In this report we describe three cases of Aspergillus flavus sternal wound infection following cardiac surgery. All three cases occurred in a 3-month period coinciding with hospital renovation activities. The patients were successfully treated with combined surgical and medical therapy.

Maize is one of the major crops that are susceptible to infection and subsequent aflatoxin contamination, which poses a serious health threat to humans and domestic animals. Here, an RNA interference (RNAi) approach called Host-Induced Gene Silencing (HIGS) was employed to suppress the -methyl transferase gene (, also called ), a key gene involved in aflatoxin biosynthesis. An RNAi vector carrying part of the gene was introduced into the B104 maize line.

is a medically relevant fungus, particularly in tropical regions. Although its aflatoxin production and thermotolerance are well documented, its biofilm-forming ability has received less attention, despite being a key factor in the virulence of as an opportunistic pathogen, which can significantly impact therapeutic outcomes. To investigate the influence of temperature on the growth and biofilm formation of an isolate, we compared it on solid media with the reference strain ATCC 22546 and documented morphological changes during conidial germination.

A 54-year-old female was presented who suffered from diabetes mellitus and end-stage renal disease presenting with severe otalgia, initially thought to be necrotizing otitis externa. She rapidly progressed to total necrosis of the tympanic membrane.

Background: Aflatoxin B1 (AFB1) is a secondary metabolite produced by Aspergillus flavus and Aspergillus parasiticus. This toxin is highly carcinogenic and toxic, posing a serious threat to human and animal health. AFB1 primarily enters the human body through contaminated food, particularly peanuts, corn, nuts, and wheat.
