Background. There is a rapid deterioration in the effectiveness of antibiotics due to the global prevalence of bacterial antimicrobial resistance (AMR). AMR can cause an increase in mortality and morbidity due to treatment failures and a lack of effective therapy. Objective. The purpose of this study was to evaluate the AMR pattern of different bacterial isolates at hospitals and laboratories. Materials and Methods. A cross-sectional study from March 2019 to June 2019 was conducted at different governmental and private hospitals and laboratories in Aden, Yemen. Age, sex, specimen type, bacterial isolates, and antibiotic susceptibility pattern were collected using a data extraction sheet. Descriptive statistics were used for data analysis. Result. Data were recorded for 412 patients from whom 20 clinical specimens were collected and analyzed. The most common bacteria isolated were Staphylococcus spp. (n=172, 41.74%), E. coli (n=164, 39.80%), Pseudomonas spp. (n=37, 8.98%), and Klebsiella pneumoniae (n=18, 4.36%); other bacteria were less common. The overall bacterial resistance was highest against the combination of sulfamethoxazole with trimethoprim (73.12%), followed by amoxicillin and clavulanate (65.19%). The cephalosporin antibiotics also showed high resistance rates. The study also showed moderate bacterial resistance to gentamycin (32.65%), azithromycin (29.92%), cefoxitin (62.65%), and ciprofloxacin (25.60%). Ertapenem (16.67%) and levofloxacin (15.56%) had the lowest resistance rates. Conclusion. There was a high percentage of bacteria resistant to several antibiotics. Antibiotic susceptibility testing is a prerequisite guide for the selection of appropriate antibiotic therapy for bacterial infections.

ObjectiveAntibiotics have been routinely used for several decades againstPropionibacterium acnes(P. acnes), but antibiotic resistance ofP. acnesis becoming a global problem. Only one related Chinese study is available. The aim of this study was to assess the antibiotic susceptibility ofP. acnesobtained from patients with acne in Southwest China.DesignThis was a prospective cross-sectional study. Cutaneous samples were obtained from acne lesions on the face of 375 patients. Samples were cultured in anaerobic medium to identify the presence ofP. acnes. Susceptibility tests of isolatedP. acneswere performed for tetracycline, doxycycline, clindamycin, erythromycin, azithromycin and clarithromycin using the Epsilometer test.ResultsP. acneswas isolated from 227 patients; 224 isolates (98.7%) were susceptible to doxycycline and 220 (96.9%) were susceptible to tetracycline, followed by clindamycin and clarithromycin in 101 (44.5%) and 102 (44.93%) isolates, respectively. Susceptibility ofP. acneswas detected for erythromycin in 96 (42.3%) patients, followed by azithromycin in 94 (41.4%). Subjects who received antibiotics (topical and oral) had higher frequencies of antibiotic-resistantP. acnesas well as increased antibiotic minimum inhibitory concentrations compared with patients without antibiotic treatment.ConclusionsP. acneswas highly sensitive to cyclines (doxycycline and tetracycline).P. acnesshowed higher resistance rates to macrolides–lincosamides–streptogramins antibiotics (such as erythromycin, azithromycin, clarithromycin and clindamycin). The irrational use of antibiotics for acne treatment is probably a problem in China and elsewhere. These results suggest that dermatologists should be more prudent in prescribing antibiotics for acne.

