Xochitecatl [ʃot͡ʃiˈtekat͡ɬ] is a pre-Columbian archaeological site located in the Mexican State of Tlaxcala, 18 km southwest of Tlaxcala city. [1] The major architecture dates to the Middle Preclassic Period (1000–400 BC) but occupation continued, with one major interruption, until the Late Classic , when the site was abandoned.
It induces lytic development in certain bacteria that contain prophages. [7] Colibactin has been previously demonstrated to have a characteristic mutational signature. [ 8 ] The same mutational signature was discovered in several cohorts of colon cancer patients, and in smaller numbers of patients with urogenital and head and neck cancers.
Scarlet fever is caused by a toxin produced by group A streptococcus (the bacteria that causes a strep throat infection) and presents as a rash on the face or neck, and spreads to the chest, torso ...
Bacteria involved in causing and treating cancers. Cancer bacteria are bacteria infectious organisms that are known or suspected to cause cancer. [1] While cancer-associated bacteria have long been considered to be opportunistic (i.e., infecting healthy tissues after cancer has already established itself), there is some evidence that bacteria may be directly carcinogenic.
Bacteria involved in causing and treating cancers. This is a list of bacteria that have been identified as promoting or causing: Uncontrolled growth of tissue in the body; Cancer; Carcinomas; Tumors (including benign or slow growing) Neoplasms; Sarcomas; Precancerous lesions; Coinfectious agent promoting the above growths
The most researched bacteria for cancer therapy are Salmonella, Listeria, and Clostridium. A genetically engineered strain of Salmonella (TAPET-CD) has completed phase 1 clinical trials for patients with stage 4 metastatic cancer. [11] Listeria-based cancer vaccines are currently being produced and are undergoing many clinical trials. [12]
Basal-cell carcinoma (BCC), also known as basal-cell cancer, basalioma [7] or rodent ulcer, [8] is the most common type of skin cancer. [2] It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it . [ 1 ]
Streptococcus is a genus of gram-positive or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. [2] Cell division in streptococci occurs along a single axis , thus when growing they tend to form pairs or chains, which may appear bent or twisted.
