As bacterias sao os principais agentes etiologicos da mastite infecciosa ovina, com destaque para Staphylococcus aureus, Mannheimia haemolytica, Streptococcus spp., Escherichia coli, Pseudomonas spp., Arcanobacterium
pyogenes, estafilococos coagulase negativa, Corynebacterium spp.
Other potentially pathogenic bacteria isolated occasionally included Arcanobacterium
progenes, [alpha]-hemolytic streptococci, and several Enterobacteriaceae, but they could not be correlated with either the clinical signs or the presence of P.
pyogenes, Escherichia coli, Fusobacterium spp.
O genero Corynebacterium pertence aos actinomicetos aerobicos, que tambem contempla outros microrganismos patogenicos para animais incluindo: Nocardia sp, Rhodococcus equi, Mycobacterium sp e Arcanobacterium
pyogenes (12), visto que compartilham certas caracteristicas da parede celular, incluindo espessura, presenca de acidos micolicos, acidos graxos saturados e insaturados (4, 11).
The vanA gene cluster is located on transposons or related elements (6) and has also been found in nonenterococcal species such as Arcanobacterium
(Corynebacterium) haemolyticum, Oerskovia turbata, Bacillus circulans, and Streptococcus gallolyticus (13-16).
The main endometritis causing bacterial pathogens are mixed cultures that include Arcanobacterium
, Staphylococcus, Streptococcus, Escherichia, Klebsiella and anaerobic bacteria such as Fusobacterium necrophorum and Bacteroides species.
The species was originally known as Corynebacterium pyogenes and Actinomyces pyogenes and then as Arcanobacterium
After reclassification to the genus Arcanobacterium
, this organism is now recognized as a member of the recently designated genus Trueperella .
La bacteria mas frecuentemente aislada fue Arcanobacterium
haemolyticum con un 20,14% de manera individual y un 0,7% en coinfecciones.

For example, pharyngitis caused by Arcanobacterium
haemolyticum can have a similar clinical syndrome as group A strep, including fever, exudative pharyngitis, and accompanying rash.
The gene Arch_1773 in the Bacterial pathogen Arcanobacterium
haemolyticum was analyzed using standard bioinformatics tools during a gene annotation project.