BACKGROUND: Urinary tract infection (UTI) is a collective term used to describe the microbial invasion of any part of the urinary tract, which consists of the kidneys, ureters, bladder, and urethra. It is one of the most common bacterial infections in both sexes with a predilection in females. OBJECTIVES: The objectives of the study were to isolate the bacteria causing UTI and the highest resistance microorganisms with resistance rates to different antibiotics. STUDY DESIGN: This was a cross-sectional study.METHODS: A cross-sectional study with a sample size of 1000 patients both inpatient and outpatient referred to the laboratory of Al-Kindy Teaching Hospital for urine culture and antibiotic susceptibility examination. RESULTS: Of 1000 samples, 318 (31.8%) urine samples were found positive while 682 (68.2%) were negative. Females with bacteriuria held the highest percentage (72.3%) over males (27.7%). Most frequent pathogen was Escherichia coli (40.5%) followed by Klebsiella pneumonia (25.7%) which together accounted for 66.2% of the total uropathogens. The uropathogenic bacterial isolates showed different resistance rates to antimicrobial agents: Cefixime (74%), ticarcillin/clavulanic acid (73.87%), rifampin (68.75%), ceftriaxone (60.31%), cefepime (44.44%), ciprofloxacin (43.65%), aztreonam (33.78%), nitrofurantoin (29.61%), gentamicin (25.64%), and amikacin (7.31%) being the most effective with a susceptibility rate of (89.63%). CONCLUSIONS: E. coli remains to be the most frequent bacterial uropathogen causing urinary infections. Effective drug may be in the clinical study, in microbiology is only that bacteria were most susceptible to amikacin. β-lactams have the highest resistance rates, and the most resistance antibiotic in this study is cefixime.

A single-center cross-sectional study was conducted to describe the use of ceftaroline in a large teaching hospital in Northern Italy, during a period also including the first months of the coronavirus disease 2019 (COVID-19) pandemic. The primary objective was to describe the use of ceftaroline in terms of indications and characteristics of patients. A secondary objective was to describe the rate of favorable clinical response in patients with bloodstream infections (BSI) due to methicillin-resistant Staphylococcus aureus (MRSA-BSI) receiving ceftaroline. Overall, 200 patients were included in the study. Most of them had COVID-19 (83%, 165/200) and were hospitalized in medical wards (78%, 155/200). Included patients with COVID-19 pneumonia were given empirical ceftaroline in the suspicion of bacterial co-infection or superinfection. Among patients with MRSA-BSI, ceftaroline was used as a first-line therapy and salvage therapy in 25% (3/12) and 75% (9/12) of cases, respectively, and as a monotherapy or in combination with daptomycin in 58% (7/12) and 42% (5/12) of patients, respectively. A favorable response was registered in 67% (8/12) of patients. Improving etiological diagnosis of bacterial infections is essential to optimize the use of ceftaroline in COVID-19 patients. The use of ceftaroline for MRSA-BSI, either as a monotherapy or in combination with other anti-MRSA agents, showed promising rates of favorable response.

Factors Influencing

Factors reported in the literature associated with inappropriate prescribing of antimicrobials include physicians with less experience, uncertain diagnosis, and patient caregiver influences on physicians’ decisions. Monitoring antimicrobial resistance is critical for identifying emerging resistance patterns, developing, and assessing the effectiveness of mitigation strategies. Improvement in prescribing antimicrobials would minimize the risk of resistance and, consequently, improve patients’ clinical and health outcomes. The purpose of the study is to delineate factors associated with antimicrobial resistance, describe the factors influencing prescriber’s choice during prescribing of antimicrobial, and examine factors related to consequences of inappropriate prescribing of antimicrobial. A cross-sectional study was conducted among healthcare providers (190) in six tertiary hospitals in the Eastern province of Saudi Arabia. The research panel has developed, validated, and piloted survey specific with closed-ended questions. A value of p < 0.05 was considered to be statistically significant. All data analysis was performed using the Statistical Package for Social Sciences (IBM SPSS version 23.0). 72.7% of the respondents have agreed that poor skills and knowledge are key factors that contribute to the inappropriate prescribing of antimicrobials. All of the respondents acknowledged effectiveness, previous experience with the antimicrobial, and reading scientific materials (such as books, articles, and the internet) as being key factors influencing physicians’ choice during antimicrobial prescribing. The current study has identified comprehensive education and training needs for healthcare providers about antimicrobial resistance. Using antimicrobials unnecessarily, insufficient duration of antimicrobial use, and using broad spectrum antimicrobials were reported to be common practices. Furthermore, poor skills and knowledge were a key factor that contributed to the inappropriate use and overuse of antimicrobials, and the use of antimicrobials without a physician’s prescription (i.e., self-medication) represent key factors which contribute to AMR from participants’ perspectives. Furthermore, internal policy and guidelines are needed to ensure that the antimicrobials are prescribed in accordance with standard protocols and clinical guidelines.

