Multidrug Resistant Escherichia coli Isolated from Asymptomatic School Going Children in Kibera Slum, Kenya | Chapter 07 | Theory and Applications of Microbiology and Biotechnology Vol. 2
Pathogenic Escherichia coli are of
different types, currently grouped into six groups depending on the virulence
gene(s) they possess. This study isolated pathogenic E. coli from 580 stool
samples obtained in the month of August, 2016. The samples were obtained from
asymptomatic school going children in one of the biggest urban slums in Kenya.
Ten primary schools were randomly sampled and 40 to 80 stool samples collected
from each school depending on the school population. Both gender and age were
considered when sampling. Data obtained was analysed using single factor ANOVA
to test association between school location and levels of infection with
pathogenic bacteria. A total of 244 (17%) samples had E. coli. Out of these, 38
(6.5%) were shown to have one or a combination of the pathogenic genes, namely:
ipaH, virF, st2, daaE, eae, aafII, stx1, bfp, lt and stII and were thus
classified into seven groups. Of the pathogenic isolates 35 (21.2%) were
multidrug resistant. There was an association between school location and the
prevalence of pathogenic bacteria. In conclusion, asymptomatic school going
children in the slum were found to be infected with multidrug resistant
pathogenic E. coli.
