Which of the following could be called "pathogens"?

E. All of them can be pathogens, i.e. capable of causing disease in other organisms.\n\nOf course, not all bacteria are pathogens. Most viruses are. Viroids are  plant pathogens.

Non-living\n\nA virus is a submicroscopic obligatory parasitic particle that infects cells in biological organisms. Viruses are "non-living particles" that can only replicate when an organism reproduces the virulent RNA or DNA.

There are other Staphylococci which are non-pathogenic - those having a negative coagulase test for instance.\n\nBeing they are genus Staphyloccus, they will have many characteristics in common.

bacteria, viruses, cyanobacteria or fungi?  or do you mean specific examples

It IS "Pneumonia", and can be caused by a bacterium, usually Streptococcus pneumoniae, also called pneumococcus.\n\nHope that is what you were looking for.

A predator- kills its (animal) prey while or before consuming it.\nA parasite-consumes it's host, usually not killing it.\nA pathogen-produces disease.\n\nExamples:\n\nMosquitoes are parasites, but not pathogens (May carry pathogens).\nMalaria is a parasite and a pathogen, though parasites are usually thought of as larger organisms.\nLions are predators.\n\nAlso, life is not biology.  Usually there are some things that don't fit neatly into a classification.  Life is just too complex, and defies categorization!  That's  what I love about biology.

Hi there !\nIt is a good question !\nTuberculous Bacteria can affect any organ or tissue in the body...! \nWhen I said, "orgain or tissue", I mean it can invade / affect any place where blood supply is available ! It has been found in Brain, skin, Lungs, Heart, Lymphatics, LLiver, Spleen, joints Kidneys, Bones and intestines !\nNails and Hair are NOT considered as "tissues "....or "organs"\nHope this answers your querry ??\n\nBest wishes !

First off jamesmusik84's is completely wrong. Please don't consider any of it. The second answer is along the right path, except I have no idea what the reference to antibiotic is suggesting and some viruses have RNA genomes but many more have DNA genomes. And as far as bacteria go, both RNA and DNA are present inside there cells.\n\nSo, the answer to your question. Let's start this way: Bacteria are small single-celled organisms. Unllike eukaryotic cells (like the ones that make up animals, plants, fungi and many single-celled organisms such as yeasts) which package their genetic material (DNA) in membrane structures called nuclei, bacteria (which are also referred to as prokaryotes) don't have a nucleus. Bacteria also don't have other organelles which are found in eukaryotes, such as endoplasmic reticulum, mitochandria, chloroplasts, golgi bodies, etc. But like eukaryotes, bacteria do have an outer lipid membrane.\n\nSo, you can think of bacteria of little fluid filled sacs. Along with eukaryotic, bacteria are an example of "cells" which are the smallest unit of living things on earth.\n\nViruses, on the other hand, do not have an outer membrane. They don't the capacity to make their own proteins. They don't have the capacity ot replicate or metabolize on their own -- of which bacteria (and eukaryotes) do. It's for this reason that we don't consider viruses "living" things. Viruses have to "infect" a cell -- injecting its genetic material inside -- and use the cell's metabolic machinery to reproduce.\n\nViruses are essentially small protein "capsules" that have a piece of genetic information packaged inside. Because viruses are required to infect a cell to propogate themselves, they are classified as obligate intra-cellular pathogens.\n\nViruses tend to only infect specific cell types. Some infect bacteria. Some infect plants. Others infect animals. The specificity of what a virus can infect is goes beyond whether they can infect bacteria, plants or animals. Usually viruses have to infect a very specific animal, plant or bacteria. And even in the case of viruses that infect animals and plants, not only do the infect specif animals, they are usually limited to a few cell types whithin that animal.\n\nTake HIV for example: to the best of my knowledge HIV only infects humans (i.e. the "H" in HIV -- Human Immunodeficiency Virus). But it doesn't just infect any human cell. HIV only infects white blood cells -- specifically a class of white blood cells called T cells (there are many other "classes" of white blood cells including such things as B cells, NK cells, neutrophils, basophils, eosinophils and macrophages).\n\nI hope this sheds some light on the matter.

is any illness resulting from the consumption of food contaminctious agents include pathogenic bacteria, toxins, viruses, prions or parasites. Such contamination usually arises from improper handling, preparation, or food storage. Good hygiene practices before, during, and after food preparation can reduce the chances of contracting an illness. The action of monitoring food to ensure that it will not cause foodborne illness is known as food safety. Foodborne disease can also be caused by a large variety of toxins that affect the environment. For foodborne illness caused by chemicals, see Food contaminants.

That would be the red blood cells. White blood cells have to do with immunity to illnesses.

Fifth Disease is also called parvo virus - but it's not the same one that dogs get.\n\nYou cannot get parvo virus or fith disease from a dog & a person cannot transmit it to dogs.
