FEATURES OF THE VITEK 2 AUTOMATED COMPACT SYSTEM FOR BACTERIAL IDENTIFICATION AND ANTIMICROBIAL SUSCEPTIBILITY TEST (AST)

Helping the physician select the best treatment at a much faster pace based on the right microbial identification and antimicrobial susceptibility test is crucial in any infectious disease management and patient total wellbeing. Clinical microbiology laboratories are the first lines of defense for the detection of antibiotic resistance from clinical pathogens and/or samples. And the […]

PCR TECHNIQUE

DrChika

PCR is the acronym for “polymerase chain reaction”. Polymerase chain reaction is the molecular biology technique that is used to amplify or copy specific gene sequences or nucleotides of a DNA molecule or gene. It was invented by Kary Mullis and his colleagues in the early 1980s; and PCR technique is the most widely used

ENZYMES USED IN MOLECULAR BIOLOGY TECHNIQUES

DrChika

Restriction endonucleases are DNA cutting enzymes specifically found and isolated from bacteria; and which nick specific sites on a nucleotide sequence known as restriction sites. Restriction sites are the different sites on a DNA molecule that is nicked by a particular restriction enzyme. Several types of restriction enzymes exist, and they are primarily sourced from

SPUTUM CULTURE TECHNIQUE

DrChika

Sputum culture is often recommended in the diagnoses of lower respiratory tract infection (e.g. bacterial pneumonia and pulmonary tuberculosis). Lower respiratory tract infections (LRTIs) are infections/diseases that occur below the voice box (larynx) i.e. in the bronchi and trachea. In this case, an induced or expectorated sputum specimen and not saliva is requested and obtained

URINE CULTURE TECHNIQUE

DrChika

Urine culture is performed in order to specifically identify organisms that may be causing a urinary tract infection (UTI). Urine in the bladder is often sterile as it is free from microorganisms. It becomes inundated with microorganisms (especially those of the normal micro-flora) when it leaves the bladder. UTI is very common in patients that

BLOOD CULTURE TECHNIQUE

DrChika

Blood culture is the most important diagnostic method for detecting and diagnosing bacteraemia (presence of bacteria in blood) and fungimia (i.e. presence of pathogenic fungi in blood) in the clinical microbiology laboratory. Blood specimen required for blood culture technique should be collected from the patient prior to antibiotic therapy in order to increase the sensitivity

STOOL CULTURE TECHNIQUE

DrChika

Stool culture is demanded in the bacteriology laboratory as method for detecting and diagnosing enteric bacterial infections (i.e. infections caused by pathogens in the Enterobacteriaceae family e.g. Salmonella species and Shigella species) that lead to enteric fever, diarrhea and dysentery. Stool culture can also be requested when patients present with other gastrointestinal infections such as

LABORATORY DIAGNOSIS OF FUNGAL INFECTIONS/DISEASES

DrChika

The laboratory diagnosis of fungal infection is mainly based on microscopy and cultural techniques. Several culture media exist for the selective isolation of pathogenic fungi from clinically important specimens. The choice of culture media to be used is largely dependent on the type of mycoses and the category of samples to be analyzed amongst other

CLASSIFICATION OF MICROORGANISMS BASED ON HAZARDS AND LABORATORY

DrChika

Pathogenic microorganisms inclusive of viruses, bacteria, and fungi portends health challenges to the general public and healthcare workers or laboratory personnel’s working with these organisms if the proper precautionary measures are not followed in the handling of these microbes. The extensive use of these organisms in research settings or hospital laboratories should be done within

TYPES OF MICROSCOPES

DrChika

There abound several numbers of microscopes that can be used by a microscopist to view specimens or samples and microorganisms in the laboratory. The choice of the microscope to be used is usually dependent on the task to be performed by the user and, on the type of specimen or microorganism to be investigated. Normally,
