I have been reading in the Merck Manual about pasteurella. This line worries me the most, I think:
"Rabbits may develop Pasteurella septicemia and die acutely without any clinical signs. Septicemia necropsy findings may reveal only congestion and petechial hemorrhages in multiple organs."
Also:
"Treatment is difficult and may not eradicate the organism. Antibiotics seem to provide only temporary remission, and the next stress (eg, kindling) may cause relapse. Enrofloxacin (200 mg/L of drinking water for 14 days or 5-10 mg/kg parenteral, bid for 14 days) is effective for upper respiratory P multocida infections. Tilmicosin (25 mg/kg, SC) has been reported as an effective treatment for pasteurellosis. Procaine penicillin (60,000 IU/kg for 10 days) was recommended for indiviual rabbits, but its use should be cautioned as deaths from enterotoxemia often follow penicillin administration.
An effective vaccine has not been developed; therefore, the best method of control in large rabbitries is strict culling. Two methods to free a production colony of Pasteurella have been reported. The first involves culture and culling of positive animals; once the colony is Pasteurella -free, it must be maintained in isolation. In the second method, pregnant does past kindling are treated with enrofloxacin. While does remain Pasteurella -culture positive the kits remain Pasteurella -culture negative. Carriers can be identified by an indirect fluorescent antibody test on nasal swabs."
So I am guessing this means the end of me doing any rescuing. I couldn't take the risk of bringing in more, when this disease is so contagious.
