Disseminated protothecosis diagnosed by evaluation of CSF in a dog     

Lane LV  Meinkoth JH  Brunker J  Smith SK  Snider TA  Thomas J  Bradway D  Love BC 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》2012,41(1):147-152

A 5-year-old female spayed Shetland Sheepdog Mix dog was evaluated for a history of recent seizure activity, progressive hind limb ataxia, polyuria, and polydipsia and no history of gastrointestinal signs. Physical examination findings included conscious proprioceptive deficits, ataxia, and anterior uveitis along with a hypermature cataract in the right eye. Results of a CBC, serum biochemical profile, urinalysis, and computed tomography scan of the brain were unremarkable. Cerebrospinal fluid (CSF) analysis revealed marked eosinophilic pleocytosis and rare organisms consistent with Prototheca spp within neutrophils and macrophages. On postmortem histologic examination, mononuclear inflammation and numerous intralesional algal organisms, similar to those seen on the cytologic preparation of CSF, were found in the brain, eyes, kidneys, and heart. Abnormalities were not detected on gross and histologic examination of the gastrointestinal tract. Cultures of CSF and subdural/olfactory bulb, but not intestinal tract, yielded growth of Prototheca spp, and PCR analysis and DNA sequencing confirmed the organism as Prototheca zopfii genotype 2. We have reported a rare case of disseminated protothecosis that was diagnosed by evaluation of CSF in a dog presented with neurologic signs and no overt enteric disease. Protothecosis should be considered as a rare cause of seizures, even in the absence of obvious enteric signs, and should be included in the differential diagnosis of eosinophilic pleocytosis.  相似文献   

Feline pituitary-dependent hyperadrenocorticism and insulin resistance due to a plurihormonal adenoma     

Cross E  Moreland R  Wallack S 《Topics in companion animal medicine》2012,27(1):8-20

A 12-year-old female spayed domestic short-haired cat presented for lethargy, poor hair coat, alopecia, difficulty walking, and mild polyuria/polydipsia. The cat's skin tore easily in the neck area during routine restraint for blood draw. Physical examination, blood analysis, and ultrasound imaging were all consistent with pituitary-dependent hyperadrenocorticism (PDH) with secondary insulin-resistant diabetes mellitus, which was nonketotic. Insulin therapy, fluids, and diet change were initiated for the diabetes mellitus and the owner reported improvement in clinical signs although the blood glucose measurements remained elevated. Surgical repair of the torn skin was successful. Although a guarded prognosis was given to the owner because of an advanced stage of hyperadrenocorticism, and the limited treatment options currently available for feline PDH, trilostane was agreed on as an initial therapeutic option. The day trilostane was to be initiated, the cat presented with dyspnea and the owner chose to euthanize. Because of the rarity of hyperadrenocorticism disease in the cat, permission was obtained by the owner for a necropsy to confirm suspected PDH as the underlying cause for insulin resistance and skin fragility syndrome.  相似文献   

Behavioral flexibility in Wasmannia auropunctata (Hymenoptera: Formicidae)     

Yarira Ortiz-Alvarado  Rafael Fernndez-Casas  Carlos A Ortiz-Alvarado  Emily Diaz-Iglesias  Bert Rivera-Marchand 《Journal of insect science (Online)》2021,21(4)

Worker division of labor is a defining trait in social insects. Many species are characterized by having behavioral flexibility where workers perform non-typical tasks for their age depending on the colony’s needs. Worker division of labor and behavioral flexibility were examined in the little fire ant Wasmannia auropunctata (Roger, 1863), for which age-related division of labor has been found. Young workers perform nursing duties which include tending of brood and queens, and colony defense, while older workers forage. When nurses were experimentally removed from the colony, foragers were observed carrying out nursing and colony defense duties, yet when foragers were removed nurses did not forage precociously. We also administered juvenile hormone analog, methoprene, to workers. When methoprene was applied, foragers increased their nursing and defense activities while nurses became mainly idle. The behavioral flexibility of foragers of the little fire ant may be evidence of an expansion of worker’s repertoires as they age; older workers can perform tasks they have already done in their life while young individuals are not capable of performing tasks ahead of time. This may be an important adaptation associated with the success of this ant as an invasive species.  相似文献   

