Abstract
Gastrointestinal (GIT) parasites cause sickness and mortality in working donkeys, reducing their productivity. A cross-sectional study was done in the Damot Gale district of southern Ethiopia from November 2020 to June 2021 to determine the frequency of donkey GIT nematode parasite infection and to examine its related risk factors. Overall, 514 simple randomly selected donkeys from peasant associations were sampled for the coprological examination of gastrointestinal nematode infection. The flotation technique was employed to identify parasite eggs in feces. The total prevalence of parasitic gastrointestinal nematodes was 71.79% (95% CI: 67.73-75.52). The most prevalent nematodes were Strongyles (37.74%), Parascaris equorum (11.28%), Strongyloides (7.20%), and combined infections of Strongyles and Parascaris (14.01%) and Strongyles and Strongyloides (1.56%). The association between the prevalence of parasitic GIT nematode infections and body conditions score was statistically significant (p < 0.05). Comparatively, donkeys with semi-intensified systems were five times (OR = 5.36) and those with medium body condition were twice (OR = 1.94) had a higher risk of infection than donkeys with intensive systems and good body condition scores, respectively. In conclusion, the current study indicated that gastrointestinal nematode parasites of donkeys are highly prevalent in the study area. Thus, regular deworming, proper housing, and feeding management were recommended to improve the health and productivity of donkeys in the research area.

Abstract
In June 2022, at the XXXII Conference of the Italian Society of Parasitology, the parallels of the main endoparasitic infections of horses and donkeys were discussed. Although these 2 species are genetically different, they can be challenged by a similar range of parasites (i.e. small and large strongyles, and Parascaris spp.). Although equids can demonstrate some level of resilience to parasites, they have quite distinct helminth biodiversity, distribution and intensity among different geographical locations and breeds. Heavily infected donkeys may show fewer clinical signs than horses. Although parasite control is primarily provided to horses, we consider that there may be a risk of drug-resistance parasitic infection through passive infection in donkeys when sharing the same pasture areas. Knowing the possible lack of drug efficacy (<90 or 80%), it is advocated the use of selective treatment for both species based on fecal egg counts. Adult horses should receive treatment when the threshold exceeds 200–500 eggs per gram (EPG) of small strongyles. Moreover, considering that there are no precise indications in donkeys, a value >300 EPG may be a safe recommendation. We have highlighted the main points of the discussion including the dynamics of helminth infections between the 2 species.

Abstract
We performed this review to determine the weighted prevalence of equids parasitic infections in Ethiopia. Article searches on parasites of equids were conducted using PubMed, PubMed Central, Google Scholar, Science Direct, Web of Sciences, Scopus, AJOLs and Research Gate. A random effects model was used to estimate the weighted prevalence and to study heterogeneity. The primary searches generated, 3082 potential studies, of which 66 reports met the inclusion criteria and were included in the meta-analysis. There were 32 reports involving two or more equids species, eighteen on donkeys, and sixteen on horses. Moreover, fifty of the reports mentioned helminth infections in equids, thirteen on protozoans, and three on ectoparasites. The estimated weighted prevalence of parasitic infections in equids was 58.3% (95% CI 50.8-65.4%, I2 = 99%). Helminths were the most prevalent parasites in equids, accounting for 77.1% (95% CI 71.4%, 82%, I2 = 98.5%), followed by ectoparasites at 35.4% (95% CI 33.4-37.52%, I2 = 88.2%) and haemoparasites (protozoans) at 10.84% (95% CI 6.6%, 17.3%, I2 = 98.1%). Furthermore, with a prevalence of 82.3% (95% CI 75.9-87.3%, I2 = 97.4%), donkeys were the most affected equids with helminth parasites. From the reports, we found forty-three species of helminth parasites affecting equids, including thirty-four nematode species (Strongylus, Cyathostomum, Coronocyclus, Cylicocyclus, Cylicostephanus, Trichostrongylus, Oesophagodontus, Strongyloides, Triodontophorus, Gyalocephalus, Poteriostomum, Dictyocaulus, Oxyuris, Habronema, Draschia, Parascaris, Setaria, and Probstmayria species), three trematodes (two Fasciola and one Gastrodiscus species), three cestodes (two Anoplocephala and one Anoplocephaloides species) and three botfly larvae (one Rhinoestrus and two Gasterophilus species). Trypanosoma species (T. congolense, T. vivax, T. brucei, T. equiperdum, and T. evansi), piroplasms (Theileria equi and Babesia caballi), and Eimeria species have also been reported to affect equids. Ticks (Amblyomma variegatum, A. gemma, Rhipicephalus decoloratus, R. evertisi evertisi, R. pulchellus, R. muhsame, R. sanguineus, Hyalomma rufipes, and Hy. truncatum) and lice (Bovicola equi and Haematopinus asini) were the ectoparasites recorded to affect equids. The risk of publication bias across studies was likely to be high due to differences in publication year and diagnostic techniques. In conclusion, parasitic infections of equids are common in Ethiopia and are caused by a variety of parasite species, putting the performance and well-being of these packing animals at risk. Therefore, more research is needed to identify infection risk factors and raise awareness of the consequences of parasitism in order to provide strategies to mitigate the problems in equids.

