Abstract
Biofilms are complex communities of microorganisms that are enclosed in a matrix that shows increased resistance to antimicrobial and immunological encounters. Mostly, the traditional methods to control biofilm are exhausted; therefore, the aim is to evaluate the potential of essential oil (EO) from Tagetes minuta to encounter biofilm and other related virulence factors. The EO of T. minuta was extracted through steam-distillation, analyzed on gas chromatography-mass spectrometry, and the biofilm inhibition assays were performed with various concentrations of EO. Mainly the EO from T. minuta contains cis-β-ocimene (29.1%), trans-tagetenone (23.1%), and cis-tagetenone (17.7%). The virulence factors were monitored while applying different concentrations of EO and it was recorded that the EO from T. minuta significantly inhibited the virulence factors linked with quorum sensing (QS), such as pyocyanin production, protease production, and swarming motility. Biofilm formation is one of the most important virulence factors associated with the QS pathway and was inhibited up to 79% in the presence of EO. Antibacterial activity against the PAO1 of EO was not so promising particularly and it has high MIC (325 μg/mL) and MBC (5000 μg/mL). EO is quite efficient to inhibit biofilm in a very small concentration of 20 μg/mL, which confirms that the biofilm inhibition by EO is not by killing bacterial cells but by inhibiting the QS pathway. The study on PAO1 constructs carrying various QS reported genes confirmed that the EO interferes with the QS pathway that ultimately controls various virulence factors caused by PAO1.

Abstract
Joint defects associated with a variety of etiologies often extend deep into the subchondral bone leading to functional impairment and joint immobility, and it is a very challenging task to regenerate the bone-cartilage interface offering significant opportunities for biomaterial-based interventions to improve the quality of life of patients. Herein drug-/bioactive-loaded porous tissue scaffolds incorporating nano-hydroxyapatite (nHAp), chitosan (CS) and either hydroxypropyl methylcellulose (HPMC) or Bombyx mori silk fibroin (SF) are fabricated through freeze drying method as subchondral bone substitute. A combination of spectroscopy and microscopy (Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), and X-ray fluorescence (XRF) were used to analyze the structure of the porous biomaterials. The compressive mechanical properties of these scaffolds are biomimetic of cancellous bone tissues and capable of releasing drugs/bioactives (exemplified with triamcinolone acetonide, TA, or transforming growth factor-β1, TGF-β1, respectively) over a period of days. Mouse preosteoblast MC3T3-E1 cells were observed to adhere and proliferate on the tissue scaffolds as confirmed by the cell attachment, live-dead assay and alamarBlue™ assay. Interestingly, RT-qPCR analysis showed that the TA downregulated inflammatory biomarkers and upregulated the bone-specific biomarkers, suggesting such tissue scaffolds have long-term potential for clinical application.

Abstract
This study aimed to synthesize the silver nanoparticles (SNPs) and loaded chitosan nanoparticles (LCNPs) using Euphorbia prostata based on their anticandidal activity. Antioxidant capacity and the total phenolic and total flavonoid content of plant samples and synthesized nanoparticles (NPs) were also evaluated. SNPs and LCNPs were prepared, respectively using chemical reduction of silver salt solution and ionotropic gelation method. The anticandidal activity was assessed by broth micro-dilution method and the antioxidant activity was determined using free-radical scavenging assays. The synthesized NPs after the optimization process were found to be spherical with sizes ranging from 12 to 100 nm. Spectroscopic analysis of NPs showed the appearance of peaks in prescribed wavelength ranging between 402 and 493 nm. The synthesized NPs showed potent anticandidal activity compared to the free extract. The SNPs formulations NpEPM 7.5 and NpEPMR 7.5, showed significantly low MIC values ranging between 2 and 128 µg/mL. In the case of LCNPs, NpEPM (4:1) and NpEPME (4:1) also showed lower MIC values ranging from 32 to 256 µg/mL. The plant samples as well as NPs showed antioxidant potential. In addition, plant extracts and NPs possess the potent biological potential and can be further investigated through in vivo experiments.

