From home-made oral rehydration solutions (ORS), the identified bacterial strains from a total of 1880
bacterial isolates (1010 from granulated sugar and 870 from table salt) using the conventional taxonomic
tools were Bacillus cereus var. mycoides (0.57%), Bacillus subtilis (2.28%), Citrobacter sp. (1.07%),
Clostridium perfringes (14.75%), Enterobacter aerogenes (6.13%), Escherichia coli (7.44%), Klebsiella
pneumoniae (10.0%), Morganella morganii (0.78%), Proteus mirabilis (6.74%), P. vulgaris (1.68%),
Pseudomonas aeruginosa (4.67%), Salmonella entrica serovar Typhi (3.89%), Salmonella enterica serovar
Typhimurium (0.99%), Shigella dysentariae (11.0%), Staphylococcus aureus (11.98%) and Vibrio cholerae
(2.57%). The isolated fungal species from the table salt and granulated sugar samples were Aspergillus
flavus, Aspergillus fumigatus, Aspergillus niger, Botryiodiplodia sp., Candida sp. and Scopulariopsis sp.
Home-made ORS may serve as a means of transmitting gastroenteritis/diarrhoea and other infectious
microbial agents in developing countries like Nigeria
