Canine morbillivirus Canine distemper virus with concomitant Canine Adenovirus Canine parvovirus 2 and neospora caninum in puppies a retrospective immunohistochemical study
Scientific Reports, 2018Co-Authors: Selwyn Arlington Headley, Thalita Evani Silva De Oliveira, Alfredo Hajime Tanaka Pereira, Jessica Regina Moreira, Mariana De Mello Zanim Michelazzo, Barbara G Pires, V H B Marutani, Ana Aparecida Correa Xavier, Giovana Wingeter Di Santis, Joao Luis GarciaAbstract:A retrospective immunohistochemical study was designed to investigate the frequency of concomitant traditional infectious disease pathogens in puppies that died suddenly and review the aspects of associated pathogenesis. Fifteen puppies were evaluated; the pathology reports and histopathologic slides of these animals were reviewed to determine the pattern of histopathologic lesions. The intralesional identification of antigens of Canine (distemper) morbillivirus (CDV), Canine Adenovirus-1 and -2 (CAdV-1 and -2), Canine parvovirus-2 (CPV-2), Toxoplasma gondii, and Neospora caninum was evaluated by IHC within the histopathologic patterns observed. All puppies contained CDV nucleic acid by molecular testing. The most frequent histopathologic patterns were intestinal crypt necrosis (n = 8), white matter cerebellar demyelination (n = 7), necrohaemorrhagic hepatitis (n = 7), interstitial pneumonia (n = 7), and gallbladder oedema (n = 5). All puppies contained intralesional antigens of CDV in multiple tissues resulting in singular (n = 3), and concomitant dual (n = 3), triple (n = 5) and quadruple (n = 4) infections by CAdV-1, and -2, CPV-2, and N. caninum; T. gondii was not identified. Concomitant infections by CDV was observed with N. caninum (100%; 1/1), CPV-2 (100%; 8/8), CAdV-1 (100%; 8/8), and CAdV-2 (100%; 8/8). Intralesional antigens of CDV and not CAdV-1 were identified in cases of gallbladder oedema. The “blue eye” phenomenon was histologically characterized by corneal oedema and degenerative lesions to the corneal epithelium, without inflammatory reactions.

Disseminated melanized fungal infection due to Cladosporium halotolerans in a dog coinfected with Canine Adenovirus-1 and Canine parvovirus-2
Brazilian Journal of Microbiology, 2019Co-Authors: Selwyn Arlington Headley, Mariana De Mello Zanim Michelazzo, Bruno Elias, Nayara Emily Viana, Yuri Lima Pereira, Lucienne Garcia Pretto-giordano, Jhonata Fragoso Silva, Felipe Eduardo Scardovelli Silva, Laurival Antonio Vilas-boas, Karina Keller Marques Costa FlaibanAbstract:This report presents the pathologic findings associated with disseminated infection due to Cladosporium halotolerans in a dog that was simultaneously infected with Canine Adenovirus-1 (CAdV-1) and Canine parvovirus-2 (CPV-2). A 12-year-old, mixed breed dog, with a clinical history of neurological manifestations was submitted for routine autopsy due to poor prognosis. The principal pathologic findings were mycotic necrotizing nephritis, hepatitis, and splenitis with embolic dissemination to the brain resulting in mycotic necrotizing meningoencephalitis, ventriculitis, choroid plexitis, and obstructive hydrocephalus associated with intralesional and intravascular septate pigmented fungi. PCR and sequencing of the ITS region of fungi revealed that the intralesional fungal organisms had 82% nucleotide identity with members of the Cladosporium sphaerospermum complex of organisms. However, a PCR assay and sequencing of the beta tubulin gene confirmed that the organism identified in this dog had 100% nucleotide sequence identity with C. halotolerans . Using immunohistochemistry, intralesional antigens of CAdV-1 were identified within the epithelial cells of the liver and lungs; there was positive immunolabeling for CPV-2 antigens in degenerated cardiomyocytes. These findings confirmed the active participation of C. halotolerans in the development of disseminated cladosporiosis in this dog and represent a rare occurrence of concomitant infection with CAdV-1 and CPV-2.