Abstract
Implantation of biomaterials capable of the controlled release of antibacterials during articular cartilage repair may prevent postoperative infections. Herein, biomaterials are prepared with biomimetic architectures (nonwoven mats of fibers) via electrospinning that are composed of poly(ɛ-caprolactone), poly(lactic acid), and Bombyx mori silk fibroin (with varying ratios) and, optionally, an antibiotic drug (cefixime trihydrate). The composition, morphology, and mechanical properties of the nanofibrous mats are characterized using scanning electron microscope, Fourier transform infrared spectroscopy, and tensile testing. The nonwoven mats have nanoscale fibers (typical diameters of 324-725 nm) and are capable of controlling the release profiles of the drug, with antibacterial activity against Gram +ve and Gram -ve bacteria (two common strains of human pathogenic bacteria, Staphylococcus aureus and Escherichia coli) under in vitro static conditions. The drug loaded nanofiber mats display cytocompatibility comparable to pure poly(ɛ-caprolactone) nanofibers when cultured with National Institutes of Health (NIH) NIH-3T3 fibroblast cell line and have long-term potential for clinical applications in the field of pharmaceutical sciences.

Abstract
The descriptive cross-sectional study was planned to evaluate drug-related problems, including drug-drug interactions, dose error, use of nephrotoxic drugs and polypharmacy, with special emphasis on kidney disease patients. The study was conducted from January to June 2019 in the Nephrology Ward of Ayub Teaching Hospital, Abbottabad, Pakistan. Doses of medicine and drug-drug interactions were evaluated by comparing it with standard protocols in British National Formulary and Lexicomp. Prescriptions were also evaluated for polypharmacy and use of nephrotoxic drugs. Out of 131 patients, 72 (55%) were males. Drug-drug interactions were found in 69 (52.7%) patients among whom the highest percentage was of moderate drug-drug interaction 63 (48.1%), followed by major 39 (29.8%) and minor 29 (22%) drug-drug interactions. Incidence of polypharmacy 68 (51.9%) and use of nephrotoxic drug 101 (77%) was high, while dose error was low 14 (10.7%). All drug-related problems were present with a high percentage in patients with chronic kidney diseases 29 (78.4) out of 37 (28.2%) such patients. There was significant association of chronic kidney diseases stages with drug-drug interactions, polypharmacy, dose error and prescribing drugs (p<0.05). The higher incidence of drug-related problems reflected irrational prescribing trends and deficiency of professional staff dealing with kidney disease patients.

Abstract
This study was planned to explore the in-vitro and in-vivo therapeutic significance of Paeonia emodi-mediated zinc oxide nanoparticles (ZnO NPs) against the Staphylococcus aureus and Escherichia coli. The texture parameters were derived from nitrogen adsorption-desorption data using Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) methods, and the surface area (SBET ) was found to be 214 m2 /g with a pore size of 2.3 nm. The crystallographic parameters were investigated through X-ray diffraction analysis, and the calculated crystallite size is 29.13 nm. The microstructure was examined through transmission and scanning electron microscopies (TEM and SEM, respectively), and the average particle size estimated from a TEM image is 44.40 nm. The chemical composition and attached function groups were identified through energy-dispersive X-ray and Fourier transform infrared spectroscopies. The in-vitro minimum inhibitory concentration (MIC) for both bacterial species results was found less than 2 μg/ml. The tolerance limit of mouse models was evaluated by the inoculation of different concentrations of ZnO suspension where the concentration above 23 ppm was proved lethal. The maximum infection was caused in mouse models by inoculation of 3 × 107 CFUs (Colony forming unit) of the both bacterial species. The concentration higher than 3 × 107 CFUs led to the ultimate death of the mice. The histopathological and hematological studies reveal that the after simultaneous inoculation of both ZnO NPs and bacterial suspensions (tolerated amount), no/negligible infection was found in the mice model.

