Abstract

KAPPEL, Henrique Borges; OLIVEIRA, Adriana Gonçalves; SILVA, Paulo Roberto da  and  PELLI, Afonso. Non-biting flying insects as carriers of pathogenic bacteria in a Brazilian hospital. Rev. Soc. Bras. Med. Trop. [online]. 2013, vol.46, n.2, pp.234-236. ISSN 0037-8682.  http://dx.doi.org/10.1590/0037-8682-1173-2013.

Introduction

Insects have been described as mechanical vectors of nosocomial infections.

Methods

Non-biting flying insects were collected inside a pediatric ward and neonatal-intensive care unit (ICU) of a Brazilian tertiary hospital.

Results

Most (86.4%) of them were found to carry one or more species of bacteria on their external surfaces. The bacteria isolated were Gram-positive bacilli (68.2%) or cocci (40.9%), and Gram-negative bacilli (18.2%).

Conclusions

Insects collected inside a hospital were carrying pathogenic bacteria; therefore, one must consider the possibility they may act as mechanical vectors of infections, in especially for debilitated or immune-compromised patients in the hospital environments where the insects were collected.
