BACKGROUND
This case series investigated the clinical manifestations, diagnoses, and treatment of cerebral abscesses caused by . We retrospectively analyzed the clinical characteristics and outcomes of three cases of cerebral abscesses caused by and conducted a comprehensive review of relevant literature.
CASE SUMMARY
Case 1 presented with a history of left otitis media and exhibited high fever, confusion, and vomiting as primary symptoms. Postoperative pus culture indicated a brain abscess caused by infection. Case 2 experienced dizziness for two days as the primary symptom. Postoperative pus culture suggested an intermediate streptococcal brain abscess. Case 3: Enhanced head magnetic resonance imaging (MRI) and diffusion-weighted imaging revealed occupancy of the left temporal lobe, initially suspected to be a metastatic tumor. However, a postoperative pus culture confirmed the presence of a brain abscess caused by infection. The three cases presented in this case series were all patients with community-acquired brain abscesses resulting from angina caused by Streptococcus group infection. All three patients demonstrated sensitivity to penicillin, ceftriaxone, vancomycin, linezolid, chloramphenicol, and levofloxacin. Successful treatment was achieved through stereotaxic puncture, drainage, and ceftriaxone administration with a six -week course of antibiotics.
CONCLUSION
Preoperative enhanced head MRI plays a critical role in distinguishing brain tumors from abscesses. Selecting the correct early diagnostic methods for brain abscesses and providing timely intervention are very important. This case series was in accordance with the CARE guidelines.

UNLABELLED
is a gram-positive commensal bacterium commonly found in the oropharynx, gastrointestinal and urogenital tracts. It might be an aggressive opportunistic pathogen causing invasive pyogenic infections in sterile areas, mostly as peritonsillar and orofacial abscesses. We report the case of a 6-year-old girl, who presented multiple head and neck abscesses and bilateral cavernous sinus thrombosis secondary to . Cavernous sinus thrombosis, consequent to this microorganism, has not been reported to date in the literature. Due to the invasive features of this pathogen, a long-term antibiotherapy (up to 9 months) is required. Additionally, a surgical drainage is indicated in case of head and neck, or brain abscesses, larger than 20 or 25 mm respectively. Anticoagulation should be considered in case of venous thrombosis. The interest of this case is not only based on the rarity and severity of the disease, but also on the success of medical and surgical therapy (including long- term antibiotics, anticoagulation and two surgical procedures). This experience may serve as a guide to treat future cases.

Exploring the microbiota difference of bronchoalveolar lavage fluid between community-acquired pneumonia with or without COPD based on metagenomic sequencing: a retrospective study.
BACKGROUND
Community-acquired pneumonia (CAP) patients with chronic obstructive pulmonary disease (COPD) have higher disease severity and mortality compared to those without COPD. However, deep investigation into microbiome distribution of lower respiratory tract of CAP with or without COPD was unknown.
METHODS
So we used metagenomic next generation sequencing (mNGS) to explore the microbiome differences between the two groups.
RESULTS
Thirty-six CAP without COPD and 11 CAP with COPD cases were retrieved. Bronchoalveolar lavage fluid (BALF) was collected and analyzed using untargeted mNGS and bioinformatic analysis. mNGS revealed that CAP with COPD group was abundant with Streptococcus, Prevotella, Bordetella at genus level and Cutibacterium acnes, Rothia mucilaginosa, Bordetella genomosp. 6 at species level. While CAP without COPD group was abundant with Ralstonia, Prevotella, Streptococcus at genus level and Ralstonia pickettii, Rothia mucilaginosa, Prevotella melaninogenica at species level. Meanwhile, both alpha and beta microbiome diversity was similar between groups. Linear discriminant analysis found that pa-raburkholderia, corynebacterium tuberculostearicum and staphylococcus hominis were more enriched in CAP without COPD group while the abundance of streptococcus intermedius, streptococcus constellatus, streptococcus milleri, fusarium was higher in CAP with COPD group.
CONCLUSIONS
These findings revealed that concomitant COPD have an mild impact on lower airway microbiome of CAP patients.

brain abscesses are relatively rare. Here, we report our treatment of an anaerobic brain abscess caused by a mixed infection of , and diagnosed by metagenomic next-generation sequencing (mNGS). This is the first reported case of in a brain abscess. This case highlights the possibility that oral anaerobic microbes can cause a brain abscess and demonstrates that mNGS has the potential to be deployed to provide rapid infection diagnosis and rationalize antimicrobial therapy for brain abscesses.

, commonly known as star anise, represents one of the notable botanical species and is recognized for its rich reservoir of diverse bioactive compounds. Beyond its culinary application as a spice, this plant has been extensively utilized in traditional medicine. Given the contemporary emphasis on incorporating natural resources into food production, particularly essential oils, to enhance sensory attributes and extend shelf life, our study seeks to elucidate the chemical composition and evaluate the antibacterial (, ) and insecticidal properties of essential oil (IVEO). Also, microbiological analyses of pumpkin sous vide treated with IVEO after inoculation of were evaluated after 1 and 7 days of study. GC/MS analysis revealed a significantly high amount of ()-anethole (88.4%) in the investigated EO. The disc diffusion method shows that the antibacterial activity of the IVEO ranged from 5.33 () to 10.33 mm (). The lowest minimal inhibition concentration was found against and the minimum biofilm inhibition concertation was found against . In the vapor phase, the best antimicrobial activity was found against in the pears model and against in the beetroot model. The application of the sous vide method in combination with IVEO application decreased the number of microbial counts and eliminated the growth of . The most isolated microbiota identified from the sous vide pumpkin were , , , and . Modifications to the protein composition of biofilm-forming bacteria were suggested by the MALDI TOF MS instigations. The IVEO showed insecticidal potential against . Thanks to the properties of IVEO, our results suggest it can be used in the food industry as a natural supplement to extend the shelf life of foods and as a natural insecticide.

