Background: Early-onset neonatal sepsis (ENOS) is one of the most common causes of mortality in neonates. The bacteria causing ENOS are generally transferred from the mother to the infant before or during labor. Objectives: This study aimed to determine the prevalence rate of nasopharyngeal colonization with common bacterial agents causing ENOS and their relationship with blood culture outcomes in neonates. Methods: All neonates transferred to the neonatal intensive care unit were included in the study. Posterior pharynx secretions were swabbed and cultured in blood agar and MacConkey agar. Also, a blood specimen from each neonate was inoculated into a blood culture bottle. The grown bacteria were identified by biochemical standard tests. The antibiotic sensitivity test was performed by the disk diffusion method using Mueller-Hinton agar, and the results were evaluated according to the CLSI guidelines. Results: The pharyngeal specimens collected from 114 newborns were positive in 83 (72.8%) cases. Staphylococcus epidermidis was the most common bacterium in all weight groups. However, the isolates of Klebsiella, Escherichia coli, S. aureus, and Streptococcus agalactiae were also high. Thirteen newborns died. Neonates’ pharyngeal specimens were positive among 11 (84.6%) cases who died and 101 (71.2%) neonates who survived. Twelve neonates had positive blood cultures. Simultaneous positive blood and pharyngeal cultures were reported in eight (7%) cases, in which the bacterial isolates from blood and pharyngeal samples were similar in three cases (37.5%). Among pharyngeal isolates, E. coli was resistant to ampicillin in 100% and gentamicin, cefotaxime, and ceftazidime in 50% of the cases. Also, S. epidermidis and Acinetobacter isolates from blood samples were resistant to ampicillin in 100% of the cases. Conclusions: S. epidermidis accounted for 38.6% of bacteria cultured from pharyngeal swabs and 66.7% of bacteria cultured from blood samples, 37.5% of which were resistant to ampicillin and 100% were sensitive to vancomycin. One-hundred percent of E. coli cultures from neonatal pharynges were resistant to ampicillin and about 50% of them were resistant to gentamicin, cefotaxime, and ceftriaxone.

In the present study, antibiogram of Escherichia coli isolated from farmed Asian clam, Corbiculafluminea was characterised. Asian clam or locally known as ‘etak’ is processed to became smokedclam and consumed as snack by Kelantanese. However, there are many diarrhoea cases afterconsuming smoked clam. Furthermore, there are also insufficient information about the E.coli levelin Asian clam farm and effective antibiotic in controlling the bacteria in the litereature. Hence, thisstudy was carried out to provide information of antibiogram of E.coli to be reference in the future.Eosin Methylene Blue agar (EMB) was used to isolate E. coli. A total of 100 isolated bacteria weresubjected to antibiotic sensitivity test using disk diffusion method. A total of 18 types of antibioticsnamely novobiocin (30µg/disk), fosfomycin (50 µg/disk), tetracycline (30µg/disk), lincomycin(15µg/disk), flumequine (30µg/disk), sulphamethoxazole (25 µg/disk), amoxycillin (25 µg/disk),chloramphenicol (30 µg/disk), oleandomycin (15 µg/disk), spiramycin (100 µg/disk), ampicillin(10 µg/disk), oxytetracycline (30 µg/disk), doxycycline (30 µg/disk), nalidixic acid (30 µg/disk),florfenicol (30 µg/disk), erythromycin (15 µg/disk), kanamycin (30 µg/disk) and oxolinic acid (2µg/disk). The findings of the present study showed total plate count of E. coli was 6.45 x 103 colonyforming unit (CFU/100g) of sampled Asian clam. Hence, the clam is needed to be under cleansingtreatment before can consider safe for human consumption. Antibiotic results showed 51 % wasrecorded as antibiotic resistance case, 44 % antibiotic sensitive case and 5 % as antibioticintermediary sensitive case. None of the tested antibiotics was successfully inhibited the growth ofthe present bacterial isolates indicating more antibiotics are needed to be screen in the future studyto find out the most effective antibiotic in controlling isolated E. coli.

