salmonellosis in indonesia: phage type distribution of salmonella paratyphi a.the distribution of phage types among 221 human strains of salmonella paratyphi a in indonesia was studied. approximately 50% were phage type 5, a rare type elsewhere in the world. most other isolates were the cosmopolitan phage type 1. the ratio of phage type 1-5 was compared for two cities on java, jakarta and yogyakarta. the ratios were significantly different, phage type 5 predominating in jakarta. the ratio of phage types among 10 s. paratyphi a strains isolated from jakarta river water was ...1977407296
[results of phage typing of salmonella typhi and salmonella paratyphi-b in the years 1970-1973 (author's transl)].between 1.1.1970 and 31.12.1973 3639 strains were typed with the aid of phage typing. of these strains 1793 belonged to s. typhi and 1846 to s. parathyphi-b. 40 s. typhi phage types were found. 9 of these occurred in a frequency of more than 1% (relevant to foci). these were e1 (25.7%) (of this e1a 19.7%, e1b 5.9%), a (16.6%), f1 (7.5%), d1 (59%), c1 (5.4%) d2 (2.3%), 46 (2.1%), 28 (1.9%). among s. paratyphi-b 24 phage types resp. varieties were found, 14 of these occurred in a frequency of more ...1977403709
immunochemical relations of salmonella paratyphi c with the salmonellae of group b.agar-gel precipitations of proteins from s. paratyphi c, s. paratyphi b and s. typhimurium against homologous and heterologous antibacterial sera, prepared in rabbits, demonstrated a strong relatedness between these species belonging to different serogroups. the findings explain and substantiate previous experiments in which high cross-protections were obtained in groups of mice immunized with proteins from these species and subsequently infected with s. typhimurium or its "in vivo" related s. p ...1977339608
antimicrobial resistance and incidence of r factor among salmonella isolated from patients with enteric fever and other clinical conditions in madras, india (1975-1976)the incidence of transmissible drug resistance among salmonella isolated from patients with enteric fever and other clinical conditions is reported. all of the salmonella isolated were studied for antimicrobial resistance. of the 336 strains, five were multiply resistant to drugs including chloramphenicol, and four of these strains transmitted resistance to escherichia coli f-lac+. multiply drug resistant e. coli were isolated from 12 patients receiving chloramphenicol, and in seven cases the e. ...1977336802
genetics of sensitivity of salmonella species to colicin m and bacteriophages t5, t1, and es18.nearly all of 62 strains of salmonella paratyphi b were sensitive to colicin m and phage t5 but resistant to phages t1 and es18 and to colicin b. all tested s. typhimurium strains were resistant to colicin m and phage t5, and many were sensitive to phage es18. a rough s. typhimurium lt2 strain given the tona region of escherichia coli or s. paratyphi b became sensitive to colicin m and phage t5. we infer that the tona allele of s. paratyphi b, like that of e. coli, determines an outer membrane p ...1977324978
a study of enteropathogenic organisms isolated in the public health laboratory, lusaka.a total of 328 specimens of stools were examined in the public health laboratory during january and february 1973. enteropathogens were isolated from 117 of these specimens. besides these, 12 strains of salmonellae were isolated from blood and 8 from urine. an occasional salmonella was isolated from the pleural fluid (s. paratyphi a) pus from the knee (s. enteritidis) and from the c.s.f. of an infant (s. paratyphi c.). salmonella typhi and salmonella paratyphi a are the predominant salmonella sp ...1977328771
genetic basis of vi antigen expression in salmonella paratyphi c.analysis of hybrids formed in a cross between a salmonella paratyphi c hfr and an s. typhimurium recipient indicated that the structural genetic determinants of the s. paratyphi c vi antigen are located closely adjacent to the mel determinant, between this marker and pura. a similar location was indicated for the structural genetic determinants of the s. typhi vi antigen (the viab locus) by the results of a mating in which a hybrid s. typhimurium hfr bearing the s. typhi viab determinants was us ...197768953
