Comparative glycomic analysis of hawk (), caiman () and sea turtle () tear films.

Glycans are recognized as biomarkers and therapeutic targets. However, these molecules remain a critical blind spot in understanding post-translational modifications, particularly in vertebrate species inhabiting diverse habitats. The glycans present in tears play a crucial role in eye protection and may be one of the key factors in adapting to direct environmental contact.

Immunization of mice and goats with Corynebacterium pseudotuberculosis-derived rPTS, rRBN and rCP40 recombinant proteins.

Antimicrobial photodynamic therapy stands out as a treatment characterized by a broad spectrum of antimicrobial action, being able to induce oxidative stress in pathogens, and porphyrins are photosensitizers with high selectivity to pathogens.

Hematological and clinical biochemistry profiles in Canindé goats infected by Corynebacterium pseudotuberculosis and bred in a tropical semi-arid region.

Caseous lymphadenitis (CLA), an infectious disease caused by Corynebacterium pseudotuberculosis in goats and sheep, is highly prevalent worldwide and is characterized by economic losses in small ruminant production. Currently available techniques for clinical and laboratory diagnosis of the disease lack market availability and/or sensitivity, and therefore, infected animals can remain in the herd, serving as a source of infection for other animals. The present study aimed to verify hematological and clinical biochemistry changes in goats naturally infected by C.

Immunoprophylactic properties of the Corynebacterium pseudotuberculosis-derived MBP:PLD:CP40 fusion protein.

Caseous lymphadenitis (CLA) is a disease that affects small ruminants, and the best way to prevent its spread on a herd is through immunoprophylaxis. Thus, we aimed to evaluate the MBP:PLD:CP40 fusion protein as a new CLA immunogen. The fusion protein was constructed by combining Corynebacterium pseudotuberculosis PLD and CP40 proteins with maltose-binding protein (MBP) as an intrinsic adjuvant.

Chemokine production induced by Corynebacterium pseudotuberculosis in a murine model.

Corynebacterium pseudotuberculosis is the etiological agent of caseous lymphadenitis. The main clinical sign of this disease is the development of granulomas, especially in small ruminants; however, the pathways that are involved in the formation and maintenance of these granulomas are unknown. Cytokines and chemokines are responsible for the migration of immune cells to specific sites and tissues; therefore, it is possible that chemokines participate in abscess formation.

The glycoproteomics of hawk and caiman tears.

Background: Glycoproteins are important tear components that participate in the stability of the ocular surface. However, the glycopeptides that are present in the tears of wild animals have not yet been described.
