Most of the bacteria are pathogens sometimes they may result in death but majority of them are necessary to human health. Some of the bacteria are infectious but people not show harmful effects such type of people are called as carriers. Infectious disease Typhoid Mary is an example for such disease. Infectious disease bacteria caused by a bacteria and a type of microbe which include viruses as well as fungi. When harmful bacteria get enter into sterile areas through inhalation it resulting in symptoms of bacterial disease.

Structure of bacteria which causes infectious deceases:

Pathogens Transmission of infectious disease bacteria

Pathogens of infectious disease bacteria:

Tetanus, typhoid fever, diphtheria, syphilis, cholera, foodborne illness, leprosy and tuberculosis cause infections and they are the major cause of human death and disease. For example staphylococcus can cause skin infections like pneumonia, meningitis and also overwhelming sepsis. In agriculture also bacterial diseases are important because they cause leaf spot, fire blight and wilts in plants. In animals bacteria causes Johne’s ...
... disease, mastitis, salmonella and anthrax.

Transmission of Infectious disease bacteria:

Infectious disease caused by bacteria is transmitted involves vectors and also through different mechanisms. Meningitis and some of the respiratory diseases spread by sneezing, coughing and even by talking. Ingestion of the contaminated food water leads to gastrointestinal diseases. Some of the infectious diseases spread directly through skin.

Symptoms and Prevention of Infectious disease bacteria

Symptoms of Infectious disease bacteria:

Depending on the type of bacterial infection and the area of the body infected symptoms varies. Fever is the classic symptom of the bacterial disease. Any area of the body may affected by the bacterial symptoms. Symptoms include headache, stiff neck, chest pain, joint pain, diarrhea, abdominal pain also abscesses. Complications of bacterial diseases are sepsis, kidney failure, toxic shock syndrome, permanent neurological syndrome finally death.

Prevention of Infectious disease bacteria:

For the prevention of infectious disease we have to recognize the different characteristics of diseases. Slowly by attacking their immune system Human deficiency syndrome kills the victims. So victims transmit the virus to other individuals.Infectious Disease is the abnormality in the normal functioning of an organ, or part of the body of an organism caused by the external agents like pathological microorganisms .These pathological agents are called Infectious disease agents. The infectious disease is shown by some external signs these are called as symptoms. By analyzing these symptoms one can know the type of infectious diseases and also the disease causing agents. Some of the infectious disease agents are pathogenic viruses, bacteria’s, fungi, protozoa, multicellular parasites, and the prions (aberrant proteins). These agents can attack both animals and plants and are able to cause diseases. Infectious disease is the result of interaction between the infectious disease agents and the immune or defense system of the host they attack. Thus the appearance and the severity of the disease are mainly depending on the ability of the pathogen to infect the host as well as the ability of the host to resist the pathogenic agents.

Classification of infectious disease agents

According to the status of host defenses they are classified as primary pathogens or opportunistic pathogens.

Primary pathogens are the microbes that cause disease mainly in humans and are highly virulent microorganisms. These cause diseases as result of their activity in healthy organ or tissues of the host body .These pathogens can cause serious disease in host and this severity of the disease is a necessary consequence of their need to reproduce (multiply) and spread.

Opportunistic pathogens are the microorganisms which cause an infectious disease in host along with the depressed resistance. Opportunistic disease may be caused by the pathogens which are ordinarily in the host body, such as pathogenic fungi or bacteria in the upper respiratory tract or in the gastrointestinal tract. They may also result from the environment as a result of traumatic introduction or from the microbes acquired from other host. An opportunistic disease may occur as a result of genetic defect, exposure to immunosuppressive chemicals, antimicrobial drugs or to ionizing radiation or as a result of an infectious disease with immunosuppressive activity (eg: measles, malaria or HIV disease).

The disease caused by the infectious disease agent can be transmitted from infected individual to a healthy person. Transmission of disease can occur by several means which are i) droplet contact that includes coughing or sneezing on another person ii) direct physical contact by touching an infected person iii) vector borne transmission includes transmission carried by insects or other animals iv) if the microorganism can remain in the air for long periods then there can be airborne transmission v) fecal-oral transmission is usually from contaminated food or water sources.vi)Indirect contact usually by touching soil contamination or a contaminated surface.
