Uropathogenic Bacteria

Aims: This study aimed to identify the prevalence and antimicrobial susceptibility of the commonly isolated uropathogens in Sana’a city, Yemen. Study Design:  A cross-sectional and descriptive study. Place and Duration of Study: The study was carried out at the hospitals and clinics of Sana'a city, Yemen between October 2016 and March 2017. Methodology: Clean-catch mid-stream urine samples were collected to detect the most common uropathogenic bacteria and their antibiotic susceptibility using Kirby Bauer standardized method. Results: Urine cultures yielded 170 significant bacterial growths of uropathogens. Escherichia coli was the most often isolated pathogen (43.5%), followed by Klebsiella pneumoniae (24.7%), Pseudomonas aeruginosa (20.0%) and Staphylococcus aureus (11.8%). The overall sensitivity was high to an excellent pattern for Carbapenems, Nitrofurantoin, Amikacin, and Piperacillin-Tazobactam. Escherichia coli shows an excellent sensitivity (88%) for Nitrofurantoin and Imipenem, followed by (85%) Ertapenem. Pseudomonas aeruginosa exhibited moderate resistance to Carbapenems, Moxifloxacin, and Piperacillin-Tazobactam in this study. Staphylococcus aureus was more vulnerable to all Quinolones except Nalidixic acid and it displays a high sensitivity pattern, 90% for both Nitrofurantoin and Gentamicin, 83% for Penicillin, 80% for both Minocycline. Antibiogram of isolated organisms revealed that there was resistance to two and more antimicrobials. Conclusion: In this study, we observe a high resistance rates to Beta-lactam, Quinolones, and Macrolides antibiotics. Nevertheless, most uropathogenic isolates were still sensitive to Nitrofurantoin, Imipenem, Ertapenem, and Amikacin, they considered as a proper antibiotics for empirical therapy of UTIs. Establishment of antibiogram of locally isolated organisms is necessary to avoid indiscriminating use of antibiotic and to decrease the resistance rate in our community.

Background: Pseudomonas aeruginosa, a gram-negative pathogen commonly associated with nosocomial infections is the most widespread multidrug-resistant pathogen causing pneumonia in hospitalized patients. Inadequate empirical therapy has been associated with high mortality and morbidity. Objective: To evaluate and analyze the antimicrobial susceptibility pattern of P. aeruginosa in respiratory infections in a tertiary care hospital.Methods: The study was carried out at Kasturba Hospital, Manipal from Jan 2011 to Dec 2011. Specimens of 63 in-patients were analyzed who were culture positive for P. aeruginosa.Results: Majority of patients were aged above 40yrs with a male preponderance. Specimens were taken from patients who were diagnosed with bronchiectasis, pneumonia, COPD, bronchial asthma etc. Overall the organism was most sensitive to carbapenems (87.3%) followed by cefoperazone-sulbactam combination (85.7%). Sensitivity to ceftazidime and cefepime was equal (82.5%) and was more when compared to piperacillin-tazobactam (81.5%). Overall resistance rate was highest for fluoroquinolones (23.8%) followed by aztreonam (22.2%).Conclusions: Hence we would like to recommend cefoperazone-sulbactam as the preferred antipseudomonal agent and carbapenems as reserved drugs in treating pseudomonal lung infections. Use of fluoroquinolones and aztreonam as monotherapy in resistant P. aeruginosa infections should be restricted.

Beta-lactam antibiotic resistance can occur in ESBL-producing bacteria such as E.coli and K.pneumoniae, which can cause UTI. One of the risk factors for infection is the non-intensive care space density level. The objective of this study was to determine the sensitivity pattern of ESBL-producing bacteria in urine specimens of patients in the non-intensive care of Ulin General Hospital, Banjarmasin, in the period of 2016-2018. A descriptive study with a cross-sectional design using data results of urine culture and antibiotic susceptibility patterns data in non-intensive care patients at Ulin General Hospital from 2016 to 2018. The urine test results showed 96 positive isolates of ESBL-producing bacteria, consisting of ESBL-E.coli (69.8%) and ESBL-K.pneumonia (30.2%). Antibiotics with low sensitivity tests were Penicillin, Cephalosporin, Monobactam, and Penicillin/beta-lactam inhibitor combinations. Contrastingly, antibiotics with high sensitivity were Aminoglycoside, Carbapenem, and Glycylcycline. It was concluded from this study that the ESBL-producing bacteria in urine specimens for non-intensive care patients of Banjarmasin Ulin General Hospital in the period of 2016-2018 showed varying sensitivity to antibiotics

