Abstract

The antibiotic resistance conjugative plasmids of Salm. typhimurium prolonged the lag-phase of coli bacteria. It was shown that the plasmids had a significant effect on the generation period either prolonging or shortening it. No correlation between the number of the antibiotic resistance determinants and resistance to separate antibiotics and the growth indices was found. The chromosome mutations of resistance to rifampicin and nalidixic acid in the strain of E. coli studied had no effect on duration of the lag-phase but resulted in shortening of the generation period.

Allergy & Infectious Diseases

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.
