Does influenza virus prefer dry or moist air?
Influenza virus is often more transmissible in cold, dry air because low humidity levels can weaken the respiratory mucosal lining and make it easier for the virus to infect. However, it can still spread in moist air through respiratory droplets when an infected person coughs or sneezes.
How many people have been killed by measles?
It's impossible to find that information out. In 2006 a 13 year old boy died of measles, first death in more than a decade.
So, yearly, statistically, 0.10% children die of measles or 1 in 10 years die of measles in the UK.
Thanks to vaccinations, we are now fairly safe from diseases like measles, but unfortunately as the rate of vaccinations goes down (due to fear mongering) some of these diseases are coming back.
If you are using this information to decide whether or not to vaccinate your child, remember that 200,000 people died of measles last year - in unvaccinated countries. Talk to your doctor and make the sensible decision.
Are germs and bacteria the same thing?
Germ is non medical term of microorganism which includes parasite, amoeba, fungus, bacteria, richetchia, virus, and so many others.
Bacteria is one of the germ. usually the germ causes disease, but some germ are good for us, so called friendly germ.
What are three types of opportunistic infections?
What are the symptoms of hantavirus?
Hantavirus has an incubation time of 2–4 weeks in humans, before symptoms of infection occur. These symptoms can be split into five phases: Febrile phase: Symptoms include fever, chills, malaise, headaches, nausea, abdominal and back pain, respiratory problems such as the ones common in the influenza virus, as well as gastro-intestinal problems. These symptoms normally occur for 3–7 days. Hypotensive phase: This occurs when the blood platelet levels drop and symptoms can lead to tachycardia and hypoxemia. This phase can last for 2 days. Oliguric phase: This phase lasts for 3–7 days and is characterised by the onset of renal failure and proteinuria occurs. Diuretic phase: This is characterized by diuresis of 3–6L per day, which can last for a couple of days up to weeks. Convalescent phase: This is normally when recovery occurs and symptoms begin to improve.
Where are the most germs in the kitchen?
Either the trash or the dish drainer of your kitchen sink. I think I recall a special on Discover about myths of bacteria in your home and if I remember correctly, the kitchen sink was said to be one of the most bacteria infested items in a kitchen.
What is an example of good bacteria?
One of the example is the GUT FLORA. It is needed of our body to break down food remains that have not been digested earlier in the digestive system and to discourage harmful bacteria and yeasts from invading the body. It also produces beneficial substances like vitamin K.
Another one is Lactobacillus acidophilus, which is a bacterium that turns milk into yogurt.
How does Clostridium Perfringens attack and spread?
The mechanism for clostridium botulinum is that it prevents vesicle fusion of the neurotransmitter acetylcholine at the neuromuscular junction, where neurons connect with muscle. Acetylcholine is the molecule responsible for telling your muscle to move and botulism prevents this chemical messenger from leaving the neuron and reaching the muscle. The end results is silence, or paralysis. The tetanus toxin works in a similar way, however it prevents inhibitory chemical messages (glycine and GABA) from reaching the muscle and the end results is hyperactivity, or tetanus. Both result in paralysis.
What is the most common injury of anthrax?
Farm animals. Although, in the US we vaccinate farm animals against anthrax. World wide, however, sheep and cows are the most common victims of anthrax. It is more of a livestock disease than a human one. Humans are certainly susceptible to anthrax and if you walk around barefoot on a farm with an open cut you may find yourself with an anthrax infection. Anthrax is not very dangerous unless it is prepared as a weapon. You are in more danger from influenza or pneumonia. ;)
What illness does spirilla cause?
Spirilla are known to cause various illnesses in humans, such as leptospirosis, a bacterial infection that can result in symptoms ranging from mild flu-like illness to severe manifestations like kidney damage and meningitis. Spirilla can also cause other diseases like syphilis and certain types of food poisoning.
Is influenza autotroph or heterotroph?
Influenza is a virus and thus does not fit into either the autotroph or heterotroph classification. Viruses are obligate intracellular parasites that require a host cell to replicate and cannot carry out metabolic processes on their own.
The Parasite that causes malaria is a type of what?
