A wound is any physical injury involving a break in the skin, and exposed subcutaneous tissues provide a favorable substratum for a wide variety of microorganisms to contaminate and colonize. In this study a total of 870 plus samples were collected from patients visiting B & B hospital suspecting wound infection and then analyzed. The causative agents were isolated, identified by culture and biochemical tests and their susceptibility pattern to antibiotics were determined by using CLSI guidelines. Out of total samples, 476(44.8%) showed bacterial growth. Among growth cases 22.9% were mixed growths. Among all bacterial isolates, 12 species were identified of them, 70.6% were Gram-negative and 29.4% were Gram-positive. Among Gram-positive isolates, Staphylococcus. Aureus (74.2%) was most common followed by CoNS (8.6%), Non hemolytic Streptococci (8.6%), Enterococcus spp. (4.3%) and â -haemolytic Streptococci (4.3%). Among Gram-negative bacteria, the most common isolate was Pseudomonas aeruginosa (31.5%) followed by E.coli (24.8%), Acinetobacter spp. (14.6%), Enterobacter spp. (14.0%) and Klebsiella spp. (13.4%). Proteus spp. and Citrobacter spp. were less common. With regard to AST pattern, S. aureus was most susceptible to chloramphenicol and highly resistance to penicillin. Among them, 7.7% were MRSA. For other Gram-positive isolates as well, effective drug was found to be chloramphenicol. For P. aeruginosa, the most effective drug was imipenem (94.3%) followed by amikacin (63.2%). Likewise, for other Gram-negative bacteria most effective drug was imipenem followed by amikacin. Among the total P. aeruginosa isolates, 58.5% were found to be MDR. For all these P. aeruginosa isolates MIC on gentamycin and ciprofloxacin illustrate the simultaneous presence of ciprofloxacin resistance and reduced gentamycin susceptibility. These results indicated that antibiotic resistance in Gram-positive and Gram-negative bacteria were increasing in alarming trend that leads to the failure of treatment.DOI: http://dx.doi.org/njst.v15i2.12121Nepal Journal of Science and Technology Vol. 15, No.2 (2014) 91-96

Objectives: To determine the rate of soft tissues infection and perform antibiotic pattern susceptibility test of bacterial pathogens isolated from soft tissue infected patients visiting Shree Birendra Hospital, Kathmandu, Nepal. Methods:  A total of 380 wound specimens (open and closed) including pus and wound swabs were processed in the laboratory of Birendra Military Hospital, Chhauni from August to November 2018. The specimens were cultured on Blood Agar blood agar and Mac-Conkey agar and incubated at 37°C for 24 hrs. Antibiotic Susceptibility Test was performed by using modified Kirby-Bauer disc diffusion method. Thus, multidrug resistant (MDR) bacteria and methicillin resistant Staphylococcus aureus (MRSA) were differentiated. Results: Out of 380 bacterial isolates, 86(43.21%) were gram positive and 113(56.78%) were gram negative bacteria. Among all the gram-positive isolates 43(53.09%) were found to be MRSA. Similarly, 62(54.86%) were found to be MDR among the gram-negative bacteria. Gentamicin and Amikacin were found to be the most effective drug though the resistance pattern is not homogenous against all isolates. Conclusion: Antibiotic susceptibility pattern of all bacterial isolates showed that, Gentamycin, Amikacin, Levofloxacin, Piperacillin/ Tazobactam, Doxycycline was the effective drug for Gram-negative bacteria and Amikacin, Teicoplanin, Linezolid, Doxycycline, Gentamycin and Azithromycin was the most effective drug for Gram-positive organisms. Thus it can be concluded that these antibiotics may be used for the empirical treatment of soft tissues infection.

