  • Resistance towards the responsible pathogens are also seen in developed countries. The situation has worsened often due to limited resource available to investigate and provide reliable susceptibility data on which rational treatments can be based as well as means to optimize the use of antimicrobial agents. The emergence of multi-drug-resistant isolates in tuberculosis, acute respiratory infections and diarrhea, often referred to as diseases of poverty, has had its greatest toll in developing countries.

  • Harrison's Internal Medicine Chapter 131. Diphtheria and Other Infections Caused by Corynebacteria and Related Species Diphtheria Diphtheria is a nasopharyngeal and skin infection caused by Corynebacterium diphtheriae. Toxigenic strains of C. diphtheriae produce a protein toxin that causes systemic toxicity, myocarditis, and polyneuropathy. The toxin is associated with the formation of pseudomembranes in the pharynx during respiratory diphtheria. While toxigenic strains most frequently cause pharyngeal diphtheria, nontoxigenic strains commonly cause cutaneous disease.

  • Pathogenesis and Immunology Diphtheria toxin, produced by toxigenic strains of C. diphtheriae, is the primary virulence factor in clinical disease. The toxin is synthesized in precursor form; is released as a 535-amino-acid, single-chain protein; and has an LD50 of ~100 ng/kg of body weight. The toxin is produced in the pseudomembranous lesion and is taken up into the bloodstream, through which it is distributed to all organ systems.

  • Population displacement caused by cyclone damage and flooding can result in overcrowding in resettlement areas, raising the risk of transmission of certain communicable diseases. Measles (see section below on vaccine-preventable diseases), ARI, diphtheria and pertussis are transmitted from person to person through respiratory droplets, and the risks are increased in situations of forced relocation to shared areas which are overcrowded and have inadequate ventilation. Overcrowding can also increase the likelihood of transmission of meningitis, waterborne and vector-borne diseases.
