Abstract. Wibisono FJ, Sumiarto B, Untari T, Effendi MH, Permatasari DA, Witaningrum AM. 2020. Short Communication: Pattern of antibiotic resistance on extended-spectrum beta-lactamases genes producing Escherichia coli on laying hens in Blitar, Indonesia. Biodiversitas 21: 4631-4635. The aims of this study were to determine the susceptibility pattern of phenotypic antibiotics on extended-spectrum beta-lactamases (ESBL) genes and genotype profiles of ESBL producing Escherichia coli strains isolated from cloacal samples of laying hens in Blitar. A total of 165 cloacal swab samples were successfully isolated 145 E. coli strains during the study taken from 5 subdistricts in Blitar. All the strains were examined for antibiotic resistance patterns by disk diffusion method with double-disk synergy test (DDST), followed testing with VITEK® 2 methods, molecular identification of ESBL coding genes using PCR. The results of this study showed that the characterization of nucleotide analysis from PCR amplification of ESBL-producing E. coli bacteria isolated from laying hens in Blitar showed that eight isolates were the dominant of CTX gene, followed by the TEM encoding gene of two isolates, and the SHV coding gene as much as one isolate. The presence of more than 1 encoding genes in the E. coli bacterial isolate was seen in 1 isolate, where the isolate carried the CTX gene and the SHV gene as well. All ESBL producing E. coli isolates were resistant to amoxicillin, ampicillin, cefazolin, cefotaxime, and ceftriaxone, and these ESBL isolates were more than 70% resistant to gentamicin, aztreonam, and trimethoprim/sulfamethoxazole. These results indicated that poultry is a potential reservoir for ESBL-producing E. coli. The presence of ESBL-producing E. coli in poultry requires strengthening antibiotic policy. This is important because the regulation of antibiotic use in poultry is gaining momentum to increase animal productivity and food safety in Blitar, Indonesia.

The aim of the study was to determine the drug resistance profile and to assess the presence of genes responsible for the production of extended-spectrum beta-lactamases in Escherichia coli isolated from energy-processed hop sediment with the addition of bulking agents. Antibiotic resistance was determined by the disk diffusion method and the PCR technique to detect genes determining the extended-spectrum beta-lactamases (ESBLs) mechanism. A total of 100 strains of E. coli were collected. The highest resistance was found to aztreonam, tetracycline, ampicillin, ticarcillin, and ceftazidime. The bacteria collected were most often resistant to even 10 antibiotics at the same time and 15 MDR strains were found. The ESBL mechanism was determined in 14 isolates. Among the studied genes responsible for beta-lactamase production, blaTEM was the most common (64%). The study revealed that the analysed material was colonised by multi-drug-resistant strains of E. coli, which pose a threat to public health. The obtained results encourage further studies to monitor the spread of drug resistance in E. coli.

Introduction: Some strains of Escherichia coli and Klebsiella pneumoniae produce Extended Spectrum Beta-Lactamases (ESBL) may be responsible for various infections such as urinary infections. These Sick people are treated in the very serious cases by association antibiotics to class to betalactamins, aminosids and quinolons. But proliferation of multi-drug resistant strains involves decreasing therapeutic success. That’s why epidemiological study must be done in all laboratories of bacteriology. Purpose: The aim of the study was to research the resistance phenotypes of our E. coli and K. pneumoniae ESBL strains compared to others families of antibiotics. Material and methods: Thirty two (32) Extended Spectrum betalactamases E. coli and K. pneumoniae strains isolated from either hospitalized patients or sick people who came for consultation were studied. Susceptibility to antimicrobial agents was determined using an antibiotic disk (Bio-Rad) diffusion method on Mueller-Hinton agar (Bio-Rad). The results were interpreted according to the Standards of the French Antibiogram Committee (CA-SFM). Results: The study showed that most of these strains were multi-drug resistant. They were resistant to many beta-lactamines antibiotics. E. coli strains were also resistant at 70,34% to aminosids, at 96,72% to quinolons, at 58,3% to cotrimoxazol, at 26,1% to chloramphénicol and at 21,4% to colistin ; about K. pneumoniae, they were resistant at 72,6% to aminosids, at 88,95% to quinolons, at 86,7% to cotrimoxazol, at 44,4% to chloramphénicol and at 25% to colistin. But all these strains were sensitive at 100% to l’imipenem.