Abstract
Increasing resistance to existing antibiotics by microbes is currently the biggest dilemma. Antimicrobial photodynamic therapy is a promising alternative for treatment of multidrug resistant infections. The aim of current study was to fabricate graphene quantum dots loaded with curcumin as photosensitizer for improved antimicrobial photodynamic therapy. The study involved fabrication of blank and curcumin-loaded graphene quantum dots, their characterizations (TEM, UV-visible & fluorescence emission spectra), cytotoxicity assay, ROS assay and investigation of enhanced antimicrobial photodynamic effect against resistant microbes. The fabrication of blank and loaded graphene quantum dots was confirmed by observation of peak shift and changes in peak intensity of blank graphene quantum dots, curcumin alone compared to curcumin loaded graphene quantum dots in UV-visible and fluoresce emission spectra. Cytotoxicity assay showed that 100 µM concentration was not toxic to NIH/3t3 fibroblasts. In ROS assay, the curcumin loaded formulation showed threefold increase in ROS production. Blue light (405 nm) irradiance of 30 J/cm2 and photosensitizer concentration of 100 µM showed ~3.5 log10 enhanced CUF reduction against Pseudomonas aeruginosa, MRSA, Escherichia coli, and Candida albicans. In conclusion, curcumin-loaded graphene quantum dots shoed enhanced antimicrobial photodynamic effects and can be used as an alternative effective treatment for resistant infections.

Abstract
Aim: This study was aimed to determine the virulent genes and antibiotic resistance patterns among circulating diarrheagenic Escherichia coli (DEC) pathotypes in a tertiary care health center in east of Nigeria.
Materials and Methods: Diarrheal stool samples were obtained from 80 children under 5 years and E. coli was isolated and identified using standard biochemical and molecular methods. Multiplex polymerase chain reaction (PCR) was used to detect eight virulent genes of DEC. Disk diffusion method was used to determine the antibiotic susceptibility of DEC.
Results: DEC infection was observed in 54 (68%) children among which ial gene for enteroinvasive E. coli (EIEC) (40% [n=22]) was commonly detected followed by eltA/eltB for enterotoxigenic E. coli (ETEC) (30% [n=16]), pCVD for enteroaggregative E. coli (EAEC) (20% [n=11]), and eaeA/bfpA for typical enteropathogenic E. coli (EPEC) (10% [n=5]). The DEC isolates phenotypically exhibited resistance for ampicillin (AMP) (44 [81%]), followed by ciprofloxacin (CIP)/ levofloxacin (LEV) (28 [52%]), cefoxitin (FOX) (11 [20%]), and amoxicillin-clavulanic acid (AMC) (6 [11%]). About 60% isolates of stable toxins-ETEC were resistant to AMC, CIP, and LEV while all the labile toxin-ETEC exhibited resistance to AMP. About 60% (n=6) resistance were seen in EAEC against ampicillin, AMC, FOX, CIP, and LEV. In EIEC, all the isolates (n=22) were resistant to AMP while 50% (n=11) were resistant to both CIP and LEV. All EPEC (n=5) were resistant to AMP, FOX, CIP, and LEV.
Conclusion: High frequency of virulent ial and eltA/eltB genes for EIEC and ETEC, respectively, suggests that they are the primary etiological agents of diarrhea in children among DEC pathotypes. Resistance of DEC to more than two classes of antibiotics indicate possible emergence of multidrug resistance.

