Endoparasites of horses from the Formiga city, located in center-west region of the state of Minas Gerais, Brazil

With the aim of studying the endoparasite fauna of horses from the Formiga city, located in center-west region of the state of Minas Gerais, 25 animals that were naturally infected with helminths were evaluated. By means of parasitological necropsies, different endoparasites were found. The subfamily Cyathostominae presented the highest incidence, followed by Trichostrongylus axei, Oxyuris equi, Triodontophorus serratus, Strongyloides westeri, Strongylus edentatus, Habronema muscae, Parascaris equorum, Probstmayria vivipara, Strongylus vulgaris, Gasterophilus nasalis, Anoplocephala magna and Anoplocephala perfoliata. In the present study, if the species Probstmayria vivipara was not considered in the prevalence, the frequency of Cyathostominae was equivalent to 94.85%. The results obtained in this study allowed us to detect and identify different species of helminths in horses, and confirmed the high incidence of nematodes belonging to the subfamily Cyathostominae in the center-west region of Minas Gerais.

Abstract The present research is a continuation of studies conducted periodically over 40 years on transmission of natural infections of internal parasites in the same horse herd on pasture (Field 10) on a farm in Central Kentucky. It included 12 mixed light horse foals born in 2013 and euthanatized between July, 2013 and April, 2014 for collection of internal parasites. Parasites found: Gasterophilus intestinalis, Strongyloides westeri, Parascaris equorum, Anoplocephala perfoliata, small strongyles (cyathostomes), Strongylus vulgaris, Strongylus edentatus and Thelazia lacrymalis. Prevalence generally was related to age of the foals. Overall prevalence and number of specimens were lower than in earlier studies except for P. equorum. There were 15 species (much fewer than previously) of small strongyles found and recorded by location in the large intestines. All stages of small strongyles encysted in the mucosa of the large intestine were recovered by artificial digestion and in significantly lower numbers in older foals

The article provides information about the new preparation Iverpradag, developed by the firm "Gudratli lukman" (Turkmenistan), which is being tested in Russian Federation and Turkmenistan, intended for the prevention and treatment of parasitosis in horses. The active principle of the developed preparation is widely known and very effective ivermectin and praziquantel (in complex). Studies conducted in Russia and Turkmenistan showed high effectiveness of the drug against nematodes including Delafondia vulgaris, Alfortia edentatus, Dictyocaulus arnfieldi, Parascaris equorum, Strongylus equinus, Strongyloides westeri, Setaria equina, and cestode, including Anoplocephala magna, Anoplocephala perfoliata and Paranoplocephala mamillana, as well as against gastric larvae (Gastrophilus spp.) parasitizing in horses. The conducted studies showed high efficiency of the drug Iverpradag in the form of paste when applied at the rate of 1 dose (0,9 ml) per 100 kg of body weight.

The aim of the field study performed in 2006 was to investigate the occurrence and distribution of intestinal helminths in horses based on pre-treatment faecal egg counts. In total, 948 horses bred on 37 farms were tested. Thirty six (97.2%) farms tested were positive for cyathostomins; horses in 9 (24.3%), 6 (16.2%) and 1 (2.7%) different herds tested were positive for Parascaris equorum, Anoplocephala perfoliata and Strongyloides westeri, respectively. In 21 herds, 344 horses with values exceeding 100 eggs per gram were included in the trial for the presence of drug resistant cyathostomins by a faecal egg count reduction test. Horses were treated orally with recommended doses of fenbendazole and ivermectin. Resistance to fenbendazole was detected on 20 farms (95.24%) with values of faecal egg count reduction test ranging from 0 to 90%. Ivermectin remained effective in all tested herds with the value of faecal egg count reduction test 96–100%. In autumn 2008, 178 horses on 10 farms were examined. Of these, only seven horses tested were negative for cyathostomins. One farm was tested positively for Anoplocephala perfoliata, and one for Parascaris equorum. In spring 2009, six farms were examined, four of which were the same farms as in 2006. We found a decreased number of eggs per gram in all horses, but an increase in benzimidazole resistance, which was found in 5 farms out of 6 (faecal egg count reduction test 15.2–84.6%). This is the first wide survey in horses from the Czech Republic. Based on this study, we can conclude that benzimidazole resistant cyathostomins in horses are widespread but ivermectin is still fully effective.

Abstract The study was performed to investigate the gastrointestinal parasite fauna using the method of diagnostic deworming in own modification in 29 Polish primitive horses (Equus caballus) from the Roztocze National Park, south-east of Poland. The parasite community was comprised of 35 species represented by three nematode families (Strongylidae, Ascaridae, Habronematidae), one cestode family (Anoplocephalidae) and larvae of insects from the family Gasterophilidae (Diptera). Strongylidae being 100 % prevalent was represented by 31 species from the subfamily Strongylinae (6 species) and Cyathostominae (25 species). Parascaris equorum was recorded in 48.3 %, Habronema muscae in 55.2 %, tapeworms (Anoplocephala perfoliata) in 24.1 % and Gasterophilus intestinalis larvae in 41.4 % of horses surveyed. The present results showed high prevalence of pathogenic intestinal parasites, which create the risk of health problems for horses living free in the reserve as well as stabled horses, when rarely treated.

Summary An extensive analysis of the relationship between age, sex, and different types of management strategies relative to the gastrointestinal parasite community of Polish primitive horses was performed on 124 horses maintained in nine farms from four regions of Poland. The horses (96 females and 28 males) were housed in three types of management strategies: stabled (ST), free-ranging (FR) and semi-free (SF). These horses also were divided into three age groups: <3 years, 3 – 10 years and >10 years old. The gastrointestinal parasites were collected following deworming of all horses with anthelmintics containing the macrocyclic lactones and praziquantel. Totally, 66,192 parasite specimens were collected and identified. The analysis of dependence of horse infection with intestinal nematodes using sex, age and management strategies demonstrated that females had significantly heavier infections of strongylids. Young horses (<3 years old) had higher infections of Parascaris equorum and Strongyloides westeri. Free ranging horses were more infected with strongylids, Oxyuris equi and Gasterophilus intestinalis. Thirty-five nematode species, one cestode and one species of the botfly larvae of Gasterophilus were found. Diagnostic deworming examination revealed presence of Parascaris equorum in 27.4 %, Oxyuris equi in 38.7 %, Habronema muscae in 16.9 %, Anoplocephala perfoliata in 42.7 % and Gasterophilus intestinalis in 46.8% in the Polish primitive horses examined. Strongyloides westeri presence was confirmed only by fecal samples examination; threadworms were not observed in these horses after deworming. In the strongylid community, 31 species (6 of subfamily Strongylinae and 25 of Cyathostominae) were found. Significant differences in prevalence of separate strongylid species, or their proportions in the communities were not observed between females and males, or between age groups (p > 0.05). The highest species diversity (n=30 or 31) was observed in the FR horses, the lowest (n=15) – in ST horses. The FR horses had higher prevalence and proportion of large strongyles in the community, in comparison to SF or ST horses (p < 0.05).
