There thousands that are passed from one person to another. Another name for them is infectious diseases.
A person with anthrax isn't considered contagious so if you get anthrax then no you are not contagious.
Lets just look at the plague bacillus as most microbes spread in different ways.Signs and symptoms of the plague: elevated fever, flulike symptoms at first, buboes, which were orange sized, septic shock, cardiovascular collapse.There are two forms of bubonic plague: the bubonic form (cardiovascular) and the pneumonic form (lungs and respiratory tract). The pneumonic was nearly 100% fatal and passed like a cold is. The bubonic form entered the blood and travel into the lymph system. The nodes tried to produce many white cells to fight it off and many times won.
A virus can be contagious by contact or being in the same atmosphere of a sick person.
The infections do not become more or less contagious by resistance to antibiotics. Only thing becomes difficult is how to treat the disease. You kill a person and that person is dead. You kill an antibiotic and millions are dead.

Same way you can catch a cold : Having contact with a person that has pneumonia by touching, kissing, eating or drinking after them etc. You can also catch it if your not covered in the winter.
The symptoms of secondary pneumonic plague are a high fever, a cough that brings up bloody sputum, breathing problems, and respiratory failure. This type of plague affects a person's lungs.
There were two forms of plague, one Bubonic and the other Pneumonic. Pneumonic was not currable.
Yes
How do you get it? You get primary pneumonic plague when you inhale plague bacteria from an infected person or animal. You usually have to be in direct or close contact with the ill person or animal. You get secondary pneumonic plague if you have untreated bubonic or septicemic plague that spreads to your lungs. What are the symptoms? Symptoms usually develop within 1 to 3 days after you are exposed to airborne droplets of plague bacteria. Pneumonia begins quickly, with shortness of breath, chest pain, cough, and sometimes bloody or watery sputum. Other symptoms include fever, headache, and weakness. Is it contagious?Pneumonic plague is contagious. If someone has pneumonic plague and coughs, droplets containing Y. pestis bacteria from their lungs are released into the air. An uninfected person can then develop pneumonic plague by breathing in those droplets. Y. pestis is found in animals throughout the world, most commonly in rats but occasionally in other wild animals, such as prairie dogs. Most cases of human plague are caused by bites of infected animals or the infected fleas that feed on them. In almost all cases, only the pneumonic form of plague (see Forms of Plague) can be passed from person to person. A health care provider can diagnose plague by doing laboratory tests on blood or sputum, or on fluid from a lymph node. When plague is suspected and diagnosed early, a health care provider can prescribe specific antibiotics (generally streptomycin or gentamycin). Certain other antibiotics are also effective. Left untreated, bubonic plague bacteria can quickly multiply in the bloodstream, causing septicemic plague, or even progress to the lungs, causing pneumonic plague.
In addition to the bubonic plague, there are two other different diseases caused by the same organism, called the septicemic plague and the pneumonic plague. The bubonic plague is spread by rats and fleas; a person gets it by being bitten by an infected flea. The septicemic form is the same disease, except that it has spread into a person's blood stream, where it progresses more rapidly and is more likely to be lethal. If the plague gets into a person's lungs, then the form is the pneumonic plague, and it can be spread in the droplets in the air when that person coughs; another person can catch the pneumonic plague by breathing the air.

I dont think so. Yes. In the early stages, it's called bubonic plague and is spread primarily by insects. In the case of the Black Death in Europe, it was spread by fleas which traveled from place to place on rats. The later stage is called pneumonic plague and is extremely contagious, spread through coughing.
yes if someone who had the black death breathed on you or you breathed it in the you would have the pneumonic plague
