Abstract

Seventy percent of the earth is occupied by oceans. Forty percent of the world inhabitants are living along
the coastline of the oceans. Marine microorganisms have been associated with various processes in the
ocean with 50% of global primary production occurring in the ocean and carried out by marine bacterial
metabolisms of chemical elements. Divers infectious diseases affecting both human and animals originate
from aquatic sources especially water and sediment most of which occur in developing countries as a result
of industrial and anthropogenic activities in coastal areas while the level of contamination influences pathogenicity
of the prevailing pathogens contamination. Aeromonas and Vibrio species are aquatic microorganisms
and share similar characteristics. They cause diseases in both human and aquatic animals. They are
also prevalent in coastal areas. Virulence factors are utilized by bacteria to escape host immune system, to
establish diseases and resist antibiotics. Most common virulence factors among bacteria include protease,
lysis of red blood cells, motility, and biofilm formation. There has been a global increase in emerging and
re-emergence of virulence bacteria species. Among the key factors attributed to this trend is resistance to
antibiotics, possession of new virulence genes through horizontal gene transfer from the environment or
bacterial stress. Study on Aeromonas and Vibrio species has grown widely in the past decades due to unusual
antibiotics resistance and virulence factors displayed by these bacteria hence comparative study on
the occurrence, prevalence, putative virulence factors and antibiotics resistance of Aeromonas and Vibrio
species is therefore required.