Background. Extended-spectrumβ-lactamases (ESβLs) and AmpCβ-lactamases causeβ-lactam resistance inEscherichia coli. Fecal colonization by ESβL- and/or AmpC-positiveE. coliis a source of nosocomial infections.Methods. In order to investigate inpatient fecal colonization by ESβLs and AmpC, antibiotic sensitivity tests were conducted and minimum inhibitory concentrations (MICs) were determined using the disk diffusion method andE-test, respectively. Characterization of ESβL and AmpC was performed usingE-test strips, and a set of PCRs and DNA sequence analyses were used to characterize the ESβL and AmpC genes.Results. The whole collection ofE. coliisolates (n=50) was sensitive to imipenem, tigecycline, colistin, and fosfomycin, while 26% of the isolates showed reduced susceptibility to ceftazidime (MIC ≥ 4 μg/mL). ESβL was phenotypically identified in 26% (13/50) of cases, while AmpC activity was detected in two ESβL-producingE. coliisolates. All ESβL-producingE. coliwere positive for the CTX-M gene, eleven isolates carriedblaCTX-M-15, and two isolates carriedblaCTX-M-14gene. Two CTX-M-positiveE. coliisolates carriedblaCMY-2.Conclusions. The alimentary tract is a significant reservoir for ESβL- and/or AmpC-producingE. coli, which may lead to nosocomial infection.

Background: Escherichia coli various strains can cause alarmingly serious infections. Countries like Pakistan harbour the class of bacteria with one of the highest rates of resistance, but very little has been done to explore their genetic pool. Objectives: This study was designed to find out the frequency of virulence genes of Uropathogenic E. coli and their association with antibiotic resistance along with the evolutionary adaptation of the selected gene through the phylogenetic tree. Methods: Isolates from 120 urinary tract infected patients were collected. Antibiotic sensitivity was detected by the disk diffusion method and DNA extraction was done by the boiling lysis method followed by PCR-based detection of virulence genes. The final results were analysed using the chi-square test. Results: The isolates were found to be least susceptible to nalidixic acid, followed by ampicillin, cotrimoxazole, cefotaxime, ciprofloxacin, aztreonam, amoxicillin, gentamycin, nitrofurantoin and imipenem. The iucC was the most common virulence gene among the resistant isolates. About 86% of the collected samples were found to be multi-drug resistant. Statistical analysis revealed a significant association between the iucC gene and resistance to ampicillin (P=0.03) and amoxicillin (P=0.04), and also between fimH and resistance to aztreonam (P=0.03). Conclusion: This study unravels the uncharted virulence genes of UPEC in our community for the very first time. We report a high frequency of the iucC and fimH virulence genes. This, along with their positive association with resistance to beta-lactam antibiotics in the studied community, indicates their important role in the development of complicated UTIs.

