Incubation at raised temperature or enrichment media, combined with secondary enrichment in Rappaport's medium, for the isolation of salmonellas from sewage.

Two FMDV strains which had been previously differentiated by complement-fixation were compared by guinea-pig protection test, kinetic neutralization and micro-neutralization tests. It was found that these tests, which have not been previously applied by the methods described, were all capable of FMDV STRAIN DIFFERENTIATION. Similar differences were found by all methods, which suggests that comparisons made by cross-CF, cross-neutr-alization or cross-protection involve measurement of the same antigen/antibody interactions.

Postmortem study of the prevalence of gallstones in Athens.

The prevalence of gallstones in Athens in 1973 was studied in an autopsy survey that covered 1,448 subjects of all ages and both sexes. Gallstones were found in 5.2% of all subjects and in 6.2% of subjects older than 40 years. The prevalence was higher in females and considerably higher in persons who died from cirrhosis of the liver or from ischaemic heart disease.

[Healthy meningococcal carriers in 1973 in Greece. Sensitivity of the isolated strains to minocycline, rifampicin and sulphadiazine (author's transl)].

The frequency of healthy carriers of meningococci in Greece in 1973 has been studied by examining 1105 nasopharyngeal swabs from 731 recruits, during the four recruitment periods of this year. The frequency of healthy carriers among inductees within 24 hours from the arrival in the Camp was 38.9%. After a stay of 35 to 40 days in the training Camp the frequency of healthy carriers rose to 66.4%. Among all the soldiers examined, 24.5% were carriers of meningococci of group B, 13.2% of non-typable strains, 8.1% of autoagglutinable strains, 4.1% of meningococci of group A, 3.7% of meningococci of group C and smaller percentages of strains of groups X, Y, Z and of cross-agglutinating strains. The prevalence of carriers of meningococci of groups A and C and of autoagglutinable strains was higher among recruits who have been in the Camp for 35 to 40 days. The prevalence of carriers of the other serogroups was about the same among the inductees and the other recruits. No significant differences were found in the frequency of carriers of each serogroup among soldiers on their arrival, who were permanent residents of urban or rural areas of various parts of the country. No significant seasonal variation was noted in the frequency of carriers of each serogroup. Frequent changes of the group of meningococci harboured were noted among 374 recruits examined upon their arrival, as well as after 35 to 40 days of residence in the training Camp. Among 534 strains of meningococci examined none was resistant to either minocycline or rifampicin. Among 226 strains isolated from inductees, 44.7% were resistant to 1 mug/ml of sulphadiazine, while among 235 strains isolated from recruits after they have been in the Camp for 35 to 40 days, 57.9% were resistant to that sulphonamide.

Prevalence of hepatitis B antigen and antibody in prostitutes.

We investigated the prevalence of hepatitis B antigen (HBAg) and antibody (HBAb) in 293 prostitutes and in 379 pregnant women of similar age and of low socioeconomic level, who served as controls. HBAg was found in 4.4% of prostitutes and 3.4% of controls. The prevalence of HBAb was significantly higher (P <0.001) in prostitutes (56.7%) than in controls (24.5%). The prevalence of HBAb was clearly age-dependent in both groups. Evidence of hepatitis B virus infection significantly increased with the number of years in prostitution. The evidence of increased infection rates among prostitutes and their distribution support the hypothesis that hepatitis B infection is sexually transmitted.
