We report the case of a male in his early 70s who developed a deep infection after an open rotator cuff repair, with as the only organism isolated from a surgical biopsy of the tendon remnants and phlegmatic/purulent material at the failed repair site. This species was originally within the genus . We report this case because it is the only one that we could locate where an infected open rotator cuff repair site grew . Our patient was not diabetic, did not smoke, and did not have other recent or concurrent infections. He had hypertension, hypothyroidism, depression, and a hyperactive bladder. Hence, he only had minor risk factors for infection. His postoperative shoulder infection was eradicated with surgical irrigation and debridement, and 6.5 weeks of primarily oral antibiotic treatment. We also review the literature on infections after any shoulder surgery where or species were isolated.

Schaalia turicensis, a Gram-positive bacillus, is a potential pathogen in genital infections. Here, we report the complete genome sequence of S. turicensis strain CT001, which was coisolated with Neisseria gonorrhoeae. Comprehensive analysis revealed the presence of a composite transposon carrying an imperfect class 1 integron in S. turicensis.

Review
organisms reside on mucosal surfaces of the oropharynx and the genitourinary tract. Polymicrobial infections with organisms are increasingly being reported in the literature. Since these infections differ from classical actinomycosis, lacking of specific clinical and imaging findings, slow-growing organisms can be regarded as contaminants or insignificant findings. In addition, only limited knowledge is available about novel species and their clinical relevance. The recent reclassifications have resulted in the transfer of several species to novel genera , , , , or . The spectrum of diseases associated with specific members of and these related genera varies. In human infections, the most common species are Actinomyces , , and , which are typical inhabitants of the mouth, and , , and . In this narrative review, the purpose was to gather information on the emerging role of specific organisms within the and related genera in polymicrobial infections. These include in pulmonary infections, in brain abscesses and infections in the lower respiratory tract, in skin-related infections, in necrotizing fasciitis and skin abscesses, and in infected tissues around prostheses and devices. Increased understanding of the role of and related species in polymicrobial infections could provide improved outcomes for patient care. Key messages Due to the reclassification of the genus, many former species belong to novel genera , , , , or .Some of the species play emerging roles in specific infection types in humans.Increasing awareness of their clinical relevance as an established or a putative pathogen in polymicrobial infections brings about improved outcomes for patient care.

Clinical Laboratory Dec 2023Urachal remnants (URs) represent uncommon and underdiagnosed entities that are usually detected incidentally at imaging or present clinically different manifestations.
BACKGROUND
Urachal remnants (URs) represent uncommon and underdiagnosed entities that are usually detected incidentally at imaging or present clinically different manifestations.
METHODS
Here we presented a boy with UR infection. Ultrasonography and bacterial culture and identification were performed. He received antibiotic treatment and underwent surgical excision of the cyst.
RESULTS
The patient presented with both a urachal cyst and umbilical-urachal sinus. UR infection was caused by Actinomyces turicensis. He recovered well from the operation without complications.
CONCLUSIONS
The present case reminds clinicians to be familiar with imaging features of different types of URs and their potential complications and indicates the necessity of pathogenic microorganism analysis to tailor antibiotic treatment and post-operative follow-up to prevent complications.

BACKGROUND
Fournier's gangrene (FG), a urological emergency with high mortality, is an infectious necrotizing fasciitis of the perineal and genital regions. The majority of FG is caused by polymicrobial organisms involving mixed aerobes and anaerobes but rarely reveals Actinomyces species.
CASE PRESENTATION
We report a healthy 67-year-old Asian male who presented with rapidly progressive painful swelling of the scrotum. Clinically diagnosed with FG, the patient underwent an emergency radical debridement, followed by broad-spectrum antibiotics and negative pressure wound therapy. The identification of the causative microorganisms showed Actinomyces turicensis and the antibiotic treatment was adjusted accordingly. After wound bed preparation, we took split-thickness skin grafts to cover the scrotal wound. Active management to minimize faecal contamination was applied throughout the whole course of treatment and repair. The patient was satisfied with the outcome. This was an extremely rare case of A. turicensis as the main causative pathogen of FG.
CONCLUSIONS
FG due to Actinomyces species is rarely reported, but we should still consider this pathogenic microorganism that has long been neglected.

Actinomycosis is a rare chronic infection, caused by species of the bacterium spp. This report proposes oral breast trauma as a cause of infection. An adult female in her 30s presented with a recurrent left breast abscess to a local hospital. She had previously undergone nine operations for abscess in the past 2 years. Shortly prior to her first presentation, a sexual partner with reported dental infection bit her periareolar area. The treating team noted that her bacterial culture from the first operation was positive for spp. She was treated with long-term intravenous antibiotics and had no further recurrences of infection. Oral trauma to the periareolar area by an individual with pre-existing dental disease has led to the introduction and establishment of this pathogen in the ductal system of the breast. This infection should be considered in cases of treatment resistant recurrent breast abscess.

A 42-year-old man was referred to the Department of Orthopedic Surgery with pain over his right greater trochanter and signs of systemic infection. CT showed an enhanced mass in his gluteus maximus as well as gas in the biceps femoris over the underlying hip joint. Tissue biopsy yielded Fusobacterium nucleatum and Actinomyces turicensis. The patient was successfully treated for 6 weeks with amoxicillin/clavulanic acid 875mg/125mg and metronidazole 500mg.

Our case report describes a patient with a common presenting complaint yet an uncommon infection. Our patient presented with a fluctuant breast mass diagnosed as a breast abscess. An aspirate sample was sent for culture and sensitivities, which revealed the presence of and the anaerobe She was therefore prescribed several weeks of amoxicillin and metronidazole, and made a full recovery. There are only three case reports describing as a causative organism for breast abscess, one of which had also occurred in our department. One case also showed the additional presence of Our findings reveal a growing need for increasing clinician awareness of and the importance of aspirate sample culture and sensitivity.
