Bacteriophage-typing designations of Salmonella typhimuriumSUMMARY The 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.

The isolation and classification of Tern virus: Influenza Virus A/Tern/South Africa/1961The aetiological agent of an epizootic among Common Terns (Sterna hirundo ) in South Africa in 1961 was isolated from several sick birds and named Tern virus. It was classified on the basis of antigenic and morphological properties as a strain of avian influenza virus, Myxovirus influenzae A/Tern/South Africa/1961. The strain-specific antigen of Tern virus was unr... ...

Age-related changes in the rate of disease transmission: implications for the design of vaccination programmesSUMMARY Mathematical 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... ...

The Prevention of Compressed-air Illness1. The time in which an animal or man exposed to compressed air becomes saturated with nitrogen varies in different parts of the body from a few minutes to several hours. The progress of saturation follows in general the line of a logarithmic curve and is approximately complete in about five hours in man and in a goat in about three hours. 2. The curve of desaturation after... ...

Clostridium welchiifood poisoning1. Outbreaks of mild food poisoning have been investigated in which heat-resistantCl. welchii appeared 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. welchii concerned are only feebly ... ...

Lactose-Fermenting Bacteria in FaecesThe following experiments were begun with the object of ascertaining the distribution in nature of certain lactose-fermenting organisms which are by some grouped under the name Bacillus coli , but by others are regarded as belonging to a different class of organisms; a difference of opinion which is most probably the principal factor in causing the value of ...

Campylobacter enteritis – the first five yearsFive years have passed sinceCampylobacter jejuni became 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...

The use of live vaccines in experimental Salmonella gallinarum infection in chickens with observations on their interference effect1. A good immunity was produced in chickens against oral infection with Salm. gallinarum by the use of either of two live attenuated vaccines, one smooth, 9S and one rough, 9R. Dead vaccines had little or no effect. 2. The immunity possessed by chickens vaccinated with 9R at 7 weeks of age commenced to wane 12 weeks later. Chickens similarly vacci... ...

Microneutralization tests for serological typing and subtyping of foot-and-mouth disease virus strainsSUMMARY A 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... ...

Klebsiella serotyping by counter-current immunoelectrophoresisSummary The development of aKlebsiella serotyping method by counter-current immunoelectrophoresis (CIE) is described. Antisera were prepared against the capsular antigens of 72 type strains and tested for the specificity and strength of their precipitin reactions with antigens from homologous and heterologous serotypes. All ... ...
