Article Abstract:
Research was conducted to examine the effects on the indigenous bacterial microflora of sewage released into sewers of effluents from hospitals or other sources of antibiotic-containing effluent such as a pharmaceutical plant. Acinetobacter spp. was used as bacterial indicators of antibiotic resistance to investigate whether the release of wastewater from such sources could increase the number of antibiotic-resistant bacteria in sewers. Results indicate that the release of wastewater from the hospital was related to the increase in the prevalence of oxytetracycline resistance.

Article Abstract:
Escherichia coli strains from sows and pigs exhibit multiple antibiotic resistance mechanisms. This was evident in an experiment comparing patterns between pigs of various ages and extent of antibiotic use. It was found that resistance patterns differ between farm types and pigs of varying ages, implying that pig age and degree of antibiotic use exert an influence on antibiotic resistance of fecal Escherichia coli.

Article Abstract:
Researchers document extensive transfer of genes for antibiotic resistance between gram-positive and gram-negative bacteria in the colon. Genes for drug resistance in colon bacteria were even found in healthy people in the community who had no recent history of antibiotic use.
