Oxidative stress in dogs with chronic inflammatory enteropathy treated with allogeneic mesenchymal stem cells
AbstractThe search for new biomarkers in patients with chronic inflammatory enteropathy (CIE) is ongoing in the human and veterinary medicine fields. Oxidative stress biomarkers (malondialdehyde [MDA], reduced glutathione [GSH], and albumin) have been studied in humans with chronic enteropathies, but among them, only albumin has been studied in dogs with CIE. Moreover, the effect of mesenchymal stem cell (MSCs) treatment with or without prednisone on these parameters has never been studied in dogs with CIE. These parameters were compared between healthy dogs (n  = 12) and dogs with CIE, and before and 1, 3, 6, and 12 ...

An outbreak of type C botulism in free-ranging Southern lapwing (Vanellus chilensis)
AbstractIn the fall of 2021, a significant mortality event in free-ranging Southern Lapwing (Vanellus chilensis) occurred on a soccer field in southern Brazil. Approximately 130 adult southern lapwings died after showing weakness and flaccid paralysis, characterized by the inability to move or fly and drooped wings. Due to the large number of animals affected, there was concern that they had been criminally poisoned. The affected birds were found to have ingested maggots in fresh poultry litter incorporated into the grass surface.Postmortem examinations of four southern lapwings revealed no significant gross and histologic...

Spent coffee grounds extract: antimicrobial activity against Paenibacillus larvae and its effect on the expression of antimicrobial peptides in Apis mellifera
AbstractIn recent years, natural alternatives have been sought for the control of beekeeping pathologies; in the case of American Foulbrood (AFB) disease, the use of synthetic antibiotics was prohibited due to honey contamination and the generation of resistant bacteria. The significant increase in population growth worldwide has led to great concern about the production of large amounts of waste, including those from agribusiness. Among the most important beverages consumed is coffee, generating thousands of tons of waste called spent coffee grounds (SCG). The SCG is a source of many bioactive compounds with known antimic...

Bovine neutrophils kill the sexually-transmitted parasite Tritrichomonas foetus using trogocytosis
AbstractThe protozoan parasiteTritrichomonas foetus (T. foetus) is the causative organism of bovine trichomonosis (also referred to as trichomoniasis), a sexually-transmitted infection that reduces fertility in cattle. Efforts to control trichomonosis on cattle farms are hindered by the discouragement of antibiotic use in agriculture, and the incomplete, short-lived protection conferred by the current vaccines. A more complete mechanistic understanding of what effective immunity toT. foetus entails could enable the development of more robust infection control strategies. While neutrophils, the primary responders to infecti...

Spillover of an endemic avian Influenza H6N2 chicken lineage to ostriches and reassortment with clade 2.3.4.4b H5N1 high pathogenicity viruses in chickens
AbstractPrior to 2017, chicken production in South Africa had only ever been affected by an endemic strain of H6N2 low pathogenic avian influenza (LPAI), but since 2017, an outbreak of Goose/Guangdong clade 2.3.4.4b H5N8 high pathogenicity avian influenza (HPAI) introduced by wild birds, followed by clade 2.3.4.4b H5N1 HPAI (2021-present), affected the country. In the present study, the viruses from seven cases of H6N2 LPAI from commercial poultry between October 2019 and August 2020 were genome-sequenced along with an H5N2 HPAI virus, and phylogenetic analysis was performed. The H5N2 HPAI virus caused localized outbreaks ...

Search for antibodies against Trichinella in two synanthropic Procyonidae species from southeast Mexico: white-nosed coatis (Nasua narica) and raccoons (Procyon lotor)
AbstractTrichinella is a nematode that are spread by the consumption of parasitized meat. Carnivora, a mammalian order, serve as key hosts for this parasite. However, evidence ofTrichinella in wildlife from the Neotropics is extremely scarce, with reports documenting its presence only for five carnivore species: two Felidae, one Otariidae and two Mustelidae. Other widely distributed species that are consumed as bushmeat, such as Procyonidae, have not been studied in this context. A long-term study was performed for antibodies againstTrichinella in coatis (Nasua narica) and common raccoons (Procyon lotor) in southeastern Me...
