The Kubic FLOTAC microscope (KFM): a new compact digital microscope for helminth egg counts

Area of Science:

• Veterinary Parasitology
• Digital Microscopy
• Public Health Diagnostics

Background:

• Accurate fecal egg count (FEC) is crucial for diagnosing gastrointestinal nematodes (GINs) in livestock.
• Traditional optical microscopy requires specialized laboratory settings and trained personnel.
• Portable and cost-effective diagnostic tools are needed for field applications.

Purpose of the Study:

• To characterize the Kubic FLOTAC microscope (KFM).
• To validate the KFM's performance for FEC of GINs in cattle.
• To compare KFM-based FEC with traditional optical microscopy (OM).

Main Methods:

• The KFM was used with the Mini-FLOTAC technique on 30 cattle fecal samples.
• FEC results from KFM were compared against those obtained using a traditional optical microscope.
• Image quality and agreement between the two methods were assessed.

Main Results:

• The KFM demonstrated substantial agreement with traditional OM for FEC (concordance correlation coefficient = 0.999).
• Discrepancy between KFM and OM was minimal (−0.425 ± 7.370).
• KFM produced images comparable in quality to those from traditional OM.

Conclusions:

• The KFM is a validated, accurate, and efficient tool for FEC in cattle.
• Its portability and cost-effectiveness make it suitable for both field and laboratory use.
• KFM integration with AI software promises enhanced real-time parasitic structure quantification for improved veterinary and public health.
