Assessment of listing and categorisation of animal diseases within the framework of the Animal Health Law (Regulation (EU) No 2016/429): ovine epididymitis (Brucella ovis)

EFSA Journal, Volume 15, Issue 10, October 2017., 2017
Abstract Ovine epididymitis (Brucella ovis) has been assessed according to the criteria of the Animal Health Law (AHL), in particular criteria of Article 7 on disease profile and impacts, Article 5 on the eligibility of ovine epididymitis to be listed, Article 9 for the categorisation of ovine epididymitis according to disease prevention and control ...

Testosterone and estradiol modify the expression of adhesins and biofilm formation in Actinobacillus seminis

FEMS Microbiology Letters, 2023
Abstract Actinobacillus seminis is the causal agent of epididymitis and has other effects on the reproductive tracts of small ruminants and bovines. This bacterium causes infection when luteinizing (LH) or follicle-stimulating hormones increase, and hosts reach sexual maturity. LH induces female ovulation and male testosterone production,

Actinobacillus seminis Secretes a Metalloprotease That Degrades Bovine Fibrinogen and IgG

The Pakistan Veterinary Journal, 2023
Actinobacillus seminis is a Gram-negative bacterium member of the Pasteurellaceae family. Even though it is part of the ovine microbiota it is also the causal agent of genital organs affections, particularly epididymitis and orchitis. Infections caused by this microorganism generate economic losses to the ovine industry due to impaired fertility and ...

Inducción experimental de epididimitis en ovinos por inoculación intrauretral con Actinobacillus seminis: estudio bacteriológico, serológico e histopatológico

Revista Mexicana de Ciencias Pecuarias, 2012
Con el objetivo de inducir la infección experimental de A. seminis, se utilizaron 18 corderos de seis meses de edad: 4 testigos negativos, otros 3 se inocularon con A. seminis vía intraepididimal (IE) y 11 fueron inoculados por vía intrauretral (IU) como

Testosterone and estradiol regulate the expression of proteases and a hemoglobinase in Actinobacillus seminis

FEMS Microbiology Letters
Abstract Actinobacillus seminis is a causative agent of epididymitis, infertility, and sterility in sexually mature ruminants. Previous studies suggest that sex hormones regulate the expression of A. seminis virulence factors, promote its growth, and support adhesin expression and biofilm formation; however, the effects of these hormones