Abstract
BACKGROUND Biofilm forming ability of Pseudomonas aeruginosa make them vulnerable, because it makes them recalcitrant against various antibiotics. Quorum sensing (QS) is cell density based signaling that helps in bacterial cell-cell communication, which regulated various virulence factors such as pigment and biofilm formation that contribute in the establishment of chronic infections. The interruption of QS is one of the effective approach to control various virulence factors. Present study was intended with the aim to authenticate antibiofilm potential in different solvents based extracts of selected medicinal plant species viz. Berginia ciliata, Clematis grata and Clematis viticella traditionally used by the inhabitants of Himalayan region of Pakistan to treat various pathogenic diseases. P. aeruginosa PAO1, an opportunistic pathogen and involves in various life-threatening infections specifically in immune deficient patients was used as a model pathogen. METHODS Plants were extracted in various organic (ethanol, methanol, acetone, ethyl acetate, hexane, chloroform) as well as in aqueous solvents and their ability to inhibit biofilm was measured. Biofilm of PAO1 was grown in Jensen's medium while growing at 30°C and crystal violet assay was performed to assess the biofilm inhibiting activity of plant extracts. RESULTS Solvents play a vital role in extraction of plant components and it was found that the plants in various solvents exhibit different activity against the PAO1 biofilm. Comparatively, 1% methanolic extract of B. ciliata (rhizome with skin), showed more than 80% inhibition of biofilm formation without effecting on the growth of the bacterium. Significant correlation between flavonoids content and antibiofilm activity in methanolic extract revealed the contribution of secondary metabolites in P. aeruginosa (PAO1) biofilm inhibition. CONCLUSION Our study revealed that plants under investigation more specifically B. ciliata could be a potential candidate for drug discovery to treat P. aeruginosa PAO1, induced infectious diseases especially for its biofilm treatment.

Abstract
The current study is an attempt to explore the effect of varying quantities of hydroxypropyl cellulose (HPC) polymer on carbamazepine (CBZ) cocrystal formation with dicarboxylic acid coformers i.e., malonic acid (MA), succinic acid (SA), glutaric acid (GA), and adipic acid (AA). The cocrystals were first prepared without polymer by slurry crystallization method and then tried with different quantities of the polymer. The prepared samples were characterized by Powder X-ray Diffraction (XRPD). The characterization results indicate that in methanol pure carbamazepine-malonic (CBZ-MA) and carbamazepine-adipic acid (CBZ-AA) cocrystal can be prepared, while in ethanol and acetone pure carbamazepine-succinic (CBZ-SA) and carbamazepine-glutaric acid (CBZ-GA) cocrystals can be obtained respectively. The same cocrystals were tried using HPC polymer in three different quantities. The characterization results showed that a higher quantity of HPC polymer transforms CBZ-MA cocrystal polymorph-I to polymorph-II. The CBZ-SA and CBZ-GA cocrystal formation somehow inhibited as the concentration of HPC polymer increases. But on the other side, the formation of CBZ-AA cocrystal utterly not inhibited in the presence of varying quantities of HPC polymer. Furthermore, 11 different quantities of HPC were tried to know about the inhibitory concentration of HPC on CBZ-AA cocrystal formation. The CBZ-AA cocrystal preparation was not inhibited even at higher quantities of HPC compared to the coformer. Additionally, the effect of three different quantities of HPC on the thermal stability of the CBZ-AA cocrystal was investigated. Moreover, the stability of pure CBZ at 92% relative humidity (RH) condition was compared to CBZ-AA cocrystal with and without HPC polymer. The CBZ-AA cocrystal with and without HPC polymer was more stable than pure CBZ.

Abstract
OBJECTIVES Thyroid Cancer is one of the rarest cancers but its prevalence has been increasing worldwide for the last couple of decades. METHODS The data collection tool was designed to assess knowledge, awareness, perception, and attitude towards preventive practices of thyroid cancer in Pakistani university students. The data were collected over a duration of six months and a total number of 3722 students participated. RESULTS The knowledge of risk factors of thyroid cancer was an important parameter of this study. The students who knew all the early signs of thyroid cancer were 28.7%. In this study, the independent variables such as age, gender, demographic location, and financial status were found to be highly significant with knowledge, attitude towards warning signs of cancer, and the perception of students about developing thyroid cancer. CONCLUSIONS The participants were found to have poor knowledge about early signs of thyroid cancer. The study participants perception, behavior, and attitude towards preventive practices of thyroid cancer were found inadequate and appropriate measures on a National level should be taken to enhance the knowledge about preventive practices of thyroid cancer. Increasing knowledge and awareness shall help decrease the overall morbidity and mortality linked with thyroid carcinomas and thyroid diseases.