Effect of Restricted Pasture Access on Pasture Dry Matter Intake Rate,Dietary Energy Intake,and Fecal pH in Horses     

Emily C. GlunkShannon E. Pratt-Phillips  PhD  Paul D. Siciliano 《Journal of Equine Veterinary Science》2013

Eight mature horses were used in a 4 × 4 Latin square design to determine the effect of restricted pasture access on dry matter intake rate (DMIR), energy intake, and fecal pH. Horses were randomly assigned to one of four groups (HGRPs), each containing two horses. HGRPs were randomly assigned to one of four treatments consisting of 3, 6, 9, or 24 hours of pasture access, for a period of 7 days. Treatments were switched every 7 days. The 3- and 6-hour groups were fed free choice mature grass hay while not grazing. Daily pasture dry matter intake (DMI) for each HGRP was estimated by calculating the difference between initial herbage mass of the grazing cell before grazing and residual herbage mass after 7 days of grazing. Total dry matter intake was the sum of pasture and hay DMI for the 3- and 6-hour treatments. Fecal pH was measured on day 7 of each period. Response variables were analyzed using analysis of variance for Latin square design. Restricting pasture access decreased mean pasture DMI (P = .02), pasture dietary energy (DE) (P = .02), and fecal pH (P < .001), but increased DMIR (P = .02). Mean total dry matter intake was not different (P = .16) among treatments. In conclusion, restricting pasture access accelerates pasture DMIR and decreases fecal pH, and although restricting pasture access decreases DE intake from pasture, it did not result in a decrease in total DE intake for horses having ad libitum access to hay.  相似文献

Sensory properties and aromatic composition of baked snacks containing brewer's spent grain     

Anastasia Ktenioudaki  Emily Crofton  Amalia G.M. Scannell  John A. Hannon  Kieran N. Kilcawley  Eimear Gallagher 《Journal of Cereal Science》2013

The incorporation of brewer's spent grain (BSG) into baked snacks (crispy-slices) was investigated in terms of nutritional, sensory and aromatic properties. Wheat flour was replaced with BSG at the levels of 10, 15 and 25%. Snacks containing 10% BSG exhibited high Crispiness index (Ci), low Crispiness work (Wc) and a high number of peaks during texture analysis, indicating that the crispiness of the samples was not negatively affected. However higher levels of BSG affected the texture and the crumb structure of snacks and the results were significantly different to the 100% wheat control. Addition of BSG altered the odour profile of the snacks as shown by the volatile profiles, however sensory results indicated that BSG-containing snacks at a level of 10% were highly acceptable and highlighted the possibility of using BSG as a baking ingredient in the formulation of enhanced fibre baked snacks.  相似文献   

Domoic Acid Improves the Competitive Ability of Pseudo-nitzschia delicatissima against the Diatom Skeletonema marinoi     

Emily K. Prince  Friederike Irmer  Georg Pohnert 《Marine drugs》2013,11(7):2398-2412

Because domoic acid, a neurotoxic secondary metabolite produced by marine diatoms in the genus Pseudo-nitzschia, is hypothesized to be part of a high affinity iron uptake system, we investigated whether domoic acid could improve the competitive ability of Pseudo-nitzschia delicatissima, and whether the availability of iron changed the outcome of competition experiments. We found that domoic acid had a slight negative effect on growth of the diatom Skeletonema marinoi when it was grown in monocultures. However, when S. marinoi was cultured with P. delicatissima the presence of domoic acid resulted in a reduction of S. marinoi cells by up to 38% and an increase in P. delicatissima cell numbers by up to 17% under iron replete conditions. Similar effects were not observed in low iron treatments. Domoic acid was not taken up by P. delicatissima cells. Overall, our results indicate that domoic acid can improve the competitive ability of Pseudo-nitzschia spp. and that iron is likely to be involved. This study provides an unusual example of indirect inhibition of competitor growth mediated by a secondary metabolite.  相似文献