Sensitivity Pattern

Over the last few years, there has been a decrease in amount of effective antibiotics, coincide with the lack of newantibiotics relevant for the treatment of Gram negative multi-drug resistant organisms infections. This problem can beovercome by the assessment and re-introduction of old antibiotics such as fosfomycin. Fosfomycin is a broad spectrumantibiotic that is bactericidal. This study aimed to find out the sensitivity pattern of clinical isolate multi-drug resistantGram negative bacteria to fosfomycin with descriptive cross sectional method. The sample used in this study wasclinical isolates collection of Microbiology Laboratory Faculty of Medicine, University of Riau from Hospitals inPekanbaru. The result showedsensitivity to fosfomycin Escherichia coli producing ESBL (88%), Klebsiella pneumoniaeproducing ESBL (95%), Acinotobacter baumannii resistant meropenem (27%), Pseudomonas aeruginosa resistantmeropenem (36%) and K.pneumoniae resistant meropenem (70%). Fosfomycin can be used as alternative therapy forinfections caused by Gram-negative Multi-drug resistant organisms.

Objective. To identify socioeconomic factors associated with antimicrobial resistance of Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli in Chilean hospitals (2008–2017). Methods. We reviewed the scientific literature on socioeconomic factors associated with the emergence and dissemination of antimicrobial resistance. Using multivariate regression, we tested findings from the literature drawing from a longitudinal dataset on antimicrobial resistance from 41 major private and public hospitals and a nationally representative household survey in Chile (2008–2017). We estimated resistance rates for three priority antibiotic–bacterium pairs, as defined by the Organisation for Economic Co-operation and Development; i.e., imipenem and meropenem resistant P. aeruginosa, cloxacillin resistant S. aureus, and cefotaxime and ciprofloxacin resistant E. coli. Results. Evidence from the literature review suggests poverty and material deprivation are important risk factors for the emergence and transmission of antimicrobial resistance. Most studies found that worse socioeconomic indicators were associated with higher rates of antimicrobial resistance. Our analysis showed an overall antimicrobial resistance rate of 32.5%, with the highest rates for S. aureus (40.6%) and the lowest for E. coli (25.7%). We found a small but consistent negative association between socioeconomic factors (income, education, and occupation) and overall antimicrobial resistance in univariate (p < 0.01) and multivariate analyses (p < 0.01), driven by resistant P. aeruginosa and S. aureus. Conclusion. Socioeconomic factors beyond health care and hospital settings may affect the emergence and dissemination of antimicrobial resistance. Preventing and controlling antimicrobial resistance requires efforts above and beyond reducing antibiotic consumption.

