Which type of pneumonia is the most serious?

Hospital-acquired pneumonia (HAP) This type of bacterial pneumonia is acquired during a hospital stay. It can be more serious than other types, as the bacteria involved may be more resistant to antibiotics.

Which of the following microorganisms is the causative agent of typical pneumonia?

The typical bacteria which cause pneumonia are Streptococcus pneumoniae, Staphylococcus aureus, Group A Streptococcus, Klebsiella pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, anaerobes, and gram-negative organisms.

What causes bronchopneumonia?

It occurs when viruses, bacteria, or fungi cause inflammation and infection in the alveoli (tiny air sacs) in the lungs. Bronchopneumonia is a type of pneumonia that causes inflammation in the alveoli. Someone with bronchopneumonia may have trouble breathing because their airways are constricted.

Which viral agent is responsible for the most common community acquired pneumonia quizlet?

Rhinovirus is the most common viral pathogen. Haemophilus influenzae, Streptococcus pneumoniae, and Moraxella catarrhalis make up the majority of community-acquired bacterial pathogens.

What deficiency causes fungal infections?

CARD9 deficiency, an autosomal recessive disorder, differs from many other genetic immune disorders that cause fungal infections. Most genetic immune disorders cause either CMC or systemic candidiasis, but people with CARD9 deficiency experience both CMC and systemic candidiasis.

Which microorganism is known to cause an opportunistic infection in someone who has a compromised immune system?

Pneumocystis pneumonia (PCP) PCP is a lung infection caused by the fungus Pneumocystis jirovecii. PCP occurs in people with weakened immune systems.

Which of the following microorganisms is the causative agent of typical pneumonia quizlet?

The most common causative agent of bacterial pneumonia is Streptococcus pneumoniae.

What microbes cause pneumonia?

Viruses, bacteria, and fungi can all cause pneumonia. In the United States, common causes of viral pneumonia are influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (the virus that causes COVID-19). A common cause of bacterial pneumonia is Streptococcus pneumoniae (pneumococcus).

Which lobe is mostly affected by pneumonia?

Upper, middle and lower lobe pneumonia Depending on which lung lobe is affected, the pneumonia is referred to as upper, middle or lower lobe pneumonia. If there are several multi-lobe focal inflammations in the lungs, the term focal pneumonia is used.

What are symptoms of systemic fungal infection?

Symptoms. Common symptoms of candidemia (Candida infection of the bloodstream) include fever and chills that do not improve with antibiotics . Candidemia can cause septic shock and therefore may include symptoms such as low blood pressure, fast heart rate, and rapid breathing.

Which of the following best describes an opportunistic infection?

An opportunistic infection is an infection caused by bacterial, viral, fungal, or protozoan pathogens that take advantage of a host with a weakened immune system or an altered microbiota. Many of these pathogens do not cause disease in a healthy host that has a normal immune system. … Most common OI assoc.

Is bacterial or viral pneumonia worse?

Both Bacteria and Viruses Can Cause Pneumonia, But One Is Much Worse for the Heart. CHICAGO — Pneumonia caused by bacterial infections poses a much greater threat to the heart than pneumonia caused by viral infections, a new study suggests.

Which of the following is an example of an opportunistic fungal infection?

Opportunistic fungal infections Causes of immunocompromise include AIDS, azotemia, diabetes mellitus, lymphoma, leukemia, other hematologic cancers, burns, and therapy with corticosteroids, immunosuppressants, or antimetabolites.

What features of the respiratory system protect us from infection?

The main way the respiratory system protects itself is called the mucociliary escalator. From the nose through the bronchi, the respiratory tract is covered in the epithelium that contains mucus-secreting goblet cells. The mucus traps particles and pathogens in the incoming air.

Which of the following is a symptom of brucellosis?

Early symptoms of brucellosis include fever, fatigue, sweating, pain in the muscles and joints, pain in the back, and/or loss of appetite; over time, fevers may become recurrent, organ damage may occur (organ swelling), and skin changes such as rashes and/or micro-abscesses may form.

What features of the fungus are used to diagnose an infection?

Doctors usually diagnose the infection by scraping scaling skin off of a person and inspecting it under a microscope for evidence of any fungus. There are a few different fungi that can cause athlete’s foot. The infection may behave differently depending on the specific fungus that is infecting the skin.

What’s the difference between bacterial and viral pneumonia?

Treatment is the biggest difference between bacterial and viral pneumonia. Bacterial pneumonia is treated with antibiotic therapy, while viral pneumonia will usually get better on its own. In some cases, viral pneumonia can lead to a secondary bacterial pneumonia.

Which organism causes a disease characterized by the catarrhal paroxysmal and convalescent stages?

bacteria Bordetella pertussisPertussis is a highly contagious acute respiratory disease caused by the bacteria Bordetella pertussis. This disease has 3 stages: catarrhal, paroxysmal, and convalescent.

Which one of the following is an opportunistic pathogen?

Examples of opportunistic pathogens are: Candida albicans – a causal agent of opportunistic oral and genital infections in human. Staphylococcus aureus – occur as commensal on human skin but may cause staph infections.

How can opportunistic pathogens cause infections?

An opportunistic infection is an infection caused by pathogens (bacteria, viruses, fungi, or protozoa) that take advantage of an opportunity not normally available, such as a host with a weakened immune system, an altered microbiota (such as a disrupted gut microbiota), or breached integumentary barriers.
