Deinococcus radiodurans is a bacterium, an extremophile and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile. The Guinness Book Of World Records listed it in January 1998 [1] as the world's most radiation-resistant bacterium or lifeform. [2]
Radioresistance is the level of ionizing radiation that organisms are able to withstand.. Ionizing-radiation-resistant organisms (IRRO) were defined as organisms for which the dose of acute ionizing radiation (IR) required to achieve 90% reduction (D10) is greater than 1,000 gray (Gy) [1]
Feline disease refers to infections or illnesses that affect cats. They may cause symptoms, sickness or the death of the animal. Some diseases are symptomatic in one cat but asymptomatic in others. Feline diseases are often opportunistic and tend to be more serious in cats that already have concurrent sicknesses.
A standardized plan for the management of febrile, neutropenic patients must be devised in each institution or agency., [9] [10] Empirical regimens must contain antibiotics broadly active against Gram-negative aerobic bacteria (a quinolones [i.e. ciprofloxacin, levofloxacin], a fourth-generation cephalosporins [e.g. cefepime, ceftazidime], or ...
On April 30, a report published in the Centers for Disease Control and Prevention’s Emerging Infectious Diseases journal took a deep dive into the highly pathogenic avian influenza. HPAI H5N1 ...
A University of California, Davis study of dead sea otters collected from 1998 to 2004 found toxoplasmosis was the cause of death for 13% of the animals. [163] Proximity to freshwater outflows into the ocean was a major risk factor. Ingestion of oocysts from cat feces is considered to be the most likely ultimate source. [164]
Cancer in cats is the leading cause of death among cats. It is caused by uncontrolled cell growth, and affects a wide range of cell types and organs in the body. It is caused by uncontrolled cell growth, and affects a wide range of cell types and organs in the body.
Kittens are more likely to carry the bacteria in their blood, so may be more likely to transmit the disease than adult cats. [10] However, fleas serve as a vector for transmission of B. henselae among cats, [ 5 ] and viable B. henselae are excreted in the feces of Ctenocephalides felis , the cat flea. [ 11 ]