Abstract
Abstract
Background: Intestinal nematode parasites of equines have emerged as a pressing and urgent challenge due to their significant impact on the health and performance of these animals worldwide; therefore, implementing a deworming regimen has become vital to keeping a horse's parasite load at an acceptable level. Thus, the current study aimed to estimate the prevalence of nematodes infection , associated risk factors and evaluate the chemotherapeutic efficacy of different anthelmintic drugs by enrolling 195 fecal matter samples of working equines using flotation concentration techniques. Equines treatment were divided into four groups; Group 1 standard treatment (Albendazole orally), Group 2 intervention treatment (Doramectin injection), Group 3 intervention treatment (combination of Albendazole and Doramectin), and Group 4 was left untreated as a positive control.
Results: The overall prevalence of intestinal nematode parasites in working equines was 70.25%. The recovered nematodes were Strongylus species, with 87.17% followed by Parascaris equorum 30.76%, and Oxyuris equi was 12.82%. Concerning treatment efficacy, the highest cure rate was among Group 3 (77.14%), followed by Group 2 (68.57%) and Group 1 (40%), but the difference between Groups 2 and 3 is statistically insignificant. Interestingly, the effect of Doramectin injection is highly significant than other, especially for the reduction of Strongylus spp. and Parascaris equorum eggs according to Cohen's D test.
Conclusions: Translating such a potent combination of drugs into endemic areas will provide significant support for deworming and control programs against intestinal parasites of equines, especially those in the migratory phase, more than Albendazole alone, which has poor absorption as it requires a full stomach during administration.

Abstract
Parasitic infection is one of the major problems in equines which negatively influence their health. It hinders working performance of equines. This study was conducted to evaluate donkey owners' knowledge and control measures on prevalence of gastrointestinal parasites (GIPs) in three agro-ecological zones (AEZs) of Maseru district. A total of 144 donkey owners were selected for individual interviews through a stratified random sampling. Descriptive statistics and chi-square tests were used to analyze data. The significance (p <0.05) of different AEZs was tested using a post-hoc cell-wise adjusted standardized residual analysis. Majority of donkey owners were familiar with the GIPs especially nematodes as it seemed to be the most occurring, but there was no significant effect (p > 0.05) across the AEZs. The adult donkeys were mostly susceptible to different GIPs according to respondents and severe infection was experienced in summer and winter. Donkeys were dewormed seasonally using anthelmintics with inappropriate weighing instruments to establish the dosage, however, chi-square test pointed out the significance (p = 0.004) effect between types of medication used across the AEZs. Donkeys were kept in non-roofed stables that were not cleaned regularly hence, these compromised their welfare. However, communal grazing shared by different livestock species was the main source of animal feeding though it was found to be the major source of GIPs. Therefore, there is a need to equip them on the proper skills to improve on their management practices and the behaviour of parasites in different areas. This will help donkey owners adhere to appropriate control and prevention strategies.

Abstract
Parasitic infections can cause a variety of respiratory, intestinal, and other problems in horses, as well as contribute to some performance issues. A cross-sectional study was undertaken in and around Bekoji, South Eastern Ethiopia, from November 2020 to June 2021 to identify species and evaluate the prevalence of gastrointestinal parasites in donkeys and horses, using direct fecal smear, floatation methods, and larval cultures. In this study, the overall prevalence of gastrointestinal nematode parasites was 94.5% (363 out of 384), with donkeys accounting for 95.8% and horses accounting for 90.5%. The coprological study indicated that an overall prevalence of gastrointestinal nematode parasites was 87%, 8.3%, 2.5%, 1.4%, and 0.8% for mixed parasite infection, nonmigratory strongylids, migratory strongylids, Parascaris equorum, and Oxyuris equi, respectively. Among mixed infections, nonmigratory strongylids+migratory strongylids (51.5%) occurred most frequently. The odds of male horses being infected by GIT nematodes were 1.59 times higher than male donkeys. Horses which have poor body condition were 2.94 times more infected than donkeys. The odds of old-aged donkeys were 3.11 times more infected than horses. A statistically significant difference (p < 0.05) was observed in the prevalence of gastrointestinal nematodes with species and body conditions of the animals. However, no statistically significant difference (p > 0.05) was seen in the prevalence of gastrointestinal nematode parasites between the sex and age of the Equidae. The mean fecal egg count of nematodes revealed that horses (1364.4 ± 483.5) had a more severe infection than donkeys with a statistically significant difference (p < 0.05). The current study determined there was a high prevalence of gastrointestinal nematode parasites in Equidae. Regular deworming, improved housing and nutrition management systems, increased animal owner awareness, and prevention techniques should all be undertaken to minimize the disease's economic burden in the area.

