Background: Multidrug resistant bacteria (MDR), such as Escherichia coli and Salmonella spp. are threat to the human health care system. In recent years, these MDR bacteria have been found increasingly inside and outside the hospital environment. Food animals (meat and poultry) are increasingly colonized with MDR bacteria, thus posing an additional concern. This study is intended to determine susceptibility and resistance pattern of pathogenic Gram negative bacteria isolated from rectal swabs of chicken against 16 antibiotics. Methods: A total of 216 cloacal swab samples (Gaza strip poultry farms) and 87 frozen and fresh meat samples (from slaughter houses and retails) from June 2017 to June 2018 were collected. Isolation and identification of organisms were achieved using standard bacteriological techniques. Antimicrobial susceptibility test was performed according to standard protocols. Results: 360 Enterobacteriaceae isolates, and 56 Gram-negative non fermenter were recovered. The predominant Enterobacteriaceae isolate was Citrobacter spp. (22.6%), followed by Enterobacter spp. (17.6%) and E. coli (16.5%). High rates of resistance against Ampicillin (85.4%) and Trimethoprim/ Sulfamethoxazole (80.1%) followed by Chloramphenicol (74%) were recorded. Six samples were positive for Salmonella spp. and Shigella spp. Of the tested Enterobacteriacae isolates, 94.7% were multidrug resistant (MDR), and 31.4% of  None fermenting bacilli (NFB) were MDR. Carbapenem resistance was found to be high among isolates; 51.9% for imipenem and 1.8% for meropenem. Conclusion: Isolated bacteria in the study area were MDR and this suggests that chickens may be important reservoir of antimicrobial resistant organisms which is a major public health concern.

ABSTRACTReports of outbreaks concerning carbapenemase-producing Gram-negative bacteria in which the main source of transmission is the hospital environment are increasing. This study describes the results of environmental sampling in a protracted polyspecies metallo-beta-lactamase GIM-1 outbreak driven by plasmids and bacterial clones ofEnterobacter cloacaeandPseudomonas aeruginosain a tertiary care center. Environmental sampling targeting wet locations (especially sinks) was carried out on a surgical intensive care unit and on a medical ward on several occasions in 2012 and 2013. We were able to demonstrate 43blaGIM-1-carrying bacteria (mainly nonfermenters but alsoEnterobacteriaceae) that were either related or unrelated to clinical strains in 30 sinks and one hair washbasin. GIM-1 was found in 12 different species, some of which are described here as carriers of GIM-1. Forty out of 43 bacteria displayed resistance to carbapenems and, in addition, to various non-beta-lactam antibiotics. Colistin resistance was observed in twoE. cloacaeisolates with MICs above 256 mg/liter. TheblaGIM-1gene was harbored in 12 different class 1 integrons, some without the typical 3′ end. TheblaGIM-1gene was localized on plasmids in five isolates.In vitroplasmid transfer by conjugation was successful in one isolate. The environment, with putatively multispecies biofilms, seems to be an important biological niche for multidrug-resistant bacteria and resistance genes. Biofilms may serve as a “melting pot” for horizontal gene transfer, for dissemination into new species, and as a reservoir to propagate future hospital outbreaks.IMPORTANCEIn Gram-negative bacteria, resistance to the clinically relevant broad-spectrum carbapenem antibiotics is a major public health concern. Major reservoirs for these resistant organisms are not only the gastrointestinal tracts of animals and humans but also the (hospital) environment. Due to the difficulty in eradicating biofilm formation in the latter, a sustained dissemination of multidrug-resistant bacteria from the environment can occur. In addition, horizontal transfer of resistance genes on mobile genetic elements within biofilms adds to the total “resistance gene pool” in the environment. To gain insight into the transmission pathways of a rare and locally restricted carbapenemases resistance gene (blaGIM-1), we analyzed the genetic background of theblaGIM-1gene in environmental bacteria during a long-term polyspecies outbreak in a German hospital.

