Aim: To determine spectrum of bacteria infecting burn wound and its antibiotic susceptibility at Benue State University Teaching Hospital (BSUTH). Study Design: A one year prospective study of the microbial profile in burn wound infection at BSUTH, Makurdi. Methodology: All patients admitted from August 2018 to July 2019 with burn wound who had wound swab microscopy culture and sensitivity (MCS) after thorough cleaning of the wound were included in the study. Data collected included the Age, Sex, Occupation, Total Body Surface Area (TBSA) of burn, injuring agent, type of burn, bacteria cultured from the wound, antibiotic susceptibility, number of days of admission and outcome of treatment. Results: Out of the 63 patients admitted, flame was the predominant injuring agent seen in 54 (85.7%) patients. The age group 21 – 30 years was the most affected, 27 constituting 42.9%. Burn wound infection occurred in 25(39.7%) patients from whom 33 bacterial isolates were recovered. Gram negative organisms Pseudomonas species and Proteus species were the commonest bacteria isolated constituting 21.21% each. Other isolates were Staphylococcus aurous 36.36%, Escherichia coli 15.15%, Klebsiella species and Staphylococcus saprophyticus (each 3.03%,). There was multiple bacteria colonization of wounds and antibiotics resistance. There was no gender difference in the burn wound infection, P =0.7819. Conclusion: The sensitivity pattern showed many of the bacteria to be resistant to commonly administered antibiotics but sensitivity patterns got are important for empirical antibiotics prescription when patients come with glaring sepsis and are waiting for wound swab microscopy culture and sensitivity. Studying the microbial profile with antibiotic resistance pattern in burn’s wound infection should be a continuous process in all burn units/departments. This will help to formulate and modify at regular intervals, a hospital/departmental antibiotic policy according to the present microbial pattern in the respective burns unit.

Introduction:Klebsiella pneumoniae are common causative agents of various infections and are of great concern for developing resistance against commonly prescribed antibiotics. This study gives an account of isolation of K. pneumoniae from various clinical specimens and their antimicrobial susceptibility, in a tertiary care hospital of Bangladesh. Materials and Methods: Various clinical specimens like urine, wound swab, sputum, blood and endotracheal aspirates were collected and processed for isolation of K. pneumoniae followed by their antimicrobial susceptibility testing. Results: Among the 316 samples that yielded culture positivity, K. pneumoniae were identified as second most common organism. The highest yield of K. pneumoniae (37.33%) were observed from wound swab followed by sputum (26.67%). Most of the isolates were resistant to sulphamethoxazole-trimethoprim (90.67%) and ceftriaxone (90.67%) followed by cefotaxime (89.33%), ceftazidime (89.33%) and cefuroxime (89.33%). The most sensitive antibiotic for the isolates was tigecycline. Conclusion: Isolated K. pneumoniae showed resistance to commonly prescribed antibiotics, which is very alarming and showing the importance on continuous monitoring and strict antimicrobial policy.

Aspergillus niger, an opportunistic filamentous fungus, was identified as the cause of chronic unilateral otomycosis in a 55-year old, immunocompromised man who had been unresponsive to a variety of treatment regimens. The patient presented with intermittent otalgia and otorrhea and with a perforation of his left tympanic membrane. A niger was identified in a culture specimen obtained from the patient's left ear canal. In immunocompromised patients, it is important that the treatment of otomycosis be prompt and vigorous, to minimize the likelihood of hearing loss and invasive temporal bone infection.

Background.In studies of the association between antibiotic-resistant infection and mortality, the importance of controlling for the underlying severity of illness is well recognized. However, it is unclear when the severity of illness should be assessed. Controlling for severity of illness on the day the culture specimen is obtained may underestimate the true association between resistance and mortality.Objective.TO assess the impact of calculating the Acute Physiology and Chronic Health Evaluation (APACHE) II score at different time points on the association between antimicrobial resistance and mortality.Methods.We used an existing data set from a study that investigated the association between fluoroquinolone resistance and mortality. The APACHE II score was calculated at 3 time points: the day the culture specimen was obtained, 1 day before the culture specimen was obtained, and 2 days before the culture specimen was obtained. Separate multivariable models were constructed using the 3 different APACHE II scores. These models were compared qualitatively.Results.Of 91 total subjects, 51 were infected with a fluoroquinolone-resistant strain and 40 with a fluoroquinolone-susceptible strain. The median APACHE II score for all subjects was 13 (95% confidence interval [CI], 11-15) when calculated on the day the culture specimen was obtained, 12 (95% CI, 11-13) when calculated 1 day before, and 11 (95% CI, 10-13) when calculated 2 days before the culture specimen was obtained. Of 91 subjects, 12 (13.2%) died. The 3 multivariable models (each with the APACHE II score calculated on a different day) were not substantively different; the adjusted odds ratio for the association between fluoroquinolone-resistant infection and mortality varied only from 1.38 to 1.65 in the 3 models.Conclusions.APACHE II scores calculated at different time points relative to obtainment of the culture specimen did not differ substantively. Furthermore, when the adjusted association between fluoroquinolone resistance and mortality was assessed, there were no substantive differences across multivariable models that incorporated APACHE II scores calculated at different time points.

