Prolonged exposure to sunlight can harm human skin, causing issues like sunburn, skin cancer, and oxidative stress. To counteract these effects, kojic acid is used in cosmetics like creams and lotions because it can inhibit hyperpigmentation. Kojic acid is also used in the food industry to prevent browning. Due to its wide range of uses in cosmetics, food, and pharmaceuticals, among other...

Hepatitis A virus (HAV) is a common human pathogen causing acute hepatitis. Human HAV belongs to species Hepatovirus A, genus Hepatovirus, family Picornaviridae. HAV strains of Hepatovirus A are only found in humans (genotypes I-III) and monkeys (genotypes IV-VI), with no non-primate reservoir host. We screened serum and faeces of 70 alpacas and llamas from Bolivia for novel viruses using...

Dust can contain microorganisms that are both pathogenic and resistant to antimicrobials (AMR), which can potentially transmit airborne infectious and zoonotic diseases. Agriculture is one of the largest producers of primary particle matter, accounting for approximately 20% of global fine dust emissions. The tenacity of aerosolised pathogens depends on the characteristics of the particles,...

Schistosomiasis (Bilharzia) is a Neglected Tropical Disease caused by trematode parasites, with Schistosoma haematobium being a primary cause of urogenital Schistosomiasis in sub-Saharan Africa (SSA). After a prepatent period, paired adult worms produce eggs in the venous plexus of the bladder, which are shed in urine from infected humans. However, some eggs become trapped in... -

Q fever is caused by Coxiella burnetii (Cb), a zoonotic pathogen mainly shed by ruminants during abortion or parturition. Human infection can occur through inhalation of contaminated aerosols. Although a commercial vaccine exists for ruminants, it can induce adverse reactions and does not fully prevent bacterial shedding, highlighting the need for a more effective and safer vaccine. The...

Shiga toxin-producing Escherichia coli (STEC) are important food-borne pathogens. The severity of clinical symptoms can vary from diarrhea to haemolytic-uremic syndrome and death. In STEC, the Shiga toxin subtype and the occurrence of additional virulence factors have an impact on the clinical manifestation. STEC from food can vary in serotype and virulence associated genes (VAGs) from those...

Egyptian rousette bats (ERBs) are natural reservoirs of Marburg virus (MARV, family Filoviridae) – etiologic agent of viral hemorrhagic fever with high mortality rates in humans and non-human primates. Recent studies have sought to better understand the immune-related features that grant bats the ability to asymptomatically harbor zoonotic viruses. To elucidate mechanisms of MARV co-adaptation...
