Contamination of cockroaches (Insecta: Blattaria) to medically fungi: A systematic review and meta-analysis

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.
