Technical Considerations of Cholera Vaccines and Some Results of Cholera- El Tor Mass Immunization

Among the bacterial vaccines used for prophylactic measures, Cholera vaccme does not give a complete protection or a satisfactory mass vaccinations result compared with other biologics used for the prevention of other human infectious diseases. This relative failure is partly due to the fact that cholera used to be, for many centuries, a problem in a limited part of Asia and from this asian foc...

Isolation of Hemagglutinative Non-el Tor Cholera Vibrios.

During 1963, El Tor cholera spread through Thailand and Burma, and finally appeared in the Chittagong area of East Pakistan in November (Yen et al., East Pakistan MIed. J. 8:22, 1964). With disease caused by the El Tor vibrio within 80 km of areas under study by this laboratory, all vibrio isolates which agglutinated in cholera antisera were screened by the chicken erythrocyte agglutination tes...

Cholera vaccines.

Cholera causes significant morbidity and mortality worldwide. For travelers, the risk of developing cholera per month of stay in a developing country is approximately 0.001%-0.01%, and cholera may present as traveler's diarrhea. In the United States, only a poorly tolerated, marginally effective, parenterally administered, phenol-inactivated vaccine is available. Outside the United States, 2 ad...

Cholera outbreaks in the El Tor biotype era and the impact of the new El Tor variants.

Vibrio cholerae O1, the causative agent of the disease cholera, has two biotypes namely the classical and El Tor. Biotype is a subspecific taxonomic classification of V. cholerae O1. Differentiation of V. cholerae strains into biotype does not alter the clinical management of cholera but is of immense public health and epidemiological importance in identifying the source and spread of infection...
