Abstract:

Background and objective: Implementation of standard methods for accurate detection of bacteria, correct antibiotic susceptibility testing and effective treatment of bacterial infections play important roles in development of public health and prevention of drug resistance. This study aimed to detect bacteria using standard methods and compare the results with the results obtained in teaching hospitals&rsquo; laboratories. Methods: Positive culture plates containing bacteria isolated from patients in hospital laboratories in city of Sari were transferred to microbiology laboratory of Faculty of Medicine at Mazandaran University of Medical Sciences, after determining the genus and species of bacteria and antibiotic susceptibility testing of the isolates. The samples were re-examined based on standard protocols, and antibiotic susceptibility testing was done using the Kirby-Bauer method. Results: Of 101 patients, 20% of bacteria and 22.5% of antibiotic sensitivity results reported by the hospital laboratories were incorrect. There were significant differences between the two study groups in terms of bacterial species detection and sensitivity to some drugs (P<0.05). Conclusion: In the present study, lack of implementation of internal quality control programs in some hospital laboratories and lack of proper monitoring by regulatory authorities in different departments of the hospital have caused 20% false-detection results in hospital reports. Inconsistency in results of laboratories, false antibiograms and subsequent false laboratory reports cause drug resistance in some patients. This indicates the necessity of continuous training in the field of Microbiology and implementation of standard protocols and methods for detection of bacterial species and antibiotic susceptibility testing.

Laboratory diagnosis of fungal infections

Selection of appropriate specimens for culture and microscopic examination is based on the results of clinical and radiographic examination and consideration of the most likely fungal pathogen that may cause such an infection. Specimens should be collected under aseptic conditions or after appropriate cleaning and decontamination of the collection site and rapidly transported to the clinical my...

Diagnosis of Tuberculosis: Novel Laboratory Methods

Despite advances in medical sciences in recent years, tuberculosis remains a worldwide health problem. Although there are many laboratory methods to accelerate the diagnosis, a delay in the definitive diagnosis of the disease is still a major clinical problem. Due to the slow growth of the causative agent, (Mycobacterium tuberculosis), isolation, identification, and other clinically important m...
