ABSTRACT: A microbial study was conducted from wastewater
soils of hospitals in Aizawl, Mizoram, India which were in existence for a
longtime. The isolated bacteria from the wastewater soils were found to be
mainly of Morganella morganii and Bacillus cereus and these isolated
bacteria were found to be very resistant to a wide range of antibiotics and
heavy metals. Antibiotics that were used for treating infections caused by
these bacteria like chloramphenicol and ciprofloxacin were also found to be
insensitive. The degree of resistance was also very high when compared to
earlier reports of antibiotic resistance observed in the corresponding
bacteria. Our results suggested that the high degree of resistance is probably
conferred by the continued exposure to antibiotics from hospital waste leading
to a selected population of highly antibiotics-resistant bacteria.
