Rational Use Of Antibiotics

Antibiotics are one of the most commonly prescribed drugs today. Rational use of antibiotics is therefore extremely important as their injudicious use can adversely affect the patient. Drug Utilization Evaluation (DUE) is a system of ongoing systematic criteria based evaluation of drug that will help to ensure that medicines are used appropriately. It is drug/disease specific and can be structured so that it will assess the actual process of prescribing, dispensing, or administration of drug. The retrospective study was conducted At Pk Das Institute of Medical Sciences, Palakkad, Kerala for a duration of 6 months (February 2017 - January 2018). A source of data includes Patient case sheets &medication charts, nursing charts, culture & sensitivity reports. The inclusion criterion includes Patients aged between 18- 80 year, prescribed with oral and parenteral antibiotics. . On analyzing the gender, male gender (n= 111, 55.5%) were higher in numbers as compared to female counterparts (n=89, 44.5%). In our study the majority of the patients prescribed with antibiotics were with the clinical assessment of COPD (n=39, 19.5%), UTI (n=37, 18.5%) and LRTI (n=28, 14%), Bronchial asthma (n=19, 9.5%) respectively. On analyzing the data based on antibiotic sensitivity test, antibiotic test were performed and followed in (n=64,32%)prescriptions and in (n=47,23.5%)prescriptions were test is not followed respectively. In (n=89,44.5%) prescriptions, antibiotic sensitivity test is not performed. On analysis of antibiotics prescribed, the most commonly prescribed antibiotics were cephalosporins, of these ceftriaxone was highly prescribed of all (n=95). The high percentage of antibiotic prescriptions may indicate a high probability of irrational use. This study also point out irrational use of antibiotics are more leading to resistance, misuse and serious problems. So certain strategies should be put forward to strengthen rational use of antibiotics. Keywords: Antibiotics, Antibiotic Susceptibility Test, Irrational use, Resistance

Biofilms formation by pathogens microbial Control considered important in medical research because it is the hazarded virulence factor leading to becoming difficult to treat because of its high resistance to antimicrobials. Glycopeptide antibiotic a (Vancomycin) and the commercial bacteriocin (Nisin A) were used to comparative with purification bacteriocin (MRSAcin) against MRSA biofilm. One hundred food samples were collected from Baghdad markets from July 2016 to September 2016, including (cheese, yogurt, raw milk, fried meat, grilled meat, and beef burger). All samples were cultures; S. aureus was confirmation by macroscopic culture and microscopic examination, in addition to biochemical tests. Methicillin resistance S. asureus (MRSA) were identification by antibiotic sensitivity test (AST), Vitek 2 system. The result shown the 60(60%) isolate were identified as S. aureus and 45(75%) gave positive result as MRSA isolate, M13 isolate was chosen as MRSA isolates highest biofilm formation for treatment with MRSAcin, Nisin A(bacteriocin) and Vancomycin (antibiotic) to compared the more antimicrobial have bacteriocidal effect. The sensitivity test uses to determine the effect of MRSAcin, Nisin A, and Vancomycin MIC on MRSA planktonic cell by (WDA). The new study shows the impacts of new kind Pure Bacteriocins (MRSAcin) from methicillin-resistant S. aureus (MRSA) highly effects then (Vancomycin and Nisin A) at different concentration. In a current study aimed to suggest new Bacteriocin is potent highly for the treatment of resistant bacteria biofilm infections in food preservatives

The Individual

Currently, one of the priority medical and social problems is the optimization of treatment methods for pyoderma associated with Streptococcus pyogenes — group A streptococcus (GAS). To date, the proportion of pyoderma, the etiological factor of which is Streptococcus pyogenes, is about 6 % of all skin diseases and is in the range from 17.9 to 43.9 % of all dermatoses. Role of the bacterial factor in the development of streptococcal pyoderma is obvious. Traditional treatment complex includes antibacterial drugs selected individually, taking into account the antibiotic sensitivity of pathognomonic bacteria, and it is not always effective. Currently implemented immunocorrection methods often do not take into account specific immunological features of the disease, the individual, and the fact that the skin performs the function of not only a mechanical barrier, but it is also an immunocompetent organ. Such an approach makes it necessary to conduct additional studies clarifying the role of factors of innate and adaptive immunity, intercellular mediators and antioxidant defense system, that allow to optimize the treatment of this pathology.

Background: Penicillin resistance among Staphylococcus aureus commonly encountered in the hospital admitted patients. Detection of antibiotic sensitivity in hospital acquired methicillin resistant Staphylococcus aureus infections is important as it has great influence on empiric antibiotic prescription, successful control of infection, prevention of spread of disease and successful patient management. This study aimed to detect the frequency of HA-MRSA from pus samples in a hospital setup with assessment of their antibiotic susceptibility patterns. Method: A cross-sectional study was conducted in the Microbiology department of Basic Medical Science Institute, JPMC, Karachi from January 2015 until December 2015. Pus samples from surgical site wounds, skin lesions, abscesses from surgical and medical wards and ICUs were collected. According to the standards given by CLSI 2014, MRSA testing of the samples was done and susceptibility testing for antibiotics was performed. Inducible clindamycin resistance was detected by D-Test; E Test. determined MIC (minimum inhibitory concentration) for vancomycin. The data was analyzed by SPSS version 16. Result: Out of the 149 MRSA identified from the pus samples, 106 (71.14%) samples were HA-MRSA. The number of male patients was more than the female patients (67.66%). Out of the 106 HA-MRSA, 91(85.8%) were sensitive to TMP/SMX, 98(92.5%) to rifampicin, 12(11.6%) to gentamicin, 85(80.2%) to tetracycline, 11(10.4%) to erythromycin, 37(34.9%) to clindamycin, 20(18.9%) to ciprofloxacin, 106 (100%) to both vancomycin and linezolid. Conclusion: HA-MRSA showed sensitivity to TMP/SMX and vancomycin making them effective drugs to use in combination in superficial infections. The drug linezolid also showed 100% sensitivity.