Research has been conducted to evaluate the effect of antibiotics and silver nanoparticles in combination with antibiotics on the change in antibiotic sensitivity to antibacterial drugs of E. coli ATCC 25922 reference strain and its isolate. Nanoparticles obtained by electron beam treatment of aqueous solution containing water-soluble stabilizing polymer and water-soluble silver salt were used in the experiment. During the treatment a beam of accelerated electrons obtained on the installation of a linear accelerator of the ILU-10 type passed through a solution with a working dose of 5–30 kGy ranging in size from 20 to 60 nm. Sensitivity of microorganisms of E. coli ATCC 25922 reference strain and its isolate obtained from cow endometritis to antibacterial substances and their combinations was determined from dilution with a minimum bacteriostatic concentration. The dilution in the amount of 0.2 ml was added to meat-and-peptone agar and the antibiotic sensitivity of microorganisms was determined by the disk diffusion method. Sensitivity to 24 types of antibacterial drugs was tested. Cultivation of E. coli ATCC 25922 with AgNPs in combination with one of the antibiotics (azitronite, amoxicillin, enroflox, ceftiofur, tylosin, cobactan, oxytetracycline) contributed to an increase in the number of drugs (from 14.3 to 57.1%), to which the microorganism was sensitive. Cultivation of the E. coli isolate with 5 (62.5%) of the studied antibiotics led to an increase in resistance from 1 (5.5%) to 3 (16.7%) antibacterial agents. AgNPs in combination with antibiotics azitronite, amoxicillin, enroflox, ceftiofur, tylosin, cobactan, gentamicin, oxytetracycline contributed to a decrease in the resistance of E. coli ATCC 25922 (from 15.4 to 46.1%) and E. coli field isolate (from 16.7 to 37.7%) to antibacterial drugs. The pronounced ability of AgNPs to increase antibiotic sensitivity was established. This was confirmed by the joint cultivation of antibiotics and AgNPs with E. coli ATCC 25922 and field isolate of E. coli, causing an increase in sensitivity and high sensitivity to antibacterial drugs, which was previously absent. The study confirmed the results of research on the ability of nanoparticles of metals of the transition group to affect the sensitivity of microorganisms to antibacterial agents and to restore it.

Enterovirulent Escherichia coli remain as an important etiological agent of goat diarrhoea in Bangladesh. The present study was designed with a view to isolate and identifies E. coli from field cases. For this purpose, a total of 135 faecal samples (85 from diarrhoeic and 50 from apparently healthy goat) were collected during the period from January 2012 to July 2012 from different areas in Rangpur District. It was found that the prevalence of E. coli was higher (18.82 %) in diarrhoeic goats while it was lower (14.00 %) in non diarrhoeic goats. Age wise distribution of E. coli isolates were 26.42% in day old to 1 year, 10.53% in 1-2 years and 11.36% in above 2 years age of goat respectively. All the isolates of E. coli revealed greenish black colony with metallic sheen in Eosine methylene blue agar, bright pink color smooth transparent colony in MacConkey agar and slight pinkish smooth colony in Salmonella-Shigella agar. Gram stain and hanging drop techniques were performed with the cultured bacteria. Biochemical properties of the isolates were studied, and antibiotic sensitivity test was done by agar disk diffusion method. In Gram stain, the organisms revealed Gram negative, small rod shaped, occurs singly or paired. Biochemically, all of the isolates showed fermentation of dextrose, sucrose and maltose with the production of acid and gas, negative result to Voges-Proskauer test, positive result to Methylred test and differential result to Indol test. All the isolates of E. coli were highly sensitive to ciprofloxacin and gentamicin while moderately sensitive to colistin, livofloxacin and azithromycin and less sensitive to ceftraexon and tetracyclin and resistant to amoxycillin, ampicillin, erythromycin, and neomycin. Therefore, ciprofloxacin and gentamicin may be the antibiotics of first choice, and colistin, livofloxacin and azithromycin may be the second choice among the test antibiotics for the treatment of illness caused by these bacteria.Asian J.

In developing countries, the occurrence of antibiotic resistance is increasing day by day and antibiotic resistant microorganisms are being found in almost every environmental setting. Plasmids are considered as the main vector in the procurement and propagation of antibiotic resistance in many microorganisms such as Escherichia coli ( E. coli). The goal of this study was to examine the antibiotic resistance and screening of plasmid in E. coli strains which were previously identified from human sewage samples. During this study antibiotic susceptibility of E. coli isolates were determined by Kirby-Bauer disk diffusion method against 5 antibiotics (ampicilin, ceftriaxone, amoxicillin, ciprofloxacin, azithromycin). Furthermore, plasmid extraction of each isolate was done according to the protocol of FavorPrepTMPlasmid Mini Kit and plasmid profiling was done by agarose gel electrophoresis. In antibiotic sensitivity test, all E. coli strains showed resistance to ampicilin, amoxicillin, and ceftriaxone. In the plasmid profiling, it was revealed that all the isolates of E. coli harbored plasmids. The plasmid sizes ranged from approximately 1.5 to 15 kb. The findings of this study prove the consequences of antibiotic resistance as well as relationship of plasmid with antibiotic resistance which necessitates proper surveillance on antibiotic usage in the developing countries.