The aim of this study was to determine antibiotic resistance patterns and the prevalence of uropathogenes causing urinary tract infections (UTIs) in patients hospitalized in January–June 2020 in central Poland. Antimicrobial susceptibility testing was performed using the disk-diffusion method. Escherichia coli (52.2%), Klebsiella pneumoniae (13.7%), Enterococcus faecalis (9.3%), E. faecium (6.2%), and Proteus mirabilis (4,3%) were most commonly isolated from urine samples. E. coli was significantly more frequent in women (58.6%) (p = 0.0089) and in the age group 0–18, while K. pneumoniae was more frequent in men (24.4%) (p = 0.0119) and in individuals aged 40–60 and >60. Gram-negative species showed resistance to ampicillin. K. pneumoniae were resistant to amoxicillin plus clavulanic acid (75.0%), piperacillin plus tazobactam (76.2%), cefotaxime (76.2%), cefuroxime (81.0%), ciprofloxacin (81.0%), and trimethoprim plus sulphamethoxazole (81.0%). Carbapenems were effective against all E. coli and P. mirabilis. Some K. pneumoniae (13.6%) produced metallo-β-lactamases (MBLs). E. coli (22.6%), K. pneumoniae (81.8%), and all E. faecium were multidrug-resistant (MDR). Some E. coli (26.2%), K. pneumoniae (63.6%), and P. mirabilis (14.3%) isolates produced extended-spectrum beta-lactamases (ESBL). Vancomycin-resistant E. faecium was also found. This study showed that the possibilities of UTIs therapy using available antibiotics become limited due to the increasing number of antibiotic-resistant uropathogens.

Tract Infections

Globally, urinary tract infections are one of the most common infections in need of urgent clinical attention. The prevalence of extended spectrum beta-lactamases (ESBL)- producing Escherichia coli isolated from urine samples of some UTI patients and s of apparently healthy individuals in Minna, Nigeria, is investigated. Standard microbiological techniques were used to conduct this study. A total of 170 catch midstream urine samples submitted to the Medical Microbiology Laboratories of 4 different hospitals (and samples from healthy individuals) were randomly collected for 5 months and examined for microbial growths. Female patients (65.9%) submitted more urine samples for UTI test than their male counterpart (34.1%). The age ranges of 21 -30 (26.5%) and 31 - 40 (25.3%) had the highest percentages of infection rate while those within the ages 1- 10 (3.5%) and ≥ 71 (2.3%) were the least infected. This study observed a prevalence of 23.5% of E. coli in Minna metropolis and a significant number (30%) of healthy individuals (HI) was observed to harbor the E. coli in their urine. The isolates were highly susceptible to Gentamicin (65%), Ofloxacin (65%), Tetracycline (62.5%), Cotrimoxazole (62.5%), and Streptomycin (57.5%). Mildly susceptible to Pefloxacin (37.5%), Chloramphenicol (37.5%), and Ciprofloxacin (35%). There were significant resistance to most of the beta-lactames tested [Cefuroxime (80%), Amoxicillin (42.5%), Augmentin (40), Cefotaxime (20%) and Ceftaxidime (7.5%)]. Two of the isolates were resistant to all the 13 antibiotics tested; 70% (28) of the isolates had multiple antibiotics resistance index (MARI) ≥0.3. Multidrug resistance was expressed in 37.5% of the isolates tested. The study showed a vast resistant pool in the environment. Only 25% of the E. coli isolated from the urine samples produced beta-lactamases phenotypically, most of which expressed resistance to more than 5 of the antibiotics tested and had MARI of ≥ 0.5. Further evaluation showed that 25% (10/40) of the E. coli isolated from the UTI patients in Minna, Nigeria, were ESBL- producers and could harbor one or two of the genes. TEM gene was expressed in 70% (7) of the isolates that produced ESBL phenotypically, 60% 6) harbored CTXM gene, 20% (2) had the OXA gene while none of the bacteria harbored the SHV gene. The study established a 5.9% ESBL prevalence among the E. coli isolated from UTI in the environment studied. This study established that E. coli is one of the prevalent bacteri urea majorly isolated from UTI patients in Minna. The prevalent E. coli are multidrug resistant and could harbor more than one ESBL gene . keywords: Escherichia coli, Minna, UTI, ESBL, Multidrug resistance