Background Neonatal sepsis is one of the major causes of morbidity and mortality among the newborns in the developing world. Objectives To determine the common bacterial isolates causing sepsis in neonatal intensive care unit and its antibiotic susceptibility pattern. Methods A one year discriptive prospective study was conducted in neonatal intensive care unit to analyse the results of blood culture and to look into the sensitivity of the commonly used antibiotics. Results The blood culture yield by conventional method was 44.13% with nosocomial sepsis accounting for 10.79%. 84.08% were culture proven early onset sepsis and 15.95% were late onset sepsis. Klebsiella infection was the commonest organism isolated in early, late and nosocomial sepsis but statistically not significant. Gram positive organisms were 39.36% in which Staphylococcus aureus was the leading microorganism followed by coagulase negative staphylococcus areus. Gram negative organisms were 60.64% amongst them Klebsiella was the most often encountered followed by Pseudomonas. The most common organism Klebsiella was 87.5% and 78.3% resistance to ampicillin and gentamycin respectively. Among gram negative isolates 87.5% and 77.2% were resistance to ampicillin and gentamycin respectively. Among gram positive isolates 58.5% and 31.5% resistance were noted to ampicillin and gentamycin respectively. Resistance to cefotaxim to gram negative and gram positive isolates were 87.34% and 59.35% respectively. Conclusion Klebsiella is most common organism which is almost resistance to first line antibiotics. Resistance to both gram negative and gram positive isolates among firstline antibiotics and even with cefotaxim is emerging and is a major concern in neonatal intensive care unit.

Wound infection is a major problem in hospitals in developing countries. Wound infection causes morbidity and prolonged hospital stay thus this prospective study was conducted for a period of seven months (January 2019 to July 2019). A total of 217 specimens (wound swabs and pus exudates) from wound infected patients in a Tertiary Care Hospital in Bangladesh. A retrospective study of the microbiological evaluation was done by cultural growth as well as Gram staining and biochemical examination to identify the bacterial isolates. Finally, the antimicrobial vulnerability testing was performed by Kirby-Bauer disc diffusion conventional method. A total of 295 samples were tested. Out of which 217 (73.5%) were found culture positive. E. coli was the most predominant gram-negative isolates whereas Staphylococcus aureus and Coagulase-negative Staphylococcus were the most commonly isolated gram-positive organisms. Antimicrobial sensitivity profile of bacterial isolates revealed imipenem, meropenem, amikacin, and nitrofurantoin to be the most effective antimicrobials against gram-negative isolates, whereas imipenem, meropenem, amikacin, nitrofurantoin, amoxiclav, and gentamicin were the most effective drugs against gram-positive isolates. The result of this examination contributes to the identification of basic causative microbes involved in wound infection and findings of antibiotic susceptibility patterns can be helpful for primary care physicians to optimize the treatment modalities, articulate policies for empiric antimicrobial therapy, and to minimize the rate of infection among wound infected patients.

Wound infections result in sepsis, limb loss, long hospital stays, higher costs, and are responsible for significant human mortality and morbidity worldwide. The present study was conducted to isolate and identify the causative organisms of wound infection, to determine the antibiotic susceptibility pattern of the isolates and to study the risk factors for wound infection. The study was conducted for six months in which pus specimens collected from 244 patients were processed to investigate etiological agents using standard technique. Disc susceptibility of bacterial agents were then determined. A total of 244 pus samples were collected and 147 (60.20%) samples showed growth. A total of 150 bacterial isolates were isolated; of which 118 (78.67%) were Gram positive and 32 (21.33%) were Gram negative bacteria. Staphylococcus aureus (72.00%) was most common followed by Escherichia coli (6.67%), Citrobacter freundii (5.34%), Staphylococcus epidermidis (4.00%), Pseudomonas aeruginosa (3.33%), Proteus mirabilis (2.00%), Enterococcus faecalis (1.33%), Acinetobacter spp. (1.33%), Klebsiella oxytoca (1.33%), Klebsiella pneumoniae (1.33%), Streptococcus pneumoniae (0.67%) and Streptococcus pyogenes (0.67%). The most effective antibiotic for Gram positive isolates was Gentamicin (77.97%). For Gram negative isolates (except Ps. aeruginosa), Amikacin (74.07%), for Ps. aeruginosa, Amikacin, Ciprofloxacin, Gentamicin and Ofloxacin each with the susceptibility of 80.00% and for Staph. aureus, Cloxacillin (79.63%) were the most effective antibiotics. Hence, the most common isolate in wound infection was Staph. aureus followed by E. coli. Therefore, routine microbiological analysis of the wound specimens and their antibiotic susceptibility testing is recommended that will guide clinician for treatment of wound infection.

