Hematogenous Route

Septic arthritis is a condition initiated by pathogenic inoculation of joints either by direct or hematogenous route, necessitating immediate medical attention. Among aerobic bacteria, Staphylococcus aureus and Streptococcus spp. are commonly found in association with septic joints. Anaerobes are very rarely involved in the causation of septic arthritis with an estimated rate of <1%. We are presenting a case of septic arthritis of knee joint by Parvimonas micra and Fusobacterium nucleatum, both being constituents of microbial flora in the oral cavity and gastrointestinal tract. Gram stain and anaerobic culture incorporated along with the aerobic culture of synovial fluid have played an important role in the preliminary diagnosis of anaerobic septic arthritis in this case.

Microbiological Stability

Very popular in Belgium, rice tart is a hot pastry sold in bakeries. It is then consumed at home, for dessert or snack. This study is conducted to investigate the microbiological stability of this foodstuff, from the end of baking to end user by consumers. In this purpose, 108 rice tart samples were collected from each of seven bakeries in five Belgium provinces. Physico-chimical analysis in addition to microbiological analysis were carried out in accordance with the European Regulation EC 2073/2005 and with references methods, to enumerate the total microorganisms count, Staphylococcus aureus, Bacillus cereus as well as Enterobacteria, susceptible likely to contaminate the tarts during the production or after baking. Even when the results meet the microbiological safety standards immediately after baking in all bakeries implicated, a significant (p <0,05) increase of mesophilic aerobic bacteria (ranging from <1 to 7 log cfu/g) and B. cereus (> 3,7 log cfu/g) was observed during the storage at nonrefrigerated temperature (28 to 30°C). A post-baking recontamination and other parameters like an insufficient baking time or a non uniform distribution of the oven heat could explain the observed bacteria growth. The present study shows that most rice tarts investigated are microbiologically safe. However, the possible increase of bacteria load in this foodstuff attributable to the favorable aw, pH and temperature conditions, highlight the importance of applying good hygienic practices and compliance with storage conditions after baking to ensure consumer safety.

Sucuk is a fermented sausage widely consumed in Turkey. The ability of different concentrations of nisin to inhibit Staphylococcus aureus in artificially contaminated sucuk was examined. Sucuk dough was prepared, inoculated with S. aureus ATCC 25923 at a level of 106 CFU/g, and then divided into six equal portions to which different concentrations of nisin (0, 25, 50, 100, 150, 200 μg/g) were added. Microbiological (S. aureus, total mesophilic aerobic bacteria, and lactic acid bacteria) and physicochemical (pH, water activity, and moisture) analyses were conducted initially and after 1, 3, 5, 10, 15, 20, 25, 30, 35, and 45 days. S. aureus populations decreased to below detectable limits in sucuk containing 200 or 150 μg of nisin per g after 30 and 35 days of storage, respectively, whereas S. aureus populations in 45-day-old sucuk containing 0, 25, 50, and 100 μg of nisin per g were 5.36, 5.68, 4.10, and 3.54 log CFU/g, respectively. Hence, the addition of nisin at 150 μg/g or greater to sucuk dough can be used to prevent the growth of S. aureus in sucuk during fermentation and subsequent storage.

Septic arthritis of the pubic symphysis is a rare disease. Typical clinical features include fever, pubic or groin pain, pain with hip motion, and painful or waddling gait. Identified predisposing factors to develop an infection in pubic joint include female incontinence surgery or postpartum period; sports, especially soccer; pelvic malignancy; and intravenous drug abuse. The most often identified microorganisms were Staphylococcus aureus and Pseudomonas aeruginosa. Osteomyelitis complicates the majority of cases, and about half of the patients require surgical debridement along with a prolonged antibiotic treatment. We report a case of Streptococcus anginosus septic arthritis of the pubic symphysis. The patient did not have any of the above risk factors.

