The HACEK group of bacteria (Haemophilus spp., Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, Kingella spp.), is uncommon pathogens of infective endocarditis, but can cause life-threatening events such as heart failure or formation of lethal emboli. Here we report a 58-year-old Asian man with a past history of congenital valvular heart disease who presented with sudden onset of left flank pain followed by fever with chills for 2 weeks. Abdominal computed tomography (CT) indicated a 1.6 cm abscess in the spleen. Culturing indicated the presence of Haemophilus aphrophilus. We diagnosed the patient with subacute endocarditis complicated with spleen abscess. The patient recovered fully after two weeks antibiotic (Ceftriaxone) treatment. Clinicians should give further attention to infective endocarditis caused by bacteria in the HACEK group in patients with metastatic infection such as spleen abscess with suspected valvular heart disease.

Spontaneous Resolution and Recurrence of Aseptic Splenic Abscesses in a Patient With Newly Diagnosed Crohn's Disease.
Cureus
December 2024
Internal Medicine - Gastroenterology, Faculty of Medical Sciences, Lebanese University, Beirut, LBN.
Aseptic splenic abscesses are rare in the early phases of Crohn's disease and are typically reported in patients with longstanding illness or uncontrolled symptoms despite medical treatment. We present a case of recurrent aseptic splenic abscesses in a young man newly diagnosed with Crohn's disease, whose illness remained well-controlled. This unique case raises questions regarding the spontaneous resolution of aseptic splenic abscesses without steroid therapy and their recurrence without acute Crohn's disease flare-ups.

Fatal Feline Leukemia Virus-Associated Enteritis in a Wild Eurasian Lynx () in Germany.
Biology (Basel)
November 2024
Department of Pathology, University of Veterinary Medicine Hannover, 30559 Hannover, Germany.
The Eurasian lynx (), a widespread wild felid on the Eurasian continent, is currently classified as "critically endangered" in Germany. Understanding the impact of infectious agents is of particular importance for the continued conservation of these animals, especially regarding pathogens with broad host ranges and risk of interspecies transmission. Feline leukemia virus (FeLV) is known to infect wild and domestic felids worldwide, including several species of lynx, but it has not been reported thus far in the Eurasian lynx.

Background: Yersinia pseudotuberculosis is an emerging zoonotic intestinal pathogen primarily transmitted through contaminated food and water. Infections caused by Yersinia pseudotuberculosis are typically self-limiting, often presenting as gastroenteritis or "pseudoappendicitis," which is characterized by fever and abdominal pain. Although bloodstream infections with Yersinia pseudotuberculosis are rare, they can lead to multiple distant sites of infection, including abscesses in the liver, spleen, and kidneys, as well as in the hip and knee joints, particularly in individuals with underlying immunodeficiency.
