Two cases of orchitis and epididymo-orchitis in broiler breeders are described. The first case occurred in a 62-week-old rooster showing signs of breeding inactivity. Grossly, the left testis was abnormally shaped and had multiple yellow foci, prominent blood vessels, and a gelatinous mass on the surface. The right testis and other tissues appeared normal. A pure, heavy growth of Staphylococcus aureus was obtained on bacterial culture, and intralesional Gram-positive cocci were numerous on… 
Pathogenesis of Gallibacterium anatis in a natural infection model fulfils Koch’s postulates: 2. Epididymitis and decreased semen quality are the predominant effects in specific pathogen free cockerels
The present study provides novel data on the impact of a G. anatis infection in cockerels in a natural infection model, thus helping to elucidate bacterial distribution, pathological lesions as well as influences on semen quality.
Decrease of Fertility in a Broiler Breeder Flock due to Testicular Atrophy
A combination of a recent introduction of replacement (spiking) males, poor environmental conditions, and decreased feed consumption led to the loss of weight, testicular atrophy, and decreases or no spermatogenesis in individual birds, collectively resulting in decreased flock fertility.
Newcastle disease virus induces testicular damage and disrupts steroidogenesis in specific pathogen free roosters
Results indicate that NDV infection induces a severe inflammatory response and histological changes, which decrease the steroidogenesis.
Ulcerative Dermatitis and Valvular Endocarditis Associated with Staphylococcus aureus in a Hyacinth Macaw (Anadorhynchus hyacinthinus)
This case suggests that endocarditis associated with S. aureus septicemia is a potential complication of feather damaging behavior and should be integrated into the differential when pet parrots with dermatitis are in proximity to owners.
Effects of Lipopolysaccharide on the Recruitment of T Cells in the Seminal Tract of Roosters
Results suggest that both CD4 + and CD8 + T cells are recruited in response to LPS stimulation in the rooster seminal tract, and the T cell-mediated local immune system is active in that organ.
Escherichia fergusonii identified in preputial swabs from healthy Aceh cattle by phylogenetic 16S rRNA analysis
It is concluded that the E. fergusonii bacterium positively presence in preputial swab samples of clinically healthy Aceh cattle population is potentially allowing the bacterium to be spread during natural mating or semen collection processing for artificial insemination in cattle breeding farm.
The Good, the Bad and the Ugly of Testicular Immune Regulation: A Delicate Balance Between Immune Function and Immune Privilege.
The delicate balance within the testis that provides immune privilege to protect the germ cells while still allowing for immune function to fight off pathogens and tumors is discussed.


Epididymal lithiasis in roosters and efferent ductule and testicular damage.
Information is confirmed about the epididymal lithiasis, which appears to be unique for roosters but to occur around the world, and the severity of the lesion points to potentially severe economical impact in the poultry industry.
Prepubertal Exposure to the Live Attenuated Avian Infectious Bronchitis Virus Induces Epididymal Stones in the Rooster after Puberty
The results indicate that epididymal stone formation begins with aggregations of sperm, cell debris and macrophages immediately after puberty, which is followed by calcium deposition.
Avian Infectious Bronchitis Virus: A Possible Cause of Reduced Fertility in the Rooster
It is concluded that the use of a live attenuated AIBV vaccine increases the incidence of epididymal stones in roosters, resulting in decreased sperm production and decreased serum testosterone concentrations.
[Cocks with experimentally induced acute typhoid].
Acute typhoid infection was induced in cocks of the New Hampshire breed at the age of 14 months within the period of intense productivity, and the morphologic changes seen in the parenchymal organs were analogous with those that have been demonstrated so far.
Epididymal Stone Formation and Decreased Sperm Production in Roosters Vaccinated with a Killed Strain of Avian Infectious Bronchitis Virus
It is concluded that use of a killed vaccine does not reduce the incidence of epididymal stones.
Poultry Diseases and Meat Hygiene: A Color Atlas
"Poultry Diseases and Meat Hygiene" has practical application due to the inclusion of chapters on exotic diseases, residues, food safety, HACCP and ratites.
Diseases of Poultry
VERY few veterinary surgeons have thought fit to write a book on diseases of poultry. Mr. Ernest Gray has done justice to the subject and is to be congratulated on his effort. A book of this size,
