contagious equine metritis (cem) is a venereal transmissible and non-systemic disease of horses caused by a gram negative, bacillus or cocco-bacillus and non-motile bacterium, taylorella equigenitalis which can lead a transient infertility in mares. identification of this bacterium is based on microaerophilic culture, but weakness of this bacterium in growth compared with secondary and symbioti...

UNLABELLED The duration of electrocardiographic (ECG) parameters: PQ, QT and R-R intervals change during long-term and short-term observation as the consequence of the fluctuations in autonomic nervous system activity among others dependent on the exercise and resting. There is no data of horse breed influence on these parameters. The aim of the study was to assess the duration and the variabil...

Equine protozoal myeloencephalitis is a progressive neurologic disease of horses most commonly caused by infection with the apicomplexan parasite Sarcocystis neurona. Factors affecting neuroinvasion and neurovirulence have not been determined. We investigated the pathogenesis of infection with S. neurona in horses with severe combined immune deficiency (SCID). Two immunocompetent (IC) Arabian h...

BACKGROUND Egyptian Arabian horses have been maintained in a state of genetic isolation for over a hundred years. There is only limited genetic proof that the studbook records of female lines of Egyptian Arabian pedigrees are reliable. This study characterized the mitochondrial DNA (mtDNA) signatures of 126 horses representing 14 matrilines in the Egyptian Agricultural Organization (EAO) horse-...

mutannabi the well-known arab poet has dedicated many lines of his poetry to describing animals directly or indirectly. among the animals to whichmutanabbi has paid attention the horse has a very special status. most of the lines in which he has in some way described horses or horse riders are the lines about fights and battles in which the poet depicts the victories and bravery of the courageo...

This case report describes the use of a subcutaneously applied 4.7-mg deslorelin acetate implant in a three-year-old Arabian crossbred stallion showing unwanted strong male behaviour. Following deslorelin acetate implantation the stallion showed a short transitional increase in male behaviour. A 'gelding-like' behaviour was noted 15 days (D15) after treatment. The horse was surgically castrated...

Background: Artificial insemination with chilled sperm is a reproductive biotechnology often used in horse breeding. However, maintaining the acceptable quality after cooling, which affects frequency of pregnancy, remains an urgent problem at present time. Therefore, clarifying role important physiological metabolites, such as L-carnitine and nitric oxide, significant aspect terms possible impr...

background: minerals are essential materials in animal reproduction. the determination of these elements is valuable in relation to different conditions in arabian horses. objectives: the purpose of this study was to evaluate the effects of pregnancy on certain macro and micro minerals in arabian horses. methods: blood samples were collected from one hundred apparently healthy mares from differ...
