“…A similar low incidence was found at Glasgow Royal Infirmary (Black, 1970). Information from colleagues in various parts of the country and, informally, from the Medical Research Council's Committee on Hospital Infection indicated that this was generally true in the U.K. A similar low incidence was reported to us from hospitals as far apart as Canada (personal communications from Dr F. A. Holden, University Hospital, Saskatoon, Mrs C. A. Johnston, Royal Jubilee Hospital, Victoria, and Dr D. H. Starkey, Queen Mary Veterans Hospital, Montreal) and Hong Kong (Dr C .…”

S U M M A R YR factors transmissible to Escherichia coli from naturally occurring strains of Serratia marcescens belonged either to compatibility groups ( S and L) not represented amongst plasmids reported in other genera or to groups (C, FII, P and M) notable for their wide host range. We have collected strains of S. marcescens, most, but not all, clinical isolates, from widely separate geographical areas; each strain was tested for antibiotic resistance and for R factors transmissible to E. coli K 1 2 . The R factors were classified by compatibility in K 1 2 (Datta, 1974). Our purpose was to find out how much of the antibiotic resistance observed in M E T H O D SSerratia marcescens. The sources of the 236 strains of S. marcescens studied are shown in Antibiotic resistance patterns were scored using a disc method (Hedges, 1974). Transfer of resistance to Escherichia coli ~1 2 .A rifampicin-resistant mutant of E. coli ~1 2 , 562-2 (Hedges, 1974) was used as recipient in tests for transfer. Methods were as described by Coetzee et al. (1972).

“…Fifty-eight strains of S. marcescens and 2 strains of S. liquefaciens were isolated from 59 patients over a period of 14 months. The isolation rate was low compared with hospitals in the U.S.A. but was approximately twice that reported by Black & Hodgson (1971), who conducted a similar survey in Scotland, whether isolations per month or per specimen were compared. This difference may be fortuitous, but the possibility that there has been a recent, true increase in the occurrence of Serratia in British hospitals cannot be excluded.…”

“…1977. During a 4-month period Black & Hodgson (1971) isolated 10 strains of S. marcescens from clinical specimens examined in a routine bacteriology laboratory, Ball, McGhie & Geddes (1977) have reported 14 cases of infection with S. marcescens over an 8-month period and Tabaqchali, Chambers & Brooks (1977) in a preliminary report demonstrated a higher incidence. In contrast, Hedges, Rodrigues-Lemoine & Datta (1975) recorded only one or two Serratia isolations per annum in a laboratory handling about 60000 clinical specimens each year.…”

SUMMARYA 14-month survey was undertaken in a diagnostic bacteriology laboratory to determine the incidence of Serratia spp. in routine clinical specimens. Gramnegative organisms with enterobacteria-like colonies were tested by a simple screening procedure. Fifty-eight strains of S. marcescens and two strains of S. liquefaciens were isolated from 59 patients. The strains were usually nonpigmented and exhibited multiple antibiotic resistance. Serotyping and determination of bacteriocine sensitivity patterns revealed that the majority of infections were sporadic, although episodes of cross-infection did occur.S. marcescens was considered to contribute significantly to morbidity and mortality in 53 % of patients and appears to be of increasing importance in hospital-acquired infections.

A study of serological, bacteriocine and phage typing of Serratia marcescens was made. Specific 0-antisera of adequate titre were relatively simple to prepare but H-antisera exhibited many heterologous agglutination reactions amongst the type strains. Most of these cross-reactions were not reproduced when immobilization tests with H-sera were performed. Direct haemagglutination tests were used to establish the presence of fimbriae amongst the H-type strains and the results of agglutination tests with non-fimbriate variants of strains indicated that fimbrial antibody in high titre was present in some sera.Replicate typing of 100 pairs of cultures by the phage-typing method indicated that small variations in pattern were common and that larger variations occurred occasionally. Therefore differences in pattern of less than two strong reactions should not be taken as evidence that strains can be distinguished.Cultures of S. marcescens, 273 in total, from six outbreaks of infection in British and European hospitals were typed by 0-serology, H agglutination and immobilization tests, phage typing and bacteriocine susceptibility by a cross-streaking method. The typability of strains by each method was high but the results suggested that no single method was sufficiently discriminating to be used alone for typing. Comparison of the H-type and typing patterns of members of the same 0 serogroup from incidents of infection showed that reliable results were obtained by H-typing or by phage and bacteriocine typing after the application of the appropriate 'difference' rule.The greatest discrimination between strains of the same 0-group was obtained by the use of H-typing or phage typing. UNTRODUCTIONMany different methods have been used for the epidemiological type identification of strains of Serratia marcescens. They include serological typing of 0 and
