La Crosse encephalitis virus, TEM
La Crosse encephalitis virus. Coloured transmission electron micrograph (TEM) of La Cross (LAC) encephalitis virus particles (virions). Each particle consists of an icosahedral protein coat (capsid, yellow rings) surrounding single-stranded ribonucleic acid (RNA), the virus genetic material. This virus is an arbovirus (arthropod-borne virus), being transmitted to humans by mosquitos, but it can also spread through bites from infected mammals. In humans, symptoms can be severe, the worst being seizures, coma, paralysis and permanent brain damage from encephalitis (brain inflammation). The virus was first discovered in 1963 in La Crosse, Wisconsin, USA

EDITORS COMMENTS
This print showcases the La Crosse encephalitis virus, a menacing arbovirus transmitted to humans through mosquito bites. The image reveals the intricate structure of this pathogenic microbe, with each virion consisting of a vibrant yellow icosahedral protein coat enveloping single-stranded ribonucleic acid (RNA), which serves as its genetic material. Discovered in 1963 in La Crosse, Wisconsin, USA, this virus has since posed a significant threat to human health. Infection can lead to severe symptoms including seizures, coma, paralysis, and permanent brain damage caused by encephalitis or inflammation of the brain. The transmission electron micrograph offers valuable insights into the morphology and composition of this infectious agent. The false-colored representation enhances our understanding of its complex biology and highlights key features for scientific analysis. This visual depiction aids researchers in studying the mechanisms behind viral replication and identifying potential targets for therapeutic interventions. As an arthropod-borne virus (arbovirus), it is crucial to comprehend that not only mosquitoes but also infected mammals can serve as vectors for spreading this disease. Therefore, comprehensive knowledge about its transmission dynamics is essential for effective prevention strategies. Through continuous research efforts in virology and medical microbiology, scientists strive to unravel the mysteries surrounding such pathogens. This remarkable image from Science Photo Library serves as a powerful reminder of both the beauty and danger that exist within our microscopic world—a testament to humanity's ongoing battle against infectious diseases like La Crosse encephalitis virus.
