KSA-1, a naturally occurring Ambler class A extended spectrum β-lactamase from the enterobacterial species Kosakonia sacchari

Journal of Global Antimicrobial Resistance
Background: Several bacterial species belonging to the Gammaproteobacteria possess intrinsic class A β-lactamase genes that may represent a source of further dissemination and acquisition to other Gram-negative species.

High prevalence ofbla_CTX-Mextended-spectrum β-lactamase genes inEscherichia coliisolates from pets and emergence of CTX-M-64 in China [PDF]

Clinical Microbiology and Infection, 2009
As a cause of community-acquired infections, extended-spectrum β-lactamase (ESBL)-producing Escherichia coli constitute an emerging public-health concern. Few data on the molecular epidemiology of ESBL-producing E. coli isolates from pets are available in China.

Filtration‐Based SERS With In Situ Gold Growth in Bacterial Microenvironment for Rapid Detection of Low‐Level Bacteria

Small Methods, EarlyView.
A filtration‐assisted SERS platform integrating in situ gold growth within the bacterial microenvironment enables rapid and highly sensitive detection of low‐level bacteria in complex biological matrices. By overcoming hotspot–bacteria mismatch, the platform simultaneously achieves selective bacterial identification and rapid antimicrobial ...

The frequency of Klebsiella pneumonia encoding genes for CTX-M, TEM-1 and SHV-1 extended-spectrum beta lactamases enzymes isolated from urinary tract infection

Annals of Clinical Microbiology and Antimicrobials, 2018
Background The extended- spectrum β-lactamase producing bacteria are widely spread worldwide. The productions of these enzymes cause bacterial resistance to a wide range of antibiotics.

CTX-M and SHV-12 β-lactamases are the most common extended-spectrum enzymes in clinical isolates ofEscherichia coliandKlebsiella pneumoniaecollected from 3 university hospitals within Korea [PDF]

FEMS Microbiology Letters, 2005
Among the 443 clinical isolates of Escherichia coli and Klebsiella spp. collected between June and November 2003 from 3 university hospitals in Korea, 62 isolates were confirmed as extended-spectrum beta-lactamase (ESBL)- or plasmid-mediated AmpC beta-lactamase-producers by double disk synergy test, PCR and sequencing for beta-lactamase genes. The most

Isolation of carbapenem‐resistant Pseudomonas aeruginosa and other Gram‐negative ESKAPE organisms from samples of raw‐meat diets for dogs in the UK

Veterinary Record, EarlyView.
Abstract Background Gram‐negative ESKAPE organisms are an emerging threat in veterinary medicine that also have zoonotic potential. However, little is known about the prevalence and risks of these organisms in pet food. We present the incidental finding of gram‐negative ESKAPE organisms within samples of raw meat diets for dogs in the United Kingdom ...

High Prevalence of Extended-Spectrum β-Lactamase, Plasmid-Mediated AmpC and Carbapenemase genes in Food for Pets [PDF]

, 2014
We evaluated the pet food contained in thirty packages as potential origin of extended-spectrum cephalosporin-resistant Gram-negative organisms and β-lactamase genes (bla). Alive bacteria were not detected by selective culture.

Evolutionary and Epidemiological Characterization of Multidrug‐Resistant Escherichia coli Isolated From Pangolins in China

Integrative Zoology, EarlyView.
ABSTRACT Malayan pangolin populations have fallen to a critically endangered level, and illegal trafficking of wild pangolins is a global problem. Little is known about antimicrobial‐resistant bacteria (MDRB) harbored by pangolins, although pangolins are frequently consumed as food or used in traditional medicine. In this study, we report for the first
