Electron microscopic evidence of flagella and pili on Legionella pneumophila.

Twenty-one strains of Legionella pneumophila, representing the six known serotypes of the organism, cultured on various bacteriological media and in the yolk sacs of fertile hens' eggs were examined by negative stain electron microscopy for flagella and pili. These appendages were usually observed after cultivation on media capable of inducing an early profuse growth of the organisms.

New methods for the isolation of Legionella pneumophila.

Some new methods for the isolation of Legionella pneumophila are described which have been successful in recovering this organism from 6/10 patients with clinical evidence of Legionnaires' disease. The increased sensitivity of these methods combined with speedier isolation of the organisms than has hitherto been possible will hopefully lead to eventual isolation of this organism as a routine procedure in diagnostic microbiology laboratories.

Minimum inhibitory concentrations of penicillin and minocycline for 300 isolates of N. gonorrhoeae.

The minimum inhibitory concentrations of penicillin and minocycline were measured on 300 consecutive isolates of N. gonorrhoeae from patients attending the Nottingham treatment centre. 210 (70 per cent.) of these were fully sensitive to penicillin (MIC less than 0-1 mug./ml) and 89 per cent. were fully sensitive to minocycline (MIC less than 0-5 mug./ml.). Of the nine strains resistant to penicillin (MIC less than or equal to 0-5 mug./ml.), eight were also of reduced sensitivity to minocycline.

Selectagerm: a new approach to clinical bacteriology.

A method of processing clinical specimens received at the laboratory on cotton wool swabs is described. The method uses a range of selective culture media to assist in the isolation of potential pathogens from mixed cultures. Because the culture media are distributed in 2 millilitre volumes in the small squares of divided plastic petri dishes it is economically possible to use the same series for every specimen. This facilitates the rapid processing of large numbers of swabs and allows the isolation of pathogens from sites where they might otherwise go unnoticed.