Abstract Background: Surgical site infections are related to high morbidity, mortality and healthcare costs. As the emergence of multidrug-resistant bacterial pathogens in hospitals is becoming a worldwide challenge for surgeons who treat healthcare-associated infections, we wished to identify the causative agents involved in surgical site infections and their susceptibility pattern in six public hospitals in Benin. Methods: Using standard microbiological procedures, we processed pus specimens collected from obstetrics and gastrointestinal surgery wards. Mass spectrometry (MALDI-TOF) was used for confirmation. The antibiotic susceptibility test firstly used the Kirby-Bauer disc diffusion method. The secondary test by microdilution used the Beckton Dickinson Phoenix automated system (Becton Dickinson Diagnostic, USA). Results: We included 304 patients (mean age 32 ± 11 years), whose median length of stay was 9 days. A total of 259 wound swabs (85.2%) had positive aerobic bacterial growth. In obstetrics S. aureus (28.5%, n=42) was the most common isolate. In contrast, Gram-negative bacteria (GNB) were predominant in gastrointestinal surgery. The most dominant being E.coli (38.4%, n=31). Overall, 90.8% (n=208) of aerobic bacteria were multidrug resistant. Two-third of S. aureus (65.3%, n= 32) were methicillin-resistant Staphylococcus aureus (MRSA), three of which carried both MRSA and induced clindamycin resistance (ICR). GNB showed high resistance to ceftazidime, ceftriaxone and cefepime. Extended-spectrum beta-lactamases were presented by 69.4% of E.coli (n=43/62) and 83.3% of K. pneumoniae (n=25/30). Overall, twelve Gram negative bacteria (5.24%) isolates showed resistance to at least one carbapenem. No isolates showed a wild-type susceptible phenotype.Conclusion: This study shows the alarming prevalence of multidrug resistant organisms from surgical site infections in Benin hospitals. To reduce the spread of these multidrug-resistant bacteria, periodic surveillance of surgical site infections and strict adherence to good hand-hygiene practice are essential.

Aim: Prevalence of multidrug resistant bacteria on apparently health animals has turned antibiotic resistance to multifaceted process and threatens global food security and public health. The aim of the present study was to investigate the resistance profile of isolates from apparently healthy cattle in Maiduguri, Nigeria. Methodology: A total of 120 nasal swab samples were collected from cattle. Colony identification was according to the guidelines of Bergey’s Manual of Determinative Bacteriology. The susceptibility pattern of the isolates was conducted on the identified isolates according to the Modified Kirby-Baur disc diffusion method on Muller-Hilton agar and interpreted according to the procedures of Clinical Laboratory Standards Institute (CLSI, 2018) guidelines. Multiple Antibiotic Resistance Index (MARI) was calculated using the formula, MARI=a/b where “a” is the number of antibiotic resisted and “b” is the total number of antibiotic used in the study. Results: Of the total samples (120) from cattle 96 (80%) detected the following isolates; E. coli was the most commonly recovered isolates (33, 34.4%), followed by Klebsiella spp (28, 29.2%), Salmonella spp (21, 21.9%) and Pseudomonas aeruginosa (14, 14.5%). In this study, all the recovered isolates were found to be multidrug resistant gram negative bacteria, with highest resistance was shown by Salmonella spp. The high MARI observed in all the isolates in this study ranging from 0.7 to 0.9. MARI value of 0.2 > is suggests multiple antibiotic resistant bacteria and indicate presence of highly resistant bacteria. Conclusion: The study indicates highly resistant bacteria are carried by healthy food animals. Thus, there is need for continued monitoring of antibiotics use in animal husbandry to prevent further spread of resistance in Maiduguri, Nigeria.

AbstractHealthcare-associated infections (HAI) are an important public health threat with the multidrug-resistant (MDR) gram-negative bacteria (GNB) being of particular concern. Here we present the antimicrobial resistance profile of HAI-related GNB (HAIrB) isolated from patients (PT), healthcare workers (HCW) and hospital environment (HE) in a six-month screening program. From the 180 sampling points distributed in six hospital units, a total of 1,080 swabs were collected allowing the isolation of 390 HAIrB: 50.5% from HE, 42.6% from PT and 6.9% from HCW. Among the HAIrB, 32.6% were characterized as MDR and 38.7% as extended-spectrum cephalosporins resistant (ESC-R), showing no differences in the distribution between PT, HE and HCW. Carbapenem resistance (CARB-R) was detected for 17.7% of all HAIrB, being higher among Acinetobacter spp. isolates (36.5%), followed by Enterobacteriaceae (14.5%) and Pseudomonas spp. (11.8%). Except for the ICU, that revealed higher MDR, CARB-R and ESC-R rates, HAIrB-resistant profiles were similarly detected within the hospital units. Prevalence of blaKPC-like and blaCTX-M-1 β-lactamases-resistance genes was higher in K. pneumoniae and E. cloacae complex, while blaOXA-23-like and blaSPM-like were higher in A. baumannii and P. aeruginosa, respectively. This study reveals that the spreading of HAIrB within a hospital environment is higher than predicted, indicating that healthcare workers, hospital areas and equipment are key players on dissemination of MDR gram-negative bacteria and shows that an active surveillance program can provide precise understanding and direct actions towards control of HAI.