ABSTRACT BACKGROUND: Enteroaggregative Escherichia coli (EAEC) is one of the main acute and chronic diarrhea causes both in children and adults, mainly in developing countries. OBJECTIVE: The aim of the present study is to characterize EAEC strains isolated from faecal samples and to identify genes potentially contributing to virulence, biofilm production and antimicrobial resistance in children admitted to a pediatric hospital in Porto Velho, Rondônia State. METHODS: The total of 1,625 E. coli specimens were isolated from 591 children in the age group 6 years or younger who were hospitalized in Cosme and Damião Children Hospital in Porto Velho, between February 2010 and February 2012, with acute gastroenteritis. Colonies suggestive of E. coli were subjected to polymerase chain reaction testing in order to identify the virulence factors. The in vitro adhesion assays using HEp-2 adherence were tests. Biofilm detection through spectrophotometry and antimicrobial susceptibility tests were conducted in the disk diffusion method. RESULTS: The mentioned study examined 591 stool samples from children with diarrhea. Diarrheogenic E. coli was found in 27.4% (162/591) of the children. EAEC was the diarreagenic E. coli most frequently associated with diarrhea 52.4% (85/162), which was followed by enteropathogenic E. coli 43.8% (71/162), enterotoxigenic E. coli 2.4% (4/162), and enterohemorrhagic E. coli 1.2% (2/162). The aggR gene was detected in 63.5% (54/85) of EAEC isolates; moreover, statistically significant correlation was observed among typical EAEC (aggR) and aatA (P<0.0001), irp2 (P=0.0357) and shf (P=0.0328). It was recorded that 69% (59/85) of the 85 analyzed EAEC strains were biofilm producers; 73% (43/59) of the biofilm producers carried the aggR gene versus 42.3% (11/26) of non-producers (P=0.0135). In addition, there was association between the aatA gene and biofilm production; 61% (36/59) of the samples presented producer strains, versus 19.2% (5/26) of non-producers (P<0.0004). Antibiotic sensitivity test evidenced that most EAEC were ampicillin 70.6% (60/85), sulfamethoxazole 60% (51/85), tetracycline 44.7% (38/85) and cefotaxime 22.4% (19/85) resistant. CONCLUSION: As far as it is known, the present study is pioneer in Northern Brazil to investigate EAEC virulence factors and to show the antimicrobial susceptibility of EAEC strains isolated from children with diarrhea.

Antimicrobial resistance is currently becoming a global threat to human health. We performed a retrospective study on patients who underwent emergency cerclage between January 2016 and December 2018 at the Dongsan Medical Center. Cervical culture was first performed before surgery to confirm that there was no infection and was repeated on days 1, 4, and 7 after surgery. A total of 85 pregnant women underwent emergency cerclage. Among them, six patients had vancomycin-resistant enterococci (VRE) colonization in the cervix after cerclage, and 23 patients developed extended-spectrum β-lactamase (ESBL)-producing bacterial colonization in the cervix. The average gestational age at delivery was lower in the VRE group. Neonatal death was also significantly higher in the VRE group. The rate of occurrence of early-onset sepsis was also higher in the VRE group, and both VRE and ESBL-producing bacterial colonization cases in which early-onset sepsis occurred resulted in neonatal death. The prognosis of cervical VRE colonization after cervical surgery was poor, whereas the prognosis of ESBL-producing bacterial colonization in the cervix did not differ significantly from that of the control group. However, careful neonatal treatment is required considering that early-onset sepsis is fatal to the newborn.
