Neuraminidase Activity of Pasteurella haemolytica Isolates

Serological groups among untypable bovine isolates of Pasteurella haemolytica.

Ten Pasteurella haemolytica isolates from the nasal passages of cattle, untypable by the indirect hemagglutination procedure, were grouped into three serotypes by the rapid plate agglutination procedure. Serological specificity and serum absorption results showed that the 10 indirect hemagglutination-negative isolates belonged to three distinct serotypes and were not members of established sero...

Pasteurella haemolytica A2

Twenty-one healthy local goats of about eight months old were divided into four groups consisting of six animals in groups 1, 2 and 3 and three animals in group 4. Goats in groups 1 and 2 were inoculated intratracheally with Mycoplasma arginini. Goats in group 2 were inoculated again with Pasteurella haemolytica A2 six days later. Goats in group 3 were inoculated intratracheally with P. haemoly...

Combinations of macrolide resistance determinants in field isolates of Mannheimia haemolytica and Pasteurella multocida.

Respiratory tract infections in cattle are commonly associated with the bacterial pathogens Mannheimia haemolytica and Pasteurella multocida. These infections can generally be successfully treated in the field with one of several groups of antibiotics, including macrolides. A few recent isolates of these species exhibit resistance to veterinary macrolides with phenotypes that fall into three di...