Abstract
Introduction Gastrointestinal helminth parasite infection is a major influencing factor against the profitability of working equines all over the world. Methods This cross-sectional study was conducted in the Hosaena district to investigate the prevalence and the potential risk factors of strongyle infection. To address this, 384 equines; donkeys (n = 208), and horses (n = 176) were randomly selected for the coprological examination to identify strongyle eggs using the floatation technique. Results The study revealed that the overall prevalence of strongyle infection in the Hosaena district was 54.2% and the respective prevalence was 59.1% and 48.2.0% in donkeys and horses, respectively. Strongyles' infection rates in equines were 56.3%, 53.2%, and 56.6% in young, adult, and old animals, respectively, while the rates were 52.8% and 57.1% in male and female animals. Equids with a good body condition were highly prone to strongyle infection than equines with poor and medium body condition, and equids used for transport and packing, cart pulling, and no purpose were highly infected than those used for packing and transport purposes. A significant variation (P< 0.05) was shown in the statistical analysis between the equines and the prevalence of strongyle infection. However, the occurrence of strongyle infection was not significantly (P>0.05) associated with age, sex, and body condition score of equines. Conclusion Hence, strongyles infection is widely distributed in equines in the study area. Further research, including broad sample sizes of gastrointestinal nematodes in all equines, should therefore be recommended for strategic prevention and control measures in order to understand the severity of the disease.

Abstract
The aims of this study were to determine the prevalence of gastrointestinal nematodes (GIN) in horses, donkeys and mules and its associations with age, sex and climatic factors (derived from satellite data) to identify the potential risk factors of different climate regions in four Mexican states. From May 2017 to April 2018, a total of 560 farm owners or managers answered the questionnaire, and the data were used to establish three Köppen climate classes (tropical, dry, temperate). The overall prevalence of GIN parasites in equines was 77.9% (436 out of 560). The highest percentage of GIN was detected in mules (87.5%). In addition, the highest prevalence among the climate regions was found in the temperate climate (79.9%). The identified nematodes were strongyle type (77.9%), Parascaris equorum (5.7%), Strongyloides (0.7%) and Oxyuris equi (2.9%). The highest mean value of strongylid eggs per g faeces was found in the dry climate (632.6 ± 96.8), followed by that in the tropical climate (518.3 ± 49.7) and temperate climate (383.8 ± 30.2); however, a similar prevalence was observed between different climate regions. Age and sex were identified as risk factors for high shedding of strongyle eggs: the odds ratios for higher shedding intensities were 3.858 for geldings compared to mares, 2.602 for 6-10-year-old equines and 3.597 for ≤16-year-olds compared to young equines (≤5 years old).

Abstract
Theileriosis is an important disease of economic significance which badly affects the equine husbandry of developing countries. The present study was planned to investigate the molecular prevalence of theileriosis, associated risk factors, and alterations in hematological parameters of donkeys and mules from district Mianwali, Punjab, Pakistan. Blood samples from 150 equids (n = 75 donkeys; n = 75 mules) were examined microscopically, and the genomic DNA from each sample was processed for the amplification of the 18S rRNA gene of Theileria. The polymerase chain reaction confirmed isolates were purified followed by sequencing. The data regarding the analysis of risk factors were collected in a predesigned questionnaire and statistically analyzed by logistic regression analysis. An overall prevalence of 17.33% was noted in this study. Donkeys showed more prevalence followed by mules being 20.0% and 14.7%, respectively. The study isolates showed high resemblance (99%) with isolates from the United States of America, Spain, Brazil, Israel, Cuba, France, South Africa, Korea, Turkey, Tunisia, India, E. Caribbean, and Nigeria. The potential risk factors found to be significantly associated (P < .05) with disease dynamics were tick infestation on study animals, previous tick history, and house hygiene. A significant (P < .05) decrease in the number of platelets, erythrocytes, hemoglobin level, and packed cell volume was observed in donkeys and mules suffering from theileriosis compared with the healthy ones. The study is the first report regarding the molecular characterization of theileriosis in donkeys and mules in Pakistan. The findings will be effectual in designing effective control strategies for this disease in Punjab, Pakistan.

Abstract
Aim: This study aimed to investigate the prevalence and intensity of nematode infection among slaughtered donkeys in Kaltungo, Nigeria. Materials and Methods: A total of 72 fecal samples were examined by salt flotation and the modified McMaster fecal egg count technique to morphologically identify nematodes eggs and determine their egg per gram (EPG) outputs. Results: Out of a total of 72 (100%) donkeys sampled, 36 (50%) tested positive, but the prevalence of nematodes was independent of the age, sex, and breed of donkeys (p>0.05). Among the four species of nematodes identified in single and mixed infections, Strongylus spp. (27.8%) and Dictyocaulus arnfieldi (13.9%) were the most prevalent followed by Strongyloides westeri (5.6%) and Trichonema spp. (5.6%). Infected donkeys had moderate overall mean EPG (801.39±611.3) with no statistical differences between age groups and sexes (p>0.05), but means of EPG were significantly higher (p<0.05) in Duni (1026.92±719.55) than Idabari (673.91±514.75). Light EPG count was recorded among 63.9% of infected donkeys, while 16.7% and 19.4% had moderate and severe infections, respectively. Conclusion: The prevalence and importance of equine nematodes were discussed in connection to their epidemiology and control. Furthermore, the preponderance of light infection may suggest that donkeys in this environment developed resistance to nematode infection and are potential reservoirs for other equines.