Final Sample

The objective was to characterize and compare the subgingival microbiota in patients diagnosed according to the World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions 2018. For this cross-sectional study, Spanish and Colombian subjects (characterized as health/gingivitis, periodontitis in stages I-II or stages III-IV) were clinically assessed, and subgingival samples were taken and processed by culture. The comparisons among patients with periodontal status (and between countries) was made using Mann–Whitney, Kruskal–Wallis, ANOVA and chi-square tests. The final sample consisted of 167 subjects. Eikenella corrodens and Parvimonas micra were more frequently detected in health/gingivitis and Porphyromonas gingivalis in periodontitis (p < 0.05). Higher total counts were observed in Colombia (p = 0.036). In Spain, significantly higher levels of P. gingivalis and Campylobacter rectus were observed, and of Tannerella forsythia, P. micra, Prevotella intermedia, Fusobacterium nucleatum, Actinomyces odontolyticus and Capnocytophaga spp. in Colombia (p < 0.001). P. micra was more prevalent in health/gingivitis and stage I-II periodontitis in Colombia, and P. gingivalis in all periodontitis groups in Spain (p < 0.05). As conclusions, significant differences were detected in the microbiota between health/gingivitis and periodontitis, with minor differences between stages of periodontitis. Differences were also relevant between countries, with Colombia showing larger counts and variability of bacterial species.

La artritis séptica es una patología infecciosa aguda que es la afectación de la cápsula articular frecuentemente por bacterias, siendo patógeno bacteriano más frecuente los grupos etarios es el Staphylococcus aureus, también puede ser causada por virus y hongos en menor proporción, en niños usualmente es por vía hematógena. Afecta más a hombres que a mujeres, teniendo una clínica muy inespecífica mayormente en lactantes. Sus síntomas clínicos se caracterizan por la negación a movilizar la articulación afectada, enrojecimiento y aumento de la temperatura local, acompañado en algunos casos de fiebre y síntomas sistémicos como taquicardia y aumento de frecuencia respiratoria. Usualmente su afectación es 90% monoarticular y10% poliarticular. La artritis séptica tiene las articulaciones como cadera, rodilla o codo. Como parte de los exámenes de laboratorio serán de gran utilidad biometría hemática completa, velocidad de eritrosedimentación y proteína creactiva. Debido a las complicaciones y secuelas incapacitantes que ocasiona, es considerada una urgencia médico-quirúrgico; su tratamiento debe ser precoz. Ante la confirmación mediante exámenes de laboratorio, es necesario eltratamiento farmacológico empírico intravenoso para obtener resultados del hemocultivo y cultivos de líquido sinovial que deben ser realizados antes del inicio con el tratamiento antibiótico. Su tratamiento será multidisciplinario.

Prompt Diagnosis

Empyema necessitans (EN) is a rare phenomenon that refers to an insidious extension of the empyema through parietal pleura and subsequent dissection into subcutaneous tissue of the chest wall. A 29-year-old man presented to the hospital with fever and chills a few days after an inadvertent needle stick while injecting heroin. His left forearm was warm with an area of fluctuance. He underwent incision and drainage of the left forearm abscess with fluid submitted for Gram stain and culture. His condition rapidly deteriorated due to sepsis, and he required transfer to the intensive care unit. A new 4 × 3 cm area over the left pectoralis muscle had become increasingly indurated, fluctuant, and erythematous. CT of the chest demonstrated extensive cavitary lung lesions and a large loculated left-sided pleural effusion with extension through the chest wall. TEE revealed a 3 cm complex lesion on the superior septal leaflet of the tricuspid valve. The patient underwent incision and drainage of the pectoralis major EN with placement of a drain. Blood and sputum cultures grew methicillin-susceptible Staphylococcus aureus (MSSA) at which time antibiotic therapy was tailored to oxacillin. Our case highlights a rare occurrence of EN due to MSSA in a patient with intravenous drug use (IDU) and underscores the importance of prompt diagnosis and treatment.
