Identification of organisms and effective antibiotic therapy is an important component of treatment of diabetic foot infections. This study was undertaken to determine the organisms associated with diabetic foot infection (DFI) and their antibiotic sensitivity pattern. A total of 75 patients having type 2 diabetes mellitus with Wagner's grade 1-5 foot ulcers attending BIRDEM hospital were included in the study. Specimens were processed for aerobic culture. The bacteriological isolation and antimicrobial sensitivity tests of the isolates were done by standard microbiological methods. Gram negative bacilli were tested for extended spectrum â lactamase (ESBL) production by double disc diffusion method. Culture was positive in 92% of the cases which yielded 135 pathogens. Of the positive culture, 75.3% had multiple organisms. Polymicrobial infection was more in higher grade of foot ulcers. Gram negative organisms were most frequently isolated (80%) bacteria. Pseudomonas (48%) and Proteus sp.(33%) was the most common Gram negative organisms isolated. Staphylococcus aureus was the most commonly isolated gram positive organism (21.3%). ESBL production was noted in 31.5% Gram negative bacilli and methicillin resistance was noted in 43.8% of Staphylococcus aureus. Most of the Gram negative bacilli were resistant to various classes of antibiotics. Imepenem was the most effective agent against Gram negative organisms, while vancomycin was for staphylococcus. The present study has shown that infection with multidrug resistant Gram negative bacilli is the most common cause of DFI in BIRDEM hospital. Ibrahim Med. Coll.

Abstract Background Diabetic foot ulcer infection cause great morbidity and mortality among diabetic patients and is a major cause of lower extremity amputation worldwide. This study aimed to determine the profile of aerobic bacteria and their antibiotic sensitivity patterns in diabetic foot infections (DFI) among different Wagner's grades. Methods This study was conducted during December 2017 - March 2018 in a Diabetic Center, Sudan. A total of 152 diabetic patients with different grades of foot ulcers were randomly enrolled in the study. The patients were grouped using Wagner's classification. Tissue biopsies and deep swabs were collected from the ulcers for aerobic cultures. The cultured isolates were identified using phenotypic and biochemical properties and their sensitivity to commonly used antibiotics, Colistin, Aikacin, Ciprofloxacin, Augmentin, Ceftazideme, Gentamicin, Clindamycin, Ceftriaxone Meropenum. Cotrimoxazole, Erythomycin, Oxacillin and Vancomycin. Fusidic acid, Imepenem, and Piperacillin was tested using the Kirby Bauer disk diffusion method. Results The mean age of the patients was 54.31 (SD ± 12.1) years, male to female ratio of 8: 1. The mean duration of diabetes was 14 (SD ± 8) years. The ulcers varied in duration from 1 day to 10 years. of 152 samples 181 aerobic bacteria were isolated. Cultures yielded 1-3 isolate per culture. The maximum number was isolated from grade 3 group followed by long standing ulcer LSU group 50.8% and 28% respectively. Polymicrobial infection was higher in LSU (30.4%). The isolates were mostly Gram-negative bacteria. The most frequent were proteus spp. (35.3%), S. aureus MRSA 14.4% and Coliform 12.2% respectively. The most common isolates in grade 3 were P. Mirablis, Staphylococcus and Coliform and in long standing ulcers were P. Mirablis, S. aureus MRSA and Coagulase negative staphylococcus respectively. Conclusion Gram-negative bacteria were more prevalent and the most frequent pathogens were Proteus spp. The most common polymicrobial infections were due to P. mirablis with; P. aerginosa, S. MRSA and Coliform respectively . Gram negative rods were sensitive to Amikacin, (80.6) %) while the highest sensitivity of Gram positive was to Imepnem (85%). Most of the isolates were sensitive to Meropenem. No significant relation between Wagner grades and neuropathy was detected.

Introduction: In the present study, we sought to identify the bacterial organisms associated with diabetic foot infections (DFIs) and their antibiotic sensitivity profiles. Methodology: We retrospectively reviewed the records of wound cultures collected from diabetic patients with foot infections between May 2005 and July 2010. Results: We identified a total of 298 culture specimens (165 [55%] wound swab, 108 [36%] tissue samples, and 25 [9%] bone samples) from 107 patients (74 [69%] males and 33 [31%] females, mean age 62 ± 13 yr) with a DFI. Among all cultures 83.5% (223/267) were monomicrobial and 16.4% (44/267) were polymicrobial. Gram-negative bacterial isolates (n = 191; 61.3%) significantly outnumbered Gram-positive isolates (n = 121; 38.7%). The most frequently isolated bacteria were Pseudomonas species (29.8%), Staphylococcus aureus (16.7%), Enterococcus species (11.5%), Escherichia coli (7.1%), and Enterobacter species (7.1%), respectively. While 13.2% of the Gram-negative isolates were inducible beta-lactamase positive, 44.2% of Staphylococcus aureus isolates were methicillin resistant. Conclusions: Our results support the recent view that Gram-negative organisms, depending on the geographical location, may predominate in DFIs.

