[Severe hypophosphoremia in a toxic shock syndrome].

A case of toxic shock syndrome occurring during a menstrual period, and associated with severe hypophosphataemia, is reported. The patient was a 21-year old woman using tampons. On the fourth day, she developed encephalopathy with decreased consciousness and hyperventilation. Severe hypophosphataemia was noted. A phage-group-1 Staphylococcus aureus, producing TSST-1 and enterotoxin A, was isolated from vaginal, pharyngeal and skin sites. Pathogenesis and role of hypophosphataemia in toxic shock syndrome are emphasized.

[Public health impact of adsorption of enteroviruses on ocean and river sediments].

Fixation of enteroviruses in sands, ocean sediments, and river mud constitutes a very real public health risk. The authors review the physicochemical and biological mechanisms of virus attachment to particles. Rates of adherence frequently reach 90 to 100%, especially in montmorillonites and sands. Studies devoted to microorganism adherence are mentioned. Attachment of enteroviruses to particles in suspension, to bacteria and other microorganisms--all becoming vectors--is described. Also reviewed is the manner in which these pathogenic substances are disseminated in the environment, especially at beaches, recreational areas and shellfish breeding areas. Greater vigilance to the dangers is advocated on the part of public health authorities, those responsible for environmental salubrity and for shellfish grounds.

[Distribution of ubiquinones (coenzyme Q) in Gram negative bacillae].

The coenzyme Q system was examined on 55 strains of Gram negative aerobic or facultatively anaerobic rods. No bacteria contain Co-Q7 nor Co-Q10. Ubiquinone Q8 predominates in Flavobacterium and in Enterobacteriaceae; Q9 was the only homolog found in the Pseudomonas, and predominates in the Acinetobacter.

[Potentialization of antibiotics by lytic enzymes].

Few lytic enzymes, specially papaine and lysozyme, acting on the membrane and cell wall structures facilitate effects of bacitracine, streptomycine and other antibiotics. Streptomycino resistant strains became sensibles to this antibiotic after contact with papaine and lysozyme. The results of tests in physiological suspensions concern only the lytic activity of enzymes. The results on nutrient medium concern together lytic, and antibiotic activities.

Microbiological study of a hypersaline lake in French Somaliland.

In a study of a lake having a higher concentration of salts than the Dead Sea, all of the heterotrophic bacteria isolated were aerobes; no strictly anaerobic strains were found. Ninety percent of the strains were euryhalines and ten percent were strict halophiles. The extreme halophiles belonged to the species Halobacterium trapanicum and Halococcus morrhuae.
