“…This bacterium is an important opportunistic pathogen associated with serious infections. Recently, in Brazil, Cayô et al 30 reported an outbreak of septic shock associated with this strain. S. marcescens has been isolated from frozen shrimp and fish and may be associated with fish deterioration 31 .…”

The present study aims to detect the production of extended-spectrum beta-lactamases (ESBL) by enterobacteria isolated from samples of fresh shrimp and fish obtained from the retail trade of the city of Sobral, Ceará State, Brazil. All bacterial isolates were submitted to identification and antimicrobial susceptibility testing using aminopenicillin, beta-lactamase inhibitors, carbapenem, 1st, 2nd, 3rd and 4th generation cephalosporins, and monobactam. Three types of beta-lactamases - ESBL, AmpC and KPC - were investigated. 103 strains were identified, and the most frequent species in shrimp and fish samples was Enterobacter cloacae (n = 54). All the strains were resistant to penicillin and more than 50% of the isolates were resistant to ampicillin and cephalothin. Resistance to three 3rd generation cephalosporins (cefotaxime, ceftriaxone and ceftazidime) and one fourth generation cephalosporin (cefepime) was detected in two isolates of E. cloacae from shrimp samples. Phenotypic detection of AmpC was confirmed in seven strains. The ESBL was detected in two strains of E. cloacae from shrimp samples. No strain showed KPC production. These data can be considered alarming, since food (shrimp and fish) may be carriers of enterobacteria resistant to drugs of clinical interest.

“…T he Serratia marcescens enzyme (SME) is an Ambler class A carbapenemase that was first identified in 1982 from two clinical S. marcescens strains in England (1) and has since been reported elsewhere in Europe (2,3), North America (4-6), and South America (7,8). Although the prevalence of SME-producing S. marcescens currently appears low, it is likely underestimated because none of the commercially available carbapenemase detection methods include bla SME (9).…”

The Serratia marcescens enzyme (SME) is a chromosomally encoded carbapenemase with no known optimal treatment. Various β-lactam/β-lactamase inhibitors and comparators were evaluated against 8 SME producers via broth microdilution. Four isolates were subsequently tested via time-kill analyses. All isolates were resistant to imipenem, imipenem-relebactam, and meropenem but susceptible to ceftazidime, ceftazidime-avibactam, and meropenem-vaborbactam. Ceftazidime, imipenem-relebactam, and meropenem-vaborbactam were bactericidal against 3, 0, and 4 isolates, respectively. Meropenem-vaborbactam may be a potential option for severe SME-producing infections.

“…This problem has already been emphasized in some countries, including Brazil. 6,7 Third, PMB resistance does occur without carbapenem resistance, 8 and this "silent resistance" is a concern because PMB is often used in clinical practice against those CRE. Fourth, although a small number of isolates was detected in this study, Enterobacter species are important in the acquisition of PMB resistance; they have been cited as a second epidemic agent emerging after the wave of a KPC-Kp.…”
