Diversity of spp., spp. and spp. in vampire bats.

Although bats (Mammalia: Chiroptera) act as natural reservoirs for many zoonotic pathogens around the world, few studies have investigated the occurrence of agents in bats, especially vampire bats. The family (order Rickettsiales) encompasses obligate intracellular bacteria of the genera , , , , , and . The present study aimed to investigate, using molecular techniques, the presence of species of , , and in vampire bats sampled in northern Brazil.

Hereditary transthyretin amyloidosis: a myriad of factors that influence phenotypic variability.

Hereditary transthyretin-related amyloidosis (ATTRv amyloidosis) is a rare and progressively debilitating disease characterized by the deposition of transthyretin (TTR) amyloid fibrils in various organs and tissues, most commonly in the heart and peripheral nerves. This pathological deposition can lead to significant organ dysfunction and, ultimately, organ failure. ATTRv amyloidosis exhibits a broad range of clinical presentations, from purely neurological symptoms to purely cardiac manifestations, as well as mixed phenotypes which result from both neurological and cardiac implications.
