Inguinal syndrome secondary toPrevotella biviaafter accidental bite in orogenital sex

Abstract

The authors report a case of an inguinal bubo in a young man caused by an anaerobe, Prevotella bivia, which was acquired during oral sexual intercourse. As far as the authors know, this is the first reported case of a sexually transmitted infection by Prevotella. Prevotella spp. inhabit the oral cavity and are highly prevalent in bacterial vaginosis, a polymicrobial syndrome resulting from replacement of the normal vaginal Lactobacillus spp. flora by high concentrations of anaerobic microorganisms such as Prevotella spp., Mobiluncus spp., Gardnerella vaginalis and other uncultivated anaerobes.

Scrotal Abscess in a Japanese Patient Caused by Prevotella bivia and Streptococcus agalactiae, Successfully Treated with Cefazolin and Amoxicillin: A Case Report

“…Table 2 summarizes previous reports of Prevotella bivia infections as published in PubMed. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Similar to our case, the case presented by Bekasiak et al involved a scrotal abscess and co-infection with a second bacterial genus. 11 Additionally, co-infection occurred in 7 cases, including 2 cases with Prevotella bivia and Streptococcus anginosus, a well-known species that produces an abscess.…”

“…5 Prevotella bivia infections in humans are rare, with only 18 published cases in 44 years. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Since most Prevotella bivia strains are β-lactamase-positive, 24 clindamycin, amoxicillin/clavulanate, metronidazole, and imipenem are the recommended antibacterial agents. 21,25 However, antibiotic resistance varies across countries, 26 and it is unknown whether Prevotella bivia strains in Japan are β-lactamase positive.…”

A rare case of necrotizing fasciitis of the leg in an intravenous drug user caused by Prevotella denticola

“…Prevotella species are anaerobic commensals of the mouth and could contribute to oral inflammatory processes [ 4 ]. Rarely, they can cause cervicofacial infections [ 6 , 7 ], peritoneal and pelvic cavity infections ( P. bivia and P. disiens ) [ 8 ], surgical or human bite wound infections [ 9 ], and hepatosplenic abscesses [ 10 ]. Cases of NF caused by Prevotella spp.…”

Post Arthrotomy Prevotella bivia Septic Arthritis and Secondary Osteomyelitis

“…Male genitourinary tract has also been reportedly affected; Nalmas et al [8) reported P. bivia causing a penile abscess requiring surgical drainage. Sagristà et al [9] described a case of inguinal bubo in a young male acquired as part of sexually transmitted infection. Other rare case reports secondary to P. bivia include Necrotising Fasciitis [10], abdominal wall phlebitis following renal transplantation and inferior vena cava obstruction [11], chest wall abscess [12], and P. bivia associated Lemierre Syndrome [13].…”