The annual monitoring of the species composition of the causative agents of osteomyelitis, the identification of antibiotic-resistant strains, the study of the species composition of associations of microorganisms, their adhesive activity will prevent the spread of infection. Analyze the spectrum of the leading causative agents of osteomyelitis, their antibiotic sensitivity, and also the adhesive activity of the identified bacterial associations. A microbiological analysis of 2197 smears of adult patients with various etiological forms of osteomyelitis who were treated in the departments of the purulent center of the FSBI «NMRCTO» of the RF Ministry of Health in 2019. The spectrum of pathogenic microflora, sensitivity to standard antibacterial drugs used in the clinic was studied. The biofilm-forming ability of associations of microorganisms was investigated. According to the conducted microbiological monitoring for 2019, the microflora spectrum for osteomyelitis is diverse, the main pathogens are S. aureus, S. epidermidis, P. aeruginosa, K. pneumoniae, Enterococcus sp. A high percentage of isolation of microbial associations was noted, most often mix cultures of gram-positive and gram-negative bacteria. Bacterial associations: S. aureus + P. aeruginosa, S. aureus + S. marcescens, S. aureus + A. baumannii, S. epidermidis + E. cloacae - actively formed a biofilm on the surface of polystyrene plates, and the adhesive potential depended on interstrain relations in the composition of the formed biofilm. Among Gram-negative microflora, multiresistant strains prevail, among Gram-positive microflora - a high percentage of methicillin-resistant Staphylococci. When analyzing the antibiotic sensitivity of the isolated microorganisms, a high percentage of resistant strains is noted. So, with respect to enterobacteria, β-lactam antibiotics, drugs from the group of aminoglycosides, turned out to be ineffective. Among non-fermenting gram-negative bacteria, A. baumannii strains had multiple antimicrobial resistance. Among gram-positive microorganisms, a high percentage of isolation of methicillin-resistant staphylococci was noted. The specificity of the course of the disease and measures aimed at eliminating the pathogen depend on the species composition in the focus of infection. The study of the etiological structure of osteomyelitis, the monitoring of the antibiotic resistance of pathogens and their persistent potential, makes it possible to adopt sound tactics of conservative and surgical treatment.

In recent decades, the etiological structure of infectious complications in surgery has remained almost unchanged. The aim of this study is to identify the leading pathogens of odontogenic infectious and inflammatory diseases of the maxillofacial area in patients. Materials and methods. The study involved 137 patients with odontogenic infectious and inflammatory diseases of the maxillofacial area. The final species identification of microorganisms was performed according to the generally accepted method. Results. 117 clinical strains of microorganisms were isolated from patients and identified. It was found the most common causative agents of odontogenic infectious and inflammatory diseases of the maxillofacial area in patients were gram-positive cocci. It should be noted that the vast majority of isolates were members of the genus Staphylococcus. Gram-negative microorganisms were detected in patients much less frequently (31.6%) compared with gram-positive. In 5.1% of case, C. albicans acted as the dominant pathogen in the material taken from patients with purulent diseases. It was found out that during the development of the abscess, the microbiota were more diverse, but the percentage of pathogens differed significantly with the selection of S. aureus, A. baumannii and E. faecalis as the main ones. In turn, with the aggravation of the infectious process and the development of phlegmon and mediastinitis in patients, a decrease in the spectrum of microorganisms in the studied materials was observed, along with an increase in their percentages. Conclusions. The etiological structure of microbiota of odontogenic infectious-inflammatory diseases of the maxillofacial area is predominantly represented by opportunistic microorganisms of the genera Staphylococcus, Enterococcus, Acinetobacter and Pseudomonas. In general, gram-positive cocci and non-fermenting gram-negative bacteria are the dominant causative agents of odontogenic infectious-inflammatory diseases of the maxillofacial area in most surgical patients.

