Review
BACKGROUND
Oligella is an uncommon Gram-negative coccobacillus that was first thought to belong to the urogenital tract. The genus Oligella comprises two species that were recovered from various samples worldwide.
METHODS
We perform a systematic review focusing on Oligella microbiological characteristics, habitat, role in Human microbiome and infection, and antimicrobial susceptibility.
RESULTS
In humans, Oligella is mainly found as part of the microbiome of individuals with predisposing conditions. Oligella were also associated with invasive infections in patients with underlying diseases. Nevertheless, their prevalence remains to determine. Oligella culture requires up to 48 h on agar media in vitro, while urinary samples are usually incubated for 24 h. Consequently, microbiologists should be prompt to prolong the incubation of agar media when the direct examination showed Gram-negative coccobacilli. Oligella is accurately identified using MALDI-TOF mass spectrometry, but biochemical methods often provided inconsistent results. Specific guidelines for antimicrobial susceptibility testing of Oligella lack but the incubation could require up to 48 h of incubation. In contrast to O. urethralis, which is susceptible to third-generation cephalosporin, O. ureolytica is likely resistant to numerous antimicrobials. Genectic determinants of resistance were identified for beta-lactams and aminoglycosides.
CONCLUSION
Oligella is an uncommon pathogen that can be underrecognized. Microbiologists should be prompt to prolong the incubation of agar media plated with urines when the direct examination showed Gram-negative coccobacilli. Carbapenems should probably be given for the empirical treatment.

Oligella urethralis (O. urethralis) is an organism that rarely causes infections in humans. We report the case of a 90-year-old bedridden woman with progressive dementia who was placed in a long-term-care facility. She was admitted to our hospital due to fever and unconsciousness with pyuria. The abdominal computed tomography showed left pneumatosis and urinary stone. Fluoroquinolones-resistant O. urethralis, which was identified by the Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) and the 16S rRNA gene sequencing, was isolated form the blood and urine cultures at admission. To the best of our knowledge, this is the first case of emphysematous pyelonephritis caused by O. urethralis.

is a commensal bacteria genus of the human urinary tract that rarely precipitates clinical infections. We report the case of an asymptomatic 24-year-old male with a medical history of Tourette syndrome and the recent placement of deep brain stimulator leads, which were found to be co-infected with species during hardware implantation. This is the first reported case of a deep brain stimulator infection by , a potentially under-recognized and emerging opportunistic bacteria. We review the previously published cases of extra-genitourinary infections and detail the clinical management of this uncommon pathogen.

are opportunistic pathogens typically associated with genitourinary infections. Here, we report the complete genome for an isolate recovered from ear discharge of a child with chronic suppurative otitis media (strain MSHR-50412PR). The genome comprises 2.58 Mb, with 2,448 coding sequences and 46.26% average GC content.

This study was undertaken to investigate the bacterial and fungal microflora on the external genitalia of a population of healthy male donkeys in the state of Michigan, USA. The aim was to identify and determine the frequency of occurrence of these microorganisms using seven different isolation media and standard microbiological procedures. The sites (urethral fossa [fossa glandis], dorsal diverticulum of the urethral sinus, distal urethra, and penile surface) in the distal reproductive tract were cultured and each isolated microorganism identified. Ten different genera of gram-positive bacteria, eight different genera of gram-negative bacteria, and two genera of fungi were isolated from the external genitalia of the 43 donkeys in this study. All 43 donkeys yielded gram-positive bacteria (2-8 species) from all four sites sampled. Arcanobacterium spp., Corynebacterium spp., and Bacillus spp. were the most frequently isolated gram-positive bacteria. Gram-negative bacteria were cultured from 16 (37.2%) of the 43 donkeys, with Acinetobacterlwoffii (16.3%), Oligella urethralis (11.6%), and Taylorellaasinigenitalis (9.3%), the most frequently isolated. Fungi were cultured from only 5 (11.6%) of the 43 donkeys, with Rhizopus spp. isolated from 3 (7.0%) and Cladosporium spp. from 2 (4.7%) individuals. The testes and epididymides collected from 40 donkeys at time of castration were culture negative. Few differences were found in the bacterial flora between prepubertal and mature intact and castrated donkeys. Of notable interest was the scarcity of known equine pathogens across the population tested and isolation of T. asinigenitalis from normal donkeys, especially prepubertal individuals and previously castrated males.

An 82-year-old bedridden man with sequelae from a cerebral infarction was admitted to a welfare institution for the elderly. He developed a high fever and hematuria and was prescribed levofloxacin for the treatment of a suspected urinary tract infection. Although his condition improved, the symptoms subsequently recurred; therefore, levofloxacin was again administered. He remained febrile and was admitted to a hospital due to recalcitrant urinary tract infection. Immediately after admission, he developed ischuria and pyuria. Urine and blood cultures at admission indicated the presence of levofloxacin-resistant Oligella urethralis (O. urethralis). He recovered with ceftriaxone medication. To our knowledge, this is the first report of bacteremia associated with a urinary tract infection caused by O. urethralis in Japan.
