The objective of this study was to experimentally evaluate the pathogenicity of an Actinobacillus seminis isolate named SAAS01 in goats. Animals were challenged with 2 mL of a suspension containing 1,5 × 108 CFU/mL of A. seminis (SAAS01 isolate) through the intrapreputial, epididymis tail, and conjunctival routes.

To investigate and assess the sequential pathological changes in the epididymis and testis of young rams injected intra-epididymally with Actinobacillus seminis.Twenty yearling Suffolk and Suffolk-cross rams were randomly divided into two groups comprising 16 test and four control animals. Each test ram received 2.3 x 109 cfu/ml of A.

To investigate and assess the epididymal and testicular lesions in rams up to 44 days after inoculation with Actinobacillus seminis via various routes.Forty-four young (18-24 months old) rams were randomly divided into nine test and two control groups (n=4 per group). The test rams were infected by installation, drenching or injection of A.

SummaryEighteen strains ofActinobacillus seminisisolated from ovine semen samples and epididymitis were characterized according to their cultural and biochemical behaviour. The semen samples were collected from young, unmated and mature breeding rams suffering from epididymitis or subclinical genital infection.AllA.

The API ZYM system, a commercially-available technique that measures bacterial enzyme activity was used to test 43 isolates identified as H. somnus, H. ovis or A. seminis and 19 from related genera. The enzyme patterns resulting from the API ZYM differentiated H. somnus and H. ovis from A. seminis and related genera but not from each other.

To investigate and assess the susceptibility, lesions and route of dissemination in the accessory sex organs of young rams experimentally infected with Actinobacillus seminis.The accessory sex organs were obtained from 64 young rams. The test rams (n=52) were infected by instillation, drenching or injection of 2.3 x 10(9) cells/ml A.

Three Australian isolates of “Histophilus ovis,” ten strains of “Haemophilus somnus” from North America, Australia, and Europe, and two American strains of “Haemophilus agni” were investigated by the deoxyribonucleic acid (DNA)-DNA hybridization (renaturation) method to determine their genetic interrelationships and their levels of relatedness to ...

SEROLOGICAL COMPARISON BETWEEN HISTOPHILUS OVIS, ACTINOBACILLUS SEMINIS AND BRUCELLA OVIS
Australian Veterinary Journal, 1978SUMMARY: The serological relationships between 4 strains of Histophilus ovis, the neotype strain of Actinobacillus seminis and Brucella ovis were examined using a cross‐absorption complement‐fixation technique.It was found that the 4 strains of H. ovis were serologically homologous and that an incomplete relationship existed between these organisms and

DNA fingerprinting of Haemophilus somnus, Histophilus ovis and Actinobacillus seminis
1997H. somnus, H. ovis and A. seminis are closely-related Gram-negative pleomorphic bacteria. They are very similar in cultural and biochemical characteristics and these phenotypic characteristics are highly variable between strains of each species. Thus their identification is often uncertain. H. somnus causes thromboembolic meningoencephalitis, pneumonia
