ISOLATION OF POTENTIALLY PATHOGENIC BACTERIA FROM THE INTERNAL SUDANESE COASTAL WATERS OF PORT SUDAN

Abstract

This study was carried out to isolate and identify some species of
opportunistic pathogenic bacteria that may be present in the inner
Sudanese coastal waters of Port Sudan (Khour Salalab). From this area,
10 sea water samples were collected and used for isolation and
identification of possible potentially pathogenic bacteria which increases
the chances of the presence of frank pathogens.
Water samples were inoculated in Selenite broth and after an
incubation period of 48hrs at 37ºC, streaked onto MacConkey's and
Salmonella-Shigella agar then the pure colonies were picked and
identified.
A variety of opportunistic pathogens were isolated which were:
Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Citrobacter
freundii, Pseudomonas aeruginosa, Pseudomonas alcaligenis,
Pseudomonas fluoresens, Streptococcus faecalis and Vibrio anguillarum
and this increases the possibility of the presence of frank pathogens.
The study showed that more efforts should be made to reduce marine
pollution and improve water sources management and a need for strategy
to improve general and environmental health. there are no records about
the number of swimmers and swimming-related diseases in this area.
However, due to the develop of tourism and its related activities, chances
of swimming related diseases are likely to increase.
