What is clostridium anthracis?
Clostridium anthracis is a bacterium that causes anthrax, a serious infectious disease primarily affecting livestock and occasionally humans. It can form spores that can survive in the environment for long periods of time, leading to the potential for outbreaks in animal populations or human exposure through contact with contaminated animal products. Anthrax can be treated with antibiotics if promptly diagnosed.
How can be bacterial food poisonings be prevented?
There are many different bacterium. The method is to avoid them, and to retard their growth. Heat does not kill all bacterium. Some bacterium require a lack of oxygen (anaerobic), and other require oxygen (aerobic. Botulism poisoning comes from the clostridium botulinin. Clostridim Botulinin is an anaerobic bacterium. Freezing the bacterium will only preserve it. Exposure to air will kill it. People love garlic. So too does the bacterium. Do not store garlic under oil or water. Keep it exposed to air and sunlight. Some bacterium will grow in any environment. Salmonella typhi can not be controlled by O2. It causes typhoid fever.
While Botulinum toxin blocks the release of acetylcholine the tetanoid toxin actually blocks the release of GABA. How would the effects of tetanoid toxin exposure be different from the results of BT?
The blocking of GABA release will cause convulsions, where as the blocking of acetylcholine will cause paralysis.
What can tetanus do to your open cuts in your body?
The causative bacterium is Clostridium tetani, and it isn't a problem in open wounds because oxygen kills the bacteria. However, in deep wounds that do not have exposure to atmospheric oxygen, C. tetani will multiply and create the tetanus exotoxin, which is then released into the surrounding tissues. This toxin causes your nerves to fire spasmodically, which locks your muscles into rigid paralysis and is extremely painful. Without treatment, tetanus is typically a fatal condition.
What is habituation in infant?
The best way that I can explain this to you is if you hold up a blue card (stimulus) to an infant, at first they may become interested. After continuous exposure to that card they become uninterested in it anymore (habituated). So in the technical terms after continuous exposure to a stimulus it is common for an infant even adults to become habituated to that stimulus.
What is the deadman function on exposure button?
The deadman function is a safety feature that requires continuous pressure to be applied to the exposure button in order to keep the X-ray tube activated. If the pressure is released during the exposure, the X-ray beam will automatically shut off, reducing the risk of unnecessary radiation exposure.
How do insecticides inhibit cholinesterase?
Electrical switching centers, called 'synapses' are found throughout the nervous systems of humans, other vertebrates, and insects. Muscles, glands, and nerve fibers called 'neurons' are stimulated or inhibited by the constant firing of signals across these synapses. Stimulating signals are usually carried by a chemical called 'acetylcholine' (a-see-till-ko-leen). Stimulating signals are discontinued by a specific type of cholinesterase enzyme, acetylcholinesterase, which breaks down the acetylcholine. These important chemical reactions are usually going on all the time at a very fast rate, with acetylcholine causing stimulation and acetylcholinesterase ending the signal. If cholinesterase-affecting insecticides are present in the synapses, however, this situation is thrown out of balance. The presence of cholinesterase inhibiting chemicals prevents the breakdown of acetylcholine. Acetylcholine can then build up, causing a "jam" in the nervous system. Thus, when a person receives to great an exposure to cholinesterase inhibiting compounds, the body is unable to break down the acetylcholine
What has the author Karel Soudijn written?
Karel Soudijn is a Dutch author known for his book "Emergency and Continuous Exposure Guidance Levels for Selected Submarine Contaminants." This book provides guidance for safe exposure levels to contaminants on submarines.
How does bacteria spread in tetanus?
Tetanus is a medical condition characterized by a prolonged contraction of skeletal muscle fibers. The primary symptoms are caused by tetanospasmin, a neurotoxin produced by the Gram-positive, obligate anaerobic bacterium Clostridium tetani. Infection generally occurs through wound contamination and often involves a cut or deep puncture wound. As the infection progresses, muscle spasms develop in the jaw (thus the name "lockjaw") and elsewhere in the body.[1] Infection can be prevented by proper immunization and by post-exposure prophylaxis.[2]
What is the safe continuous ozone exposure for natural rubber?
Zero. Rubber samples (natural and manmade) are aged at accelerated rates, by exposing them to elevated ozone levels, temperature, and humidity.
Mention some common problems or defects that can effect 5 sense organs?
hi five .. continuous exposure to same environment eating fast drinking in standing position
What is the odor of NH4OH?
The odor of NH4OH is very pungent in fact you can't even smell it after a fraction of second and continuous exposure for more than 20 - 30 minutes will be fatal.
