Summary
This
study was undertaken to determine the type and estimate the prevalence
of bacterial organisms on contact surfaces of five close-to-patient
facilities in three veterinary health care settings within the Sokoto
metropolis of north-western
Nigeria. A total of 30 samples (10 from each setting) were collected
and analysed using culture, microscopy and biochemical testing.
Bacterial species isolated from samples in this study included the
following: Bacillus sp. (27.3%), Staphylococcus aureus
(15.9%), Listeria sp. (13.6%), Streptococcus sp. (11.4%),
Salmonella sp. (6.8%), Escherichia coli (4.5%), Staphylococcus
epidermidis (4.5%), Citrobacter sp. (2.3%), Klebsiella
sp. (2.3%), Lactobacillus sp. (2.3%), Micrococcus
sp. (2.3%), Pasteurella sp. (2.3%), Proteus sp. (2.3%),
and Yersinia sp. (2.3%). A higher percentage (64.3%) of the
total bacterial isolates were zoonotic in nature and hence of public
health significance. Some pathogens have the potential of nosocomial
spread. In this study, we seek to establish the first evidence of
bacterial presence in the major veterinary health care settings
in the Sokoto region of north-western
Nigeria. Of particular interest is the hypothesis, which has not
previously been formally tested, that nosocomial infections are
especially likely to be implicated in both animals and occupational
diseases in Nigeria. It was suggested that some of these isolates
were associated with the risk of nosocomial and zoonotic infections
and hence draws attention to the need to rigorously employ standard
veterinary precautions as part of the hospital’s
infection control programme in an attempt to protect both patients
and staff from infections.
