Assessment of the Performance of Indirect Immunofluorescence Assay for Chagas Disease in Dogs Using a Reference Panel of Four Chimeric Proteins

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
We evaluated the performance of an indirect immunofluorescence (IIF) assay for detecting anti‐Trypanosoma cruzi IgG in dogs using four chimeric IBMP antigens and latent class analysis. The IIF assay showed suboptimal sensitivity and overall accuracy compared to ELISA and LCA‐based methods.

Recombinant LPG3 Protein From Leishmania chagasi as an Antigen for the Diagnosis of Canine Visceral Leishmaniasis

Tropical Medicine &International Health, Volume 31, Issue 8, Page 1057-1065, August 2026.
ABSTRACT Visceral leishmaniasis (VL) is a human neglected tropical disease in which dogs participate as reservoirs of the etiological agent Leishmania chagasi. The identification of infected dogs is important to the control of VL, and recombinant proteins are strong antigen candidates for canine visceral leishmaniasis (CVL) serodiagnosis. In this work,

Schistosoma mansoni in a low-prevalence area in Brazil: the importance of additional methods for the diagnosis of hard-to-detect individual carriers by low-cost immunological assays

Memorias do Instituto Oswaldo Cruz, 2013
Schistosomiasis diagnosis is based on the detection of eggs in the faeces, which is laborious and lacks sensitivity, especially for patients with a low parasite burden.

Diagnosis of Mucormycosis: Current Situation, Challenges and Future Prospects

Mycoses, Volume 69, Issue 4, April 2026.
ABSTRACT Mucormycosis, an aggressive fungal infection caused by members of the order Mucorales, progresses rapidly and is associated with high mortality, particularly in immunocompromised hosts such as patients with uncontrolled diabetes, transplant recipients or those with COVID‐19‐associated immunosuppression. Early diagnosis remains challenging with
