The study examines the levels of contamination of domestic water sources in Maiduguri Metropolis area of Borno State based on their physicochemical and bacteriological properties.  It was informed by the global concern on good drinking water quality which is an indicator of development level; hence the focus on domestic water sources to ascertain safety as water from unhygienic sources pose serious health challenges. The study dwelt on physicochemical and bacteriological parameters believed to have health implications. Experimental design was adopted, where water samples derived from four different sources i.e. from treated surface water, deep boreholes, wash boreholes and harvested rainwater were tested in the laboratory for  pH, total dissolved solids (TDS), total hardness (TH), aluminium (Al), arsenic (As), cadmium (Cd), chromium (Cr), cupper (Cu), cyanide (Cn), lead (Pb), fluoride (Fl) and nitrate (NO3). Also tested were faecal coliform (E. coli) and total coliform counts in the samples. The results showed that levels of physicochemical parameters are within the acceptable limit of WHO mostly in samples from deep boreholes and treated surface water sources. Samples from wash boreholes and harvested rainwater show escalated levels of some of the physicochemical parameters. The two sources also did not yield zero E. coli count. The study concludes that water from wash boreholes and harvested rainwater sources potent health risk. Thorough epidemiological study to determine health implications of drinking water from wash boreholes and harvested rainwater in the study area was offered as recommendation.Keywords: Domestic Water, Contamination, Boreholes, Diseases

Free Living Amoeba

Studies on waterborne parasites from natural environment and domestic water sources in Uganda are very scarce and unpublished. Water dwelling free-living amoebae (FLA) of the genus Acanthamoeba, Hartmannella, and Naegleria are often responsible for causing morbidities and mortalities in individuals with recent contact with contaminated water, but their presence in Uganda’s public water supply sources is not known. We cultivated and genotyped FLA from natural and domestic water from Queen Elizabeth Protected Area (QEPA) and Kampala (KLA). The cultivated parasites were observed microscopically and recorded. The overall prevalence of FLA in QEPA (Acanthamoeba spp., 35%; Hartmannella spp., 18.9%; Naegleria spp., 13.5%) and KLA (Acanthamoeba spp., 28.3%; Naegleria spp., 16.6%; Hartmannella spp., 23.1%) were not significantly different. The highest prevalence across water sources in QEPA and KLA was observed for Acanthamoeba spp., followed by Hartmannella spp., and Naegleria spp. Overall FLA mean (±SE) and mean (±SE) across water sources were highest for Acanthamoeba spp. compared to other FLA but were not statistically significant (p > 0.05). Analysis of the FLA sequences produced 1 Cercomonas, 1 Nuclearia, 1 Bodomorpha, 2 Hartmannella, 5 Echinamoeba, and 7 Acanthamoeba partial sequences, indicating a muliplicity of water contaminants that need to be controlled by proper water treatment.

Neurological Infections

Free living amoebae (FLA) are amphizoic protozoa that are ubiquitous in nature. Infection with FLA may result in neurological, ocular and skin infections. Exposure to Acanthamoeba occurs frequently through water contact and knowledge of the presence of the organisms in water sources is important in understanding transmission dynamics. The distribution of Acanthamoeba was studied in recreational and domestic water samples collected from across Jamaica. Morphological assessment and polymerase chain reaction revealed Acanthamoeba spp. isolates in 50.6% (42/83) and 17.3% (14/81) of recreational and domestic water, respectively. Sequencing of the DF3 region of the 18S rDNA resulted in the identification of genotypes T3, T4, T5, T10 and T11 corresponding to Acanthamoeba spp: A. griffini, A. triangularis, A. lenticulata, A. culbertsoni and A. hatchetti. Moreover, T4 was the most frequently isolated genotype in both recreational and domestic water. Thermotolerance and osmotolerance assays indicated that most isolates were potentially pathogenic. This is the first report of T3 and T10 genotypes in the Caribbean and the first report of these Acanthamoeba spp. in Jamaican waters. The study shows that there is potential risk of infection to contact wearers who practise poor lens care. Further, Acanthamoeba should be considered as a cause of neurological infections in Jamaica.
