In general, microorganisms that can make you sick are termed "germs" by the non-medical world. Bacteria that can cause disease or sickness are termed "pathogens." There are way too many to list here and certain strains of microorganisms can be harmful while other strains of that same organism may not be.
Viruses make us feel ill by invading our cells and causing damage to our tissues. This triggers an immune response that can lead to symptoms such as fever, muscle aches, and fatigue as our body fights off the infection. Additionally, the toxins produced by viruses can contribute to the symptoms of illness.
The microorganism in yogurt, typically probiotic bacteria like Lactobacillus bulgaricus and Streptococcus thermophilus, help us by aiding in digestion, boosting the immune system, and promoting gut health. These "good" bacteria can help maintain a balanced gut microbiome, which is important for overall health and well-being.
Clostridium botulinum is an example of a microorganism that is anaerobic, meaning it can survive and grow in environments with little to no oxygen. This bacterium is responsible for causing botulism, a serious illness that can result from consuming food contaminated with its toxin.
Sensory stimuli such as sight, sound, touch, taste, and smell can affect our perception and behavior. For example, bright lights can make us feel alert, loud noises can make us feel anxious, and pleasant smells can make us feel relaxed. These stimuli can influence how we interpret and react to our surroundings.
Viruses make us sick by invading our bodies and hijacking our cells to replicate themselves. This process can damage our cells and tissues, leading to symptoms of illness as our immune system responds to the infection.
no
Any microorganism can make us ill once it colonizes. For example, on your skin right now are varieties of bacteria along with yeast. This normal flora does not make us ill (usually). But if something gets out of balance, the bacteria or yeast can begin to multiply. Our bodies initially try to wall off the infection if it is inside our bodies; on the skin, it is harder. If our defenses are low or we cannot fight it off, an infection is well underway.
Because you have aids
Well, you can get ill from depression.
Microbiology is the study of bacteria, virus, fungus, etc. All of these microorganisms can make us ill, sometimes deathly ill. It is important in medicine because scientists must formulate medicine to destroy or inhibit the microorganisms based on their structure. In nursing, they must give patients medicine to fight infections such as these, and monitor them if they are in the hospital. They must also try to control the spread of the microorganism, so they must know what type of microorganism they are infectecd with. Microbiology is the whole basis of health care.
pathogen
microorganisms can be harmful and useful! Yeast is a microorganism and is used in bread. but some bacteria (microorganism) can be harmful, they can make you ill or kill you. but in our imune system there are antibacteria fighting off disease and protecting us. So microorganisms can be harmful and beneficial
Because it is cold which gives us sore throats etc
cross contamination/infection is never good, but the very young and the elderly have weaker immune systems so the infections that just make us a little ill can make them very ill. The illnesses that make us very ill can very likely kill them.
Pathogenic viruses cause illnesses and disease.
tintre
By reproducing and multiplying rapidly. and they make us ill by attacking our cells and converting their normal functions to producing the virus.so they get your own cells to do their dirty work too (this applies for viruses)
