Mules arena distinct equine species with unique physiological and behavioral characteristics. Horses, belonging to the species Equus ferus caballus, are domesticated animals known for their speed, strength, and versatility in various roles, including riding, racing, and work. Mules, on the other hand, are hybrid animals resulting from the crossbreeding of a male donkey (jack) and a female horse (mare). They inherit traits from both parents, often exhibiting the endurance and hardiness of donkeys combined with the size and strength of horses. Mules are typically sterile due to their hybrid nature, possessing 63 chromosomes, an intermediate number between horses and donkeys. This page compiles peer-reviewed research studies and scholarly articles that explore the genetic, anatomical, and behavioral differences between mules and horses, as well as the mule's role in agriculture, transportation, and recreation.
A Retrospective Study of Pythiosis in Domestic Animals in Northeastern Brazil. Pythiosis is an endemic disease in northeastern Brazil and we now report the epidemiological, clinical and pathological findings in a retrospective study of naturally occurring cases in domestic animals. From January 1985 to December 2020, the Laboratory of Animal Pathology of the Federal University of Campina Grande examined 13,542 tissue samples from necropsies and biopsies. Among these samples, 306 were diagnosed as pythiosis: 195 cases in horses, 75 in sheep, 19 in dogs, six in mules, four in cattle, three in cats, two in goats, one in a donkey and one in an ostrich. Affected equids had le...
Assessing the impact of USER-treatment on hyRAD capture applied to ancient DNA. Ancient DNA preservation in subfossil specimens provides a unique opportunity to retrieve genetic information from the past. As ancient DNA extracts are generally dominated by molecules originating from environmental microbes, capture techniques are often used to economically retrieve orthologous sequence data at the population scale. Post-mortem DNA damage, especially the deamination of cytosine residues into uracils, also considerably inflates sequence error rates unless ancient DNA extracts are treated with the USER enzymatic mix prior to library construction. While both approaches have rec...

Serum cortisol in mules intended for agricultural work. Cortisol is a hormone secreted by the adrenal glands that is stimulated by physiological and pathological factors and has been studied widely in equids, but not in mules. The objectives of this study were to obtain a reference value for serum cortisol in mules destined for agricultural activities and to identify age- and gender-related differences in the value. The concentration was obtained in blood samples using a commercial sandwich ELISA specific for cortisol. The concentration was 96.3 ± 40.6 ng/ml and similar between age groups and genders.
16S rDNA and ITS Sequence Diversity of Burkholderia mallei Isolated from Glanders-Affected Horses and Mules in India (2013-2019). Glanders is a highly contagious and fatal infection of equids caused by the bacteria known as Burkholderia mallei. It is one of the notifiable equine diseases and is still present in Asia, South America and Africa. In India, glanders re-emerged in 2006, and thereafter, increasing numbers of cases were reported in different regions of the country. Between 2013 and 2019, 39 B. mallei were isolated from glanders-affected horses (n = 30) and mules (n = 9) from seven states of India such as Uttar Pradesh, Haryana, Delhi, Himachal Pradesh, Gujarat, Maharashtra and Tamil Nadu.

The Use of Draught Animals in Rural Labour. This study discusses scientific findings on the use of draught animals such as equids (i.e., horses, mules, and donkeys) and bovids (i.e., cattle and water buffaloes) in rural labours. Relevant peer-reviewed literature published between 1980 and 2021 was retrieved from CAB Abstracts, PubMed, ISI Web of Knowledge, and Scopus databases. Although animals were used to produce draught power since their domestication and are still being used for this purpose, mechanisation has markedly reduced animal labour demand in agriculture. However, the process was uneven across continents according to economi...
Analysis of Virulence and Antimicrobial Resistance Gene Carriage in Staphylococcus aureus Infections in Equids Using Whole-Genome Sequencing. While Staphylococcus aureus is associated with significant morbidity and mortality in equids (horses, donkeys, and mules), few studies have performed whole-genome sequencing to fully categorize large collections of equine isolates. Such sequencing allows for a comprehensive analysis of the genetic lineage and relationships of isolates, as well as the virulence genes present in each, which can be important for understanding the epidemiology of strains and their range of infections. Seventy-two clinical Staphylococcus aureus isolates from equids were collected at the Texas A&M University Vet...
Influence of workload and weather conditions on rolling behaviour of horses and mules. We evaluated the influences of workload intensity, bath handling and environmental conditions in the rolling behaviour of horses and mules. For this purpose, animals were observed after being exposed to different levels of workload and the rolling behaviour was recorded and described. During all testing procedures, the weather condition (temperature and humidity) was registered by a Black globe and Wet Bulb apparatus. Horses frequently rolled after intense exercise and after bath handling, independently of the weather condition. Mules frequently rolled after control (no exercise) and intense e...
Seroepidemiology of Sarcocystis neurona and Neospora spp. in horses, donkeys, and mules from Colombia. Sarcocystis neurona and Neospora spp. are related protozoa that can cause equine protozoal myeloencephalitis (EPM). The present study aimed to determine the frequency of antibodies to these parasites in 649 equids (351 horses, 267 donkeys, and 31 mules) from six departments in the North and Northwest of Colombia. For this purpose, the indirect fluorescent antibody test (IFAT) was used for detecting antibodies against S. neurona and Neospora spp. with a cut-off point of 1:20 and 1:50, respectively. A binomial logistic regression model was selected to predict variables associated with exposure. ...
Frequency and factors associated of potential zoonotic pathogens (Borrelia spp., Rickettsia spp., Leishmania spp., and Anaplasma phagocytophilum) in equids in the state of Bahia, Brazil. Currently, various zoonotic diseases are classified as emerging or reemerging. Because equids have a direct relationship with various vectors, they are possibly more frequently exposed to zoonotic agents than are humans. The undeniable importance of diseases such as human granulocytic anaplasmosis, spotted fever, and leishmaniasis for both public and animal health, as well as the possibility of equids acting as sources, reservoirs, or even sentinels for these pathogens, justifies the detection of their frequency and factors associated with infection in equids from northeastern Brazil. Methods:...
A Fast PCR Test for the Simultaneous Identification of Species and Gender in Horses, Donkeys, Mules and Hinnies. Having considered that the current methods are costly and time-consuming, we designed an only 3 pairs primer-based PCR test to accurately identify the species and gender in horses, donkeys, mules and hinnies. Through a thorough sequence comparison between horse and donkey's highly similar genomes, and a vast amount of preliminary confirmation, we found that three fragments, CNGB3 gene on an autosome, displacement loop region on mitochondrial DNA and SRY genes on chromosome Y, within these equine DNA, are enough to enable us achieving our goal. The PCR test described here would be an economical...
