Study Notes
Respiratory Secretion
- Respiratory secretion analysis can reveal insights into respiratory health.
- Spum (spitting) can be a misleading indicator due to contamination from saliva and mouth microbiota.
- The presence of many squamous epithelial cells in respiratory secretions may suggest oral contamination.
- Bronchoscopy is a procedure that allows for the collection and examination of respiratory secretions.
- Bronchoalveolar lavage is a method used in bronchoscopy to collect fluid for analysis.
- Bronchoalveolar lavage can help identify the presence of microorganisms, such as Pneumocystis, Legionella, and fungi.
GI Culture
- Enzyme immunoassays are used to detect specific antigens in stool samples.
- Shiga toxin can be detected using enzyme immunoassays and indicates the presence of E. coli O157:H7.
- C. difficile toxin detection helps identify C. difficile infection.
- Protozoa parasites like Giardia and Cryptosporidium can be identified using culture methods.
- Viral pathogens like rotavirus, norovirus, and adenovirus can be detected in stool samples.
STDs
- Syphilis is caused by the bacterium Treponema pallidum.
- VDRL and RPR tests are used to screen for non-specific antibodies to syphilis.
- Chlamydia is a bacterial infection difficult to culture in the laboratory.
Respiratory Secretion
- Sputum samples can be misleading due to contamination from saliva
- Sputum samples often contain many squamous epithelial cells
- Bronchoscopy and bronchoalveolar lavage are often performed to collect respiratory samples
- Bronchoalveolar lavage is useful for the detection of Pneumocystis, Legionella, and fungi
GI Culture
- Enzyme immunoassays can be used to detect shiga toxin and C. difficile toxins
- GI cultures can be used to detect protozoan parasites and viral pathogens
STDs
- Syphilis is caused by the pathogen Treponema pallidum
- The VDRL and RPR tests are used to detect non-specific antibodies to syphilis
- Chlamydia is difficult to culture
Respiratory Secretion
- Spum (spitting) is a type of respiratory secretion that is misleading as it can be contaminated with saliva and mouth microbiota.
- Bronchoscopy is a procedure used to obtain respiratory secretions.
- Bronchoalveolar lavage is a technique used during bronchoscopy to collect samples for diagnosis.
- Pneumocystis, Legionella, and fungi are microorganisms that can be identified from respiratory secretions.
Gastrointestinal (GI) Culture
- Enzyme immunoassays are used in GI cultures to detect specific toxins and antigens.
- Shiga toxin and Clostridium difficile toxin are commonly detected in stool samples.
- Protozoa parasites and viral pathogens can also be identified in GI cultures.
Sexually Transmitted Diseases (STDs)
- Syphilis is caused by the bacteria Treponema pallidum.
- VDRL and RPR tests are used to detect non-specific antibodies against Treponema pallidum.
- Chlamydia is a difficult bacteria to culture in the laboratory.
Respiratory Secretions
- Spum refers to spitting, and is often used to describe the expulsion of phlegm.
- Analyzing respiratory secretions requires careful consideration, as contamination from saliva and mouth microbiota can be misleading.
- The presence of many squamous epithelial cells suggests contamination from the mouth.
- Bronchoscopy is a procedure that allows for the direct visualization and sampling of the airways.
- Bronchoalveolar lavage (BAL) is a procedure used to collect fluid from the alveoli of the lungs, which can be used to diagnose various respiratory infections.
-
BAL can be helpful in identifying:
- Pneumocystis
- Legionella
- Fungi
GI Culture
- Enzyme immunoassays are commonly used to detect the presence of toxins in the digestive system.
- Shiga toxin is a toxin produced by certain strains of E. coli, which can cause severe diarrhea and kidney damage.
- C. difficile toxin is a toxin produced by Clostridium difficile bacteria, which can cause antibiotic-associated diarrhea and colitis.
- Culture of the digestive system can also identify various protozoa parasites and viral pathogens.
Sexually Transmitted Diseases (STDs)
- Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum.
- VDRL (Venereal Disease Research Laboratory) and RPR (Rapid Plasma Reagin) tests are non-specific antibody tests used to screen for syphilis.
- Chlamydia is another common STD, which is difficult to culture in the lab.
Respiratory Secretion
- Spum (spitting) can be misleading due to contamination of saliva and mouth microbiota
- Squamous epithelial cells can be found in respiratory secretions
- Bronchoscopy and bronchoalveolar lavage can be used to collect respiratory secretions
- Bronchoalveolar lavage is specifically useful for detecting:
- Pneumocystis
- Legionella
- Fungi
GI Culture
- Enzyme immunoassays are used for detecting toxins in GI cultures
- Shiga toxin and C. difficile toxin can be detected by immunoassays
- Protozoa parasites and viral pathogens can be identified in GI cultures
STDs
- Syphilis is caused by the bacteria Treponema pallidum
- VDRL and RPR tests detect non-specific antibodies for syphilis
- Chlamydia is difficult to culture in a lab
