Pseudomonas aeruginosa is a leading cause of disease and death particularly in cystic fibrosis patients and also considered resistance to chemotherapeutic agents. Therefore, it is very difficult to remove the Pseudomonas aeruginosa from the hospital environment by using simple techniques. In the contemporary study, biofilm mediated mechanism of various antimicrobial responses were analyzed. For this purpose, different Pseudomonas aeruginosa clinical isolates were collected from Pakistan medical institute Islamabad (PIMS) hospital and were investigated for pellicle formation. Pseudomonas aeruginosa isolates were studied for different groups of antibiotics including imipenem, meropenem, ceftazidime, amikacin, tobramycin, gentamicin, piperacillin, cefoperazone, and cefotaxime. The goal was to check antimicrobial susceptibility of pseudomonas aeruginosa which shows resistant to tobramycin, imipenem, meropenem, amikacin, gentamicin, cefotaxime, piperacillin, ceftazidime, cefoperazone. Additionally, in this study, Pseudomonas aeruginosa strains were also investigated for pellicle formation. In conclusion, this research work wills highlights the useful mechanism of antibiotics resistance to Pseudomonas aeruginosa infections in clinical practice.

AbstractObjectiveThis study aimed to characterise antibiotics resistance ofEscherichia coliisolates from the formal meat sector (FMS) and informal meat sectors (INMS).MethodA total of 162 and 102E. coliisolates from the FMS, and INMS respectively were isolated by standard culture-based, and biochemical reactions. The isolates were further confirmed by polymerase chain reaction (PCR). The disc diffusion method was used to screen for antimicrobial susceptibility against 19 different antibiotics. The presence of class 1-2 integrons in eachE. coliisolates was assessed usingandregions specific primers.ResultAmong the 19 antimicrobials, resistance to tetracyclines, aminoglycosides, cephalosporins, and nitrofurans were found to be more frequent than carbapenems and phenicol with a noticeable increase in the number of multi-drug resistance ranging from three to ten antimicrobials. A total of 20 resistance determinants were assessed with their prevalence and distributions obtained as follows for FMS and INMS respectively; [aminoglycosides:aadA(40.6%; 31.9%),aacC2(21.4%; 31%),aphA1(20.8%; 15.1%),aphA2(37.7%; 18.9%) andstrA(6.5%; 9.4%)], [β-lactams:ampC(20%; 45%),blaTEM, (4.4%; 13.3), andblaZ(8.9%; 2.2%)], [Chloramphenicol:catI(1.7%; 1.7%), andcmIA1(1.7%; 1.7%)] and [tetracyclines:tetA(7.7%; 15.4%),tetB(11.5%; 24%), andtetM, (1.9%; 8.7%)], and [sulfonamides: sul1 (22.2%; 26.7%), sul2 (17.8%; 6.7%)].ConclusionMultiple antibiotic resistance (MAR) indexes ranged from 0.2 - 0.5. The results reveal a high prevalence of multidrug-resistantE. coliisolates and resistance determinants suggesting that consumers and handlers of such meat are at risk of contracting antibiotic resistantE. coli-related foodborne disease.

Antibiotics saves millions of lives in human and animal from bacterial infections, but resistance has been occurred and spreading borderless which pose health and economic problems. This study aimed to describe epidemiology (prevalence) of antibiotic resistant bacteria in human and animals and describing risk factors with strategic control efforts in Sub-Sahara Africa countries. Total 72 articles published from 2010 to 2017 were reviewed which reported on bacterium resistance to commonly-used antibiotics of different groups. Majority of isolated bacteria were highly resistant to b-lactams, Tetracycline and Sulphonamide, moderate resistant to Gentamycine and Aminoglycoside with low resistant to cephalosporin and quinolones for bacteria isolated from human while isolates from animal have high resistance to majority of antibiotic. High antibiotic resistant was associated by presence of weak/no regulation and irrational antibiotics use in Animal and Human health system, despite there is paucity of published data from central and southern African countries, lack of data sharing among laboratories and presence of few initiatives on control strategies of antimicrobial resistance while most of them are faced by resource limitations (skilled personnel, Equipments and Fund allocation). This study recommend that awareness on rational antibiotic use must be created, strong regulation to limit accessibility of antibiotics over the counter prescription, strengthening laboratory based diagnosis and surveillance, Infection control and prevention in hospitals with strong biosafety and biosecurity in animal farms are crucial. Adoption of “One Health Approach” is very important through multisectoral involvement, information sharing and networking.

Potential Activity

Antibiotic resistance is becoming significantly prominent and urgent in clinical practice with the increasing and wide application of antibacterial drugs. However, developing and synthesizing new antimicrobial drugs is costly and time-consuming. Recently, researchers shifted their sights to traditional Chinese medicine (TCM). Here, we summarized the inhibitory mechanism of TCM herbs and their active ingredients on bacteria, discussed the regulatory mechanism of TCM on antibiotic-resistant bacteria, and revealed preclinical results of TCM herbs and their active components against antibiotic-resistant bacteria in mouse models. Those data suggest that TCM herbs and their effective constituents exhibit potential blockage ability on antibiotic-resistant bacteria, providing novel therapeutic ideas for reversing antibiotic resistance.

