Abstract Background: Enterobacteriaceae are one of the most predominant pathogen in surgical site infections. In recent years we oberved increase in resistance among bacteria from surgical site infections. The aim of this study was to evaluate antimicrobial suceptibility pattern of Enterobacteriaceae isolates from surgical site infections, the biofilm formation and the production of OXA-48 carbapenemase.Methods: A total of 41 Enterobacteriaceae (19 Escherchia coli, 8 Enterobacter sp., 9 Citrobacter sp., and 5 Serratia sp. ) clinical isolates were collected from patients with SSI in Hôpital Saint Joseph (Kinshasa) for diagnostic purposes. The pus samples were cultured and the antibiotic susceptibility profile of the isolates were determined by disk-diffusion method following Clinical and Laboratory Standards Institute 2012 recommendations. OXA-48-producing Enterobacteriaceae were detected using ChromaticTM OXA-48 chromogenic medium. Crystal Violet Staining Method was used to assess the ability of bacteria strains to form a biofilm. Results: All Enterobacteriacea isolates studied were biofilm producers and highly resistant to the majority of antibiotics tested. E. coli, Enterobacter sp., Citrobacter sp., and Serratia sp. were 100 % resistant cefotaxime, imipenem, and amoxicillin-clavulanic acid, and ampicillin. Serratia sp. isolates were 100% and 80% sensitive to norfloxacine and amikacine respectively. There was relationship between antibiotic resistance and biofilm production. E. coli, Enterobacter sp., and Citrobacter sp. strains were all OXA-48 producers.Conclusion: The results of the present study demonstrate the emergence of multidrug resistant organisms, the correlation between antibiotic resistance- biofilm formation and OXA-48 production. These results suggest the implementation of antimicrobial resistance survey programm in order to prevent and combat the spread of multidrug resistant organisms in hospital and community in Democratic Republic of Congo.

Abstract Background and aims: Infected foot ulcer is one of the most feared complications of diabetes mellitus. Staphylococcus aureus is the most frequently isolated pathogen in diabetic foot infections. The aim of this study was to evaluate the prevalence of S. aureus strains involved in producing foot infections in diabetic patients and the antibiotic resistance pattern of these strains. Material and methods: The study included 33 S. aureus strains isolated from 55 diabetic foot ulcers. The subjects were selected from the 2465 patients with diabetes mellitus hospitalized in the Timişoara Diabetes Clinic, between 2011 and 2013. Germs’ identification relied on cultural and biochemical characteristics. Final identification and antimicrobial testing were performed using the Vitek 2 (Bio Merieux France) automatic analyzer. Results: All the 55 samples collected from diabetic foot ulcers were positive. We isolated 64 bacterial strains (some samples were positive for 2 microorganisms). The most frequently isolated germ was S. aureus, in 33 samples (51.56%). All these S. aureus strains showed resistance to benzylpenicillin, while only 33.33% were methicillin-resistant (MRSA). Conclusions: The most frequently isolated germ in the wound secretions from diabetic foot ulcers was S. aureus. The highest percentage of antimicrobial resistance was recorded to benzylpenicillin and erythromycin.

Foot infections are the main disabling complication in patients with diabetes mellitus. These infections can lead to lower-limb amputation, increasing mortality and decreasing the quality of life. Biofilm formation is an important pathophysiology step in diabetic foot ulcers (DFU)—it plays a main role in the disease progression and chronicity of the lesion, the development of antibiotic resistance, and makes wound healing difficult to treat. The main problem is the difficulty in distinguishing between infection and colonization in DFU. The bacteria present in DFU are organized into functionally equivalent pathogroups that allow for close interactions between the bacteria within the biofilm. Consequently, some bacterial species that alone would be considered non-pathogenic, or incapable of maintaining a chronic infection, could co-aggregate symbiotically in a pathogenic biofilm and act synergistically to cause a chronic infection. In this review, we discuss current knowledge on biofilm formation, its presence in DFU, how the diabetic environment affects biofilm formation and its regulation, and the clinical implications.

Gram Positive Cocci

Diabetic foot infections are a common and serious problem for all health systems worldwide. The aim of this study was to examine the resistance to antibiotics of microorganisms isolated from infected soft tissues of diabetic foot ulcers, using tissue cultures. We included 113 consecutive patients (70 men, 43 women) with a mean age of 66.4 ± 11.2 years and a mean diabetes duration of 14.4 ± 7.6 years presenting with diabetic foot soft tissue infections. Generally, no high antibiotic resistance was observed. Piperacillin-tazobactam exhibited the lowest resistance in Pseudomonas, as well as in the other Gram-negative pathogens. In methicillin-resistant Staphylococcus aureus isolates, there was no resistance to anti-Staphylococcus agents. Of note, clindamycin, erythromycin, and amoxycillin/clavulanic acid exhibited high resistance in Gram-positive cocci. These results suggest that antibiotic resistance in infected diabetic foot ulcers in our area is not high and they are anticipated to prove potentially useful in the initial choice of antibiotic regimen.

Objective: To assess the knowledge, attitudes and practices declared among general practitioners (GPs) concerning the use of antibiotics for the treatment of ARI in children under 5 years in Lubumbashi. Methods: A cross-sectional survey was conducted to assess the level of knowledge, attitude and practices concerning antibiotic prescribing among 67 GPs working in the pediatric setting in various health structures in Lubumbashi city, in the Democratic Republic of Congo. Data were collected from April 1st to June 30th, 2020. Results: GPs had limited knowledge about antibiotic prescriptions (mean of 46% correct answers to 8 questions). Although they are generally concerned about antibiotic resistance (mean ± SD = 0.50 ± 0.68), and are unwilling to submit to pressure to prescribe antibiotics to meet patient demands and expectations (mean ± SD = –1.78 ± 0.31) and the requirements to prescribe antibiotics for fear of losing patients (mean ± SD = –1.67 ± 0.47), there was a lack of motivation to change prescribing practices (mean ± SD = −0.37 ± 0.94) and strong agreement that they themselves should take responsibility for tackling antibiotic resistance (mean ± SD = 1.24 ± 0.74). Multiple linear regression results showed that higher knowledge scores were associated with less avoidance of responsibility when prescribing antibiotics (β = 0.919; p = 0.000). Conclusion: To curb the over-prescription of antibiotics, it is not enough to improve knowledge in itself. The lack of motivation of physicians to change must be addressed through a systematic approach. These data show the need for interventions that support the rational prescribing of antibiotics.
