Lactococcus garvieae: Introduction, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction Lactococcus garvieae is a Gram-positive, catalase-negative, non-spore-forming coccus, typically arranged in pairs or short chains. It belongs to the lactic acid bacteria group and is well known as a major pathogen in fish (lactococcosis). In humans, it is an emerging opportunistic pathogen, increasingly recognized …
Isolation and Preliminary Identification of Bacterial and Yeast Colonies on Sabouraud Dextrose Agar Using the Wet Mount Technique
Introduction Sabouraud Dextrose Agar (SDA) is a commonly used culture medium in clinical mycology laboratories for the isolation of fungi, particularly yeasts and molds. Due to its acidic pH and high dextrose concentration, SDA favors fungal growth; however, bacteria and yeasts may also grow, especially …
Streptococcus agalactiae (GBS): Introduction, Pathogenicity, Lab Diagnosis, Treatment, and Keynotes
Introduction Streptococcus agalactiae, also known as Group B Streptococcus (GBS), is a Gram-positive, beta-hemolytic coccus arranged in chains. It is a major cause of neonatal sepsis, meningitis, and infections in pregnant women, and an emerging pathogen in immunocompromised adults. GBS commonly colonizes the gastrointestinal and …

It is an essential tool in microbiology, molecular biology, biotechnology, and clinical diagnostics.By maintaining …
Biological Indicator (Bionova BT20) for Autoclave Sterilization Validation:Introduction, Application, and Keynotes
Introduction Bionova BT20 Biological Indicators (BIs) are specialized tools used to verify the efficiency of steam sterilization (autoclaving) in laboratories, hospitals, and industrial settings. Each indicator vial contains a defined population of Geobacillus stearothermophilus spores, known for their high resistance to moist heat. During an …
Bronchoalveolar lavage (BAL) Gram stain: Introduction, Report-Interpretation, Clinical Significance, and Keynotes
Introduction Bronchoalveolar lavage (BAL) is a diagnostic procedure used to collect specimens from the lower respiratory tract, particularly from the alveolar spaces. It is performed by instilling sterile saline into a segment of the lung via a bronchoscope and then aspirating it back. Gram staining …
Direct Microscopy-KOH Smear: Introduction, Uses, and Keynotes
Introduction Direct microscopic examination is one of the most rapid and inexpensive diagnostic methods for detecting fungal elements in clinical specimens. Potassium hydroxide (KOH) smear is a routine technique in mycology that helps visualize fungal structures such as hyphae, yeast cells, and sclerotic bodies directly …
