Dear Jignesh Barot, of course tarsus-metatarsus bone marrow is a sample of choice if the only available sample is a dead bird as, for instance, only could happen when an hipper-acute presentation of the disease occurs in which the only clinical sign in the appearance of sudden deaths which may take place whilst the rest of the flock show any disease signs of fowl cholerae and you only available sa ...

Dr. Stephen Adejoro, I have been working together with my colleague Yossi Huberman. I would like to add that in Columbia Blood agar without blood P. multocida but with added equine serum colonies can easily be distinguished because they grow smaller than any possible Enterobacteriaceae o usually contaminant bacteria and have a characteristic blue color, sometimes iridescent, and therefore you can ...

Bouayad I think here blood Agar culture will display pasteurella multocida as bipolar rod-like organism ,but can not be cultured with Macko key medium. I believe laboratory experts on this platform will explain furthet

Bouayad We use Columbia agar base plus 7% bovine defibrinated blood (CLBA) and we can isolate Pasteurella multocida very well. When samples might be contaminated, we also use Agar Base without blood but with 0.1% (V/V) of equine serum (previously treated 56ºC for 30 minutes). This way it is easier to identify suspected P. multocida colonies, as they grow with some blueish color when illuminated. ...

Will most likely occured on or around age 26-28weeks in.laying flocks ,however if the farm is endemic, subsequent re occurrences will take an interval of 12 weeks to re occure wether you treat or opt for vaccination In our practice we discovered that liver degeneration is pathognomonic in fowl cholera and to get a lasting treatment the liver parenchyma cells must be regenerated ,so we need to devi ...

We all know that rodents, cats and pigs are the main source of Pasteurella multocida for commercial poultry and therefore, POOR HYGIENE is the main culprit for fowl cholera. Those farms where hygiene, rodent extermination and proper Biosecurity have been ignored, are the ones that keep breaking with the disease. Hundreds of thousands of dollars are lost not just due to the economic impact of the ...

Dr Algis Martinez Thank you so much for pointing this out. Biosecurity is probably the main instrument for improving birds’ health as well as productivity. Prevention is much better than treatment. Moreover, mostly, much cheaper. This applies not only to Fowl Cholera but also to all other diseases.

Dr.Talapaneni.Kotaiah thank you for your comments. These two diseases are commonly associated, and a good bacterin, preferably with local strains, will work well.

fazal Malik Malik Pasteurella multocida strains have great variety and these differences make treatment change quite often. For antibiotics treatment, you should always try to test sensitivity before application. Inactivated vaccines will work just fine, especially if local strain is added. Furthermore, even after vaccination, you should be aware of the possibility of a subclinical infection that ...

Folarin FaleHello and thank you for your question. These two diseases, Fowl Cholera and Fowl Typhoid, are very different and are caused by Pasteurella multocida or Salmonella Gallinarum, respectively. For antibiotic treatment you should always try to, first, isolate the bacteria and ask for your lab to perform antibiotic sensitivity tests before applying any treatment. Results may change in differ ...
