[Pasteurella multocida as the cause of disease outbreaks in commercial poultry flocks].
Six cases of fowl cholera in growing turkeys and 3 in adult breeder chickens of the broiler type as well as one case each of a Pasteurella (P.) multocida-associated disease in ducklings and goslings were described in consideration of own laboratory findings and available informations of the case history. Furthermore a report is given on a treatment strategy successfully used in turkeys with highly acute fowl cholera. All the P. multocida strains isolated culturally could be assigned to the subspecies multocida. In one case Bordetella avium, Salmonella (S.) arizonae and S. hadar were additionally cultured form part of turkeys submitted. P. multocida and Moraxella (Pasteurella) anatipestifer could be determined as the causative agents of the disease of ducklings and goslings. P. multocida strains from turkeys were identified serologically as serovars A:3.4 (3x), F:3.4 (2x) and A:3 (1x); those from the breeder chickens as A:3 (3x); and one each from ducklings and goslings as F:3.4 and -:3. (uncapsulated). No death occurred in turkeys with clinical signs of a highly acute fowl cholera if the treatment of the affected birds was started with an intravenous injection of sulfadimethoxine and continued with a combination of sulfachlorpyridazine (SCP) and trimethoprim (TMP) given in the drinking water for 5 days. However relapse occurred 2-3 days after withdrawal of the drug, although the therapy was clinically highly effective. The recurrence of the disease could be prevented reliably if the turkeys were vaccinated with an effective oil-based bacterin and subsequently treated with the SCP-TMP combination given in drinking water over a 12 day period.
