Salmonella in Cattle

Hello I am from Belarus. Vaccines used to control Salmonella in our country. Vaccines are live (for pigs) and inactivated (for cattle). I am very interested the vaccination of animals done in your country, what vaccines You use. Thank You

Within the last six months, salmonella scenarios have shown up in 26 states. The diseases have made seventy seven people sick. The strain of salmonella, called Salmonella Heidelberg, can be hard to handle. The bacteria are resistant to several medications. The authorities have yet to pin down a reason for this outbreak, though ground turkey is possibly the offender. Resource for this article: 6 month salmonella outbreak still leaving FDA mystified

I would be hesistant to associate all S. Heidelberg outbreaks to turkey in all 26 states. I think it is important to keep an open mind, and recognize that s. Heidelberg is commonly found in cattle as well. The multi-resistance is a common feature of S. Heidelberg isolates. I tried to check out the CDC report, and I do not see information about PFGE typing or other genotypic method confirming that this outbreak is due to a single strain. This is needed since multi-resistance in Heidelberg is common. If anyone has any information regarding PFGE typing then this may indicate a single source of the outbreak.

This is a very important topic which we discussed already in our class lecture, where we got a lot of knowledge from our respected teacher Prof. Dr . M. S . Qureshi. If there is availability of vaccines, then what is the protocal for the vaccination against Salmonella?

The author of the article has explained about salmonella and its serotye which causes health hazards both to human and animals. As we know that the infection of salmonella occurs in clinical as well as in sub clinical .The sub clinical type is more serious because the shedding of organism occurs constanty without any sign and symptoms showing in the host animals, so the risk of the infection is high because no treatment and diagnosis in case of subclinical infection both to humans and animals. So for control of the infection the complete diagnosis and treatment should be done in both clinical and subclinical cases of salmonellosis.The author of the article has explained very serious and common hazards facing both by humans and animals. So thanks to the author for such an important information.

Dear Hafiz, There is currently no general good vaccination against Salmonellosis in ruminants. Vaccines have been developed for poultry and pigs, where the hazards to humans are greater. In poultry there are a few serotypes, Gallinarium and Pullorum, that are poultry adapted, and causes disease in poultry, and for these there are world-wide vaccinations. There have been attempts made to make autogenous vaccines against S. Dublin, which is a cattle-adapted serotype causing severe disease in calves. There are no world wide registered vaccines. As Dr Muambar Shah, so rightly pointed out, the fact that most dairies do not even know that they have Salmonella in their dairy herd, because there are no clinical symptoms.. makes Salmonella control hard. There are currently only a few countries that have Salmonella control in ruminants, and these are the Scandinavian countries and Finland.
