Replication kinetics, pathogenicity and virus-induced cellular responses of cattle-origin influenza A(H5N1) isolates from Texas, United States.

The host range of HPAIV H5N1 was recently expanded to include ruminants, particularly dairy cattle in the United States (US). Shortly after, human H5N1 infection was reported in a dairy worker in Texas following exposure to infected cattle. Herein, we rescued the cattle-origin influenza A/bovine/Texas/24-029328-02/2024(H5N1, rHPbTX) and A/Texas/37/2024(H5N1, rHPhTX) viruses, identified in dairy cattle and human, respectively, and their low pathogenic forms, rLPbTX and rLPhTX, with monobasic HA cleavage sites.

Lingual neoplasia in nonhuman primates: Description of five cases and a literature review.

Background: Documentation of lingual tumors is scarce in nonhuman primates.

Methods: Through a multi-institutional retrospective study we compile cases of primary and metastatic neoplasia in non-human primates.

Results: We describe five cases of lingual neoplasia.

Perosomus elumbis in a stillborn rhesus macaque (Macaca mulatta): A case report.

Perosomus Elumbis (PE) is a rare congenital disorder characterized by absence of caudal spine (lumbar, sacral, and coccygeal vertebrae). Here, we present the first reported case of PE in a rhesus macaque (Macaca mulatta) and relate our findings to those described in other species.

Salivary gland neoplasms in non-human primates: A case series and brief literature review.

Background: Salivary gland neoplasms are rare in non-human primates.

Methods: Thirty-five years of pathology records were reviewed at the Southwest (SNPRC) and Yerkes (YNPRC) National Primate Research Centers. An in-depth literature search for salivary gland neoplasms in non-human primates was performed.

Cytomegaloviral hypophysitis in a simian immunodeficiency virus-infected rhesus macaque (Macacca mulatta).

Rhesus macaques experimentally infected with Simian Immunodeficiency Virus (SIV) experience immunosuppression and often opportunistic infection. Among the most common opportunistic infections are rhesus cytomegalovirus (RhCMV), a ubiquitous betaherpesvirus that undergoes continuous low-level replication in immunocompetent monkeys. Upon SIV-mediated immunodeficiency, RhCMV reactivates and results in lesions in numerous organ systems including the nervous and reproductive systems.

Congenital anomalies in the baboon (Papio spp.).

Background: A comprehensive survey of the prevalence of congenital anomalies in baboons has not been previously reported. We report the congenital anomalies observed over a 26-year period in a large captive baboon colony.

Methods: A computer search was performed for all baboon congenital anomalies identified at necropsy and recorded on necropsy submissions.
