Comparative Analysis of the Prevalence of Bacteria Pathogens Obtained from Rat and Cockroach Faeces
The study was aimed at comparatively analyzing the bacteria pathogens presence in rat faeces (RF) and cockroach faeces (CF) so as to ascertain their implication as potential vectors of disease transmission. Samples of RF and CF were examined for total heterotrophic bacteria counts (THBC) and total coliform bacteria counts (TCBC). Results obtained indicated that RF had THBC that ranged from 5.0×104 CFU/g to 6.1×104 CFU/g, while CF recorded THBC which ranged between 6.0×105 CFU/g and 8.4×104 CFU/g respectively. CF had high THBC of Log10 4.9 when compared to that of RF which gave Log10 THBC of 4.8. Results further shown that RF had TCBC which ranged from 1.3×105 CFU/g to 1.6×105 CFU/g, while CF gave TCBC ranging from 1.6×105 CFU/g to 1.9×105 CFU/g. The highest prevalent bacterium in RF was Bacillus sp. 33 (23.9%). This was followed by Klebsiella sp. 32 (23.2%), Serratia sp. 27 (19.6%), Escherichia sp. 17 (12.3%) and then Proteus sp. 16 (11.6%) while the least prevalent was Pseudomonas sp. 13 (9.4%). CF contained a significantly (p<0.05) higher prevalence of bacteria than RF and with low total heterotrophic bacteria population when compared to its total coliform bacteria counterpart in both rat and cockroach feaces. The presence of these bacteria in the feaces of rats and cockroaches indicates possible presence of pathogens of public health risk. Businesses and households handling food should adhere to basic food hygiene to help ensure that food and beverage products prepared and consumed at homes are free from rat and cockroach infestation to prevent outbreak of foodborne illnesses.
