Frequency of Bacterial and Viral Infections in the Environment of Different Areas of Karachi
Karachi, the capital of Sindh is the largest city with the health issues caused by air and water
pollution, improper sanitation and unhygienic measures. This study focuses on survey the human
health issues of bacterial and viral pathogens in different age groups of the male and female
patients. A total of 305 and 259 (total 564) different samples of stool and blood of the male and
female patients of 1-15; 16-30, 31-45 and 46-60 age groups from Liyari (LY), Baldia Town (BT),
Orangi Town (OT), Sachal Goth (SCG), Sohrab Goth (SBG) and Korangi Industrial Area (KIA)
were collected to determine the occurrence (percentage) of major diseases prevailing in the
environment of Karachi. In this study, the bacterial isolates were identified by culturing on Blood
agar, MacConkey’s agar and Pylori agar for E.coli, Shigella dysentery and Helicobacter pylori
respectively. HBVsAg method was used to detect the presence of antibodies in patients’ serum.
Our results revealed the greater prevalence of E. coli / Shigella dysentery infection in females and
males at SCG; Helicobacter pylori infection in at BT in males and no infection was observed in
females and HBV infection resulted at greater ration in both genders at OT in 1-15 years of age
respectfully. The observation of 16-30 years of age groups revealed greater occurrence of E. coli /
Shigella dysentery SCG in males and in females at LY; Helicobacter pylori infection at LY in
males and in females at KIA, whereas HBV infection at LY and KIA in males and females,
respectively. The age groups 31-45 years showed greater incidence of E. coli / Shigella dysentery
infection at LY and KIA; Helicobacter pylori infection at SCH and OT in females and males,
whereas HBV resulted greatly at LY in males and in females at LY and OT, respectively. The
findings of E. coli / Shigella dysentery; Helicobacter pylori infections revealed the greater
incidence at LY, BT, LY, BT in males and females, respectively, whereas the HBV was observed
at KIA in both genders of 46-60 years of age groups. These observations are the alarming increase
in the risk factors and the dissemination of infections with greater morbidity and mortality rates in
