Abstract
The present study used the Chemiluminescent Microparticle Immunoassay (CMIA) to examine the alterations in pituitary- thyroid function, in camels infected with third instar larvae of Cephalopina titillator, by measuring the levels of triiodothyronine (T3) and thyroxine (T4) of the thyroid gland and level of thyroid stimulating hormone (TSH) of the pituitary gland. The results indicated that the infection of camels by larvae of the nasal bot fly caused a case of hypothyroidism. This was evidenced from the declines recorded in blood levels of T3 and T4. Also the data obtained point to the occurrence of a parallel decrease in the level of blood TSH. It appears that the depressed release of TSH during infection with C. titillator together with the subsequent decline in T3 and T4 levels from thyroid gland, might reflect the direct effect of infection on pituitary gland, and suggest decreased synthesis of T3 and T4 in response to larval infection of the nasal bot fly.
