Subtypes of hepatitis B antigen among patients and symptomless carriers.

A study of the distribution of subtypes ad and ay among sera from hepatitis B antigen-positive subjects in North West England and North Wales revealed a marked contrast between symptomless carriers among whom ad predominated and patients with acute hepatitis the majority of whom were ay. Those with hepatitis associated with drug addiction or other forms of "needle transmission" were almost all of subtype ay. On the other hand in cases of "sporadic" hepatitis without evidence of parenteral exposure subtypes ad and ay are about equally distributed. These findings are similar to those reported from other countries in Northern Europe and North America. Although geographical and social factors clearly affect the distribution of the two subtypes it is suggested that the virus of subtype ay may be more readily transmitted than subtype ad by parenteral routes involving small amounts of blood.

Comparison of three serological methods for the detection of hepatitis-associated antigen.

Serum hepatitis (Australia) antigen in the sera of hepatitis patients and carriers can be detected in one and a half to three hours by crossover electrophoresis. The method is more sensitive than the immunodiffusion technique commonly employed in this field. It is of the same order of sensitivity as complement fixation but is less complicated.Crossover electrophoresis is thus the method of choice for the rapid screening of sera for hepatitis antigen; complement fixation may be used for quantitative determination of antigen in positive cases.

Outbreak of food-poisoning caused by Salmonella virchow in spit-roasted chicken.

Salmonella virchow food-poisoning acquired from eating chicken caused illness in at least 50 people who attended a tennis club function in Liverpool, and in many other people in the Merseyside area. In some cases the illness was severe, with positive blood cultures, and 35 people were admitted to hospital.The source of infection was a retail shop which received deep-frozen chickens already contaminated with S. virchow from a packing-station in Cheshire. These chickens were spit-roasted after inadequate thawing and subsequently handled under unhygienic conditions. The result was a massive build-up of salmonella contamination in the shop and in the chicken portions sold.S. virchow was isolated from over 160 patients and contacts in the Merseyside area during the outbreak and many continued to excrete the organism in the faeces after four months. Antibiotic treatment was not recomended because there was no evidence that it shortened the duration of excretion.A high rate of contamination of chickens from a packing-station by a salmonella type capable of causing serious disease in man is clearly a public health problem which cannot be ignored.The use of rotary spits for roasting chickens requires thorough investigation and appraisal, because as operated at present they evidently constitute a public health hazard.

Resistance to cloxacillin among hospital staphylococci.

Cloxacillin-resistant strains of Staphylococcus aureus were detected by their ability to grow on agar containing 1.6 mug./ml. of cloxacillin, a more reliable method than the disc-diffusion test. At Sefton General Hospital, Liverpool, between 1963 and 1965, there was an increase in the number of infections among in-patients that were caused by staphylococci resistant to cloxacillin despite the fact that use of the antibiotic was largely confined to an isolation ward for patients with staphylococcal sepsis. Although there is no evidence yet that staphylococci resistant to cloxacillin will become as common in hospital practice as those resistant to penicillin and tetracycline it is clear that there is a need for continued vigilance and measures to prevent spread of staphylococci from infected patients.
