Abstract
This study was performed from February to April 2006; several visits were made to abattoirs in the north of Iran for Hypoderma spp infestation. Necropsy inspection of slaughtered and skinned animals were carried out by examination of the inner skin surface and subcutaneous tissues. Warbles were isolated by squeezing nodules from subcutaneous tissues. In the case of abscess presence, aseptic sample were taken from abscesses. The parasitological and bacteriological examinations were performed on the samples. The results indicated that 104 out of 958 of slaughtered animals were infested to Hypoderma spp in which 48 (46.15 %), 34 (32.69 %) and 22 (21.15 %) were infested to Hypoderma bovis, Hypoderma lineatum and both species, respectively. Following bacterial analysis, the following bacteria were isolated: Escherichia coli, Streptococcus pyogenes, Staphylococcus aureus, Staphylococcus epidermidis and Klebsiella pneumonia.
