Swine neonatal diarrhea is one of the major causes of death and economic losses in swine production. The enterotoxigenic (ETEC), verotoxigenic (VTEC) and porcine enteropathogenic (PEPEC) strains are one of the most representative pathogenic variants of E. coli (9, 11, 12). There are a number of virulence factors associated with ETEC strains, such as the production of heat-labile (LT) and heat-stab ...

Dear Danka,I also agree we need some laboratory information. Heart lesions like this may be caused by many other pathogens. Kind Regards.

Yair Saar, Yes, it could be a good choice as far as a double emulsion is used (water in oil in water), not a simple one (water in oil) because the lipopolysaccharide of Pasteurella multocida, together with the oil, could produce deleterious post-vaccinal reactions, particularly in young birds.

Fowl cholera presents in various degrees. Acute cholera causes rapid death. Chronic cholera can take weeks to cause death. Typical carriers are rodents. A good systematic rodent control program will help reduce exposure. Fowl cholera is caused by Pasteurella multocida. It is not transmitted via the eggs, so your husband can continue to consume eggs. I would not kill the flock. Transmission is usua ...

These birds that you have might be worth maintaining the flock alive. Ask for antibiotic resistance to the lab and try to vaccinate (only if healthy) the birds. New birds, if introduced to the same flock, should be vaccinated twice previously, if possible, with a vaccine prepared with the same strain that was isolated.Birds will stay carriers, so make sure biosecurity is well maintained. Rabbits, ...

Regarding fowl cholera (in chickens), the best is to use dead or inactivated vaccines elaborated with the present local strain that is actually causing the outbreak in the farm. The protection is good if the vaccine is well grown and a good adjuvant is added. I recommend aluminium type adjuvants. Treatment with antibiotics may stop the mortality but usually Pasteurella multocida remains in th ...

Dear Nguyen Ngoc Linh Nhan, I do not know of which poultry species we are talking about. In the case of fowl cholera some avian domestic poultry species are more resistant than others. In other viral diseases, such as avian influenza all type of domestic birds may die suddenly. Also other viral diseases such as Newcastle. Best regards, Dr. Horacio Raúl Terzolo

Dear Ismet Mamode, You are right, good and strict biosecurity measures are able to control the entry of the disease. In such cases the suspension of vaccination may be justified, but completely naive birds could suffer an acute outbreak of disease if P. multocida somehow manages to break the siege of control measures. Best regards, Dr. Horacio Raúl Terzolo

It is many years since I have not seen any cases of fowl cholera in the breeders and layers. In the past, we had problems of fowl cholera. We had to vaccinate the breeders and layers twice with an oil based vaccine. As we were unable to develop an autogenous bacterial vaccine, we had to rely on commercial vaccines. Fortunately, with a strict biosecurity and control measures, we succeeded in contro ...

Dear Dr. Md.abdul Karim, Thank you for your important and pertinent question! I have to say that In Argentina we have never have had any case of avian influenza in chickens. Virus infect wild birds but up to now have never infected chickens or any other poultry species. Therefore we have no practical experience on the subject. According to the descriptions of lesions, I can imagine that many of ...