Recently, the world's problem has become in the spread of microbes and the extent of their impact on public health, especially the problem of urinary tract infections (UTIs). Therefore, the purpose of the study was to clarify the extent of infection of the urinary tract and the extent of development of these microbes in resistance to antibiotics (antibiotic susceptibility pattern). The pathogens are isolated from hospitals and private medical centers. In this study, two hundred twenty-five urine samples were collected from various sources, where 126 patients were infected with bacteria while 99 patients had no infection. In Gram-negative bacteria, the most common bacteria were E. coli (55.5%) followed by Klebsiella spp (23.0%), Proteus spp (7.14%), Pseudomonas spp (6.34%), and Acinetobacter spp (3.96%). In the Gram-positive bacteria Staphylococcus spp (2.38%) and Enterococcus spp (1.58%) were found. Antibiotic susceptibilities for Gram-negative and positive bacteria were investigated according to clinical laboratory standard institute(CLSI 2019). In Gram-negative bacteria, Amikcin, Impinem, and levofloxacin were sensitive. However, in Gram-positive bacteria, levofloxacin, ofloxacin, and linezolid were sensitive. At the same time, most of the remaining antibiotics are 100% resistant to pathogenic-bacterial isolates. This study showed bacteria that are isolated from urine which causing urinary tract infection and showed resistance to almost all antibiotics, so UTI is difficult to treat by common antibiotics.

Neonatal sepsis is one of the major causes of neonatal morbidity and mortality, particularly in developing countries. Epidemiology and surveillance of neonatal sepsis helps in implementation of rational empirical antibiotic strategy. A cross-sectional prospective study was conducted in the special care baby unit under department of Paediatrics and Neonatology, BIRDEM General Hospital during the period of November 2008 to September 2009 to determine the pattern of bacterial agents causing neonatal sepsis and their susceptibility pattern to various antimicrobial agents. Blood cultures were performed on admitted newborn babies (0-28 days) to rule out sepsis. Antimicrobial susceptibility testing was done for all blood culture isolates according to the criteria of the National Committee for Clinical Laboratory Standards by disk diffusion method. Out of 720 screened blood cultures, 64 (8.9%) reported as positive and the gram positive and gram negative bacteria accounted for 6 (9.4%) and 58 (90.6%) respectively. The most common gram positive organisms were Staphylococcus aureus (6.3%) and Enterococci (3.1%) & gram negative organisms were Klebsiella pneumoniae (37.5%), Serratia (25%), Pseudomonas aeruginosa (10.9%), Citrobacter (10.9%) and Acinetobacter (6.3%). The susceptibilities were remarkably low to Ampicillin (3.12 %) & Cefotaxim (10.9%) for both gram positive & gram negative isolates. Gram positive group had susceptibilities of 66.7% to Ciprofloxacin and Imipenem, 83.3% to Gentamicin, & 100% to Amikacin & Vancomycin. Gram negative isolates showed higher sensitivities to Imipenem (94.8%), Ciprofloxacin (89.7%), Amikacin (72.4%) respectively. Gram-negative bacteria showed high level of resistance to commonly used antibiotics (Ampicillin, Ceftazidim and Cefotaxim). Gentamicin, Amikacin, Imipenem and Ciprofloxacin were the most effective drugs compared to others. Routine bacterial surveillance and their sensitivity patterns must be an essential component of neonatal care. CBMJ 2014 January: Vol. 03 No. 01 P: 35-40
