Two rare cases of pleural infection due to Prevotella species

Abstract

replacement was initiated. A hormonal study was performed showing increased levels of TSH (31.59), antibodies antiperoxidase (>1000 UI/mL) and decreased levels of thyroxine (<0.28 ng/dL). Moreover, the antinuclear antibodies were positives. The patient was diagnosed of systemic lupus erythematosus and myxedematous coma. Later, a chest ultrasound revealed a left pleural effusion; drainage was then performed.Both pleural fluids were sent to the microbiology laboratory for culture. The two samples were inoculated onto both aerobic and anaerobic blood agar (Becton Dickinson), chocolate agar (Becton Dickinson), and thioglycolate broth (Becton Dickinson), incubating all media at 37º C for 5 days. Gram staining of both fluids exhibited abundant Gramnegative rods. On the second day of incubation, numerous Two rare cases of pleural infection due to Prevotella species

SARS-CoV-2 genetic variation and bacterial communities of naso-oropharyngeal samples in middle-aged and elderly COVID-19 patients in West Java, Indonesia

“…However, this bacterium is also an opportunistic pathogen capable of invasively causing pneumonia, infection in the respiratory tract, and pleuropulmonary in rare cases. 50 , 51 Despite this different niche between the four bacteria, all of them share a similarity in that some of their strains have a potential antibiotic resistance, 12 , 48 , 50 , 52 so their existence in the upper respiratory tract should be given more attention.…”

Two cases of Prevotella oris causing serious pleuropulmonary infections

“…Previously, P. oris has been associated with clinical pictures such as abscesses or bacteremia, among others [3,4]. Although rare, it has also been described causing pleuropulmonary infections in the form of pneumonia and pleural empyema in both adult and pediatric populations [2,[5][6][7][8]. Both the article by Viswanath LS et al and Cobo F et al describe cases in which P. oris are an unequivocal cause of pleural pathology.…”

“…In terms of treatment, control of the focus by draining the collections associated with antibiotics would be of choice [5][6][7][8]. In recent years, antimicrobial resistance is increasing among anaerobic anaerobic bacteria worldwide.…”

A Case of Streptococcus intermedius Abscess Within a Malignant Neck Mass and Review of the Literature

“…The remainder of the cases identified in our literature search were cancer patients who developed S. intermedius abscesses but who had not received radiation treatment. [8][9][10][11][12][13][14][15][16][17][18][19][20][21] One of these patients, like our patient, had tonsillar squamous cell carcinoma; however, this patient presented with a neck abscess before cancer diagnosis. 12…”
