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
Microneutralization tests for serological typing and subtyping of foot-and-mouth disease virus strainsCambridge University Press (CUP) - Tập 81 Số 1 - Trang 107-123 - 1978
Mark M. Rweyemamu, J. C. Booth, M. Head, T. W. F. Pay
SUMMARYA microneutralization test for serotyping of FMD viruses is described. It is based on earlier observations by Booth, Rweyemamu & Pay (1978) that dose-response relationships in quantal microneutralizations often deviated from linearity. The typing test described therefore utilizes undiluted virus preparations. In about 90% of samples a positive typing was...... hiện toàn bộ
Campylobacter enteritis – the first five yearsCambridge University Press (CUP) - Tập 89 Số 2 - Trang 175-184 - 1982
M. B. Skirrow
Five years have passed sinceCampylobacter jejunibecame generally recognized as a common cause of acute diarrhoea (Skirrow, 1977) – although the essential scientific discovery which led to this had been made several years earlier (Butzleret al.1973) – so this is an appropriate time to take stock of what has happened in that time and cons...
A most probable number method for estimating small numbers of campylobacters in waterCambridge University Press (CUP) - Tập 89 Số 2 - Trang 185-190 - 1982
F. J. Bolton, P. M. Hinchliffe, D. B. Coates, L. Robertson
SUMMARYA most probable number (MPN) method capable of estimating as few as ten campylobacters per 100 ml of water is described. The method gave results close to those obtained by the viable count method of Miles, Misra & Irwin (1938) with graded suspensions ofCampylobacter jejuni. The method was used to test raw water samples: counts ...... hiện toàn bộ
The use of Preston enrichment broth for the isolation of ‘thermophilic’ campylobacters from waterCambridge University Press (CUP) - Tập 92 Số 1 - Trang 45-51 - 1984
C D Ribeiro, T. H. Price
SUMMARYThe application of Preston enrichment broth to isolation of ‘thermophilic’ campylobacters from water has been investigated. Enrichment substantially increased the yield of such organisms. The optimum timing for subculturing the broth was after 48 h incubation. Despite the addition of aerotolerant supplement to the broth the number and variety of isolates was...... hiện toàn bộ
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
