The Occurrence of Bacteria of the Arizona Group in Man

Abstract

The occurrence of bacteria of the Arizona group in man is summarized. Of 87 cultures isolated from man, only 8 were derived from asymptomatic persons whereas 23 were derived from blood and localized infections. Two serotypes, 7:1,2,6 and 10:1,2,5, accounted for more than 50% of the cultures of human origin. Comments are made on the behavior of the organisms in man and the lower animals.

Bacteriological and Serological Studies of Organisms of the Arizona Group Associated with a Food‐Borne Outbreak of Gastroenteritisa

“…first mass food infection in which a completely identified Al-izona type was recognized. Although Edwards has now studied Arizona strains from more than 159 outbreaks (Edwards et al, 1956a(Edwards et al, , b, 1959, the laboratory findings accumulated during investigation of this outbreak are somewhat unique.…”

Arizona hinshawii Osteomyelitis in Sickle Cell Anemia

“…6 The mechanism by which patients with sickle cell anemia develop os¬ teomyelitis due to Salmonella has not been fully explained. It is generally held that transient ischemia of the bowel as a result of sickling may pre¬ dispose to invasion of enteric orga¬ nisms with subsequent localization in other ischémie areas such as bone.…”

Antigenic Analysis and Biochemical Characters of Strains of Escherichia Coli, Commonly Associated With Human Diarrhoea, Isolated From Sporadic Cases of Gastro-Enteritis in Local Population of Domestic Animals

“…IMViC reactions, nitrate reduction, gelatin liquefaction, deamination of phenylalanine to phenyl pyruvic acid, organic acid utilization, and carbohydrate fermentation tests were done according to EDWARDS and EWING (27), catalase production according to CRUICKSHANK (28), hydrogen sulphide production according to CLARKE (29), urease activity according to CHRISTENSEN (30), decarboxylase test according to FALKOW (31), and growth in KCN medium according to EDWARDS and FIFE (32).…”
