Colibacilosis, a scary and economically devastating disease

Published on: 07/31/2021
Author/s : PlusVet Animal Health

With this post, a general introduction to the disease, we start a series of articles about avian colibacillosis.Colibacilosis is one of the most common infectious bacterial diseases in the poultry industry and one of the main causes of economic loses. Such losses are caused by increased mortality and morbidity, lack of uniformity, decreased production, treatment costs and increased condemnation at...

Very good information on coli bacillosis for all involved in poultry production. Please continue the good work. Look forward to more information. It is true that contamination thru water feed litter air and in contact objects and people working on the premises cause this problem. These causes need to be identified and addressed at the management level. Treatment may or may not work, is expensive and may have to be repeated several times. Surviving birds may become carrier and may become culls or have poor performance
Biosecurity at all levels remains an effective tool.

It is unthinkable that at this point in history, Escherichia coli continues to be a problem. Perhaps we have thrown antibiotics by the window prematurely, without having an effective alternative.

E.Coli bacteria is omnipresent. we have to plan to keep it under control by reducing the further contamination through human hands. feed & water should go the birds with no human touch.
general cleanliness and good ventilation keeps the bacterial level low. variations in environment temperatures make the birds vulnerable for the infection.
Most important concerns to the veterinarian are predisposing factors like viral diseases and vaccination stress and mycoplasma. when these things are present the multiplication of e.coli is so fast that the primary treatment to kill the bacteria goes very slow.
Besides antibiotics bacteriophases are having a promising edge in the direct treatment of e.coli.

E.coli is one bacteria is first to acquires resistance against antibiotics and spread to other cohabitant bacterial species. This makes treatment more difficult and expensive. I have tried using bacteriophages against E.coli and Salmonella with great success. Phages are very specific, effective, non toxic and work on resistant bacteria as well. These can also be used along with antibiotics to control E.coli. they donot harm other normal flora present unlike antibiotics which will kill healthy microflora.

Dr.m.s.swami I am curious to know if phages are allowed in your country? There is many research, but to my knowledge very few countries allow the legal use of phages

Are there commercial bacteriophages available in your country or are they experimental products?

E.Coli bacteria is omnipresent. it is there everywhere.
people who follow reasonable biosecurity and vaccination program for the common viral diseases know that e.coli lives with us unnoticed.
there is less scope for the presence of e.coli in borewell water drawn from 200ft and deeper, pumped to a good height and dispensed through nipple drinkers without outside contamination.
most of the feed now is steamed and dispensed through bulk tankers and mechanical feeding systems which goes to birds untouched.
sudden climate changes vaccination stress and attack of viral diseases make the bird weak and E.coli precipitates and takes an upper hand.
Farm planning and management systems should take care of sudden climate changes and proper vaccination programs besides reasonable biosecurity policies like all in all-out housing & watching the movement of men and material should keep this omnipresent GOD to be present but at its place.

A very good account on colibacillosis covering all the angles. Yes, ascending infection is a very high possibility especially in breeders under artificial insemination. In India, 95% of the breeding flocks are in cages under insemination. the hen is insemination on every 4th day and the instruments are used daily. if they are not sterilized and handled properly there is a risk of ascending infection for sure. many times this is manifested as egg yolk peritonitis.

Dr Kotaiah Talapaneni Good observation, thanks! Indeed, AI seems to lead to a higher risk of infection by Escherichia coli, Salmonella sp, and Mycoplasma gallisepticum.

Where drugs are abused resistant pathogenic strains emerge. E. Coli is opportunistic pathogens. They become pathogenic when subjected to a lot of predisposing factors that already enumerated. The amino penicillins like ampicillin and amoxicillin are good threat to the pathogens. Areas where m. gallisepticum are recurrent based on poor parental and grand parental raising, makes the disease to be prevalent with disease complexed syndromes. Unfortunately, most of the revised pathogenic strains based on physical and chemical induced mutation subsists in poor sanitary drinking waters. Such strains are very difficult to treat unless with alternate medications. In good discuss biosecurity is the keyword especially in drinking water and feeds. Developing countries are worst hit by this disease because of less advanced poultry technology.

Any avian respiratory disease that causes ciliostasis of the respiratory tract gives APEC organisms greater opportunity to invade and wreak havoc eg Mycoplasmosis , aspergilosis etc
