Another kind of cell death, the pyroptosis, is induced by Salmonella typhimurium and Pseudomonas aeruginosa and Shigella flexneri and the lethal toxin of Bacillus anthracis. Therefore, recently scientists utilize cytotoxic properties of bacterial toxins for designing novel anti-tumor drugs....
Some potentially effective compounds that have been discovered include certain bacterial toxins and antimicrobial peptides. Novel treatment strategies, such as combining synergistic antibiotics to boost the killing of bacteria, are also under investigation. It may be possible to introduce compounds into ...
Bacteria are microscopic single-cell organisms that are neither plants nor animals. They are simple and ancient organisms; and there is evidence of bacterial life on earth 3.5 billion years ago. Bacteria are characterized by a lack of bound internal structures. Bacteria are among the smallest organ...
a number of bacterialspeciesgive off toxins that in turn may damage tissues. Bacteria are generally large enough to be seen under a lightmicroscope. Streptococci, the bacteria that causescarlet fever, are about 0.75 micrometer (0.00003 inch) indiameter. Thespirochetes, which causesyphilis,leptospiro...
When the researchers implanted these bacteria from FAP patients into mice, they found that mice with only one species developed few tumors, whereas mice that were colonized with both bacterial species were substantially more prone to invasive cancer and death. ...
Bacterial toxins play major roles in developing infections and can cause diverse morphological and physiological changes via certain biochemical mechanisms leading to cell death. Most of the bacterial toxins induce apoptosis in host cell by intrinsic and extrinsic apoptosis pathways that are caused by int...
There are more than 200 known infectious contaminant causes / types of food poisoning and foodborne illness. Some of the most common causes are: Bacteria that cause food poisoning The most common cause of the majority of food poisoning instances can be linked to a bacterial contaminant. In many...
Cellulitis is an acute spreading bacterial infection below the surface of the skin characterized by redness, warmth, inflammation, and pain. The most common cause of cellulitis is the bacteria staph (Staphylococcus aureus). Cirrhosis Cirrhosis of the liver refers to a disease in which normal liver...
Vaccine, suspension of weakened or killed microorganisms or toxins or other biological preparation, such as those consisting of antibodies, lymphocytes, or mRNA, that is administered to prevent disease. Vaccines work by stimulating the immune system to a
of the nose may reveal ulcers and vesicles (small sacs containing liquid), as infoot-and-mouth disease, aviral diseaseof cattle, or vesicular exanthema, a viral disease of swine. Ulceration of the tongue may be apparent in animals suffering from actinobacillosis, a disease of bacterial ...