AbstractBackgroundEmergence of carbapenem resistance mechanisms among Gram-negative bacteria is a worrisome health problem. Here, we focused on to identify the presence of carbapenem-resistant bacteria among the samples collected from hospital environments in Tamil Nadu.MethodsA total of 30 hospital environmental samples were collected between August 2017 and January 2018 from hospitals located in Chennai and Vellore such as lift switches, stair rails, switchboards, nursing desks, used nursing gloves, door handles, wheelchairs, touch screens, chairs and from pillars inside the hospitals.Results and discussionA total of 22 carbapenem-resistant Gram-negative bacteria were isolated that included Escherichia coli, Klebsiella sp., Enterobacter sp., Salmonella sp., Pseudomonas aeruginosa and Acinetobacter sp. Interestingly, blaGIM-1 was detected in Acinetobacter variabilis strain isolated in samples collected from hospitals. Unlike other studies, the identified GIM-1 was not plasmid encoded, and this is the first report for the presence of GIM-1 (German imipenemase) in India.ConclusionExtensive surveillance programs are necessary to trace the uncontrolled spread of carbapenem-resistance genes in order to reduce the rapid spread of resistance.

Gram-Negative Bacteria (GNB) have been widely reported to cause worldwide infections and life-threatening. The high prevalence of drug-resistant GNB causes the treatment of GNB to become difficult. This case report describes a stepwise laboratory approach and interpretation for Gram-negative bacteria infection in sepsis patients. An 84-year-old female patient with a history of congestive heart failure, after three weeks of hospitalization, GNB was proven as the cause of sepsis. Laboratory approach for inflammation (C-reactive protein, procalcitonin) was made and confirmed with a positive culture of several specimens (sputum, urine, and blood). The identification of bacterial-culture revealed as Carbapenem-resistance Klebsiella pneumoniae and Extended-spectrum Beta-lactamases Escherichia coli. This case highlights GNB as a potential agent to worsen the infection (sepsis) and also a useful approach for the detection of multidrug-resistant bacteria, particularly in secondary hospital settings. The application and interpretation of integrated clinical and laboratory criteria may bring out better and effective patient management.

Abstract PURPOSE: Detection of carbapenemases among Gram-negative bacteria (GNB) is important for both clinicians and infection control practitioners. The Clinical and Laboratory Standards Institute recommends Carba NP (CNP) as confirmatory test for carbapenemase production. The reagents required for CNP test are costly and hence the test cannot be performed on a routine basis. The present study evaluates modifications of CNP test for rapid detection of carbapenemases among GNB. MATERIALS AND METHODS: The GNB were screened for carbapenemase production using CNP, CarbAcineto NP (CANP), and modified CNP (mCNP) test. A multiplex polymerase chain reaction (PCR) was performed on all the carbapenem-resistant bacteria for carbapenemase genes. The results of three phenotypic tests were compared with PCR. RESULTS: A total of 765 gram negative bacteria were screened for carbapenem resistance. Carbapenem resistance was found in 144 GNB. The metallo-β-lactamases were most common carbapenemases followed by OXA-48-like enzymes. The CANP test was most sensitive (80.6%) for carbapenemases detection. The mCNP test was 62.1% sensitive for detection of carbapenemases. The mCNP, CNP, and CANP tests were equally sensitive (95%) for detection of NDM enzymes among Enterobacteriaceae. The mCNP test had poor sensitivity for detection of OXA-48-like enzymes. CONCLUSION: The mCNP test was rapid, cost-effective, and easily adoptable on routine basis. The early detection of carbapenemases using mCNP test will help in preventing the spread of multidrug-resistant organisms in the hospital settings.

The prevalence of multidrug-resistant Gram-negative bacteria is a public health concern. Bacteriophages and bacteriophage-derived lytic enzymes have been studied in response to the emergence of multidrug-resistant bacteria. The availability of tRNAs and endolysin toxicity during recombinant protein expression is circumvented by codon optimization and lower expression levels using inducible pET-type plasmids and controlled cultivation conditions, respectively. The use of polyhistidine tags facilitates endolysin purification and alters antimicrobial activity. Outer membrane permeabilizers, such as organic acids, act synergistically with endolysins, but some endolysins permeate the outer membrane of Gram-negative bacteria per se. However, the outer membrane permeation mechanisms of endolysins remain unclear. Other strategies, such as the co-administration of endolysins with polymyxins, silver nanoparticles, and liposomes confer additional outer membrane permeation. Engineered endolysins comprising domains for outer membrane permeation is also a strategy used to overcome the current challenges on the control of multidrug-resistant Gram-negative bacteria. Metagenomics is a new strategy for screening endolysins with interesting antimicrobial properties from uncultured phage genomes. Here, we review the current state of the art on the heterologous expression of endolysin, showing the potential of bacteriophage endolysins in controlling bacterial infections.
