Abstract

We studied on the antibacterial activity of gentamicin against various pathogens isolated from clinical materials mainly isolated during 1974 and 1975, comparing with other antibiotics. Beta hemolytic streptococci, pneumococci and enterococci are less susceptible to gentamicin than staphylococci. Staph, aureus and Staph. epidermidis resistant to various antibiotics are very susceptible to gentamicin, and no resistant strain to this drug was found. Haemophilus influenzae, H. parainfluenzae and H. parahaemolyticus are very susceptible to gentamicin, and there is no resistant strain to this drug. Escherichia coli, Klebsiella, Citrobacter, Serratia and five species of Proteus are more susceptible to gentamicin and tobramycin than dibekacin and amikacin. A few resistant or less susceptible strains to gentamicin are found in E. coli, Citrobacerr, Serratia, Pr. morganii and Pr. rettgeri. Pr. inconstans is less susceptible to gentamicin than other species of Proteus. Antibacterial activity of gentamicin against Pseudomonas aeruginosa is very strong, but dibekacin and tobramycin are stronger. Gentamicin-resistant strains of Pseudomonas aeruginosa are now rather few.

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.
