Abstract:
INTRODUCTION:
Fungal infections have emerged worldwide. Cockroaches have been proved vectors of medically fungi.
METHODS:
A systematic meta-analysis review about cockroach fungal contamination was investigated. Relevant topics were collected between January 2016 and January 2017. After a preliminary review among 392 collected papers, 156 were selected to become part of the detailed systematic meta-analysis review.
RESULTS:
Cockroaches contaminated to 38 fungi species belonging to 19 families and 12 orders. About 38, 25 and 13 fungal species were recovered from the American, German and brown-banded cockroaches, respectively with a variety of medical importance. Except the fungi isolated from German and brown-banded cockroaches, 15 species have been isolated only from the American cockroaches. The global world mean and trend of cockroach fungal contamination were 84.1 and 50.6-100%, respectively in the human dwelling environments. There is a significant difference between cockroach fungal contamination in the urban and rural environments (P<0.05) without a significant difference between hospital and household environments (P>0.05). The external and internal cockroach fungal contamination is more dangerous than entire surfaces, while the internal is more dangerous than the external surface. The German and brown-banded cockroach fungal contamination are more dangerous than the American cockroaches in the hospital environments.
CONCLUSION:
The study indicates that globally cockroach fungal contamination has been increased recognizing as agents of human infections and associating with high morbidity and mortality in immune-compromised patients. These facts, along with insecticide resistance emergence and increasing globally cockroach infestation, reveal importance of cockroaches and need for their control more than ever.
