aS i HAVE READ THIS THRU AND AM STILL WONDERING HOW DOES THE CHICKEN GET OVER THE FUNGAL INFECTION?
AND DOES IT ALWAYS BOTHER THE CHICKEN?
thanks for any information as I do not understand how the crop gets rid of the fungal infection
Candida albicans (the usual cause of a "yeast infection" aka "thrush") exists in the system normally as a single celled fungal organism. The term "yeast" is just really used as a vernacular term.
With certain body conditions (most notably temperature or the lack of competition from other more beneficial flora - like beneficial bacteria)*, it divides into a multicelled form (a multicellular mycelium)and then is classified as a fungus. That's when it's a problem. When it morphs, it develops threadlike filaments (mycelia). Those filaments burrow into the intestinal wall, allowing substances to pass into the blood system (like toxins, more candida, undigested food particles which thereafter cause a reaction in the body to them).
Nystatin is an anti-fungal agent which kills C. albicans with contact (thus the preference for an empty crop). So with a continued application of nystatin, the fungal cell chains will decrease. The addition of probiotics is a most important step in the treatment as there needs to be competition to prevent the C. albicans from morphing into the pathogenic form. Lactobacilli and Bifidobacteria are notable for this in tandem.
Technically, ever chicken has C. albicans naturally occuring in its digestive tract, just not usually in the pathogenic form until conditions are right. *And that is one of the many reasons why I am a big proponent of probiotics for stressed birds and young birds whose bacterial colonies are just developing. Any stress causes a decrease in the natural beneficial flora (bacteria) in a bird. That leaves the window open for opportunistic organisms (bad bacteria, fungi) to bloom. So I don't allow them the opportunity and encourage others to do the same.
I hope this helps.