Abstract
Abstract
Background
Multidrug-resistant bacteria are becoming more hazardous day by day for human health all over the world, and the scientific community is trying hard to resolve this issue by various approaches. One of the very common approaches is to bind drugs to nanoparticles and study enhanced antibacterial properties.
Objective
To compare simultaneously different types of nanoparticles, their concentration, bacterial strains and their incubation time intervals for each of the selected drug combination.
Methods
We have selected the most commonly used gold and silver nanoparticles and few examples from fluoroquinolone antibiotics to make their conjugates and study their efficacy against multidrug-resistant E. coli and S. aureus strains simultaneously, at different incubation time intervals and different concentration of nanoparticles.
Results
Gold nanoparticle hybrids do not show any significant effect. Silver nanoparticle hybrids show far better results, even at extremely low concentrations.
Conclusions
This unique and simple approach allows us to know the exact time intervals and concentration required for each nanoparticle combination to control the growth for any specific strain. This approach can be extended to any set of nanoparticles, drugs and bacterial strains for comparative purposes.

Abstract
Background Distemonanthus benthamianus is used in the Western part of Cameroon to treat diarrheal episodes and infections. This study assessed its trunk-bark extracts activity against enteropathogenic Escherichia coli 31 (EPEC 31)-induced diarrhea in rats. Methods Aqueous and methanolic extracts were analyzed through high-performance liquid chromatography (HPLC). In vitro minimum inhibitory and bactericidal concentrations (MICs/MBCs) were evaluated on Enterococcus faecalis (ATCC 10,541), E. coli (ATCC 6539), Klebsiella pneumoniae (ATCC 13,883), Salmonella typhi (ATCC 6539) strains and on Proteus mirabilis, Pseudomonas aeruginosa (PA 01) and Shigella flexneri isolates using the microdilution method. Diarrhea was induced by inoculating rats with EPEC 31 (1.5 × 108 CFU/mL; p.o). Serum transaminases level assay and enzyme-linked immunosorbent assay (ELISA) for cytokines determination were performed. Hematoxylin-eosin (H-E) staining was used for intestinal tissue analysis. Results HPLC fingerprints of extracts showed presence of gallic acid and other unidentified compounds. The lowest MIC of 256 µg/mL was obtained with methanolic extract. At 100 mg/kg, both extracts significantly (p<0.001) inhibited diarrhea, with the methanolic extract being the most active. In addition, the methanolic extract significantly (p<0.001) increased the relative mass of the liver compared to negative control (Tween-DMSO 8%). The aqueous extract (100 mg/kg) significantly (p<0.01) increased alanine aminotransferase (ALT) serum concentration; while the methanolic extract (100 mg/kg) exhibited similar effect over aspartate aminotransferase (AST). At 50 and 100 mg/kg, the methanolic extract significantly (p<0.05 and p<0.01) decreased the Interleukin-1β (IL-1β) serum level, compared to negative control (Tween-DMSO 8%). Serum level of tumor necrosis factor alpha (TNF-α) significantly (p<0.001) decreased with 100 mg/kg of aqueous extract and all doses of methanolic extract. Inhibition of inflammatory cells tissue infiltration and epithelial regeneration was highly noticed in the ileum and colon of extracts-treated rats than in ciprofloxacin-treated animals. Conclusion These findings suggest that D. benthamianus trunk-bark extracts displayed therapeutic effects against infectious diarrhea in rats.

