Abstract
The common housefly (Musca domestica)
is a vector of various microbial and parasitic pathogens. In this study, Klebsiella
pneumoniae strains were isolated from houseflies caught in the premises of
a public market, school canteens and hospital in Tacloban City, province of
Leyte, Philippines. Standard cultivation techniques for enteric bacilli were
followed while the identification and antibiotic sensitivity testing were done
using the Vitek 2 automated system. Results showed that out of 120 houseflies
caught, only 16 (13.3%) had isolates of Klebsiella pneumoniae. These
isolates were sensitive to Cefrofloxacin, Ceftazidime, Ceftriaxone, Gentamicin,
Imipenem, Meropenem, Piperacillin/Tazobactam, and
Trimethoprim/Sulfamethoxazole, intermediate to Colistin and resistant to
Ampicillin. This study proved that in our city, there are houseflies serving as
vector of K. pneumoniae that are either sensitive or resistant to
commonly prescribed antibiotics.
