Introduction Fowl cholera is an infectious disease caused by the bacterium Pasteurella multocida. This species is named “multocida”, which may be interpreted as a bacterium that "kills" (cida) "many" (multo). In 1879, Pasteur was able to cultivate this bacterium; this was the first time that disease-causing bacteria were grown in culture media, outside the animal host. Pasteur inadver...

FOWL cholera is acute and fast spreading. slow growing probiotics are not enough to exclude this bacteria by compitition

FOWL cholera is an acute disease and spreads fast especially in deep litter flocks. probiotics cannot overwhelm once the disease sets in. As a preventive, it has been guess work using probiotics.
whether probiotics is working or the flock is not exposed.
my guess is the flock is not exposed.

I am interested to know the vaccination schedule for the control of FC .we are using killed bacterin at age of 12wks followed by boosted after 12 wks. no satisfactory results.

we decide on the age of vaccination basing on the age at which we get the out break. If we are seeing outbreaks in growing, we can vaccinate at 6th to 8th week. Repeat after 3 weeks. If we have a seperate brooding/Growing farm where there is no problem but the birds will be going to a layer unit endemic for FC, then it is better to vaccinate at 12/13 weeks and repeat after 3 weeks.
2. There are multi strain vaccines. Please go through the profile of the vaccine and choose one with multi strains. If you go for a local manufacturer, it is likely they incorporated the local strains responsible for the out break.
3. Keep Sulpha Methoxol+Trimethoprim powder handy and use it when there is doubt. It does not interfere with killed vaccine.
Hope this helps.
Thank you

Probiotics are beneficial bacteria or yeast that are healthy to the intestine of the animal
Probiotics mimic gram negative flagellated bacteria such as E Coli pasteurekka and other harmful bacteria by competing to attach to their receptive sites
So when probiotics are fed to monogastrics, for example, they get attached to the lumen epithelium receptive sites, that are attachments sites for gram negative bacteria as mentioned above
When these predilection sites for pathogenic bacteria are occupied by these probiotics, they make these flagellated bacteria unable to get themselves attached to where their sites, where they cause erosion of the intestinal lining leading to hemorrhages
The result if this process is that these pathogenic bacteria are found floating in the gut lumen until they are pushed out with the fasces thus preventing the animal from been susceptible to this infection
From the above mechanism, it is obvious that the use if probiotics will enhance the proliferation of gram positive bacteria that is beneficial to the animal immune system
Since probiotics and neutraceuticals are natural products they act as non-antibiotic growth promoters because they improved the villi morphology and improve gut health and absorption efficiency.

Although farmers are using probiotics both in feed as well in water but results are up to the desirables levels.

Probiotics are beneficial bacteria or yeasts that improve gut health, digestibility and immune system, especially in monogastrics. Probiotics are very competitive to the survival of the gram negative bacteria in the gut ,because they compete with these harmful bacteria receptive sites
You should take note that the pathogenic gram negative bacteria are mostly flagellated like the and they are all harmful to the host
In the pathogenesis of gram negative flagellated bacteria, they start their damage in the lumen of the host gut by getting attached to specific receptive sites on the epithelium of the gut, and proceed in their pathology by eroding the surfaces of the sites, thus causing inflammation and poor digestibility and absorption. When Probiotics are fed to animals, they compete to attach to these sites.

Does it mean that FC vaccination is not recommended for broilers that are kept for 7-10 weeks?

Uwalaka Chinomso it is not advisable because of short production life span

In layers vaccination is important. Use of Acidifiers have better results to control FC.

The antigenic local strain of the FC Organisms should be typed before applying the matching serovar or zero variant. So type the prevalent P. multocida in the environment.

I rear layer birds and lately I observed my bird will go to the corner of the pen and fold up, wisin for breath and few hours after they will die. There is no sign of mucus on their nostril and they can hardly walk, please help what to used to help my birds

Despite all positive control mechanisms, ceftriaxone is the most crucial drug to control heavy mortality within a short period. I have been using it since 2017 in Bangladesh.