Abstract Objectives: To determine frequency of Endogenous Methicillin Resistant Staphylococcus aureus (MRSA) in pre operative patients and its frequency in Surgical Site Infections (SSIs) Post operatively. Methods: It was a descriptive cross sectional conducted at Department of Microbiology, Fauji Foundation Hospital Rawalpindi (FFH), Pakistan. Samples were collected from 1st November-31st May 2018. Total 75 samples were collected during the period. Consecutive non-probability sampling technique was utilized. Specimens were collected from nose, axilla and groin of preoperative patients. Methicillin Resistant Staphylococcus aureus was identified if only isolated from these sites. Patients were followed till his/her discharge from the hospital and if they developed infection post operatively, pus specimen from infected site was also collected and identified.Results: Out of 75 specimen preoperatively, 14.7% (n=11) were identified as endogenous MRSA. From these, 44% (n=33) developed Surgical site infections (SSIs), among them 57% (n=19) were MRSA (09 endogenous, 10 exogenous), 21.2% (n=7) were Escherichia coli, 9.1% (n=3) were Klebsiella pneumoniae, 9.1% (n=3) were Enterococcus faecalis and 3% (n=1) was Methicillin Sensitive Staphylococcus aureus. Conclusion:  The results of this study determined that Endogenous Methicillin Resistant Staphylococcus aureus (MRSA) could be isolated from patients going for surgery if microbiological screening was done at the time of admission. This could prevent patients from Surgical Site Infection Post operatively by these endogenous MRSA. This search and wipe out strategy is able to curtail the events of outbreak, reduce hospital stay and decrease budget of the hospital by providing guidance in choice of empirical therapy for infection.

Activité Antibactérienne

Ce travail vise l’étude de l’activité antibactérienne de l’huile essentielle (HE) de Pelargoniumx asperum et de la bactériocine, la nisine seul et en combinaison vis-à-vis de six bactéries dont quatre sont multirésistantes d’origine clinique. L’activité antibactérienne in vitro a été évaluée par la méthode de diffusion sur gélose. La concentration minimale inhibitrice (CMI) est aussi déterminée pour HE. Les résultats ont révélé une activité antibactérienne significative exercée par HE visà-vis de Staphylococcus aureus (ATCC 43300), Staphylococcus aureus et Escherichia coli avec des diamètres d’inhibition de 36,00 ; 22,50 et 40,00 mm, respectivement. Cependant, l’HE de Pelargonium asperum a montré une activité antibactérienne supérieure par rapport à la nisine. Les valeurs des CMI rapportées dans cette étude sont comprises entre 1,98–3,96 μl/ml. Les combinaisons réalisées entre HE et la nisine ont montré un effet additif vis-à-vis de Escherichia coli (ATCC 25922) avec (50 % HE Pelargonium asperum + 50 % nisine). Par contre, nous avons enregistré une synergie vis-à-vis de Klebsiella pneumoniae avec (75 % HE Pelargonium asperum + 25 % nisine) et contre Pseudomonas aeruginosa avec les trois combinaisons testées. Les résultats obtenus permettent de dire que l’HE de Pelargonium asperum possède une activité antibactérienne ainsi que sa combinaison avec la nisine pourrait représenter une bonne alternative pour la lutte contre l’antibiorésistance.

The present study was carried out to determine, for the first time, the chemical composition and antibacterial activity of essential oils derived from the aerial parts of three aromatic plants Thymus algeriensis Boiss & Reut, Rosmarinus officinalis L., and Salvia officinalis L. growing under semiarid conditions. The essential oils were chemically analyzed and identified by gas chromatography (GC) and GC/ mass spectrometry (GC/MS) and their antimicrobial activity was individually evaluated against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa using both agar disk diffusion and agar dilution methods. The major constituents of Thymus algeriensis essential oil were identified as camphor (13.62%), 1,8-cineol (6.00%), borneol (5.74%), viridiflorol (4.00%), and linalool (3.93%). For Rosmarinus officinalis essential oil, 48 compounds were characterized, of which the main constituents were camphor (17.09%), Z-β-ocimene (10.88%), isoborneol (9.68%), α-bisabolol (7.89%), and borneol (5.11%). While, Salvia officinalis essential oil was characterized by β-thujone (16.44%), followed by viridiflorol (10.93%), camphor (8.99%), 1,8-cineol (8.11%), trans-caryophyllene (5.85%), and α-humulene (4.69%) as the major components. Notably, results from antibacterial screening indicated that Thymus algeriensis and Salvia officinalis essential oils exhibited a strong inhibitory effect against both Escherichia coli and Staphylococcus aureus compared to Rosmarinus officinalis essential oil. Further, less activity was recorded against Pseudomonas aeruginosa for the three tested essential oils.
