The type-2 M protein SCM-2 binds fibrinogen and facilitates antiphagocytic properties.

is a zoonotic agent that causes severe invasive diseases in domestic animals and humans, but little is known about its pathogenesis and virulence mechanisms so far. SCM, the M-like protein expressed by , is considered one of the major virulence determinants. Here, we report on the two distinct groups of SCM.

New variant strain of Streptococcus canis with Lancefield group C isolated from canine otitis externa.

Every basic course in microbiology teaches us, Streptococcus canis always tests positive for Lancefield group G. Surprisingly, we identified a strain of S. canis with Lancefield group C, cultured from a dog with otitis externa after lateral ear canal resection.

Limiting Factors in Treatment Success of Biofilm-Forming Streptococci in the Case of Canine Infective Endocarditis Caused by .

An 8-year-old male Rhodesian Ridgeback was presented with fever and severe thrombocytopenia. Clinical and laboratory examination, echocardiography, blood culture, and pathohistology revealed evidence of infective endocarditis, ischemic renal infarcts, and septic encephalitis. Treatment was started immediately but the dog's condition worsened, and the dog had to be euthanized.

Progressive Lameness of a Greater One-Horned Rhinoceros () Associated with a Retroperitoneal Abscess and Thrombus Caused by Subspecies .

In rhinoceroses, lameness is an occasionally seen symptom primarily caused by lesions affecting the feet and interdigital space. A 3-year-old male Greater one-horned rhinoceros developed a progressive, severe movement disorder of the right hind limb with subsequent death.

The Role of spp. in Bovine Mastitis.

The genus belongs to one of the major pathogen groups inducing bovine mastitis. In the dairy industry, mastitis is the most common and costly disease. It not only negatively impacts economic profit due to milk losses and therapy costs, but it is an important animal health and welfare issue as well.
