PARASITES OF NILE TILAPIA LARVAE OREOCHROMIS NILOTICUS (PISCES: CICHLIDAE) IN CONCRETE PONDS IN GUANACASTE, NORTHERN COSTA RICA

Parasites of Nile Tilapia larvae Oreochromis niloticus (Pisces: Cichlidae) in concrete ponds in Guanacaste, Northern Costa Rica

Tilapia is the second most important Biotin cultured species in the world fish culture but it can be affected by parasites.We conducted a cross-sectional parasitic study in tilapia larvae during sexual reversion for two seasons in Costa Rica.A total of 320 larvae from a concrete pond were necropsied and we found ten parasite species: Ichtyobodo sp.

Tangentially active polymers in cylindrical channels

We present an analytical and computational study characterizing Footwear the structural and dynamical properties of an active filament confined in cylindrical channels.We first outline the effects of the interplay between confinement and polar self-propulsion on the conformation of the chains.We observe that the scaling of the polymer size in the c

A bispecific antibody exhibits broad neutralization against SARS-CoV-2 Omicron variants XBB.1.16, BQ.1.1 and sarbecoviruses

Abstract The Omicron subvariants BQ.1.1, XBB.1.5, and XBB.1.16 of SARS-CoV-2 are known for their adeptness at evading immune responses.Here, we isolate a neutralizing antibody, 7F3, with the capacity to neutralize all tested SARS-CoV-2 variants, including BQ.1.1, XBB.1.5, and XBB.1.16.7F3 targets the receptor-binding motif (RBM) region and exhibits
