Geoepidemiology, seroprevalence and factors associated with Toxoplasma gondii infection in domicilied cats from Paraíba (Brazil)

Parasite
Toxoplasma gondii is a parasite responsible for toxoplasmosis, an emerging and often neglected zoonosis in South America, particularly Brazil. Felines, the only definitive hosts, excrete oocysts in their feces, potentially infecting all homeotherms ...

Reliability of serological methods for detection of leishmaniasis in portuguese domestic and wild reservoirs

Memorias do Instituto Oswaldo Cruz, 1996
A direct agglutination test (DAT) and an immunofluorescence technique (IFAT) were compared for detection of Leishmania infantum infection in 43 dogs and five foxes from Alto-Douro and Arrábida, two known endemic areas in Portugal.

Development and Validation of a Viability RT‐qPCR Assay for Detecting Infectious Spring Viraemia of Carp Virus (SVCV)

Journal of Fish Diseases, Volume 49, Issue 8, August 2026.
ABSTRACT Spring viremia of carp virus (SVCV) is a contagious pathogen associated with significant mortality and economic losses in freshwater aquaculture. Although reverse transcription quantitative PCR (RT‐qPCR) enables rapid detection, it does not distinguish between infectious and non‐infectious viral particles, which may lead to overestimation of ...

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,

Correlative Imaging Captures a Fusion Mechanism as the Origin of Single Crystals with Multidomain Appearance

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
Nonclassical crystal growth via particle attachment and fusion yields metal–organic framework crystals with multidomain morphologies while retaining single crystallinity. Amorphous particles attach at crystal edges, crystallize, and align with the lattice, driving anisotropic growth, curved surfaces, and cavities.

Synthesis, Characterization, and Optical Properties of Undoped and Te‐Doped W(SxSe(1−x))2 and Core‐Shell WS2@W(SxSe(1−x))2 Nanotubes

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
W(SxSe1−x)2, Te:WSSe, and WS2@WSSe nanotubes were synthesized through controlled precursor composition. The W(SxSe1−x)2 and Te:WSSe nanotubes exhibit small‐diameter (<30 nm), high‐yield, and well‐defined excitonic transitions. Composition tuning via S/Se ratios increases interlayer spacing with higher Se content. The incorporation of Te remains limited
