatation method and the Fluorescent-labeled peanut-lectin agglutination test while enumerations, as log (FEC), were done using the modified McMaster method. The overall prevalence of H. contortus infection in sheep and goats was 75.7% (n=949). The overall prevalence of H. contortus infection in sheep (83.4%, n=314) was higher than in goats (71.8%, n=635) (Odds Ratio [OR] 1.98, 95% Confidence Interval [CI]: 1.40-2.79, and p≤0.001). The prevalence of H. contortus infection in female goats (74.2%) was higher than in male goats (64.3%) (OR 1.60, 95% CI: 1.09-2.36, and p=0.01). The prevalence of H. contortus infection in goats from Nyagatare was higher than in goats from Matimba (OR 3.25, 95% CI: 1.76-5.99, and p≤0.001) and from Katabagemu (OR 3.67, 95% CI: 2.04-6.59, and p≤0.001). The prevalence of H. contortus infection in goats from Karangazi was higher than in goats from Matimba (OR 4.72, 95% CI: 2.40-9.28, and p≤0.001). The overall mean monthly log (FEC) for H. contortus in sheep and goats were highest in April (18.9±0.2 and 14.05±0.1, respectively) and October (19.25± 0.2 and 13.75±0.1, respectively). Though, overall, sheep in Nyagatare district were at greater risk of H. contortus infection and goats from Nyagatare and Karangazi sectors were paradoxically at greater risk of H. contortus infection. It was also apparent that young female goats were at greater risk of H. contortus infection than young male goats. H. contortus infection is endemic in small ruminants in Nyagatare district and possibly other districts in Rwanda. Targeted selective treatment (TST) using FAMACHA with emphasis on low-lying swampy pastures and appropriate anthelmintic drugs may be the most economically viable solution in the short term. In the long term breeding of H. contortus resistant small ruminants and strategic grazing using the concept of refugia may bring about considerable relief from H. contortus infection in Nyagatare district, in particular, and Rwanda at large.

Abstract. Prevalence of gastrointestinal parasites was studied in 106 heifers imported to Poland from the Netherlands. Prevalence of gastrointestinal nematodes and Eimeria protozoans was determined from coproscopic examinations using Willis-Schlaf flotation. The species composition of coccidia was determined from morphological characters and the time of oocyst sporulation. Fluke liver eggs were detected by decantation. The study showed the mean prevalence of Eimeria protozoans in the heifers imported from the Netherlands to Poland to be 17.92 %; the mean prevalences of Cryptosporidium sp. (11.32 %), gastrointestinal nematodes (55.66 %) and Fasciola hepatica (32.08 %), respectively. The following 6 coccidia species were isolated from faecal samples: E. bovis, E. aubernensis, E. ellipsoidalis, E. subspherica, E. zürni, and E. brasiliensis. The prevalence of gastrointestinal parasites in the cattle imported from the Netherlands to Poland was very high, therefore it is purposeful to mandatorily examine the imported cattle for the presence of those parasites.

Abstract Coprological analysis was performed to check the presence and previlance of gastrointestinal parasites. One hundred seventy six bovine faecal samples were studied. The study reported the presence of parasitic stages of Balantidium coli, Buxtonella sulcata, Trichostrongylus spp., Toxocara vitulorum, Fasciola spp., Strongyloid spp., and Paraamphistomum spp. 43.51 % (n = 108) faecal samples from Gir cattle (Bos primigenius indicus) were positive for Gastrointestinal parasitic infections. and 36.76 % (n = 68) faecal samples from Jaffrabadi Buffaloes (Bubalus bubalis) were positive for Gastrointestinal parasitic infections. In Cattle Balantidium coli was found highest (20.37 %) and in Buffaloes Buxtonella sulcata was found highest (8.82%). the highest incidence was recorded during august for both cattle (6.48 %) and buffalo (7.35 %). Gastrointestinalparasitic infections in claves (< 12 Months) was higher than older (> 60 Months) and adult animals (12-60 Months). Season wise gastrointestinal parasitic infections in cattle were reported maximum (23.15 %) during monsoon. Maximum prevalence in buffalo was reported during Monsoon (16.18 %). similarly, females recorded higher infection rates than malesfor both cattle and buffalo.

Background: It is make clear that salt and pepper retinal lesion (SPRL) has subsequently associated with the infection with Giardia lamblia (G. lamblia). However, little is known regarding prevalence of SPRL among patients suffered from parasitic infections in the world. Objective: The aim of this study was to determine the prevalence of SPRL among patients with intestinal protozoan infections, for the first time, in Sari, northern Iran. Methods: In this case-control study a total of 150 subjects participated: 75 were in patients group diagnosed to have intestinal parasite, and 75 in control group without any intestinal infection. Fecal samples were obtained from all participants and examined with wet mount and formalin-ether methods. The retina of both groups was examined by an ophthalmologist. Results: Overall, salt and pepper retinal changes were diagnosed in 12 (16 %) patients with at least one parasitic infection (7 females and 5 males). G. lamblia was diagnosed in 6 subjects (50%), Blastocystis hominis in 5 (41.6%), and Entamoeba coli in 1 (8.3 %). Most of the patients (58.3%) had a mild infection. Bilateral retina involvement was observed in 75% of the patients. Furthermore, macula involvement was observed in 91.7 % with SPRL. Conclusion: Our findings indicated the relatively high prevalence of SPRL in subjects with giardiasis and blastocystosis. It can be concluded that not only G. lamblia but also B. hominis can cause SPRL in Sari, Iran. Further studies are needed to find other etiologic parasites able to cause retinal damages.