Susceptibility Patterns

In Nepal, little is known about the microbiological profile of wound infections in children and their antimicrobial susceptibility patterns. Total of 450 pus/wound swab samples collected were cultured using standard microbiological techniques and the colonies grown were identified with the help of biochemical tests. The antimicrobial susceptibility testing was performed by Kirby-Bauer disc diffusion technique. Methicillin-resistantStaphylococcus aureusisolates were detected by using cefoxitin disc and confirmed by determining minimum inhibitory concentrations (MIC) of oxacillin. 264 (59%) samples were culture positive. The highest incidence of bacterial infections was noted in the age group of less than 1 year (76%). Out of 264 growth positive samples, Gram-positive bacteria were isolated from 162 (61%) samples and Gram-negative bacteria were found in 102 (39%) samples.Staphylococcus aureus(99%) was the predominant Gram-positive bacteria isolated andPseudomonas aeruginosa(44%) was predominant Gram-negative bacteria. About 19% ofS. aureusisolates were found to be methicillin-resistant MIC of oxacillin ranging from 4 μg/mL to 128 μg/mL. Among the children of Nepal, those of age less than 1 year were at higher risk of wound infections by bacteria.Staphylococcus aureusfollowed byPseudomonas aeruginosawere the most common bacteria causing wound infections in children.

Lactamase Gene

The emergence of AmpC (pAmpC) β-lactamases conferring resistance to the third-generation cephalosporins has become a major clinical concern worldwide. In this study, we aimed to evaluate the expression of AmpC β-lactamase encoding gene among the pathogenic Gram-positive and Gram-negative resistant bacteria screened from clinical samples of Egyptian patients enrolled into El-Qasr El-Ainy Tertiary Hospital in Cairo, Egypt. A total of 153 bacterial isolates of the species Pseudomonas aeruginosa, Klebsiella pneumoniae, and Enterococcus faecium were isolated from patients diagnosed with urinary tract infection (UTI), respiratory tract infection (RTI), and wound infections. The total number of E. faecium isolates was 53, comprising 29 urine isolates, 5 sputum isolates, and 19 wound swab isolates, whereas the total number of P. aeruginosa isolates was 49, comprising 27 urine isolates, 7 sputum isolates, and 15 wound swab isolates, and that of the K. pneumoniae isolates was 51, comprising 20 urine isolates, 25 sputum isolates, and 6 wound swab isolates. Our results indicated that there is no significant difference in the expression of AmpC β-lactamase gene among the tested bacterial species with respect to the type of infection and/or clinical specimen. However, the expression patterns of AmpC β-lactamase gene markedly differed according to the antibacterial resistance characteristics of the tested isolates.

Background: Antimicrobial sensitivity pattern from clinical isolates can reveal important information that can help in drafting the hospital antibiotic policy as well as help improve prescribing patterns and patient outcome in a particular region.Methods: Data from the results of the antimicrobial sensitivity pattern of clinical isolates of the patients between 1stJuly and 31st December 2018 were collected on a pre-designed and pre tested case study form and analysed with the help of descriptive statistics.Results: A total of 75 blood culture reports were obtained which showed 58 gram positive cultures. Further 46 of the gram positive samples were positive for Coagulase negative Staphylococcus. A total of 305 urine samples were obtained for culture which showed gram negative cultures. Paediatric and medicine wards were the common yielding sites. A total of 242 pus reports were obtained which showed 47 gram positive cultures. A total of 154 wound swab samples were obtained which showed 47 gram positive cultures. For pus and wound swab samples, surgery wards were the common yielding sites. Common gram negative organisms seen were Klebsiella sp., E. coli, Citrobacter sp., Pseudomonas, Proteus and Enterobacter. Gram positive organisms were commonly resistant to Erythromycin, orally active Penicillins, Vancomycin and Teicoplanin and gram negative organisms were commonly resistant to Cephalosporins, Aminoglycosides, Colistin, Fluroquinolones and Meropenem.Conclusions: This study showed that over six months samples of body pus, wound swab, blood culture and urine showed high levels of resistance to commonly used antibiotics. This would provide an outline for development of an effective hospital Infection Control Policy.

A wound gets infected when the organism gets invaded through the breached skin, proliferated and production of various enzymes, toxins, etc. In order to treat the wound infection, antibiotic susceptibility pattern of organism should be determined before the prescription of the medicine. The present study was conducted from September 2017 to March 2018 with an aim to determine antibiotic susceptibility pattern of Staphylococcus aureus identified from the pus/wound swab among the patients visiting the International Friendship Children's Hospital, Kathmandu, Nepal. Total 270 sample were processed, isolated and identified using standard microbiological procedure and biochemical test. Antibiotic susceptibility test was carried out by using Modified Kirby Bauer's Disc Diffusion Method. Out of total sample, 51.48% (139) showed growth. The growth distribution was found to be high in out-patient department 84.9% (118) than in-patient department 15.1% (21). Among 139 positive growth, 83.5% were gram positive and 16.5% were gram negative. All together 12 different organisms were identified, among which S. aureus was found to be predominant organism 105 (75.5%). S. aureus was found to be sensitive towards Linezolid followed by Doxycycline whereas it was found resistant towards Ciprofloxacin. Among S. aureus identified, 50% were Multidrug resistant (MDR) S. aureus and 55% were Methicillin resistance S. aureus (MRSA). MRSA was found to be sensitive towards Linezolid followed by Doxycycline and resistant towards Ciprofloxacin. The association between MDR and MRSA was found positively significant (i.e. p-value = 0.000). All strains of S. aureus were found to be sensitive towards Vancomycin.  22.86% were double disk diffusion test (D-test) positive. The prevalence of D-test was found to be high in MRSA (75%). The relationship between D-test and MRSA was found to be significantly correlated with each other (r = 0.39). Linezolid, Chloramphenicol, Vancomycin and Doxycycline is a drug of a choice for both S. aureus and MRSA infection.
