Chemical (zinc oxide with added iron oxide) used in the form of a pink powder or lotion to treat Itching and mild skin irritations.  

One per cent peptone in skim milk with bromcresol purple indicator. A simple medium for the primary cultivation of anaerobes from canned foods, allowing partial identification by reaction changes, casein digestion, gas production and ‘stormy clot’ formation. For specific purposes various additions and modifications have been proposed.  

Agglutination of organisms of one species by antiserum prepared against a different species, resulting from the possession by both of a common antigenic component (‘group antigen’).  

Device for the separation of the phases of a diphasic salmonella culture, by passing through sloppy agar containing H phase 1 or phase II salmonella-agglutinating antiserum. Only motile salmonella in the alternative phase to the serum used reach the top levels of the agar surrounding the inoculation tube, organisms of like phase to the serum…

Species associated with Q fever, diagnosed by animal inoculation (guinea-pig, hamster, chick embryos); tissue or yolk-sac smears from these stained by Castaneda or Macchiavello’s stain. The blood from these animals may also be tested for complement-fixing antibodies to egg-adapted strains of C. burnettii.  

Genus which, with the true rickettsia, make up the tribe of the Rickettsieae. Coxiella differ from rickettsia in that they are filterable, and do not stimulate the production of Weil – Felix agglutinins. A genus of rickettsia like microorganisms that cause disease in animals and man. They are smaller than rickettsiae, are transmitted by air-borne…