This experiment was carried out to determine the overall prevalence of pigeon diseases and especially emphasized on prevalence of parasitic diseases in study areas. During this study 45 farms were selected which have &gt;20 pair of pigeon for commercial and &gt;10 pair pigeon for traditional farm in the three study area namely Rajshahi, Natore and Pabna district of Bangladesh. The data were collected from different farm within the study area through a questionnaire and interview schedule with the farm owners. During one year of study period a total Out of 3677 pigeon, positive case in cage of external parasites were 722 and internal parasite positives 114 from 263 fecal sample. The overall prevalence of gastrointestinal and external parasites in pigeon at northern Bangladesh is obtained. The infestation of lice Columbaecula columbae and fly Pseudolynchia canariensis were observed 18.08% and 1.55% respectively. The present study found two species of ectoparasites lice and fly. Diversity of ectoparasite in birds infestation may be depend on many factors, which may include home range, behavior, size and roosting habit of the host. The overall prevalence of gastrointestinal parasites in pigeon are founded that 43.34% in research area. Specific incidence was 22.81% in Ascariasis, 18.63% in Capilariasis and 1.90% in Raillietina parasite in pigeon. Ascaridia colombae is one of the most common (22.81%) helminth species in pigeons in this study. The effect of breed of pigeon observed in present studies the highest in indigenous (63.47%) and lowest exotic (36%) prevalence of gastrointestinal parasite was observed. The specific percentages of Ascariasis, Capilariasis and Raillatina gastrointestinal parasites of pigeon were found 20% &amp; 31.74%; 14% &amp; 30.15% and 2% &amp; 1.58% in exotic &amp; indigenous breed, respectively. In the present study, there is a relation between the occurrence of gastrointestinal parasitic infections with the age of the pigeons which showed that high prevalence in adults (50%) and compare to young (22.22%). but it was statistically significant (P&gt;0.05). In relation with farming system the gastrointestinal parasitic incidence of pigeon was observed in modern and tradition farming system, the highest incidence was 71.16% in traditional &amp; lowest 31.14% in modern farming. When observed specifically in Ascariasis, Capillariasis &amp; Raillietina were 16.39% &amp; 37.41%; 13.11% &amp; 31.25% and 1.63% &amp; 2.5% in modern &amp; traditional, respectively. The effect of regions on the prevalence of gastrointestinal parasites in pigeon was observed in Pabna (68.32%), Natore (57.84%) and Rajshahi (33.33%). The specific percentages of Ascariasis, Capilariasis and Raillatina gastrointestinal parasites of pigeon were 18.18%, 33.33% &amp; 26.31%; 14.54%, 33.33% &amp; 23.38% and 0.606%, 1.66% &amp; 7.89% in Rajshahi, Pabna and Natore, respectively.

This study was conducted in order to determine the presence of parasitic infections of the Greek buffalo (Bubalus bubalis) in the Prefecture of Serres, Northern Greece. During the period from February to October 2014, faecal samples from 110 buffaloes of the Greek buffalo breed (Bubalus bubalis), from 9 farms located in proximity to Lake Kerkini, in the Prefecture of Serres, Northern Greece, were examined, in order to find reproductive elements of parasites. Out of 110 faecal samples examined, 102 (92.73%) were found infected with reproductive elements (eggs, larvae, cysts and oocysts) of parasites. Specifically, the parasites found were: Eimeria spp. (40%), Entamoeba bovis (16.36%), Paramphistomum cervi (10%), Fasciola hepatica (16.36%), Dicrocoelium dendriticum (28.18%), Moniezia benedeni (27.27%), Toxocara vitulorum (11.82%), Strongylida (gastrointestinal nematodes) (31.82%) and lungworms (28.18%). The present study appears to be the first report of the detection of lungworms in buffaloes, in Greece.

Abstract The overall goal of this study was to estimate the prevalence of gastrointestinal (GI) parasites in dogs in the city of Villahermosa in Tabasco, Mexico. The study population consisted of 302 owned dogs that had limited access to public areas. A fecal sample was collected from each animal and examined for GI parasites by conventional macroscopic analysis and centrifugal flotation. Fecal samples from 80 (26.5%) dogs contained GI parasites. Of these, 58 (19.2%) were positive for helminths and 22 (7.3%) were positive for protozoan parasites. At least seven parasitic species were identified. The most common parasite was Ancylostoma caninum which was detected in 48 (15.9%) dogs. Other parasites detected on multiple occasions were Cystoisospora spp. (n = 19), Toxocara canis (n = 7) and Giardia spp. (n = 3). Three additional parasites, Dipylidium caninum, Trichuris vulpis and Uncinaria spp., were each detected in a single dog. No mixed parasitic infections were identified. In summary, we report a moderately high prevalence of GI parasites in owned dogs in Villahermosa, Tabasco. Several parasitic species identified in this study are recognized zoonotic pathogens which illustrates the important need to routinely monitor and treat dogs that live in close proximity to humans for parasitic infections.
