Abstract
Cutaneous lesions caused by Ornithonyssus bacoti are misdiagnosed as other infection with bacteria or fungi or as allergies . Dermatitis in the persons working in animal house was infested with O. bacoti is reported in this study .A small number of studies confirmed that the Ornithonyssus species may cause dermatitis in human. The physical examination for patients showed separate papules scattered over their ( arms, shoulder ,legs) , restlessness and urticaria -like dermatitis Microscopic examination was performed for 80 parasite from rat in animal house and 20 from clothing of researchers that worked in animal house and confirmed by PCR amplification
Highlights
Ornithonyssus bacoti is a parasite can infect laboratory rodent colonies and have wide host range
DNA extraction in animal house of Kufa University in the DNA was extracted from mites by using province of Najaf AL Ashraf .The student Geneaid Genomic DNA extraction tissue kit was suffering from severe itching and and completed the steps based on company papular urticaria and their general health guidelines
The study revealed that 100 specimens (100%) get positive result for Polymerase Chain Reaction (PCR),while there were no specimens with negative results, were Ornithonyssus bacoti detected in all specimens
Summary
Ornithonyssus bacoti is a parasite can infect laboratory rodent colonies and have wide host range. This parasite can irregularly infest humans when skin contact between them occur (Beck,2008). Baumstark et al,(2007) mentioned that the information is inadequately existing for distribution and occurrence of Ornithonyssus bacoti on pet rodents in worldwide. The insufficiency of information, due in part to misdiagnosis makes the disease seem less universal than it is. Systemic diseases or use of any drugs. Sang et al,(2013) said that the Mites Collection: Mites collection was consulted physician consider cutaneous occurred by 2 ways ,the first by brushing the lesions due to other causes , reflection of a anesthetized rodent hairs(fed, red/brown in parasitic cause subsequent to finding color and sluggishly motile).The second , the parasites in the living or working place or parasites were picked up from personnel when symptomatic therapies were failed.
