HORTICULTURE

Detailed explanation-1: -Houseflies have an affinity for human excrement and, as documented by bacteriologic culture of trapped flies, become contaminated with Shigella organisms following contact with infected human feces. The inoculum required to transmit shigellosis is only 10-10(2).

Detailed explanation-2: -The findings indicate that houseflies, acting as mechanical vectors, transmit Shigella (and possibly enterotoxigenic E coli) diarrhoeal infections.

Detailed explanation-3: -House flies are strongly suspected of transmitting at least 65 diseases to humans, including typhoid fever, dysentery, cholera, poliomyelitis, yaws, anthrax, tularemia, leprosy and tuberculosis.

Detailed explanation-4: -The most prevalent bacterium detected in the microbiome of houseflies is the Psychrobacter sp. PRwf-1, present in 73.6% of the individuals analysed (Fig.
