“…Phage-typing, antimicrobial resistance testing and incompatibility determination Strains were phage typed by the methods of Callow [12] and Anderson and Williams [13], and tested for antimicrobial drug resistance by the methods of Anderson and Threlfall [14]. Mobilization of non-conjugative plasmids was achieved by using the conjugative plasmids, X (42 MDa, IncF,1) and A (60 MDa IncI1).…”

SUMMARYPlasmids in five strains of Salmonella typhimurium resistant to ampicillin, chloramphenicol, gentamicin, neomycin/kanamycin, streptomycin, sulphonamides, tetracyclines and trimethoprim (ACGKSSuTTm), CGKSSuTTm, ACSSuT or CSSuT which had been isolated from poultry in the first 3 months of 1989 have been characterized and compared with plasmids in two strains of R-types ACGKSSuTTm and ASSuTTm isolated from two patients later in the year. With the exception of the human isolate of R-type ASSuTTm, all strains carried two non-conjugative plasmids, one coding for SSu and belonging to incompatibility group Q, and a second coding for multiple resistance and belonging to the Flme

“…Large outbreaks usually linked to asymptomatic carriers who have excreted Salmonella typhi for years, however, have been reported from developed countries [I]. Bacteriophage typing requiring the presence of the Vi antigen is the method of choice to demonstrate epidemiologic associations among strains of this species [2], but its use is limited to reference laboratories that have all 100+ necessary phage suspensions available. Also, depending on the geographic location, only a few phage types represent the majority of strains isolated [3,4].…”

“…The plate was incubated in a moist chamber for 18-24 h at 43 'C in duplicate. The combined positive lytic reactions were recorded and the extended scheme was set up according to the established method of recording degrees of lysis on phagetyping plates [16]. Strains showing a pattern that did not conform to any recognized phage types were considered atypical (AT).…”

“…The scheme [9] has not yet been evaluated in studies using isolates from other countries. In our present scheme we have adopted the internationally established procedure of recording degrees of lysis with the typing phages as recommended by Anderson and Williams [16] for enteric pathogens (Table 1) and report 46 different phage types identified from human and non-human sources in 17 different countries (Tables 3, 4, and 5).…”

SUMMARYThe extended phage-typing scheme described for Campylobacter jejuni and Campylobacter coli has established 46 different phage types using 19 typing phages. Altogether 754 campylobacter isolates, 672 C. jejuni and 82 C. coli, isolated from human and non-human sources received from 17 different countries were phagetyped. Overall, 80 6 % of the total isolates were typable. Among typable strains, 9 phage types (3, 5, 10, 11, 18, 19, 23, 26 and 44) represented 57-0 % of the strains, 21P3 % of the strains belonged to another 37 phage types and the remaining 2f3 % of isolates were designated atypical. The most common phage type 11 (140/754) was frequently observed among C. jejuni isolates from human (113/561) and nonhuman sources (18/ 111), whereas type 44 was frequent among C. coli isolates from human (22/59) and from non-human sources (8/23). A study of the animal hostassociations of common phage types showed that contaminated cattle and poultry appear to be the most common sources of human infection. The greatest variety of phage types was observed in Canada (24 phage types), followed by Portugal (17 types) and the UK (14 types), reflecting the larger sample sizes from these countries. Phage type 11 was encountered in 12 different countries and prevalence of other phage types varied from one country to another. The number of isolates typable with the scheme varied from 93-2 % (261/280) in Canada to 61 % (47/77) in Thailand. However, the number and diversity of phage types makes phage typing the method of ehoice in epidemiological studies of campylobacter infections.