The parasite that causes malaria is a type of Plasmodium, a genus that contains over 100 different types of microscopic parasites. It is transmitted through the bite of an infected mosquito.
Does klebsiella produce red pigment?
Some strains of Klebsiella, such as Klebsiella pneumoniae, can produce a red pigment called prodigiosin. This pigment is most commonly associated with other bacterial species like Serratia marcescens. Klebsiella strains that produce red pigment are not as common.
Will anal cause e coli in pee?
Intercourse or stimulation in the anal area can introduce bacteria from the rectum, potentially leading to urinary tract infections (UTIs) caused by E. coli. It is important to practice good hygiene, use protection like condoms, and communicate openly with your partner to minimize the risk of infection. If you experience symptoms of a UTI, such as frequent urination, pain, or cloudy urine, seek medical advice promptly.
What is the best treatment for cocci bacteria?
The best treatment for cocci bacteria is typically a course of antibiotics prescribed by a healthcare provider. Commonly used antibiotics for cocci infections include ciprofloxacin, doxycycline, and sulfamethoxazole-trimethoprim. It is important to complete the full course of antibiotics as prescribed to ensure complete eradication of the bacteria.
What does Klebsiella look like?
Klebsiella bacteria are rod-shaped (bacilli) and have a characteristic polysaccharide capsule that surrounds the cell, giving a mucoid appearance on agar plates. Its colonies typically appear smooth, raised, and mucoid with a sticky consistency. Klebsiella can come in various colors, including pink, white, yellow, or cream, depending on the growth conditions and the type of media used for culture.
Does Clostridium Botulinum have a cell wall?
Yes, Clostridium botulinum is a Gram-positive bacterium that has a cell wall composed of peptidoglycan. The cell wall provides structural support and helps protect the bacterium from external pressures.
How does the body react to Influenza?
White blood cells attack the flu virus inside your body, trying to destroy them for you. This is one way the body reacts to the flu. Another way is that your skin blocks out most of the viruses trying to get into your body. Hope this is helpful. :)
Parasitic roots are specialized roots that attach to the roots of host plants to obtain water, nutrients, and structural support. They do not have chlorophyll and rely on the host plant for their survival. Common examples of parasitic plants with parasitic roots include mistletoe and dodder.
Distinguish among pathogenic deficiency hereditary and physiological disease?
Pathogenic diseases are caused by what is called a pathogen. Pathogens are parasitic organisms that cause disease int heir host. There are five different groups of pathogens: Viruses, bacteria, fungi, protozoans and parasitic worms.
Deficiency diseases are just as the name suggests. They are caused by a deficiency of a particular nutrient in the diet.
Hereditary diseases are passed on through generations via their genes. For example, haemophilia and sickle cell disease. They cannot be cured.
Physiological diseases are caused by the failure or malfunction of body parts or organs
Is influenza caused by bacteria?
No, influenza is caused by viruses, specifically the influenza virus. Influenza viruses can infect the respiratory tract and lead to symptoms such as fever, cough, and body aches. Antibiotics, which are used to treat bacterial infections, are not effective against the influenza virus.
You know viruses are not alive because?
viruses do not have the ability to replicate on their own or carry out metabolic functions like living organisms do. They require a host cell to reproduce and do not possess the machinery needed to do so independently.
What does anthrax do to your body?
Anthrax is a serious infectious disease caused by the bacterium Bacillus anthracis. When anthrax spores enter the body, they can cause severe illness by producing toxins that can damage cells and tissues. Symptoms of anthrax can vary depending on how the infection enters the body but can include fever, malaise, cough, and difficulty breathing. Severe cases of anthrax can be fatal if not promptly treated with antibiotics.
How does the vaccine that contains cowpox virus prevent smallpox?
the cow pox and smallpox are the same thing. they give the body a tiny bit of the virus and let the body kill it immediately. the body gets so little of the virus that it can easily kill it, then it will become immune. the only thing is the side affects of this vaccine--stomach ache, nausea, pain, headache, and the seldom fate of death. in the early 1970's, the people got rid of most fatal side affects and it is now given to infants. now smallpox (cow pox) is virtually impossible to get the virus.
