each y,b season we see an increase in desease involving the bacteria e,coli. e coli is a normal inhabitant of the digestive system of pigeons, it has desease potential, but usually needs a predisposing condition to allow it the oppertunity to cause infection, several things can "open the door"for e coli to cause desease,
stress ,vieal infections intestinal parasites, nd other irritantsin the bowel such as chemicals consumed while feilding , the usual factor of ybs is adenovirus, it beginsappearing when birds are mixed . either in training , races or when accumulating birdsfrom various sources
the adenovirus by itself will not cause desease, but in the presence of e,coli, it allows the e,coli, to cause desease. treating e coli infection usually eliminates symtoms although it does nothing for the adenovirus infection, this is usually conquered by the birds own immunity system with time, there is not an effective vaccine for adenovirus. so we must let it run its course as we try to control the e coli. during outbreaks
usually during outbreaks ofe coli infection ,, we use a broad spectrum antibiotic such as amoxicillin to control it ,,,,antibiotics will not prevent it so only to be used during an out break, the symtoms usually include vomiting in some birds , abnormal droppings or loosedropings and lethargy
the birds will not train or race well during uncontrolled outbreak, a feacal culture and sensitivity study will allow one to use the correctantibioticto use, often we just go with one that has a good track record ,,and that has little or no effect on the birds allowing one to continue training etc,
amoxicillin is my first choice of anti biotic when" shooting from the hip" it is gentle on the pigeon and is the least expensive of the good antibiotics use 3 grams per gallon for about 7 days , re- treatment is often necesssary as things may deteriorate within weeks after training , as the viral infection spreads through the flock, do not forget not to use antibiotics as a preventative, they will not work as a preventative but will only allow the bacteria to become resistant to it ,,then it wont work when we really need it ,,,,,,dr david e. marx d.v.m,,, by doc white m,a,d, ;D ;D ;D,, seriously maybe of some help to fanciers as yb racing starts
