Species: Canine | Classification: Lab Tests
- Bacterial infections can cause severe diarrhea, especially in young animals.
- Fecal culture can demonstrate these bacteria and with sensitivity testing suggest effective antimicrobial therapy.
Source of Test Material
- Rectal sample or freshly voided feces.
- Standard hygiene.
- Transport medium swabs ( rectal swab) or sterile container (feces or diarrhea sample).
- Refrigerate if sample is not being posted/processed immediately.
- Package according to postal regulations Transportation of diagnostic specimen.
- Growth on selective and nonselective media with identification of significant colonies.
- Widely available.
Technique (Intrinsic) Limitations
- May have false negative cultures when pathogens present.
- It is important to carry out at least two samplings as pathogens are excreted intermittently.
Technician (Extrinsic) Limitations
- Requires special knowledge and techniques for accurate isolation and identification of potential pathogens.
Normal (Reference) Values
Errors and Artifacts
- False negative culture results: if treatment with antimicrobials before sampling.