BACKGROUND
A Bartholin's gland abscess is one of the most common infections in women of reproductive age. Although Bartholin's gland abscesses have been reported in prepubertal children, they are rarer in prepubertal children than in adults. Herein, we report a case of bilateral Bartholin's gland abscesses in a 4-year-old girl with vitamin A deficiency.
CASE PRESENTATION
A 4-year-old girl diagnosed with autism spectrum disorder was admitted to the hospital for close examination and treatment because of persistent fever and malaise. The child was a marked fussy eater and was diagnosed with corneal ulceration and night blindness secondary to vitamin A deficiency. Both of the patient's labia were swollen, and a diagnosis of a bilateral Bartholin's gland abscess was made using computed tomography. Incisional drainage was performed under general anesthesia. The patient's postoperative course was uneventful, and she was discharged from the hospital on day 8 after the surgery. During hospitalization, attempts were made to correct the vitamin deficiency by adding nutritional supplements to the diet. Three months after the surgery, no recurrence of abscesses was noted.
CONCLUSIONS
Decreased immunocompetence and mucosal barrier function due to vitamin A deficiency is thought to be the underlying cause of Bartholin's gland abscesses. Although prepubertal Bartholin's gland abscesses have been reported, they are rare. To the best of our knowledge, no reports of bilateral Bartholin's gland abscesses potentially caused by vitamin A deficiency have been reported. When prepubertal girls present with Bartholin's gland abscesses, the presence of immunodeficiency due to vitamin or trace element deficiency should also be considered.

Bilateral Empyema With Beta Hemolytic Group C Streptococcus and Streptococcus constellatus Co-infection Resulting From an Esophageal Perforation and Associated With Septic Shock, Diffuse ST Elevation, and New-Onset Atrial Fibrillation.
Empyema is the collection of pus in the pleural cavity and most times, it occurs unilaterally. It is often associated with underlying pneumonia, but other causes have been identified as well. When it occurs after an esophageal perforation, which in itself is also rare, morbidity and mortality are even higher. Esophageal perforation can cause life-threatening complications due to its close proximity to the vital organs of the mediastinum, necessitating its timely diagnosis and aggressive management. Bacteria forming part of the normal esophageal and oral flora are the most common causative pathogens for empyema from an esophageal perforation. Streptococcus constellatus and group C Streptococci, though both rare and often not taken seriously, have been identified as individual causes of empyema. We present a case of a 58-year-old male who presented with a worsening cough, chest pain, and shortness of breath after choking on a fish bone. He was diagnosed with bilateral loculated empyema resulting from esophageal perforation with the pleural fluid culture isolating both group C streptococcus and Streptococcus constellatus. He also developed respiratory failure, mediastinitis, and septic shock. This case will enable physicians to take empyema caused by these bacteria seriously and also to include esophageal perforation as a differential diagnosis when a patient presents with bilateral empyema associated with chest pain and electrocardiographic changes.

This study aimed to identify and characterize the antimicrobial susceptibility profile of bacteria found in primary endodontic infections in the teeth of patients treated at the Dental Clinic of the University of Ribeirão Preto, São Paulo, Brazil. From September to December 2019, samples were obtained from 21 patients with primary endodontic infections. The collections were carried out in triplicate using paper cones placed close to the total length of the root canal. Bacterial isolation was performed in Brain Heart Infusion agar, Blood agar, and other selective culture media cultured at 37°C for up to 48 h under aerobiosis and microaerophilic conditions. The bacterial species were identified using the Vitek 2 automated system. The disk diffusion method on agar Müeller-Hinton was used to assess antimicrobial susceptibility with the recommended antimicrobials for each identified bacterial species. A total of 49 antibiotics were evaluated. Fifteen of the 21 samples collected showed bacterial growth, and 17 bacterial isolates were found. There were 10 different bacterial species identified: Enterococcus faecalis (four isolates), Streptococcus mitis/oralis (three isolates), Streptococcus anginosus (three isolates) being the most common, followed by Staphylococcus epidermidis, Enterococcus faecium, Streptococcus constellatus, Streptococcus alactolyticus, Enterobacter cloacae, Klebsiella variicola, and Providencia rettgeri (one isolate of each species). The analysis demonstrated significant susceptibility to most of the tested antibiotics. However, some Enterococcus isolates resisted the antibiotic's erythromycin, ciprofloxacin, and tetracycline. A Staphylococcus epidermidis isolate was characterized as multidrug-resistant. Five Streptococcus isolates were non-susceptible to all antibiotics tested.

Lemierre syndrome is characterized by thrombophlebitis of the internal jugular vein (IJV) secondary to bacterial pharyngitis or tonsillitis. Though antibiotic use has made this a rarer syndrome, it can nevertheless manifest in patients presenting with pharyngitis. Herein, we describe a 20-year-old male patient with no relevant medical history presenting with signs concerning for pneumonia and was ultimately diagnosed with Lemierre syndrome with bacteremia. Complications included IJV thrombus with presumed septic emboli to the lungs. The patient was discharged on ampicillin/sulbactam with plans to transition to amoxicillin/clavulanate.
