Diabetic ketoacidosis is a feared complication in patients with diabetes mellitus and poses high risk of mortality and morbidity unless treated in timely manner. Infection is one of the most common precipitating factors for the development of diabetic ketoacidosis. Bacteremia with Group A and Group B beta hemolytic streptococcal strains are well known, however nonenterococcal Group D strains such as the Streptococcus bovis/Streptococcus equinus complex (SBSEC) still remains an understudied entity. Here we present a case of a 35-year-old Type I diabetic female presenting with severe diabetic ketoacidosis with overlapping features of hyperosmolar hyperglycemia, precipitated by Streptococcus alactolyticus bacteremia, successfully treated with four-week course of parenteral ceftriaxone...

Burkholderia pseudomallei is recognized to cause severe and fatal infections. Most of the infections caused by this facultative intracellular gram-negative bacterium are pneumonia, soft tissue, genito-urinary and central nervous system infection. We report an unusual case of primary prostatic abscess complicated by perianal abscess caused by Burkholderia pseudomallei. Melioidosis related anorectal infections have not been previously reported in the literature.

Lyme disease may present with a variety of cardiac manifestations ranging from first degree to third degree heart block. Cardiac involvement with Lyme disease may be asymptomatic, or symptomatic. Atrioventrical conduction abnormalities are the most common manifestation of Lyme carditis. Less common, are alternating right bundle branch block (RBBB) and left bundle branch block (LBBB). We present an interesting case of a young male whose main manifestation of Lyme carditis was isolated LBBB. He also had mild Lyme myocarditis...

We present a case of fatal community-acquired pneumonia (CAP) due to Acinetobacter baumannii, which is rarely reported in the northeastern United States. Previously reported cases originate from tropical and subtropical climates, and infection tends to have an aggressive course with a poor outcome. Appropriate antimicrobial therapy is crucial; however, the associated systemic inflammatory response may overwhelm host defenses, especially in patients with certain co-morbidities.

Histoplasma capsulatum, a dimorphic fungus found world-wide, is endemic to regions of the Mississippi and Ohio River valleys and portions of Central and South America. Initial infection can present with acute pulmonary symptoms or remain clinically asymptomatic, with disease course generally guided by degree of inoculum and underlying immunosuppression. A chronic, progressive course of weight loss, oral ulceration, and fatigue has been associated with elderly males. We present a 79-year-old man with a chronic, progressive course of oral lesions, odynophagia, and weight loss who was found to have histoplasmosis on oral biopsy performed for suspicions of oropharyngeal squamous cell carcinoma...

Listeria rhombencephalitis (LRE) is a rare encephalitis of the hindbrain that can present with a variety of neurological symptoms. It is a diagnostic challenge, but prompt antimicrobial therapy is important to prevent high rates of mortality and morbidity. We report two cases of LRE, with several contrasting clinical features and different disease courses. Despite being rare, it is important to consider listeria in patients with possible meningoencephalitis, even if cultures are negative. Empirical treatment of meningoencephalitis should provide coverage for listeria, especially if the patient is at risk of listeriosis or there is a potential history of listeria exposure...

We report the first case of infective endocarditis following urinary tract infection (UTI) caused by Globicatella sanguinis in an 87-year-old Japanese woman with recurrent episodes of UTI. We identified the pathogen using the Rapid ID32 Strep system. Accurate identification of this infection is important and essential for the effective antimicrobial coverage to this pathogen.

This case presents a hydatid cyst of the thigh in a 57-year-old patient born and raised in rural Montenegro. He presented with a painful erythematous mass on the lateral aspect of the right thigh at the site of a previous cystic mass resection 13 years earlier. Complete surgical resection was conducted, histopathology revealed laminated membranes and polymerase chain reaction was positive for Echinococcus granulosus. Primary musculoskeletal hydatidosis is a rare entity and diagnosis is challenging. Any cystic lesion in a patient from an endemic area should raise the possibility of echinococcosis, regardless of anatomic location...

We present a case report of a 58-year- old woman with subarachnoid haemorrhage complicated by non-communicating hydrocephalus. During the course of her neurosurgical management, she developed external-ventricular drain associated ventriculitis which in turn was complicated by lack of communication between third and fourth ventricles. The causative organism was a fully-sensitive Acinetobacter baumanii, a nosocomial pathogen often associated with complicated treatment regimens and poor outcomes. This patient was successfully managed by a multi-disciplinary team involving neurosurgeons, neuroradiologists and infection specialists...

A carbapenem resistant but ceftriaxone and cefepime susceptible Klebsiella oxytoca was isolated from the blood of a patient with polymicrobial bacteremia after 2 weeks of ertapenem treatment. Whole-genome sequencing identified no carbapenemase gene nor plasmid, but only blaOXY-2-8 gene with a mutation in the promoter that's been reported to increase its expression. Two other specific carbapenem resistance mechanisms including mutated porin genes and the AcrAB-TolC efflux system genes were also identified. Clinicians need to be aware of such unusual antibiogram and should not assume carbapenems are always broader spectrum antibiotics than expanded-spectrum cephalosporins...

Sphingomonas paucimobilis is a strictly aerobic, non-spore-forming Gram-negative bacillus, ubiquitous bacterium, thought to be an opportunistic pathogen and is rarely reported in clinical settings. Here in, is the first case report of Acute Sphingomonas phlebitis secondary to intravenous (IV) drug use. We present the case of a 39-year-old male who initially presented with pain in his right upper extremity, fevers and chills of three week duration. He admitted to regularly injecting heroin in his distal right upper extremity with visible erythema, tenderness and streaking along the path of vein along the injection site...

Introduction: Bacterial meningitis may relapse after adequate antibiotic treatment. In most cases, however, the pathophysiology cannot be identified. Presentation of case: We describe a preterm infant with recurrent episodes of meningitis due to infection with an identical Escherichia coli strain both at birth and at 10 days after cessation of a 3 week course of appropriate antibiotic treatment. At the time of recurrence, the patient presented with fulminant severe cardiac failure due to acute myocarditis, coupled with a concurrent echovirus 18 infection (confirmed by stool culture and serological analysis)...

Introduction: Lactobacillus species causing infective endocarditis is rare. Most reported cases arise from the oral ingestion of Lactobacillus via dairy or nutritional supplements in patients with congenital valve disease or replacement. We present a case of native valve bacterial endocarditis caused by Lactobacillus arising from dental abscesses. Additionally, there was an error in identification of the Lactobacillus as Corynebacterium, which led to inadequate treatment. Presentation of case: A 51-year-old male presented to an outside clinic with several weeks of subjective fevers and malaise...

Cupriavidus gilardii was first identified as an aerobic, gram-negative, glucose-nonfermenting rod. C. gilardii has been characterized as an organism with low pathogenicity that causes opportunistic infections and few case reports of infection caused by this organism previously. We encountered the first case of bloodstream infection caused in China by C. gilardii in a 87-year old man without obvious immunodeficiency. The isolate were identified as C. gilardii by 16S rRNA sequencing. The infected patient was treated according to the laboratory's antibiogram of this strain...

Primary Cytomegalovirus (CMV) infection is often not suspected as a cause of fever of unknown origin (FUO) in immune-competent adults. We present a case-series of symptomatic primary CMV infection in immunocompetent adults presenting as fever of unknown origin (FUO). All patients with CMV serology tested between November 2008 and June 2016 underwent chart review. Cases were defined as those between 18 and 65 years of age with documented fever and elevated serum anti-CMV IgM. Exclusion criteria were organ specific CMV disease, positive serum anti-EBV IgM, or presence of any immunocompromising condition...
