Introduction A Bio-Incubator is a laboratory device designed to provide a controlled environment of temperature, humidity, and time for the growth and maintenance of microbial cultures, cell lines, and biological reactions. It is an essential tool in microbiology, molecular biology, biotechnology, and clinical diagnostics.By maintaining …
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 …
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 …
Introduction A throat swab Gram stain is a rapid, initial diagnostic test performed on specimens collected from the oropharynx or tonsillar region. It helps to identify bacterial flora, pathogens, and inflammatory response. While culture and molecular methods provide definitive diagnosis, Gram staining offers early guidance …
Introduction Acinetobacter ursingii is a Gram-negative, non-fermentative, opportunistic bacterium belonging to the genus Acinetobacter. It is an uncommon species compared to Acinetobacter baumannii, but it has been increasingly recognized in healthcare-associated infections (HAIs). Reported cases include bacteremia, septicemia, pneumonia, urinary tract infections, and bloodstream infections, …
Introduction Respiratory tract infections are caused by a wide range of pathogens, including viruses, bacteria, and fungi. Conventional diagnostic methods such as culture, microscopy, and antigen detection are time-consuming and often lack sensitivity. Multiplex polymerase chain reaction (PCR) assays, applied directly to respiratory samples (sputum, …
Introduction Ascitic fluid microscopy is a laboratory diagnostic method used to examine peritoneal (ascitic) fluid obtained via paracentesis. It helps in identifying cells, microorganisms, and crystals that provide clues about underlying causes such as infection, malignancy, liver disease, or systemic disorders. Principle The principle of …
Introduction Pleural fluid is the liquid collected from the pleural space between the lung and chest wall. Microscopic examination of pleural fluid plays a key role in identifying the underlying cause of pleural effusion. It helps distinguish between transudates and exudates, detect infectious organisms, malignant …
