Special Issue Information

Dear Colleagues,

I am excited to invite you to contribute to this Special Issue on ‘Gastrointestinal Disease and Health in Pets’ that I have the honor of editing for Veterinary Sciences.

The intestinal tract serves as a vital organ for the digestion and absorption of nutrients, and it also functions as the body's largest immune organ. The health status of the gut is a key determinant of an animal's overall well-being. In the realm of pet animal welfare, gut health emerges as the foremost concern. This Special Issue is dedicated to highlighting original articles that delve into the intricacies of gut health and diseases in pets. This issue on ‘Gastrointestinal Disease and Health in Pets’ addresses the need to enhance the flow of information and communication between sciences by publishing selected research articles from leading laboratories in the field. It is hoped that this issue will further stimulate collaboration between scientists working on all aspects of pet gut health and disease.

Aggressive canine behavior poses a significant threat to public health. Understanding aggressive behavior is crucial for canine socialization and human–dog interactions. This study conducted an exploratory analysis of working dogs to investigate changes in gut microbiota and neurotransmitters associated with aggressive behavior. Notably, it represents the first research to systematically differentiate canine aggression into offensive and defensive subtypes for investigation. In this study, 56 working dogs from three regions of China, comprising different breeds (11 Spaniels, 13 German Shepherds, and 32 Belgian Malinois), aged 4.89 ± 1.54 years, and of both sexes (38 males and 18 females), were assessed and grouped for aggressive behavior using a C-BARQ-based questionnaire. Then, 16S rRNA sequencing and ELISA were employed to compare differences in gut microbiota and serotonin concentrations between aggressive (n = 35) and non-aggressive (n = 21) groups, as well as between offensive (n = 26) and defensive (n = 9) aggression subgroups. β-diversity analysis confirmed no significant correlation between aggressive behavior and gut microbiota composition (p > 0.05), suggesting a limited role of gut microbiota in modulating host behavior. Comparative analysis of gut microbiota composition revealed no significant differences in phylum-level abundance among different aggression types (p > 0.05). Notably, the non-aggressive group exhibited significantly higher relative abundances of Escherichia-Shigella, Erysipelotrichaceae_UCG-003, and Clostridium_sensu_stricto_1 compared to the aggressive group (p < 0.05). Random forest analysis identified Lactobacillus as a biomarker for canine aggressive behavior and Turicibacter as a discriminatory factor between offensive and defensive aggression. The results demonstrated a strong correlation between aggression and 5-HT neurotransmission. Serum serotonin levels were significantly lower in both the defensive (39.92 ± 2.58 ng/mL) and offensive (50.07 ± 3.90 ng/mL) aggression groups compared to the non-aggressive group (59.49 ± 2.76 ng/mL), with the lowest levels found in defensively aggressive dogs. The defensive group showed significantly lower serotonin levels than the offensive group (p < 0.001). The results demonstrate that different behavioral phenotypes in aggressive dogs lead to distinct gut microbiome compositions. This suggests that microbiome analysis may facilitate early diagnosis and preventive intervention before aggressive behavior manifests. As such, 5-HT shows potential as a monitoring tool for diagnosing canine aggression, with significant practical applications in canine behavior management. Full article

Feline panleukopenia (FPL), caused by the feline panleukopenia virus (FPLV), is a severe and highly contagious viral disease with high morbidity and mortality. Vaccination remains the gold standard for preventing and controlling this debilitating condition. The viral protein VP2 serves as the major immunogen of FPLV and represents the key target antigen in the development of a novel FPLV vaccine. Virus-like particle (VLP)-based vaccines have emerged as next-generation vaccine candidates due to their high immunogenicity and safe profile. In this study, a baculovirus expression vector system (BEVS) was employed to generate FPLV-VLPs through recombinant expression of the VP2 protein of a Chinese epidemic strain (Ala91Ser, Ile101Thr) of FPLV. The resulting FPLV-VLPs demonstrated markedly enhanced antigenicity and hemagglutination activity, achieving a hemagglutination titer of up to 1:216. Following vaccination, immunized cats developed high titers of anti-FPLV hemagglutination inhibition (HI) antibodies (1:216) and exhibited 100% protection against challenge with a virulent epidemic FPLV variant (Ala91Ser, Ile101Thr). These findings demonstrate that FPLV-VLPs hold strong potential as candidates for a novel subunit vaccine against FPLV infection. Full article