Aim: There is an ongoing debate as to what extent antimicrobial resistance (AMR) can be transmitted from dietary to humans via the consumption of food products. We investigated this association between dietary and global spreading carbapenem-resistant gene blaNDM Methods: We did a cross-sectional study to assess the risk factors for carrier of blaNDM in health community. Healthy adults were recruited from the residents attending Community Healthcare Service in Shenzhen City (Guangdong Province, China), through 1February 2018 to 31December 2019, and 718 pre-participants were included in this study. Questionnaire were obtained and the qualitative food frequency questionnaire (Q-FFQ) were used to assess dietary intake. qPCR was applied to confirm the carrier of blaNDM in participants’fecal samples. Multivariable logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (95% CI) of each outcome according to each dietary factor before and after prosperity score matching (PSM). Results: we showed that a high intake of coarse grain (OR 1.003; 95% CI 1.001–1.005, p < 0.01) and root and tuber crops (OR 1.003; 95% CI 1.001–1.004, p < 0.05) were independent risk factor for blaNDM carrier in health communities, suggesting a possible transfer of AMRbetweendietary andhumans. Surprisingly, we also showed an association between a higher intake of poultry as a protective, which may be explained by the beneficial effects on the gut microbiota. Conclusion: Dietary factors such as intake of coarse grain, root and tuber crops and poultry were associated with blaNDM carrier in health communities. The influence of dietary factorson blaNDM carrier in the present study provides insights for the tangible dietary advice with guidelines to the routine of people with the risk of blaNDM carrier. This demonstrates the role of dietary intake in the prevention of blaNDM carrier, since prevention is the best way to control modifiable risk factors. A lower carrier rate of blaNDM is helpful to reduce the possibility of transmission and pathogenicity. Further studies on food, microbiota and antimicrobial resistance are necessary to confirm this possible association and unravel underlying mechanisms.

Background:Urinary tract infection is the most common bacterial infections in humans and serious health problem in many parts of the world. It has become more complicated in treatment due to different pathogens and increasing resistant to antimicrobial agents. This study aims to investigate the prevalence of urinary tract infection and antibiotic susceptibility patterns of pathogens among the patients attending in B & B hospital Nepal.Materials and Methods:A hospital based cross sectional study was conducted in between April 2010 to March 2011. Urine samples were collected from clinically suspected patients and tested bacteriologically using standard procedures. Antimicrobial susceptibility test was performed for isolated pathogen using the Kirby-Bauer disk diffusion method according to Clinical and Laboratory Standards Institute guidelines.Results:Out of 1260 examined specimens 25.24 % were positive and majority 61.64% were females.  The most common pathogens isolated were Escherichia coli (66.67%), Enterococcus (7.55%) and Staphylococcus (6.60 %). The drug resistant among the positive cases were reported. The highest resistant of positive cases was found with Cefexime (87.88%) and Enterococcus with Ampicillin (66.67%) and Staphyllococcus with Cloxacillin (66.67%). The highest susceptibility was for Vancomycin and Ampicillin i.e. 33.33% in each.Conclusion:The findings showed that E. coli isolates were the predominant pathogen and the presence of bacterial isolates with very high resistance to the commonly prescribed drugs. As drug resistance among bacterial pathogens is an evolving process and serious issue. Therefore, routine surveillance and monitoring studies should be conducted to provide physicians knowledge on the updated and most effective empirical treatment of UTIs. Asian Journal of Medical Sciences Vol.7(5) 2016 47-51
