Objectives The aims of this study were to evaluate: owners’ perceptions and priorities on the treatment and monitoring of feline diabetes mellitus (DM); the perceived effectiveness of the communication between veterinarians and clients regarding disease management; and the impact DM has on the owners’ everyday lives and human–pet bonds. Methods An initial questionnaire, then an adapted second questionnaire, were available to owners of cats with DM on vetprofessionals.com . Results A total of 748 questionnaires were completed. At diagnosis, fewer than half of veterinarians discussed how to recognise unstable diabetes (46%) or home blood glucose monitoring (HBGM) (40%). Owners were disappointed that the importance of diet on diabetic remission/stabilisation and HBGM were not discussed. Only 49% of respondents were supervised by a veterinarian/veterinary nurse while first drawing up insulin and injecting their cat. Websites/online forums that owners found themselves were most useful when learning about their cat’s diabetes (76% agreed). Over a third of cats (39%) were not fed a ‘diabetic’ diet but, impressively, 71% of owners used HBGM. Initial concerns about costs, boarding, the effect on their daily life and potential negative impact on the human–pet bond reduced significantly after initiating treatment ( P <0.0001). Conclusions and relevance Caring for a diabetic cat requires significant owner commitment, plus support by the veterinary team for the owner and their cat. It is difficult to discuss all aspects of this complex disease with the owner in a single consultation; hence, it is important to involve the entire veterinary team in owner education and provide owners with informative material (eg, useful websites, printouts). Understanding owners’ priorities, fears, and which monitoring methods have helped others, is paramount to achieve owner compliance and satisfaction, and so improve the health and welfare of diabetic cats. This study provides useful information on the management of feline DM, which can be instrumental in educating future owners.
Background Campylobacter (C.) species are the most common bacterial cause of foodborne diarrhea in humans. Despite colonization, most animals do not show clinical signs, making recognition of affected flocks and disruption of the infection chain before slaughter challenging. Turkeys are often cocolonized with C. jejuni and C. coli. To understand the pathogen-host-interaction in the context of two different Campylobacter species, we compared the colonization patterns and quantities in mono- and co-colonized female commercial turkeys. In three repeated experiments we investigated the impact on gut morphology, functional integrity, and microbiota composition as parameters of gut health at seven, 14, and 28 days post-inoculation. Results Despite successful Campylobacter colonization, clinical signs or pathological lesions were not observed. C. coli persistently colonized the distal intestinal tract and at a higher load compared to C. jejuni. Both strains were isolated from livers and spleens, occurring more frequently in C. jejuni- and co-inoculated turkeys. Especially in C. jejuni-positive animals, translocation was accompanied by local heterophil infiltration, villus blunting, and shallower crypts. Increased permeability and lower electrogenic ion transport of the cecal mucosa were also observed. A lower relative abundance of Clostridia UCG-014, Lachnospiraceae, and Lactobacillaceae was noted in all inoculated groups compared to controls. Conclusions In sum, C. jejuni affects gut health and may interfere with productivity in turkeys. Despite a higher cecal load, the impact of C. coli on investigated parameters was less pronounced. Interestingly, gut morphology and functional integrity were also less affected in co-inoculated animals while the C. jejuni load decreased over time, suggesting C. coli may outcompete C. jejuni. Since a microbiota shift was observed in all inoculated groups, future Campylobacter intervention strategies may involve stabilization of the gut microbiota, making it more resilient to Campylobacter colonization in the first place.
Campylobacter (C.) is the most common food-borne zoonosis in humans, which mainly manifests with watery to bloody diarrhoea. While C. jejuni is responsible for most cases of infection, C. coli is less frequently encountered. The object of the study was to prove the clinical impact of mono- and co-colonisation of C. coli and C. jejuni on weaned piglets in an infection model and to investigate the impact on transepithelial transport processes in the jejunum and caecum. At an age of eight weeks, eight pigs were infected with C. coli (ST-5777), 10 pigs with C. jejuni (ST‑122), eight pigs with both strains, and 11 piglets served as control. During the four-week observation period, no clinical signs were observed. During dissection, both strains could be isolated from the jejunum and the caecum, but no alteration of the tissue could be determined histopathologically. Mono-infection with C. jejuni showed an impact on transepithelial ion transport processes of the caecum. An increase in the short circuit current (Isc) was observed in the Ussing chamber resulting from carbachol- and forskolin-mediated Cl− secretion. Therefore, we speculate that caecal colonisation of C. jejuni might affect the transport mechanisms of the intestinal mucosa without detectable inflammatory reaction.
