Abstract
Hepatic and pulmonary lesions are common in cetaceans, despite their poorly understood viral etiology. Herpesviruses (HV), adenoviruses (AdV) and hepatitis E virus (HEV) are emerging agents in cetaceans, associated with liver and/or pulmonary damage in mammals. We isolated and molecularly tested DNA for HV and AdV (n = 218 individuals; 187 liver and 108 lung samples) and RNA for HEV (n = 147 animals; 147 liver samples) from six cetacean families. All animals stranded or were bycaught in Brazil between 2001 and 2021. Positive-animals were analyzed by histopathology. Statistical analyses assessed if the prevalence of viral infection could be associated with the variables: species, family, habitat, region, sex, and age group. All samples were negative for AdV and HEV. Overall, 8.7% (19/218) of the cetaceans were HV-positive (4.8% [9/187] liver and 11.1% [12/108] lung), without HV-associated lesions. HV-prevalence was statistically significant higher in Pontoporiidae (19.2%, 10/52) when compared to Delphinidae (4.1%, 5/121), and in southeastern (17.1%, 13/76)-the most industrialized Brazilian region-when compared to the northeastern region (2.4%, 3/126). This study broadens the herpesvirus host range in cetaceans, including its description in pygmy sperm whales (Kogia breviceps) and humpback whales (Megaptera novaeangliae). Further studies must elucidate herpesvirus drivers in cetaceans.

Abstract
The aim of this study was to determine the presence of virulence genes and antibiotic resistance profiles in 164 Escherichia coli strains isolated from birds (feral pigeons, hybrid ducks, house sparrows and spotless starlings) inhabiting urban and rural environments. A total of eight atypical enteropathogenic E. coli strains were identified: one in a house sparrow, four in feral pigeons and three in spotless starlings. Antibiotic resistance was present in 32.9% (54) of E. coli strains. The dominant type of resistance was to tetracycline (21.3%), ampicillin (19.5%) and sulfamethoxazole (18.9%). Five isolates had class 1 integrons containing gene cassettes encoding for dihydrofolate reductase A (dfrA) and aminoglycoside adenyltransferase A (aadA), one in a feral pigeon and four in spotless starlings. To our knowledge, the present study constitutes the first detection of virulence genes from E. coli in spotless starlings and house sparrows, and is also the first identification worldwide of integrons containing antibiotic resistance gene cassettes in E. coli strains from spotless starlings and pigeons.

Abstract
Immunopathological damage in schistosomiasis consist of egg granuloma formation, which is a hypersensitivity reaction mediated by antigen-specific CD4+ T helper (Th) lymphocytes. Th cells are dependent on accessory cell-bound co-stimulatory signals for activation. The B7 molecules provide critical costimulation, as in their absence T cells are rendered unresponsive. We investigated the kinetics of B7-2 molecule expression in schistosomal egg granulomas by immunocytochemical analysis in situ. We also monitored major histocompatibility complex (MHC) class II, intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1) expression, as well as the presence of macrophages, T cells, and B cells. B7-2 expression was elevated in cells of the large granulomas of the acute (6-1/2 week) infection, and sharply declined thereafter. MHC class II expression was similarly elevated in the acute granulomas, but in contrast to B7-2, remained relatively constant throughout 12 1/2 weeks of infection. Moreover, ICAM-1 and VCAM-1 were expressed in acute and chronic granulomas. However, whereas ICAM-1 was constitutively expressed in normal liver, VCAM-1 was dramatically induced in the livers upon onset of disease. The findings suggest that the acute granulomas are rich in accessory cells with overall phenotypic configurations that support Th-cell activation, although at subsequent times, granulomas contain increasing numbers of B7-poor accessory cells capable of inducing Th-cell unresponsiveness. Thus, cellular interactions in early granulomas may be able to amplify egg-induced immunopathology, whereas interactions taking place in succeeding granulomas appear to precipitate its down-regulation.
