Introduction of Microbiology Reporting Templates
Microbiology reporting templates are designed to streamline the process of documenting findings, thereby reducing time and effort for users. Furthermore, these templates provide a structured framework, which ensures both consistency and accuracy across reports. Specifically, they cover various branches of microbiology, including bacteriology, mycology, parasitology, virology, and immunology, making them comprehensive tools for laboratory and clinical applications. Moreover, they help standardize reporting formats, thereby eliminating the need for repetitive formatting and enabling professionals to focus more on critical analysis.
In addition, the templates are highly flexible and can be tailored to meet specific requirements, thus making them suitable for a wide range of scenarios. Additionally, they ensure that all essential information is systematically documented, thereby minimizing the chances of errors. Moreover, by promoting clear communication between microbiologists, clinicians, and other stakeholders, they significantly improve the overall efficiency of workflows. For new professionals, these templates also act as practical training aids, introducing them to standard reporting practices. Ultimately, microbiology reporting templates enhance clarity, consistency, and efficiency in microbiological documentation.

Clinical Notes
- Please correlate clinically.
- Please correlate these findings with the patient’s clinical presentation.
- Further incubation is in process. The result will be updated, and the client will be informed of any changes in the final report.
- The remaining antibiotics are currently undergoing antimicrobial susceptibility testing (AST).
- Doxycycline is currently undergoing antimicrobial susceptibility testing (AST).
- Please provide a fresh sample due to the indeterminate result of rifampicin resistance (rpo B gene) for repeating the test.
- The rpoB gene, which is suggestive of Rifampicin resistance, could not be determined.
- Contamination, please repeat the mid-stream urine (MSU) sample.
- The load of organisms in the specimen is not mentioned in the final report due to receiving pure isolated heavy growth on a culture plate for identification of the isolate and to check the antibiogram pattern.
- The load of organisms in the specimen is not specified, as it was received for bacterial growth plate identification and antimicrobial susceptibility testing of the isolate.
- Sputum for Gram Stain
Pus cells<25/LPF
Epithelial cells>10/LPF
- Organism: Normal Upper Respiratory Tract Flora Seen
- The patient’s sample was tested twice. The initial GeneXpert result showed that an MTB trace was detected, with Rifampicin resistance indeterminate. Upon follow-up, the patient remained asymptomatic. A repeat test was performed, which revealed MTB detected (low) and Rifampicin resistance not detected, as shown in this final report.
- The above test assay analyses the N gene, ORF1ab gene, and E gene of the SARS-CoV-2 virus.
- The load of the organism is not mentioned in the report due to receiving growth on an MHA plate rather than a specimen for identification and antibiogram assay of the sent isolate.
- A repeat midstream urine specimen was collected following a prior mixed flora culture. This specimen again demonstrated mixed growth and was processed for organism identification and antimicrobial susceptibility testing (AST).
- Note: Serratia-related-
Cefalotin/cephalothin was the standard before 2014; cefazolin is the current CLSI-recommended surrogate for testing 1st-generation cephalosporin susceptibility in Enterobacterales causing UTIs.
In our VITEK 2compact is still Cefalotin and it was not determined, maybe due to intrinsic resistance ( the isolate posing an inducible, chromosomal AmpC β-lactamase), or organism-specific resistance mechanisms, or regulatory shifts in clinical guidelines
Serratia is part of the Enterobacteriaceae family, though some newer classifications place it in the related Yersiniaceae family within the order Enterobacterales.
-faint pink colonies (Slow or Delayed lactose Fermenter-LF colony)-
Serratia isolates are considered intrinsically resistant to ampicillin and first-generation cephalosporins. (Ref. https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/serratia-liquefaciens)Antibiotics Serratia is Intrinsically Resistant To:
Penicillins: Ampicillin and other penicillins.
Cephalosporins: Especially first and second-generation ones (e.g., cephalothin).
Macrolides.
Tetracyclines (though resistance patterns vary).
Nitrofurantoin.
Cationic Antimicrobial Peptides (CAPs).
Polymyxin B.
Antibiotics Often Effective (But Susceptibility Testing is Crucial):
Aminoglycosides: Amikacin, gentamicin, tobramycin (resistance is increasing).
Quinolones: Ciprofloxacin, nalidixic acid (highly active against most strains).
Beta-lactam/beta-lactamase Inhibitor Combinations: Piperacillin-tazobactam (good empirical choice).
Carbapenems: Meropenem (effective, but carbapenem resistance is a growing concern).
Trimethoprim-Sulfamethoxazole (TMP-SMX).
Chloramphenicol.