Introduction:Diabetic foot ulcer and infections are one of the major complications in diabetic patients leading to frequent hospitalization and increased mortality. Knowledge about the microbes that cause infections will be helpful for providing appropriate antimicrobial therapy. Aim:To evaluate the bacteriological profile of patients with diabetic foot ulcers and their antibiotic susceptibility pattern. Methodology:A cross-sectional study was carried out for a period of eight months in the Department of surgery in patients with diabetic foot ulcer at a tertiary care teaching hospital. Patient data relevant to the study were collected using a standard data collection form designed as per the need of the study. Details of the organisms isolated and susceptibility pattern were collected from microbiology department. Results:A total of 122 pathogens were identified from 71 patients with male (63.38%) predominance over females (36.61%). Out of the 71 patients, 38 (53.52%) patients had monomicrobial infections and 33 (46.47%) patients had polymicrobial infections. Of the total 122 organisms, 79(64.75%) organisms were found to be gram negative organisms and 43(35.24%) were gram positive. Pseudomonas aeruginosa found in 22 (18.03%) patients was the predominant pathogen isolated followed by Klebsiella pneumonia found in 18 (14.75%) patients. The gram-positive organisms isolated showed maximum susceptibility towards antibiotics Teicoplanin and Linezolid while the gram-negative organisms showed susceptibility to Imipenem, Meropenem, and Piperacillin/Tazobactum combination. Conclusion:The study showed a preponderance of gram-negative bacilli among the isolates from the diabetic foot ulcers. It is recommended that antimicrobial sensitivity testing is necessary for initiating appropriate antibiotic regimen which will help to reduce the drug resistance and minimize the healthcare costs.

Background: Sepsis is the second major cause of mortality among neonates. Present study was done to identify the common organisms which cause early and late onset neonatal sepsis in neonates admitted in our department and their antibiotic sensitivity patterns.Methods: All neonates weighing more than 1500 gms and born to mothers with pre-existing infection, admitted to neonatal intensive care unit for suspected neonatal sepsis were included in the present study. They underwent blood culture and antibiotic sensitivity profiling.Results: 210 newborns were admitted to the NICU of our department for suspected neonatal sepsis. Longer duration of rupture of membranes was found to be significantly associated with growth of organisms. Amongst the cases with gram positive organisms, most were due to Coagulase-negative staphylococci (CoNS) (n=25), followed by Staphylococcus aureus (n=14), and, Enterococcus (n=4). Gram negative organisms isolated constituted 17 organisms. Amongst the cases with gram negative organisms, mostly were due to Klebsiella (n=10), followed by Pseudomonas (n=5) and E. coli (n=2). The most common organism causing early onset sepsis was CoNS, while Staphylococcus aureus was the most common organism causing late onset sepsis. CoNS was fully sensitive to Vancomycin and Amikacin. Staphylococcus aureus was fully sensitive to Amikacin, α-hemolytic. Streptococcus were sensitive to Amikacin, Vancomycin and Piperacillin and Tazobactum and Enterococcus was sensitive to Amikacin and Vancomycin.Conclusions: Antimicrobial surveillance of neonatal septicaemia is required to know the antibiotic sensitivity pattern and thus to formulate policies on use of antibiotics and to know the changing spectrum of antimicrobial sensitivity patterns.

We sought to define the type and antibiotic sensitivity response of pathogens isolated from diabetic foot ulcers based on ulcer location and Wagner classification. This retrospective analysis was done among 126 patients between 40 and 70 years of age at the Prince Sultan Military Medical City, Riyadh, Saudi Arabia, using the swab culture method for microbiological assessment. Data on demographic variables, ulcer sites (location), and depth of ulcer (Wagner classification) were also collected. A total of 134 pathogens were isolated from 126 patients. The most common gram-negative pathogen identified was Pseudomonas aeruginosa (15.6%), followed by Klebsiella spp (6.7%). The most common gram-positive pathogen was Staphylococcus aureus (35%), followed by Streptococcus (8.9%). The most widely accepted antibiotic to which the gram-negative bacteria were sensitive was gentamycin (20.1%), followed by ciprofloxacin (19%). The most routinely used antibiotic in the treatment of the gram-positive bacteria was erythromycin (16%), with trimethoprim-sulfamethoxazole (14.1%) being the next most effective. In conclusion, Pseudomonas aeruginosa, Klebsiella spp, Staphylococcus aureus, and Streptococcus were the most common causes of diabetic foot infections. However, the frequency of encountered pathogens and respective sensitivity to antibiotic therapy may be influenced by the location site and severity of the ulceration.
