Abstract

The increasing incidence of pneumonia caused by H. influenza and the problem of beta lactamase production (18% of strains in recent reports) are important considerations in the therapy of pneumonia. An antibiotic that is effective for these strains and other common respiratory pathogens will be useful for the therapy of pneumonia. Cefamandole nafate is a new cephalosporin antibiotic with an antimicrobial spectrum similar to cephalothin with increased activity against Escherichia coli, Proteus spp., Enterobacter spp., and Haemophilus influenzae. Seventeen patients with pneumonia presumed to be due to susceptible gram-negative organisms isolated from transtracheal aspirate or sputum were treated with 6 to 8 g/day of parenteral cefamandole nafate. Organisms isolated were Haemophilus influenzae in 6, E. coli in 3, Proteus mirabilis in 2, Klebsiella pneumoniae in 1, Serratia marcescens in 1 and mixed gram-negative rods in 4. The Serratia were resistant (MIC greater than 100 microgram/ml and 50 microgram/ml): other MIC's ranged from 0.2 to 6.2 microgram/ml; median 1.6 microgram/ml. Satisfactory clinical response (improvement in pulmonary function; resolution of infiltrate; decrease in temperature, sputum production and white count) w...Continue Reading

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.
