Legionella - pathogenic Gram negative bacterium. Acquired its name after a July, 1976 outbreak of a then-unknown "mystery disease" sickened 221 persons, causing 34 deaths. The outbreak was first noticed among people attending a convention of the American Legion - an association of U.S. military veterans
False-color TEM of the bacteria Campylobacter jejuni. These Gram-negative bacteria, curved or spiral in shape, have flagellae (whip- like tails) at either pole of the cell giving them a darting mobility.
Giardiasis is a diarrheal illness caused by the parasite Giardia intestinalis (also known as Giardia lamblia or Giardia duodenalis). A parasite is an organism that feeds off of another to survive. Giardiasis is a global disease. It infects nearly 2% of adults and 6% to 8% of children in developed countries worldwide. Nearly 33% of people in developing countries have had giardiasis. In the United States, Giardia infection is the most common intestinal parasitic disease affecting humans.
Toxic marine Dinoflagellate (Karenia brevis) Toxic marine Dinoflagellate (Karenia brevis) that causes red tide. This gymnodinioid dinoflagellate has an equatorial groove containing one undulating flagellum and a second flagellum that trails behind the cell. They produce the brevetoxin which affects the central nervous system of fish, and people can become ill with neurotoxic shellfish poisoning when they eat shellfish that have accumulated brevetoxin.
Most people know the four blood types, A, B, AB, and O but lesser known are the Japanese personality traits associated with each blood type. (Hmm ???) This infographic contains blood related facts such as blood donation requirements, diseases requiring blood donations, and more.
MRSA bacteria. Coloured scanning electron micrograph (SEM) of methicillin-resistant Staphylococcus aureus (MRSA, red) on the microscopic fibres of a wound dressing. MRSA is a gram-positive, round (coccus) bacterium that is resistant to many commonly prescribed antibiotics. It is carried by around 30 per cent of the population without causing any symptoms. However, in vulnerable people, such as those that have recently had surgery, it can cause wound infections, pneumonia and blood poisoning…
Salmonella enteritidis. Salmonella Enteritidis and Salmonella Typhimurium are the most common in the United States and account for half of all human infections. Strains that cause no symptoms in animals can make people sick, and vice versa. If present in food, it does not usually affect the taste, smell, or appearance of the food. The bacteria live in the intestinal tracts of infected animals and humans. Photo by Jean Guard-Petter. USDA
Gonorrhea, once a minor illness, is developing resistance to the last category of drugs that still works against it and could become untreatable - common human sexually transmitted infection caused by the bacterium "Neisseria gonorrhoeae."
How Scientists Stalked a Lethal Superbug—With the Killer’s Own DNA
Scientists Stalk a Lethal Superbug with Killer's Own DNA: KPC, carbapenem-resistant Klebsiella pneumoniae can hitch a ride on healthy people, setting up residence on their skin. It can spread to people with weak defenses, bloom into an overwhelming infection that spreads via bloodstream into whole body, swiftly shutting down one organ after another. In past decade, KPC has evolved ability to withstand every known antibiotic. Roughly half of people who develop an active infection will die.
