Political action committee. In the United States, a political action committee (PAC) is a type of organization that pools campaign contributions from members and donates those funds to campaign for or against candidates, ballot initiatives, or legislation. The legal term PAC has been created in pursuit of campaign finance reform in the United States. This term is quite specific to all activities of campaign finance in the United States. Democracies of other countries use different terms for the units of campaign spending or spending on political competition (see political finance).
S pneumoniae is the most common cause of community-acquired pneumonia (CAP), bacterial meningitis, bacteremia, and otitis media, as well as an important cause of sinusitis, septic arthritis, osteomyelitis, peritonitis, and endocarditis and an infrequent cause of other less common diseases.See the image below. pneumoniae is the most common cause of community-acquired pneumonia (CAP), bacterial meningitis, bacteremia, and otitis media, as well as an important cause of sinusitis, septic arthritis, osteomyelitis, peritonitis, and endocarditis and an infrequent cause of other less common diseases.

Many different germs can cause pneumonia, but there are five main causes: bacteria, viruses, mycoplasma (a type of bacteria that is resistant to penicillin), other infectious agents, such as fungi, and various chemicals. If you have viral pneumonia, you also are at risk of getting bacterial pneumonia. The main cause of pneumonia is the bacteria streptococcus pneumoniae. Professor Brian Duerden CBE, the chief micro-biologist at the Department of Health, said the bacteria can also cause or lead to numerous other invasive infections. It can cause other chest infections in old people as well as pneumonia, he said. It can affect young children when it can get into their blood streams. It can cause septicemia. It is also the most important cause of meningitis in very young children. In some people it can get into the sinuses and into the middle ear and cause further infection. Understanding the cause of pneumonia is important because pneumonia treatment depends on its cause.
