Rothia spp. are Gram-positive cocco-bacilli that cause a wide range of serious infections, especially in immunocompromised hosts. Risk factors for mucilaginosa (previously known as Stomatococcus mucilaginosus) bacteremia include prolonged and profound neutropenia, malignancy, an indwelling vascular foreign body. Here, we describe 67 adults at the Mayo Clinic Rochester, MN, from 2002 to 2012 with blood cultures positive Rothia. Twenty-five these patients had multiple cultures, indicating true...

Gordonia species are ubiquitous aerobic actinomycetes that rarely cause infection in humans. We report the second known case of otitidis catheter-related bacteremia an immunocompromised patient and review four additional cases seen at our institution over past 14 years. In addition, existing literature on infections is reviewed.

A patient with asplenia and multiple red blood cell transfusions acquired babesiosis infection Babesia divergens–like/MO-1 organisms not microti, the common United States species. He had no known tick exposure. This is believed to be first transfusion-transmitted case fifth documented of B. infection.

Acute transverse myelitis (ATM) is a rare, potentially devastating neurological syndrome that has variety of causes, infectious being one them. Lyme disease (LD) the most common vector borne zoonosis in United States (U.S.). While neurologic complications LD are common, acute an exceedingly rare complication. We present case previously healthy 25-year-old man who presented with secondary erythema migrans, aseptic meningitis and clinical features including bilateral lower extremity motor...

Histoplasma urine antigen (UAg) detection is an important biomarker for histoplasmosis. The clinical significance of low-positive (<0.6 ng/ml) UAg results was evaluated in 25 patients without evidence prior infection. from 12/25 (48%) were considered falsely positive, suggesting that values should be interpreted cautiously.

Abstract The epidemiology of infection after liver transplantation for hilar cholangiocarcinoma has not been systematically investigated. In this study 124 patients, 255 infections occurred in 105 patients during the median follow‐up 4.2 years. time to first was 15.1 weeks ( IQR 1.6‐62.6). most common sites were abdomen, bloodstream, and musculoskeletal system. Risk factors any post‐transplant pre‐transplant VRE colonization (Hazard Ratio [ HR ] 1.9, P =.002), living donor 6.6, &lt;.001),...

Chagas disease (CD) is the third most common parasitic infection globally and can cause cardiac gastrointestinal complications. Around 300,000 carriers of CD live in U.S., with about 3000 those Colorado. We described our experience diagnosing at a Colorado teaching hospital to revise screening eligibility criteria. From 2006 2020, we reviewed Trypanosoma cruzi (TC) IgG serology results for 1156 patients institution. identified 23 (1.99%) who had positive test. A total 14/23 (60%) serologies...