Abstract
Purpose: To investigate the effects of zinc oxide nanoparticles (ZnO NPs) on chloroquine (CQ)-induced itching, and overall behavior of mice after oral administration of ZnO NPs of various sizes and doses. Background: With the wide-spread use of ZnO NPs in pharmaceuticals and cosmetics, concerns about their safety and toxicity are also increasing. Multiple aspects of ZnO NPs regarding cytotoxicity and tolerability are under investigation globally. Still, a clear conclusion about their safety has not been reached. Chloroquine phosphate is an antimalarial with known side effects of itching in humans and animals. In this study, CQ was used to induce itching in mice, and the effects of ZnO NPs on scratching and other neurological behavior of mice were observed. Methods: Female BALB/c mice were divided into eleven groups of six mice each. ZnO NPs of various sizes and doses were administered orally 1 hour before CQ (32 mg/kg body weight) was administered subcutaneously. The effect of ZnO NPs on CQ-induced pruritus was observed for the next 30 minutes. Simultaneously, overall behavioral changes (socialization and locomotion) were also recorded using a video camera. Results: A significant reduction (P˂0.001) in scratching bouts was observed at all three doses of ZnO NPs (particle sizes 100, 30 nm, and green synthesized 30 nm). Locomotion was reduced significantly (P˂0.001) in ZnO NPs-treated groups in comparison to normal saline and CQ group, additionally, a significant increase in socialization (P˂0.05) was observed in ZnO NP-treated groups as compared to CQ group. Conclusion: ZnO NPs, instead of aggravating the dermatological condition, ameliorated the pruritus. All sizes of ZnO NPs used significantly improved socialization among mice and reduced locomotion activity.

Abstract
OBJECTIVE To evaluate the knowledge, attitude and practice of self-medication in medical undergraduate students. METHODS This cross-sectional questionnaire-based survey was conducted from January to June, 2017, among undergraduate students of Ayub Teaching Hospital, Women Medical College, International Medical College and Frontier Medical College in Abbottabad, Pakistan. The sample comprised students of first, second, third, fourth and fifth professional year. Data was collected using self-generated questionnaire. RESULTS Of the 400 subjects approached, 300(75%) returned the questionnaire fully completed. Of them, 208 (69.3%) were females and 92(30.66%) were males. The most common age group was 22-25 years 182(60.7%). Self-medication was found to be prevalent among 297(99%) subjects and 139(46.3%) respondents had practised self-medication in the preceding 6 months more than two times. Over-the-counter drugs were commonly used for the self-medication in 295(98.3%) cases. Overall, 285(95%) respondents had a positive attitude towards self-medication. Media was found to be the most common source of information for 93(31%) cases. CONCLUSIONS High prevalence of self-medication was noticed, with over-the-counter drugs being the most commonly used. Proper educational awareness programmes about self-medication can control the issue.

Abstract
OBJECTIVE To investigate the efficacy and impact of Protection Against Harassment of Women at Workplace Act 2010 in the public health sector in its socio-legal perspective. METHODS This cross-sectional study was conducted from July to December 2014 in Abbottabad, Pakistan, and comprised subjects selected from 53 basic health units managed by the government. SPSS 20 was used for statistical analysis. RESULTS Of the 450 questionnaires, 430(96.6%) were returned duly filled. Overall, 40% male (120 respondents) and 26% female (34 respondents) knew about the Act. Besides, 39% males (117 respondents) and 63% females (82 respondents) appeared unsatisfied with the complaint mechanism prescribed in the Act; all the respondents established that no case had been registered after the introduction of the Act. Overall, 31% males (93 respondents) and 57% females (74 respondents) thought that without the health governance commitment and social support structure the Act could not work. CONCLUSIONS The Protection Against Harassment of Women at Workplace Act 2010 was considered ineffective by the respondents who were concerned about the lack of social support system for the Act.

