Changes in the nuclear structure of bacteria, particularly during spore formationCambridge University Press (CUP) - Tập 44 Số 2 - Trang 99-108 - 1945
E. Klieneberger‐Nobel
Changes of nuclear structure in bacteria have been studied by means of the hydrochloric acid-Giemsa method which produces brilliantly stained specimens and can be carried out with almost the same ease as some of the ordinary routine staining techniques.The nuclear changes in the four spore-bearing organisms studied are outlined in Text-fig. III, to which the following numb...... hiện toàn bộ
Clostridium welchiifood poisoningCambridge University Press (CUP) - Tập 51 Số 1 - Trang 75-101 - 1953
Betty C. Hobbs, Muriel E. Smith, C. L. Oakley, G. Harriet Warrack, J. C. Cruickshank
1. Outbreaks of mild food poisoning have been investigated in which heat-resistantCl. welchiiappeared to be the causative organism. The outbreaks were characterized by colic and diarrhoea without vomiting, commencing 8–20 hr. after ingestion of the contaminated food.2. The strains ofCl. welchiiconcerned are only feebly ...... hiện toàn bộ
Age-related changes in the rate of disease transmission: implications for the design of vaccination programmesCambridge University Press (CUP) - Tập 94 Số 3 - Trang 365-436 - 1985
Roy M. Anderson, Robert M. May
SUMMARYMathematical models are developed to aid in the investigation of the implications of heterogeneity in contact with infection within a community, on the design of mass vaccination programmes for the control of childhood viral and bacterial infections in developed countries. Analyses are focused on age-dependency in the rate at which individuals acquire infect...... hiện toàn bộ
The epidemiological type identification ofSerratia marcescensfrom outbreaks of infection in hospitalsCambridge University Press (CUP) - Tập 84 Số 2 - Trang 269-283 - 1980
Tyrone L. Pitt, Y J Erdman, C. Bucher
SUMMARYA study of serological, bacteriocine and phage typing ofSerratia marcescenswas made. Specific O-antisera of adequate titre were relatively simple to prepare but H-antisera exhibited many heterologous agglutination reactions amongst the type strains. Most of these cross-reactions were not reproduced when immobilization tests with H-...... hiện toàn bộ
Heredity, infection and chemoprophylaxis in rheumatic carditis: an epidemiological study of a communal settlementCambridge University Press (CUP) - Tập 58 Số 3 - Trang 263-276 - 1960
A.M. Davies, E Lazarov
1. Children and their parents in a communal settlement (kibbutz) were followed for 14 months with special regard to the influences of streptococcal carrier rate, streptococcal infections, chemotherapy and heredity on the pattern of rheumatic heart disease.2. Children with proven or probable heart disease showed the same streptococcal carrier rates as controls in spite of c...... hiện toàn bộ
Bacteriophage-typing designations of Salmonella typhimuriumCambridge University Press (CUP) - Tập 78 Số 2 - Trang 297-300 - 1977
E. S. Anderson, Linda R. Ward, Maureen J. de Saxe, Josiane De
SUMMARYThe phage-typing scheme of Callow (1959) has been extended. The original number of types was 34; this has now risen to 207. Tables are presented which show the provisional type designations and the definitive designations now being introduced.
A study of the incidence of Vibrio parahaemolyticus in Malaysian shrimp undergoing processing for exportCambridge University Press (CUP) - Tập 87 Số 3 - Trang 485-491 - 1981
D. C. Cann, Lesley Y. Taylor, Zahara Merican
SummaryThe incidence of Vibro parahaemolyticus in products of the Malaysian export shrimp processing industry was investigated through the stages from the catch to that of the cooked, peeled and frozen product. The organism was commonly found in freshly caught and landed shrimp, and could be detected by enrichment culture at all stages of...... hiện toàn bộ
