THINK BEYOND A PETRI DISH ?
Dr.T.V.Rao MD All our competence of the Diagnostic Microbiology is many times limited to a Petri dish as we have limited facilities, and see many struggles and in fights in the departments are limited to a few expressions on Petri dish , certainly it is all not true as anything which grows on petri dish may not all useful has many inputs some good and many uncontrolled factors , Never to forget majority of specimens we get in laboratories may be infected with Bacteria, parasitic fungal and viral etiology , which is not imagined many times, today many see the request and discard the specimens without futures thinking , and always tell the friends in the department keep the specimen in the cold temperature at least till the requested report is dispatched, when we are confused with the results arising out of limited testing’s in the laboratory, this continues to my vison THINK BEYOND A PETRI DISH and many times we do not fully understand the true diagnostic value of a clinical specimen, I have seen people start showing their egos without knowing many realities of the specimens we get in the laboratories, I wish it is time TO expand our thinking beyond our limited knowledge, and grow better in career , Still for any wise in the word INFECTION is ill understood word as manifestations of infections are very wide, and manifestations of an infection depend on many factors, including the site of acquisition or entry of the microorganism; organ or system tropisms of the microorganism; microbial virulence; the age, sex, and immunologic status of the patient; underlying diseases or conditions; and the presence of implanted prosthetic devices or materials. Think about a simple urine culture it is in reality more difficult and complex when we see the realities one dose of Antibiotic certainly alter the cfu units, it just means no dictum's to be depended, absolutely, No specimen has any value without true clinical inputs as requested by the Microbiologists staff of a clinical microbiology laboratory should be qualified to advise the physician as well as process specimens. The physician should supply salient information about the patient, such as age and sex, tentative diagnosis or details of the clinical syndrome, date of onset, significant exposures, prior antibiotic therapy, immunologic status, and underlying conditions. It is truly awful many physicians fish the diagnosis from ill understood Science of Microbiology. For a student started his career in diagnostic Microbiology, the microbiology specimen is a product of many facts Physicians and Microbiologists must also consider that the composition of microbial species on the skin and mucous membranes may be altered by disease, administration of antibiotics, endotracheal or gastric intubation, and the hospital environment. For example, potentially pathogenic bacteria can often be cultured from the pharynx of seriously ill, debilitated patients in the intensive care unit, but may not cause infection, the clinical Microbiologists should certainly KNOW when delivering the reports from Intestine and Critical care units, the recent studies enlighten patients after few days of admission to hospitals will be colonized with MDR strains yet not invading, and unwise reports of us without rationalism make the physicians to use last generation of antibiotics to date and certainly unwise treatment are counterproductive. The clinical microbiologists should be proactive to participate in decisions regarding the micro-biologic diagnostic studies to be performed, the type and timing of specimens to be collected, and the conditions for their transportation and storage he clinical microbiology laboratory, whenever appropriate, should provide an interpretation, I feel certainly growing beyond a Petri dish is the true need of the Hour?
MICROBES ARE LIKE OUR FRIENDS HOWEVER STILL WE HAVE NOT PERFECTED TO KNOW USEFUL FROM DANGEROUS ONES
