The vast majority of bacteria are harmless to us humans, and a great number of them are actually beneficial to us. There are, however, a smaller number that are actually harmful. Most of these cause contagious diseases, while some of the more virulent are infectious.
A few like tuberculosis, syphilis, and chlamydia, are infectious, which means that they are spread by intimate contact. It is not so much the type of bacteria that makes it infectious, but rather the transmission route. For a pathogen to be infectious it is spread through contact with body fluids, in particular blood, semen, vaginal secretion, breast milk, and sometimes saliva.
Bacteria, some fungi and viruses
A non-communicable disease or NCD is a disease which is not infectious, therefore it does not have any method of transmission to other organisms.
if the disease is caude by a microorganism, this is called ( infection
Infectious disease
Infectious diseases involve a causative organism, from groups such as bacteria, viruses, fungi, and such. Noninfectious diseases involve causes other than specific infectious organisms.
The Centers for Disease Control and Prevention (CDC) is the government agency responsible for tracking infectious diseases in the US. They monitor and respond to disease outbreaks, conduct research, and provide guidance to prevent the spread of infections.
Prostate cancer is not considered an infectious disease. Unlike infections caused by bacteria, viruses, or other pathogens that can be transmitted from person to person, prostate cancer is a type of cancer that develops within the prostate gland due to the uncontrolled growth of abnormal cells. While infectious agents such as viruses or bacteria have been implicated in the development of some cancers, there is currently no strong evidence to suggest that prostate cancer is caused by an infectious agent. The majority of prostate cancers are thought to result from a combination of genetic, environmental, and lifestyle factors, rather than infectious causes. However, certain infections and inflammation of the prostate gland, such as chronic prostatitis or sexually transmitted infections, may be associated with an increased risk of developing prostate cancer in some cases. Chronic inflammation in the prostate gland has been hypothesized to contribute to the development and progression of prostate cancer, although the exact mechanisms are not fully understood. Overall, while infections and inflammation may play a role in some cases, prostate cancer is primarily considered a non-infectious disease driven by genetic, hormonal, and environmental factors. Early detection through regular screening and consultation with a healthcare professional remain critical for managing prostate cancer risk and detecting the disease in its early stages.

Pellagra is not an infectious disease. Pellagra is a nutritional deficiency disease.
The Center for Disease Control and Prevention is responsible for the protection of persons and public safety by controlling diseases which can be harmful and infectious to others. They also research non infectious diseases such as diabetes.
