Serological grouping of streptococci by a slide coagglutination method.

A new method for the serological grouping of streptococci by coagglutination with specific antibodies absorbed to protein A-containing staphylococci has been assessed. A total of 242 strains of streptococci, including beta-haemolytic streptococci of groups A, B, C, F, and G, Streptococcus pneumoniae and Strep. faecalis were studied. All streptococci of groups A, B, C, and G, groupable by standard methods, were correctly grouped by coagglutination, although 7-3% showed varying degrees of cross-agglutination. Two beta-haemolytic strains of Strep. faecalis produced coagglutination with group C streptococcal reagent. The method appears to be quick, accurate, reproducible, and simple to perform.

Group B streptococci in the female genital tract.

Vaginal carriage rates of group B streptococci among 250 women attending a clinic for sexually transmitted diseases, 123 attending family planning clinics, and 110 in labour wages were 36.0%, 17-1% and 6.4% respectively. The presence of group B streptococci was not associated with a vaginal discharge or the use of oral contraceptives in the non-pregnant women, or with the isolation of Neisseria gonorrhoeae or Trichomonas vaginalis from the women attending the clinic for sexually transmitted diseases. Serotyping showed a predominance of types II and III in non-pregnant women and an overall incidence of non-typable strains of 14.8%. There was no relationship between serotype and antibacterial susceptibility.

Stimulation of growth on a deficient medium of a Klebsiella aerogenes species by sulphonamide, para-amino benzoic acid, nitrofurantoin, and some other substances.

A strain of Klebsiella aerogenes is described which was unable to grow from light inocula on 5% lysed horse blood diagnostic sensitivity test (DST) agar. It was able to grow on DST agar without added horse cells and MacConkey and nutrient agar. Growth on a deficient medium was promoted by sulphonamides and nitrofurantoin as well as by para-amino benzoic acid, para-amino salicylic acid, procaine hydrochloride, thymine, and uracil.

A clinico-pathological study of diabetic foot ulcers.

During a 32-month period 94 foot ulcers in 54 diabetic patients aged 38-90 years (mean 64 years) were managed in a specialist foot clinic. Fifty-six percent were men, and they were significantly younger than women; 46% were taking insulin. Mean duration of diabetes was 13.4 years. Comparison with controls revealed a higher prevalence (p less than 0.01) of retinopathy (60% vs 23%), neuropathy (89% vs 31%), vasculopathy (71% vs 34%), arterial calcification (31% vs 20%) and previous lesions (54% vs 4%). There was no difference in quality of diabetic control, or smoking habit. A simple classification of lesions was used. All types yielded mixed cultures of microorganisms (average 2.1 per swab); the flora obtained was affected by systemic antibiotics. Abnormal pressure was judged to have contributed to all lesions occurring in areas of callus. In addition definable trauma precipitated the event in up to 60% of all other types. Lesions in areas of callus were more likely to have healed by the end of the study period, but average time to healing was significantly longer than other lesions. Despite intensive outpatient support, 33 patients spent a total of 1188 days in hospital during the 974 day period, an average of 36 days per patient and 1.2 beds per day. Further research is urgently required to define optimal methods of prevention and treatment of diabetic foot ulcers.
