This work aimed to study the bacteriological and antibiotics susceptibility profile of bacteria involved in effusion fluid infections in paediatrics in order to improve the choice of probabilistic antibiotics therapy. Methods: A cross-sectional, descriptive study was used in children aged 0 to 15 years from 2017 to 2020 at the Charles De Gaulle Pediatric University Hospital Center (CHUP-CDG) in Ouagadougou. Classical bacteriology methods such as macroscopy, Gram staining, identification galleries and antibiotics susceptibility testing were used. Results: Of 231 samples, 64 bacteria were isolated. The most common bacterial strains of pleural fluid were Staphylococcus aureus (25%) and 40% for Enterobacteriaceae. Of the peritoneal fluid, 77% were Enterobacteriaceae with 57% Escherichia coli;and from joint fluid, 33% were S. aureus and 22% for P. aeruginosa. The overall susceptibility profile showed 29% extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL), 10% methicillin-resistant S. aureus (MRSA), and 8% carbapenemases. Conclusion: Bacteriological profile is characterized by ESBL-producing Enterobacteriaceae and MRSA. The most active antibiotics were macrolides, aminoglycosides, and cefoxitin (methicillin) for Gram-positive cocci, carbapenems, and aminoglycosides for Gram-negative bacilli. Then, the monitoring of antibiotics resistance must be permanent.展开更多

In Tanzania, neonatal sepsis is the third leading cause of neonatal death, accounting for 25% of all deaths. The rising global threat of antimicrobial resistance and the rising burden of neonatal death due to neonatal sepsis have been of great concern and have delayed progress toward reaching SDG goal 3.2 by 2030. This study aims to determine the bacteriological profile, antibiotic susceptibility patterns, and predictors of bacteremia among neonates with clinical sepsis at KCMC Hospital in Northern Tanzania. Methodology: This study had a cross-sectional design conducted at KCMC Hospital, Northern Tanzania. The study population was neonates admitted to the neonatal unit at KCMC Hospital. Data were collected using questionnaires and blood cultures from neonates. Frequencies and proportions were used to summarize categorical variables, while continuous variables were summarized using mean and standard deviation. The frequencies and proportions of bacteria isolated and the antimicrobial susceptibility results were analyzed and compared using Pearson’s chi-square test and Fisher’s exact test where applicable. Modified Poisson regression model was used to determine factors associated with positive blood culture. Results: Out of 411 neonates with a clinical diagnosis of neonatal sepsis, 175 (42.9%) had positive blood cultures. Gram-positive bacteria were most frequently isolated at 52.3%, and gram-negative bacteria were 47.7%. Coagulase-negative Staphylococcus (30.7%) and Staphylococcus aureus (19.9%) were the predominant gram-positive isolates. Gram-negative isolates were Klebsiella spp 47 (26.7%), E. coli 10 (5.7%), and Citrobacter spp 10 (5.1%). The gram-positive isolates were sensitive to vancomycin, piperacillin/tazobactam, and ceftazidime, whereas the gram-negative were sensitive to amikacin, meropenem, and vancomycin.展开更多

The aim of this study is to establish the bacteriological and antimicrobial susceptibility profile of cervico-facial cellulitis at the Regional Teaching Hospital (RTH) of Ouahigouya, in order to guide practitioners in the development of effective probabilistic antibiotic therapy protocols. Subjects and Methods: This was a transversal descriptive study with prospective data collection from July 1 to December 31, 2021 at the RTH of Ouahigouya. All cases of suppurative cervicofacial cellulitis that had been the subject of pyoculture were retained. Results: A total of 63 patients were chosen including 41 men, with 40.91 years as the average age and the sex ratio was 1.86. In 90.48% of cases, the front door was dental. All patients took antibiotics before their admission. Pus culture was positive in 34/63 subjects (53.97%) and showed monomicrobial infection. The isolates were Gram-negative bacilli for 20.59% and Gram-positive cocci for 79.41%. These isolates were all resistant to certain beta-lactams (such as amoxicillin, amoxicillin + clavulanic acid). However, some isolates were susceptible to cefoxitin, ceftazidime and ceftriaxone. All isolates were sensitive to amikacin for aminoglycosides. As for macrolides, erythromycin had excellent activity (100%) against Gram-positive cocci. Indeed, some isolates were susceptible and others resistant to ciprofloxacin for quinolones. Conclusion: Bacteriological profile and antimicrobial susceptibility knowledge of cervicofacial cellulitis may propose an effective probabilistic antibiotic therapy protocol.展开更多

In most instances the infecting organisms are normal inhabitants of the lumen of appendix. Surgery allows easy microbiological sampling. Aspiration of fluid or pus in a syringe is preferred. Swabs are less suitable and only to be used when sampling with a syringe is not feasible. Antimicrobial susceptibility testing of the isolated bacteria and particularly of the anaer- obes can be important to adjust therapy in case of the presence of multi resistant bacteria. Objective: The aim of the study was to determine the bacteriological profile of acute appendicitis in children. Materials and Methods: Study design is a prospective descriptive study including children hospitalized for acute appendicitis. Tissue samples (a speci- men of the appendix), peritoneal fluid swab from the appendicial fossa and the peritoneal exudates (if exists) obtained at surgery from 54 children with suspected acute appendicitis operated at the pediatric surgery unit at the Maternity and Child Teaching Hospital in Al-Qadisiya province from the period 1st of June 2007 to the end of May 2011, were exam- ined histologically and by culture for aerobic and anaerobic bacteria. Results: Out of these, 39 boys (72.2%) and 15 (27.7% girls). Their age ranged between (1.8 - 13) years, with a mean of 6.9 years. Of the all patients studied 34 pre- sented with suppurative and phlegmnous appendicitis, 8 with gangrenous appendicitis, 6 with septic complications of appendicitis and 6 had normal appendices. Only 80 of the 108 swabs taken yielded a positive culture (74.07%). Con- clusion: Although in our study no antibiotic regime was changed on the basis of a positive culture swab and the perito- neal culture swabs do not improve immediate postoperative therapy based on surgical impression and rapid histological reporting, however, the routine use of peritoneal culture swabs may be of value in identifying patients requiring outpa- tient follow-up.展开更多
