Genetic Divergence of Vibrio vulnificus Clinical Isolates with Mild to Severe Outcomes.

The marine bacterium Vibrio vulnificus infects humans via food or water contamination, leading to serious manifestations, including gastroenteritis, wound infections, and septic shock. Previous studies suggest phylogenetic Lineage 1 isolates with the v allele of the gene cause human infections, whereas Lineage 2 isolates with the allele are less pathogenic. Mouse studies suggest that some variants of the primary toxin could drive more serious infections.

Safety and efficacy of chronic suppressive azole therapy for endemic fungal infections in solid organ transplant recipients.

Background: Although the research is limited, treatment guidelines recommend lifelong suppressive azole therapy for disseminated endemic fungal infection (EFI) after solid organ transplantation (SOT). Suppressive azole therapy may prevent EFI recurrence at the risk of hepatotoxicity and drug interactions. We present real-world safety and effectiveness data of chronic suppressive azole therapy for EFI in SOT recipients over a 10-year period at a single comprehensive transplant center.

Draft Genome Sequences of Two Strains Associated with Gastroenteritis after Raw Seafood Ingestion in Colorado.

is a Gram-negative pathogen associated with gastrointestinal and wound infections after exposure to raw seafood or contaminated waters. We report here the whole-genome sequences of two stool isolates (CDC-AM50933 and CDC-AM43539) from patients in Colorado presenting with gastroenteritis after ingesting raw seafood.

Efficacy of Ceftriaxone, Cefepime, Doxycycline, Ciprofloxacin, and Combination Therapy for Vibrio vulnificus Foodborne Septicemia.

Foodborne infections are associated with higher rates of sepsis and mortality than wound infections; however, antibiotic efficacy studies have not been performed in foodborne infection models. The efficacies of ceftriaxone, cefepime, doxycycline, ciprofloxacin, and combination therapy were assessed in intestinal infection in mice in order to model foodborne infections. In accordance with prior studies of cefotaxime, cefepime was synergistic with doxycycline and ciprofloxacin ; combination therapy significantly decreased bacterial growth, by ≥2 log units, from that with antibiotic monotherapy ( < 0.

Purpureocillium lilacinum tattoo-related skin infection in a kidney transplant recipient.

Purpureocillium lilacinum is an emerging pathogenic mold among immunocompromised hosts that causes cutaneous infections related to skin breakdown. We present the first reported case of P. lilacinum tattoo-related skin infection, to our knowledge.