The Impact

To assess the impact of antibiotic use in aquaculture in Nha Trang bay, we conducted this study with the aim of assessing antibiotic resistance of opportunistic pathogenic bacteria isolated from water and sediment around shrimp/fish cages in the Nha Trang bay. 109 strains of Vibrio, Salmonella-Shigella and Aeromonas groups were isolated in the surrounding environment of farming areas in Dam Bay and Hon Mieu. Antimicrobial resistance test of these 109 strains showed that in the water environment in Dam Bay, TET (96.6%) and NIT (92.5%) were the two antibiotics with the highest rates of resistant bacteria while no bacteria were resistant to RIF. All 5 types of antibiotics had a statistically insignificant percentage of antibiotic-resistant bacteria in water samples at Hon Mieu, ranging from 33.3% to 68.9%. Also in the water environment, the rate of antibiotic-resistant bacteria in Dam Bay was not influenced by the distance to the cages (42.5–66.6%). Meanwhile, in Hon Mieu, the highest rate of resistant bacteria was observed at the distance of 200 m (100%) away from cages and the lowest rate at the distance of 100 m (20%). In the sediment environment around the cages, both the Dam Bay and Hon Mieu farming areas showed the highest rates of antibiotic-resistant bacteria against TET, NIF and RIF had the lowest rate of resistant bacteria. Among the total of 109 strains tested for antibiotic resistance, 2 strains labeled TCBS_HM200 m and SS_HM200 m were found to be resistant to all 5 tested antibiotics. These two strains were respectively identified as Vibrio harveyi and Oceanimonas sp.

Candida is a yeast species recognized as the most frequent etiological agent of systemic and invasive thrush in humans. Invasions can affect all tissues, organs and systems of human in various stages of development. In the last 10 years Candida infections have increased 15 times. The purpose of our study was to determine the sensitivity of four antibiotics belonging to three different groups of antifungal agents against clinical and food-borne Candida strains. Our studies showed that of all tested strains, 7% was resistant to nystatin, 32% to fluconazole, 23% to voriconazole, and no strains grew in the presence of caspofungin. Despite the differences in biochemical profiles of clinical and food-borne isolates of Candida, a group of strains showing resistance to antibiotics include both types of isolates. At the same time circulating of antibiotic-resistant strains outside the hospital environment and the yeast infection via food is possible.

Carbapenem antibiotics resistance is a medical threat in antibacterial therapy as the pathogen resistant strains easily evolve a multi-drug resistance action to other incurable agents. The protective transport of current antibiotic molecules using nano-carriers initiates a huge approach in the antibacterial therapy, allowing the nanohybrids to defeat all these health threat pathogen agents. Chitosan is a linear cationic polysaccharide being often used in medical area as a biocompatible encapsulating agent in antibiotic delivery nanosystems. This work refers to encapsulation of imipenem into biodegradable chitosan nanoparticles in order to destroy antibiotic-resistant bacteria and limit the microbial adhesion and multiplication. Nanoparticles were prepared by ion gelation method using tripolyphosphate as cross linking agent. The obtained hybrid nanocapsules were then characterized and evaluated as a potential nano-device to beat antimicrobial resistance.

This study aimed to investigate the bacterial contamination of flake and cube ice being used dailyin the community. Thirty-one ice samples were collected from different areas in the city of Can Tho city, Vietnam. The enumeration of total aerobic mesophilic counts, the presence of coliforms and Escherichia coli (E. coli) and determination of antibiotics resistance of E. coli isolates were examined. The results indicated that total aerobic mesophilic counts ranged from 2.5 to 6.2 log CFU/mL and significant differences of total aerobic mesophilic counts were found between flake ice and cube ice (p < 0.05). Coliforms and E. coli were present on the ice samples of 93.55% and 58.06%, respectively. A total of 39 E. coli isolates were tested their resistance to 15 different antibiotics. The E. coli isolates of 74.36% were multi-resistance from three to thirteen antibiotics. The high prevalance was resistant to Ampicillin (79.49%), Cefotaxime (69.23%), Ceftazidime (46.15%), Tetracycline (56.41%), Sulfamethoxazole/Trimethoprime (46.15%), Colistin (20.51%), etc. As E. coli is an hygiene indicator and a candidate vehicle for the transfer of antibiotic resistance gene, it is highly recommended using clean and probable water in ice making as well as preventing the spread of antibiotic resistant bacteria.

The constant increase of antibiotic-resistant strains of bacteria is caused by extensive uses of antibiotics in medicine and animal breeding. It was suggested that the gut microbiota serves as a reservoir for antibiotics resistance genes that can be carried from symbiotic bacteria to pathogenic ones, in particular, as a result of transduction. In the current study, we have searched for antibiotics resistance genes that are located inside prophages in human gut microbiota using PHASTER prophage predicting tool and CARD antibiotics resistance database. After analysing metagenomic assemblies of eight samples of antibiotic treated patients, lsaE, mdfA and cpxR/cpxA genes were identified inside prophages. The abovementioned genes confer resistance to antimicrobial peptides, pleuromutilin, lincomycins, streptogramins and multidrug resistance. Three (0.46%) of 659 putative prophages predicted in metagenomic assemblies contained antibiotics resistance genes in their sequences.
