Abstract
Actinotignum schaalii is an anaerobic, gram-positive commensal organism of the urogenital tract. A. schaalii typically causes urinary tract infections, predominantly in the elderly. Here, we describe the first case of A. schaalii infection presenting as cellulitis and abscess in a patient with common variable immunodeficiency. The patient was successfully treated with an incision and drainage and a prolonged antibiotic course. A. schaalii infection should be considered in sterile abscesses, and anaerobic cultures should be requested in the absence of positive routine cultures.

Recurrent obstructive acute pyelonephritis: A rare form of Actinotignum (Actinobaculum) schaalii infection in a HIV-1 infected patient. Anaerobe 2016; 43:75-77.

Abstract
Actinobaculum schaalii is a rarely reported, anaerobic, Gram-positive bacterium which role as uropathogen is emerging. We report here the case of a 47 year old HIV-1 infected woman presented with five recurrent episodes of obstructive pyelonephritis in the context of multiple renal stones. No bacteria was found until the fifth episode, during which prolonged urinary cultures as well as 16S rDNA sequencing allowed the diagnosis of A. schaalii infection. She had developed a life-threatening condition with severe renal failure. A right nephrectomy was performed and found that the intrarenal stones were attributed to the antiretroviral therapy. The renal parenchyma corresponded to an end-stage renal disease with chronic pyelonephritis without abcesses or granules. The situation improved after six months of amoxicillin therapy.

Abstract
The genus Actinotignum contains three species, Actinotignum schaalii (formerly Actinobaculum schaalii), Actinotignum urinale and Actinotignum sanguinis. A. schaalii is the species most frequently involved in human infections, with 172 cases, mostly urinary tract infections (UTIs), reported so far. Invasive infections have also been described. This facultative anaerobic Gram-positive rod is part of the urinary microbiota of healthy patients. It is responsible for UTIs, particularly in elderly men and young children. A. schaalii is an underestimated cause of UTIs because of its fastidious growth on usual media and difficulties associated with its identification using phenotypic methods. Indeed, this slow-growth bacterium requires blood-enriched media and an incubation time of 48 hours under anaerobic or 5% CO2 atmosphere. Furthermore, only matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF) or molecular-based methods allow the accurate identification of this bacteria. MALDI-TOF using Microflex LT with the Biotyper database (Bruker Daltonics, Bremen, Germany) is the most reliable technology for the routine identification of A. schaalii. The identification of this uropathogen is all the more important because it is resistant to trimethoprim/sulfamethoxazole and second-generation quinolones that are widely used in the treatment of UTIs. Antimicrobial therapy using β-lactams prolonged for up to 2 weeks is the most efficient treatment and should be recommended. Microbiologists should assess the presence of A. schaalii in urine using appropriate culture and identification methods in the case of a direct examination that is positive for small coccoid rods, a negative nitrite urinary stick associated with leukocyturia, treatment failure with trimethoprim/sulfamethoxazole or fluoroquinolones, or undocumented, repeated UTIs.

A validation of the Danish microbiology database (MiBa) and incidence rate of Actinotignum schaalii (Actinobaculum schaalii) bacteraemia in Denmark. Clin Microbiol Infect 2015; 21:1097.e1-4. [PMID: 26319901 DOI: 10.1016/j.cmi.2015.08.006] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2015] [Revised: 08/05/2015] [Accepted: 08/17/2015] [Indexed: 11/22/2022]
Abstract
Actinotignum schaalii (former named Actinobaculum schaalii) can cause urinary tract infections (UTIs) and bacteraemia, mainly in the elderly. A. schaalii is difficult to identify with conventional biochemical tests, and it is often overlooked if the urine is only cultured in ambient air. The aim of this study was to validate data from the nationwide Danish microbiology database (MiBa) with data from the laboratory information system (LIS) at the local department of microbiology in Viborg-Herning, and to evaluate the incidence rate of bacteraemia caused by A. schaalii in Denmark by using data from the MiBa. All departments of microbiology in Denmark report data to the MiBa. All microbiological samples with A. schaalii in Denmark were extracted for a period of 5 years from the MiBa and from the local LISs. All data obtained from our local LIS were also found in the MiBa, except for data on real-time PCR, which were not registered, owing to missing ID codes in the MiBa. From 2010 to 2014, there was a significant increase in the incidence rate of blood cultures with A. schaalii, from 1.8 to 6.8 cases per million, which was probably due to coincident implementation of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) in routine diagnostics. We found that A. schaalii caused bacteraemia and UTIs mainly in the elderly. In conclusion, the MiBa can be a useful source of nationwide microbiological data in Denmark. Our results suggest that the incidence rate of A. schaalii as a cause of bacteraemia has been underestimated, and that culture of urine in CO2 can improve the detection of A. schaalii.

Abstract
INTRODUCTION Technological advances during the last years in bacterial identification by molecular biology and mass spectrometry, or Matrix Assisted Laser Desorption Ionisation-Time of Flight (MALDI-TOF) have allowed identifying new bacteria involved in urinary tract infections. The purpose of this review is to familiarize clinicians with these bacteria so that they can look at a particular target population and help biologists to suspect and identify them. METHOD A bibliographic research was performed using the Medline database concerning the keywords Aerococcus, Actinobaculum, Alloscardovia, Trueperella. RESULTS If Aerococcus sp. is now well known, Actinobaculum sp., Alloscardovia sp. and Trueperella sp. remain rarely isolated and unknown from clinicians. Importance of these germs could be underestimated because of the identifying and isolation difficulties which existed beforehand. They are particularly found in a population of elderly people with underlying conditions or urological risk factors of urinary tract infection. Actinobaculum schaalii is also found more frequently in young children. CONCLUSION Aerococcus sp. et A. schaalii are true uropathogens not to be underestimated. Further studies are still needed to confirm the specific involvement of Trueperella and Alloscardovia in urinary diseases.

Abstract
Complete genome sequencing of the emerging uropathogen Actinobaculum schaalii indicates that an important mechanism of its virulence is attachment pili, which allow the organism to adhere to the surface of animal cells, greatly enhancing the ability of this organism to colonize the urinary tract.
