Pathology of cryptosporidiosis in raccoons: case series and retrospective analysis, 1990-2019.

Cryptosporidiosis is an intestinal protozoal disease of public health importance caused by spp. Despite the high synanthropism of raccoons, studies describing the pathology of spp. infections in this species are lacking.

Immunohistochemical analysis of pigment cell tumors in two cyprinid species.

Pigment cell tumors, also known as chromatophoromas, are cutaneous spindle cell neoplasms originating from pigment cells (chromatophores) in the dermis of teleosts, amphibians, and reptiles. Chromatophoromas share similar histologic morphology to other spindle cell tumors and are not always pigmented. Therefore, immunohistochemical analysis may be useful in distinguishing these neoplasms from tumors of other cellular origin when poorly pigmented.

Diversity of Veronaea botryosa from different hosts and evaluation of laboratory challenge models for phaeohyphomycosis in Acipenser transmontanus.

Veronaea botryosa has been identified as a pathogen of cultured white sturgeon Acipenser transmontanus. In 2015, samples from 19 white sturgeon were received for diagnosis, of which 14 cultured positive for V. botryosa.

Stereological study of pyramidal neurons in the human superior temporal gyrus from childhood to adulthood.

The association cortex of the superior temporal gyrus (STG) is implicated in complex social and linguistic functions. Thus, reliable methods for quantifying cellular variation in this region could greatly benefit researchers interested in addressing the cellular correlates of typical and atypical function associated with these critical cognitive abilities. To facilitate this task, we first present a general set of cytoarchitectonic criteria targeted specifically toward stereological analyses of thick, Nissl-stained sections for the homotypical cortex of the STG, referred to here as BA22/TA.
