Description
Tazobactam acid is a pharmaceutical drug that inhibits the action of bacterial β-lactamases, especially those belonging to the SHV-1 and TEM groups. It is commonly used as the sodium salt. It is derived from the penicillin nucleus and is a penicillinic acid sulfone. It is used with β-lactam antibiotics to enhance their effect. It has antibacterial activity.

1.The erratic antibiotic susceptibility patterns of bacterial pathogens causing urinary tract infections.
Ahmed I1, Sajed M1, Sultan A1, Murtaza I1, Yousaf S2, Maqsood B3, Vanhara P4, Anees M5. EXCLI J. 2015 Aug 4;14:916-25. doi: 10.17179/excli2015-207. eCollection 2015.
Increasing trend of antibiotic resistance and expression of Extended Spectrum Beta Lactamases (ESBLs) are serious threats for public health as they render the treatment ineffective. Present study was designed to elucidate the antibiotic-susceptibility patterns of ESBL and non-ESBL producing E. coli and K. pneumoniae causing urinary tract infections so that the ineffective antibiotics could be removed from the line of treatment. The bacterial isolates obtained from the urine of patients visiting a tertiary health care facility were cultured for strain identification using API20E. Antimicrobial susceptibility and ESBL detection were done by Kirby-bauer diffusion technique. Almost 53.4 % isolates of E. coli and 24.5 % isolates of K. pneumoniae were found to be ESBL producers. The ESBL producing bacteria were found to be more resistant towards various antibiotics. The most effective drugs against E. coli ESBL isolates were imipenem (99.54 %), ampicillin-sulbactam (97.
2.A resurgence of β-lactamase inhibitor combinations effective against multidrug-resistant Gram-negative pathogens.
Bush K1. Int J Antimicrob Agents. 2015 Nov;46(5):483-93. doi: 10.1016/j.ijantimicag.2015.08.011. Epub 2015 Sep 25.
β-Lactamase inhibitors (BLIs) have played an important role in combatting β-lactam resistance in Gram-negative bacteria, but their effectiveness has diminished with the evolution of diverse and deleterious varieties of β-lactamases. In this review, a new generation of BLIs and inhibitor combinations is presented, describing epidemiological information, pharmacodynamic studies, resistance identification and current clinical status. Novel serine BLIs of major interest include the non-β-lactams of the diazabicyclo[3.2.1]octanone (DBO) series. The DBOs avibactam, relebactam and RG6080 inhibit most class A and class C β-lactamases, with selected inhibition of class D enzymes by avibactam. The novel boronic acid inhibitor RPX7009 has a similar inhibitory profile. All of these inhibitors are being developed in combinations that are targeting primarily carbapenemase-producing Gram-negative pathogens. Two BLI combinations (ceftolozane/tazobactam and ceftazidime/avibactam) were recently approved by the US Food and Drug Administration (FDA) under the designation of a Qualified Infectious Disease Product (QIDP).
3.[Sensitivity surveillance of Streptococcus pneumoniae isolates for several antibacterial agents in Gifu and Aichi prefectures (2011-2012)].

Jpn J Antibiot. 2015 Aug;68(4):225-42.
We investigated the susceptibility to antibacterial agents, genotype of penicillin-binding protein (PBP) genes and macrolide resistant genes, and the serotypes against 270 strains of Streptococcus pneumoniae isolated from medical facilities in Gifu and Aichi prefectures between October 2011 and April 2012. These results were compared with those against S. pneumoniae isolated in 2008-2009 and 2010-2011. The number of gPSSP with 3 normal PBP genes, gPISP with 1 or 2 normal PBP genes and gPRSP with 3 abnormal genes isolated in 2011-2012 was 15 (5.6%), 162 (60.0%) and 93 (34.4%) strains, respectively. Compared with those isolated in 2008-2009 and 2010-2011, the numbers of gPRSP were decreasing. On the other hand, the isolates with no macrolide-resistant gene, only mefA, only ermB, and both mefA and ermB were 16 (5.9%), 75 (27.8%), 153 (56.7%) and 26 (9.6%). Compared with those isolated in 2008-2009 and 2010-2011, the numbers of isolates with ermB, which was usually associated with high-level resistance, were increasing.
4.Characterization of VCC-1, a Novel Ambler Class A Carbapenemase from Vibrio cholerae Isolated from Imported Retail Shrimp Sold in Canada.
Mangat CS1, Boyd D1, Janecko N2, Martz SL3, Desruisseau A3, Carpenter M1, Reid-Smith RJ2, Mulvey MR4. Antimicrob Agents Chemother. 2016 Jan 11;60(3):1819-25. doi: 10.1128/AAC.02812-15.
One of the core goals of the Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS) is to monitor major meat commodities for antimicrobial resistance. Targeted studies with methodologies based on core surveillance protocols are used to examine other foods, e.g., seafood, for antimicrobial resistance to detect resistances of concern to public health. Here we report the discovery of a novel Ambler class A carbapenemase that was identified in a nontoxigenic strain of Vibrio cholerae (N14-02106) isolated from shrimp that was sold for human consumption in Canada. V. cholerae N14-02106 was resistant to penicillins, carbapenems, and monobactam antibiotics; however, PCR did not detect common β-lactamases. Bioinformatic analysis of the whole-genome sequence of V. cholerae N14-02106 revealed on the large chromosome a novel carbapenemase (referred to here as VCC-1, for Vibrio cholerae carbapenemase 1) with sequence similarity to class A enzymes.
