POTENTIAL OF COCKROACHES IN TRANSMITTING PATHOGENIC ORGANISMS



Ibrahim, A. W. and Cece, M. A. on 06/01/2017

A study to determine the possible role of cockroaches as a transmitter of pathogenic organisms was undertaken. The study was carried out in residential houses of Ara’a village, Moro Lacal Government Area of Kwara State, Nigeria. One hundred and eighty cockroaches were collected from different residential houses in three sites, toilets, kitchens and rooms (living rooms / bed rooms). The pathogenic organisms were isolated and identified from external surface of cockroaches, using standard methods. The results showed that 170 (94.4%) of coackroaches harboured pathogenic organisms, of these 54.4% were parasites including Entamoeba histolytical, Entamoeba coli, Balanfidium coli, Isopsora beli and Cryptostoridium sp. 88.3% were bacteria including E. coli, Klebsiela pneumoniae, Proteus vulgaris and Proteus mirabilis and 94.4% were fungi including Candida sp., Mucor sp., Rhizopus sp., Aspergillus sp. And Penicillum Sp. Therefore as cockroaches continue to constitute important reservoir for infectious pathogen, control measure instituted in toilet, kitchen and rooms could substantially minimize the spread of some of these infectious disease in human neighbourhoods where cockroaches are associated.