Background Enterococci have emerged as more virulent and multidrug-resistant in community and hospital settings. The emergence of vancomycin resistant enterococci (VRE) in hospitals has posed a serious threat to public health. The widespread use of antibiotics to treat VRE infections has resulted in the development of resistant forms of these organisms. Objectives Present study deals with the efficacy of antibiotic-nanoparticle combination against clinical isolates of VRE. This study has effectively evaluated the anti-enterococcal activity of metallic nanoparticles and their combination with antibiotics with the aim to search for new biocidal combinations. Materials and Methods Initially, the isolates were identified by various biochemical tests and also by PCR, targeting ddl, vanA and vanB genes. Antibiotic susceptibility testing was carried out by disc diffusion method. Minimum inhibitory concentration (MIC) of both antibiotics and metal nanoparticles against VRE was done using broth dilution method. On the basis of MICs, a combination of both antibiotics and nanoparticles was used by physical mixing of antibiotics and different concentrations of nanoparticles. Results The MIC of metal nanoparticles were found in the range of 0.31 - 30 mM. The combination of both antibiotics and nanoparticles has effectively reduced the MICs of ciprofloxacin from 16 - 256 μg/mL to 2 - 16 μg/mL, erythromycin 1024 - 2048 μg/mL to 128 - 512 μg/mL, methicillin 32 - 256 μg/mL to 8 - 64 μg/mL and vancomycin 2 - 512 μg/mL to 0.5 - 64 μg/mL. Conclusions Among the nanoparticles, ZnO was found as a potent metallic nanoparticle which effectively reduced the MIC upon combination with the antibiotics. The combination exhibited enhanced bactericidal activity against multidrug resistant clinical strains of VRE with dose dependency. Further extensive study on this aspect can prove their beneficial clinical use against resistant pathogens to combat increasing resistance to antibiotics.

Abstract
Abstract: The objective of this study was to fabricate topical formulations of diclofenac diethylamine (DD) using isopropyl myristate (IPM) and isopropyl palmitate (IPP) as permeation enhancers. Franz cell and bacterial cellulose were used as analytical instrument and diffusion membrane, respectively. Permeation enhancers exhibited significant effect on the permeation characteristics of DD. It was concluded from the results that improved permeation of DD was observed when IPP was used as enhancer.

Abstract
BACKGROUND Enterococci normally inhabit the intestinal tract of humans and are also a potential pathogen in causing nosocomial infections. The increase in antibiotic resistance and transfer of antibiotic resistance gene to Staphylococcus aureus (S. aureus) due to co-colonization has increased its importance in research. The aim of the study was to evaluate local epidemiology of nasal and rectal colonization with Enterococcus faecalis (E. faecalis) and Enterococcus faecium (E. faecium) in patients of Paediatrics Intensive Care Unit (PICU) and correlation with clinical and socioeconomic factors. METHODS The nasal and perirectal swab samples were collected from 110 patients admitted in PICUs of three tertiary care hospitals of Rawalpindi Medical College, Pakistan. The identification of enterococci was done by biochemical tests and by PCR for ddl, vanA and vanB genes. Antibiotic susceptibility testing was performed by disc diffusion and MICs were determined for vancomycin, tetracycline, ciprofloxacin and oxacillin only. RESULTS Out of 220 nasal and perirectal samples, 09 vancomycin-resistant enterococci (VRE) and 76 vancomycin-susceptible enterococci (VSE), consisting of 40 E. faecalis and 45 E. faecium were isolated. PCR successfully identified both species with ddl primers and VRE with vanA primer. With disc diffusion method, all isolates were resistant to most of the antibiotics tested except linezolid, quinupristin/dalfopristin, teicoplanin and vancomycin. VRE showed resistance to teicoplanin and vancomycin both and none was resistant to linezolid and quinupristin/dalfopristin. Generally, E. faecium isolates were more resistant than E. faecalis. MICs of vancomycin for nasal and perirectal VRE were 512 mg/L and 64 to 512 mg/L respectively. VRE were more in patients with prolonged hospitalization, from urban localities and those having pneumonia. CONCLUSION Present study reveals high colonization and antibiotic resistance in enterococcal isolates from nasal and perirectal area. Nasal colonization by enterococci in PICU is more alarming as VRE may cause infection and can transfer this resistance gene to other microorganisms like S. aureus.
