Actinomyces odontolyticus, a component of normal human flora, has been implicated in cervicofacial actinomycosis, which most commonly involves the perimandibular soft tissues and is characterized by slowly progressive abscess and sinus tract formation. Actinomycosis has rarely been reported to involve the larynx, and the imaging findings of laryngeal involvement have not been reported. We present a case of laryngeal actinomycosis with findings on computed tomography, magnetic resonance imaging, and positron emission tomography.

spp. are filamentous gram-positive bacilli found in humans as a common flora of the oropharynx, gastrointestinal tract, and urogenital tract. Actinobacteria are normally present in the gums and are a common cause of infection in dental procedures and oral abscesses. To date, no cases of causing meningitis and cervical abscess have been reported in online databases. Therefore, we report the first case of meningitis and recurrent cervical abscess due to translocation from the oral cavity.

Review
BACKGROUND
The combined infection of actinomyces odontolyticus sepsis and cryptococcal encephalitis is rare in routine clinical practice. Thus, we presented this case report and literature review to provide clues to improve such patients' diagnoses and treatment processes.
CASE PRESENTATION
The main clinical manifestations of the patient were high fever and intracranial hypertension. Then, we completed the routine cerebrospinal fluid examination, biochemical detection, cytological examination, bacterial culture, and India ink staining. Firstly, the blood culture suggested actinomyces odontolyticus infection, considering the possibility of actinomyces odontolyticus sepsis and intracranial actinomyces odontolyticus infection. Accordingly, the patient was administered penicillin for treatment. Although the fever was slightly relieved, the symptoms of intracranial hypertension did not relieve. After 7 days, the characteristics of brain magnetic resonance imaging and the results of pathogenic metagenomics sequencing and cryptococcal capsular polysaccharide antigen suggested that cryptococcal infection. Based on the above results, the patient was diagnosed with a combined infection of cryptococcal meningoencephalitis and actinomyces odontolyticus sepsis. Anti-infection therapy with 'penicillin, amphotericin, and fluconazole' was provided, improving the clinical manifestations and objective indexes.
CONCLUSION
The combined infection of Actinomyces odontolyticus sepsis and cryptococcal encephalitis is first reported in this case report, and combined antibiotics with 'penicillin, amphotericin, and fluconazole' are effective.

Actinomyces Odontolyticus is a gram-positive bacillus, usually found in the oropharynx, gastrointestinal and urogenital tracts, as commensal flora. Infections caused by this organism are rare but may occur, more commonly in immunocompromised patients. We report a case of a 54-year-old man, who presented to the emergency department (ED), with fever and chills. The patient had undergone an implantable cardioverter defibrillator (ICD) insertion, 5 months prior to his arrival, and was diagnosed with Actinomyces Odontolyticus bacteremia, during the hospitalization. Transesophageal echocardiogram (TEE) revealed vegetations on the tricuspid valve and the ICD electrode. This is the first reported case of ICD related Actinomyces endocarditis and bacteremia based on our literature review. This case emphasizes the importance of probing for the source of actinomyces infection, while considering the indolent properties of the disease.

Abdominal actinomycosis is a rare infection and the non-recognition of this particular microorganism may led to a prolonged septic process and recurrent disease. We hereby present a case report of 53 years-old woman with a secondary peritonitis due to this microorganism and our option to perform a long course of penicillin derived antibiotics, after suture of a perforated gastric ulcer caused by a foreign body.

Actinomyces species are opportunistic pathogens, difficult to isolate, and often accompanied by other pathogens. We report the case of an immunocompetent woman who presented with respiratory distress and was discovered to have a right-sided empyema requiring chest tube drainage. species and were isolated in pleural fluid cultures. Initial empiric broad-spectrum antibiotic therapy and chest tube placement failed to show clinical improvement. Upon isolation of Actinomyces, the treatment was streamlined to ampicillin/sulbactam while pleural drainage continued, producing significant clinical status improvement in the patient. Given the known co-pathogenicity of Actinomyces species and the difficulty in isolating Actinomyces, it is essential to consider antibiotic coverage for Actinomyces species in those with Streptococcus species empyema.

INTRODUCTION AND IMPORTANCE
Manifestations of infection by include thoracic, abdominal, pelvic, and central nervous system disease. In the four decades following its isolation, more than 20 cases of invasive infections were reported in multiple geographic locations including the United States and Europe. As such, is an emerging bacterium and related research is encouraged for further characterization of its prevalence and clinical significance. Our case series represents the first case series about bacteremia in the state of Qatar.
METHODS
We are reporting 15 cases with isolated positive blood cultures at Hamad Medical Corporation, State of Qatar from 1/Jan/2016 to 1/Nov/2020. Electronic health records (EHR) of patients who were identified to have positive blood cultures were accessed and the demographics and other clinically related data were collected and mentioned in this manuscript, after obtaining the appropriate approval from the Corporation Medical Research Council (MRC).
OUTCOMES
We are reporting 15 cases with isolated positive blood cultures at Hamad Medical Corporation, State of Qatar from 1/Jan/2016 to 1/Nov/2020.
CONCLUSION
12 of the 15 reported cases were considered significant and received a complete course of antimicrobial therapy. The patients presented with a wide variety of clinical pictures and were of variable age.
