streptococus pneumonia
A pathogen.

The hepatitis A virus (HAV) is the parasite that causes hepatitis A infection. It is primarily transmitted through ingestion of contaminated food or water.
Trichomoniasis is an infection caused by the parasite Trichomonas vaginalis, not a disease. It is a common sexually transmitted infection (STI) that can cause symptoms such as vaginal discharge and itching. Treatment typically involves antibiotics.
The pathogenic protozoan that causes malaria, Plasmodium, is primarily transmitted to humans through the bites of infected female Anopheles mosquitoes. When an infected mosquito bites a person, it injects Plasmodium parasites into their bloodstream, where they then travel to the liver and red blood cells to multiply and cause infection.
In children under two, the virus causes a serious lower respiratory infection in the lungs. In older children and healthy adults, it causes a mild upper respiratory infection
A pathogen.
contagion
Dusty conditions, a lungworm infestation or a respiratory infection.
It can be anything from a cold, allergies to upper respiratory infection.
Causes of minimal Koch's infection are respiratory infections. Koch's bacillus is the pathogen which causes tuberculosis which is seen on a chest x-ray as an infiltrate, or poorly defined space.
The most common cause of death was infection. Predisposing factors for infection included the underlying disease. Also contributing to death are the following extranadal sites of involvement: respiratory track, bone marrow, liver, kidney and gastrointestinal track.
Birds don't get or transmit chlamydia trachomatis, the germ that causes the sexually transmitted infection. Birds may transmit chlamydia psittaci, which is not sexually transmitted.
The hepatitis A virus (HAV) is the parasite that causes hepatitis A infection. It is primarily transmitted through ingestion of contaminated food or water.
Trichinella spiralis, a parasitic roundworm, can be transmitted to humans by consuming undercooked or contaminated pork. This can lead to trichinellosis, a parasitic disease, with symptoms including gastrointestinal issues, muscle pain, and fever. Cooking pork to proper temperatures can effectively kill the parasite and prevent infection.
Possible upper respiratory infection.
bartonellosis refers exclusively to the disease caused by B. bacilliformis.Bartonellosis is transmitted by the nocturnal sandfly and arises from infection with B. bacilliformis
