Abstract
Callitroga hominivorax, the screw-worm, is well recognized as a cause of weight losses in cattle and other domestic animals. Borgstrom (1938) reported weakness, emaciation, and loss of appetite in guinea pigs infested with this parasite; these symptoms were less severe in reinfestations. Laake and Smith (1939) confirmed these findings and reported that abortion usually resulted in guinea pigs with heavy infestations (2 larvae per 100 g body weight). Borgstrom stated that by the 5th day of infestation the average leucocyte count had dropped from a normal of from 10,000-13,000 to 5,800-7,000, averaging 6,500. After this time the leucocyte count rapidly rose and became normal on the eighth day. Micks and Calma (1952), on the other hand, reported an elevation in white blood cell counts in human cases of nasal infestation by the screw-worm. In these cases, temperature peaks of 103? to 104? F are also common.
