Cutibacterium acnes est un germe de la flore commensale de la peau, responsable d'infections associées aux prothèses surtout au niveau de l'épaule. Il est extrêmement rare dans les arthrites septiques des membres inférieurs. Ce travail rapporte un cas d'arthrite septique du genou à C. acnes. Le diagnostic a été établi à partir des cultures d'enrichissement prolongées. Le but de ce travail est de mettre en exergue l'importance d'enrichir le liquide articulaire sur les flacons d'hémoculture, et de prolonger les cultures pendant au moins deux semaines afin d'augmenter la sensibilité diagnostique pour les germes atypiques, notamment C. acnes. Cutibacterium acnes is a germ of the commensal flora of the skin, responsible for infections associated with prostheses, especially at the shoulder level. It is extremely rare in septic arthritis of the lower limbs. This work reports a case of septic arthritis of the knee caused by C. acnes. The diagnosis was established from prolonged enrichment cultures. The aim of this work is to highlight the importance of enriching the joint fluid on blood culture bottles, and of extending the cultures for at least two weeks in order to increase diagnostic sensitivity for atypical germs, particularly C. acnes.

Introduction. Peritonitis is characterized by acute inflammation of the peritoneum, often resulting from digestive organ perforation or intra-abdominal septic focus. It may be of either infectious or non-infectious origin. The bacteria involved are those of the digestive flora ( Enterobacteriaceae and anaerobes), while Gram-positive cocci and yeasts can be isolated in nosocomial infections. Our study aims to isolate and identify the germs involved in community-acquired peritonitis in order to assess their susceptibility to the antibiotics available in our country. Methods. This is a retrospective study of the bacteriological profile of community peritonitis in Rabat Morocco. A total of 150 adult patients with peritonitis were admitted and samples were collected intraoperatively for bacteriological examination between 1 July 2022 and 30 April 2023. Results. Among the 150 patients, 101 (67.8%) were males and 49 (32.2%) were females, with a sex ratio (M/F) of 2 : 1. The mean age of the patients was 40.5 years±20.12. The distribution of bacteria was dominated by Escherichia coli (44%). Overall, 70% of E. coli isolated exhibited resistance to ampicillin, whereas no resistance to ampicillin has been reported for Enterococcus . Discussion. In the present study, we were interested in the bacteriological profile of community peritonitis in order to adapt the antibiotic therapy to our bacterial ecology. Our findings indicate a concerning trend of increasing resistance among E. coli to the commonly used amoxicillin/clavulanic acid combination in our clinical setting. Conclusion. Consequently, there is a need to reassess the empiric antibiotic prescribed for the management of community-acquired peritonitis., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2024 The Authors.)

Appendicitis, typically caused by appendiceal lumen obstruction, is a prevalent abdominal surgical emergency worldwide. While most cases involve Enterobacterales, Haemophilus influenzae , primarily known for upper respiratory infections, is infrequently associated with gastrointestinal infections. This article presents an exceptional case of acute appendicitis caused by both Haemophilus influenza and Enterobacter cloacae in a 15-year-old child, highlighting the significance of recognizing uncommon pathogens in appendicitis and emphasizing the necessity for thorough microbiological investigations to refine diagnostic approaches., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2024 The Authors.)

Tuberculosis is an infectious disease that most often affects the lungs, caused by human-to-human transmission of Mycobacterium tuberculosis . Peritoneal tuberculosis is an extra-pulmonary form of the disease that usually manifests as an ascitic syndrome, with or without fever, in a context of altered general condition, often in endemic areas. The diagnosis of peritoneal tuberculosis is not always easy, as the clinical signs are often insidious and unspecific. We report a case of peritoneal tuberculosis in an 18-year-old female, who had presented for 10 days with a progressive increase in abdominal volume associated with vomiting and diarrhoea., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2024 The Authors.)
