Human spermatids from ejaculate and testicular tissue have been utilized for evaluating human fertilization by intracytoplasmic sperm injection (ICSI) and, where possible, compared with spermatozoa utilizing sibling oocytes. Round and elongated spermatids obtained from ejaculates were either prepared through Percoll gradients or isolated and washed individually using subzonal insemination needl...

Equine influenza, caused by the H3N8 subtype, is a highly contagious respiratory disease affecting equid populations worldwide and has led to serious epidemics and transboundary pandemics. This study describes the phylogenetic characterization and replication kinetics of recently-isolated H3N8 virus from a nasal swab obtained from a sporadic case of natural infection in an unvaccinated horse fr...

It has been demonstrated that equine neutrophils, but not eosinophils, require exogenous arachidonic acid for calcium ionophore A23187-induced leukotriene synthesis. Because cytosolic phospholipase A(2) (cPLA(2)) plays an essential role in leukotriene formation in leukocytes, we investigated the presence of a functional cPLA(2) in equine neutrophils. To determine whether cPLA(2) from neutrophil...

A total of 272 methicillin-resistant Staphylococcus aureus (MRSA) from equine infections originating from 17 equine hospitals and 39 veterinary practices in Germany as well as 67 isolates from personnel working at equine clinics were subjected to molecular typing. The majority of isolates from horses was attributed to clonal complex (CC) 398 (82.7%). Within CC398, 66% of isolates belonged to a ...

This report discusses the current research findings regarding veterinarian-client interactions and relationships and how they relate to equine veterinary practice. The application of the relationship-centered care model in equine medicine is described, and proven clinical communication skills that illustrate how to incorporate this model into equine veterinarian-client interactions are provided.

KONDRACKI, S., M. IWANINA and A. WYSOKINSKA, 2015. Assessment of the relationship between physical ejaculate parameters and the sexual activity of Landrace boars. Bulg. J. Agric. Sci., 21: 882–888 The study involved 11 Landrace boars, aged 8-9 months and used for insemination purposes. Each boar was assessed four times for its sexual activity: at the beginning of breeding service and after 3, 6...

Abstracts of the 11th International Conference on Equine Exercise Physiology, Uppsala, Sweden, Sunday June 26 to Friday July 1, 2022. A total 192 abstracts cover a wide range topics relevant athletic horses, including biomechanics, cardiorespiratory and musculoskeletal responses exercise, genetics, training nutrition, as well emerging technologies, physiotherapy, rehabilitation equitation scien...

Several reports demonstrating the presence of messenger RNAs for sperm-specific nucleoproteins, the protamines PRM-1, PRM-2, and the transition protein TP-1 as well as beta-actin, c-MYC, HLA1, and beta 1 integrin have challenged the accepted view of the transcriptional dormance of terminally differentiated spermatozoa. Whatever nuclear activity the ejaculate spermatozoon may possess, these data...

Aim: Present investigation was carried out to study the physical characteristics of Kankrej bulls semen by evaluation of various semen parameters from neat semen and at various stages of semen preservation. Materials and Methods: A total of 60 ejaculates, 10 each from 6 mature Kankrej bulls, once in a week for 10 weeks, were collected and analyzed for various semen attributes. Result: The mean ...

The coyote is a seasonally breeding mammal, with most copulations occurring between December and April (depending on location). The objective of this study was to characterize seasonal changes in serum testosterone concentrations, testicular volume, and ejaculate quantity and quality in captive male coyotes. There were seasonal differences in testicular volume, with the greatest volume (20.2+/-...
