Viral and bacterial infections have many similarities. Both are cause by microorganisms that are spread through coughing, sneezing, kissing or having sex with an infection person. As well as touching objects, eating food or drinking water contaminat with microorganisms that can cause infection and disease. However, viral and bacterial infections have many different characteristics.
Bacteria are small, single-celled organisms that are quite complex. They have a rigid cell wall that allows them to maintain their shape. Inside the bacterial cell, there is a fluid that is surround by a thin, rubbery membrane. Bacteria can live on their own and can make food. They can also survive in a variety of environments คาสิโนออนไลน์ UFABET ฝากถอนรวดเร็ว เริ่มต้นเล่นง่าย. Whether it is in hot, cold, radioactive waste, or inside the human body, bacteria can survive in all of these places.
Although most bacteria are beneficial and harmless, helping the digestive system, destroying pathogenic microbes, fighting cancer cells and providing essential nutrients to the body, some bacteria, or less than 1 percent of all bacteria, can cause various diseases and illnesses.
Viruses are simple, uncomplicated organisms that are smaller than bacteria. The largest viruses are smaller than the smallest bacteria. All viruses have a core of nucleic acid, which is RNA or DNA, and are surround by proteins. The survival and growth of viruses are different from bacteria because viruses cannot reproduce on their own. They need to grow and reproduce in the cells of living things.
And most viruses can cause disease, and some viruses attack specific cells, such as those that attack liver cells, those that attack the respiratory system, those that attack the bloodstream, and sometimes viruses attack bacteria.
Some diseases, such as pneumonia, meningitis, or diarrhea, can be cause by either viruses or bacteria. The doctor will examine the body and medical history to find the cause of the illness. However, some patients may need additional diagnostic methods, such as blood tests, urine tests, or biopsies, to confirm the exact cause of the disease and allow the patient to receive appropriate treatment.
