The minimum laboratory information required to report a specimen as positive for C. diphtheriae is as follows: Most biotypes are catalase positive, urea negative, nitrate positive (except the biotype belfanti), pyrazinamidase negative, and cystinase positive. dup 145 /G91 put Other methods for detecting toxin have also been described; these are primarily phenotypic tests based on complex techniques, such as immunoblotting, other EIAs, Vero cell bioassays, passive hemagglutination, immunofluorescence, and the use of latex immunologic techniques, but they have not found widespread use [12, 29].

dup 221 /GDD put The toxigenicity of diphtheria bacilli is demonstrated by incorporating strains in agar overlay of cell culture monolayers. dup 162 /GA2 put More recently, 16S ribosomal ribonucleic acid (rRNA) probes have been designed for the identification of genus and species of corynebacteria. Within the United Kingdom, Finland, and the United States, microbiologists, infectious disease physicians, and physicians in communicable disease control have a strong network of disease-reporting systems, which include official disease reports, the WHO manual and other manuals, courses, and seminars. dup 81 /G51 put Oxford University Press is a department of the University of Oxford. NOTE. 0000001318 00000 n dup 153 /G99 put [14]. dup 232 /GE8 put In a comparative study of 220 isolates, the EIA showed 100% correlation with the Elek test [28]. Further characterization of the isolate by ribotyping demonstrated clearly that the pattern produced was indistinguishable from the “epidemic pattern” D1 currently circulating within Eastern Europe. dup 237 /GED put

dup 198 /GC6 put The patient was given diphtheria antitoxin and clarithromycin. They will also ferment glucose, maltose, and starch (var. gravis was isolated from the membrane within 24 h of receipt by the Reference Laboratory. dup 208 /GD0 put And, as an example of accessible laboratory screening, the PHLS and CDC Reference Laboratories provide a 24-h, 7-days-a-week service for the laboratory diagnosis of diphtheria.

It is an, Many eukaryotic cell lines (e.g., Africangreen monkey kidney, Chinese hamster ovary) are sensitive to diphtheria toxin, enabling, Corynebacterium diphtheria: Properties of the Bacteria, Pathogenesis and Immunity - Corynebacterium diphtheria, Clinical Syndromes - Corynebacterium diphtheria, Epidemiology of Corynebacterium diphtheria, Treatment of Corynebacterium diphtheria infections, Prevention and Control of Corynebacterium diphtheria infections, Properties of the Bacteria Bacillus anthracis.

Not affiliated Case Classification. The Elek test was first described in 1949 [11] and replaced the in vivo virulence test in guinea pigs, a test that was used by many countries at that time. Laboratory diagnostics within the Newly Independent States (NIS) of the former Union of Soviet Socialist Republics are based upon the work of several generations of microbiologists and are in accordance with the WHO recommendations.
