Concurrent gastro-oesophageal intussusception,trichobezoar and hiatal hernia in a cat

CASE HISTORY: An adult male Birman cat was evaluated for recurrent, intermittent vomiting or regurgitation, occasionally associated with abdominal discomfort.

CLINICAL FINDINGS AND DIAGNOSIS: Radiographs, including an oesophogram, indicated an oesophageal obstruction. Prior to treatment, the cat's condition deteriorated and it was euthanised at the owner's request. Post-mortem examination revealed a gastro-oesophageal intussusception, a trichobezoar impacted into the intussusceptum, and a dilated oesophageal hiatus consistent with a chronic hiatal hernia.

CLINICAL RELEVANCE: Gastro-oesophageal intussusception is a rare condition in cats. Its aetiology in relation to a pre-existing hiatal hernia and a trichobezoar is discussed.     

Mid‐gestation pregnancy is not disrupted by a 5‐day gastrointestinal mucosal cytoprotectant oral regimen of misoprostol

Reasons for performing study: To investigate effects of a 5‐day oral misoprostol regimen recommended for use in horses as a gastrointestinal mucosal cytoprotectant during colic on mid‐gestation pregnancies. Objectives: To monitor cervical tone, ultrasonographic characteristics of the uterus, cervix and conceptus, as well as serum progesterone and oestrone sulphate concentrations, and observations of general health, behaviour and comfort of mid‐gestation mares given a 5‐day course of misoprostol or control treatment. Methods: Eleven light horse and pony mares with known breeding dates were administered 5 µg/kg bwt misoprostol orally, twice daily for 5 days. General health and pregnancy status were monitored daily during treatment via general physical examination, as well as palpation and ultrasonography per rectum of the uterus, cervix and conceptus. Jugular serum was obtained during and for 5 days following treatment for assay of progesterone and oestrone sulphate concentrations. Additionally, daily 12 h video samples of the mares were obtained to evaluate behaviour and comfort. Results: All findings, including cervical tone, ultrasonographic characteristics of the uterus, cervix and conceptus, as well as progesterone and oestrone sulphate concentrations, and observations of general health, behaviour and comfort, were similar during misoprostol and control treatment. Conclusions: Treatment of pregnant mares with a gastrointestinal mucosal cytoprotectant regimen of oral misoprostol for 5 days did not disrupt pregnancy, nor adversely affect the general health and comfort of these mares. Additional investigation of treatment at earlier and later stages of gestation, for longer‐term treatment, as well as evaluating neonates for developmental disturbances, would add further information on safety of misoprostol during gestation. Potential relevance: These results provide some assurance of safety of a 5‐day gastrointestinal mucosal cytopretectant regimen of oral misprostol in mid‐gestation pregnant mares.     

Cross-sectional survey of pet ownership,veterinary service utilisation,and pet-related expenditures in New Zealand

ABSTRACT

Aims: To describe the demographics of and predictors for pet ownership, reasons for visiting a veterinarian, and pet-related expenditure in pet owners in New Zealand.

Methods: A cross-sectional online survey was conducted from 18–22 June 2015 using a permission-based panel of New Zealand residents aged ≥18 years. Questions included demographics of respondents, number of pets and reasons for owning or not owning pets, number of visits and reasons for visiting a veterinarian, and pet-related expenditure.

Results: Of the 1,572 respondents who completed the survey, 1,013 (64.4%) owned ≥1 pet. Of these, 443 owned dogs, 696 cats, 32 horses, 103 birds, 55 rabbits, and 159 owned fish. Companionship was the most common reason for getting dogs, cats, and birds; horses were mostly owned as a hobby, rabbits to provide fun for children, and fish as a source of relaxation. The majority of dog, cat, and rabbit owners considered their pets to be family members; horse owners almost equally considered their horses a hobby or a family member. The odds of pet ownership increased for respondents from a rural region, having a higher household income, having children and being female. Overall, 711/1,013 (70.2%) pet-owning respondents had taken ≥1 animal to the veterinarian in the previous year, with the most common reasons being for vaccination or annual check-ups or health issues. Respondents who considered their pets trusted companions, had a higher income, and owned dogs or cats compared with other species, were most likely to have taken their pet to a veterinarian. The greatest pet-related expenditure for all species was food. The median yearly veterinary expenditure was $200–499 by dog owners, $100–199 by cat owners, and <$100 by horse, bird, rabbit, and fish owners. The best source of information for pet-related issues was considered to be veterinarians by 724/1,001 (72.3%) owners, and the internet by 509/1,001 (50.8%) owners.

Conclusions: Among survey respondents, pet ownership was common and pets filled a variety of roles in the household. Pet owners reported spending considerable amounts of money on their pets each year, but some of them may be underutilising veterinary services despite veterinarians being considered as valuable sources of information about pet-related issues.     

Nitrogen fertilisation of weeping love grass (eragrostis curvula) at Dohne

Three field trials on the nitrogen fertilisation of the Ermelo cultivar of Eragrostis curvula conducted over seven years were collated and reviewed. Dry matter yields in tons obtained from these trials, excluding first year results, were used to derive the regression equation y = 3.9 x — 0.4 x² + 1.3 for the yield response to increments of 100 lb of nitrogen per morgen per annum. This response was nearly linear up to 300 lb of nitrogen, and more than 400 lb of nitrogen was required for maximum dry matter production. The crude protein content of the herbage increased progressively with increasing rates of nitrogen. The recovery of fertiliser nitrogen varied from 51 to 70 per cent ; the latter being achieved by (he application of 300 lb of nitrogen. Ammonium sulphate produced considerably higher dry matter yields than urea or limestone ammonium nitrate when applied in a single dressing in the spring. When the nitrogen was applied in three dressings the yields from urea and LAN were increased and no longer significantly different from those due to ammonium sulphate.

Exploiting Knowledge of Pathogen Effectors to Enhance Late Blight Resistance in Potato

Late blight disease of potato, caused by Phytophthora infestans, is the most serious disease of this crop on a global scale and is thus a threat to food security. Use of resistant potato cultivars to prevent late blight does not have a very successful history, as P. infestans genotypes have overcome the deployed resistances. Thus, there is a need to identify more durable resistances, or identify and develop novel forms of resistance that exploit vulnerabilities in the biology of P. infestans. Application of molecular biology tools in P. infestans research has recently culminated in the identification of several avirulence effectors matching specific resistances in potato, the sequencing of the P. infestans genome and identification of hundreds of candidate translocated pathogen ‘RXLR’ effector proteins that may promote disease progression. Strategies for prioritising these effectors for further research are revealing those that are highly expressed during infection, difficult for the pathogen to alter rapidly, essential for P. infestans pathogenesis and recognized by resistant accessions of Solanum spp. These effector characteristics are being used to identify and characterise resistances from Solanum germplasm that may prove more durable. In addition to RXLR effectors, P. infestans also produces a broad spectrum of additional secreted proteins. These are exposed to plant cells and may potentially act to trigger resistance, either as broad spectrum pathogen-associated molecular patterns or as specific effectors of resistance. Alternatively, conserved secreted proteins may be attractive targets for novel agrichemical development. We have silenced a diverse selection of these candidate secreted proteins in P. infestans and demonstrated their effects on late blight disease development. Results from these studies are aiding a deeper understanding of P. infestans disease development and identifying potential pathogen weaknesses for exploitation in future control measures.
