Three studies evaluating various aspects of the performance of pyriprole against the cat flea, Ctenocephalides felis, on dogs demonstrated that 12.5% pyriprole applied as a spot-on provides rapid, long-lasting efficacy against adult cat fleas, even under severe flea challenge. Speed of kill data indicate treatment with this product can interrupt an already established adult flea infestation, whereas monthly treatment can prevent reinfestation. Pyriprole disrupts the flea life cycle by killing adult fleas before they lay eggs for at least 30 days after treatment. The residual effect of pyriprole on debris from treated dogs (dander, hair, scales, and flea feces) resulted in a decreased ability of cat flea larvae to complete development to the adult stage for 2 weeks after application. Based on the results of these studies, 12.5% pyriprole represents a valuable new tool in the control of the cat flea, C. felis, on dogs. 相似文献

To describe the clinical features and treatment of a cat that was initially presented with fibrotic myopathy affecting the left tensor fascia lata. Approximately 5 months later, the cat was presented again with multiple idiopathic fibrotic myopathies, affecting the ipsilateral rectus femoris and the contralateral semitendinosus muscles. These were each separate lesions and occurred without known history of trauma. Surgical resection of the fibrotic portion of the affected muscles resulted in immediate, but not long-term, resolution of clinical signs. 相似文献

The attitudes and behaviours of cat owners in regard to treatment of cats may have a cumulative effect on the food availability, reproduction, density and welfare of the free-roaming cat population and thus also on the extent of cat overpopulation. Understanding this is thus a vital step in the a priori planning of cat management programs on any scale, as well as in developing public education programs on this issue. Although recent years have seen an accumulation of knowledge in regard to cat owners' attitudes and behaviours, the findings vary among countries and locations and in Israel this has never been investigated systematically. Using a questionnaire provided to cat owners in veterinary clinics, this study aimed at identifying those attitudes and behaviours that may be contributing to cat overpopulation in Tel Aviv, Israel, and at exploring the socio-economic factors that influence this problem. The findings show that the influential factors can be predicted from the cat owners' socio-economic status, mainly education and income, as well as gender and age. A consistency in those cat owner behaviours that contribute to cat overpopulation was also uncovered, revealing a sub-population of individuals who persist in the undesirable behaviours. Finally, a strong relationship between attitude and consequent behaviour was demonstrated, indicating the importance of education and targeted publicity as a means to influence attitudes and thereby change behaviours in this respect. We propose several measures by which to reduce the current extent of cat owners' contribution to the cat overpopulation: discouraging unwanted owner behaviours such as abandonment of their cats and allowing them to breed; promoting awareness of the neutering option among cat caretakers; and increasing pre-adoption neutering rates in shelters. Regional and national laws promoting responsible pet ownership need to be enacted. By improving the current level of knowledge and awareness among cat owners regarding cat overpopulation issues, and encouraging a more responsible attitude, cat owners' bond with their cats could be strengthened, as well as their bond with and contribution to their environment. 相似文献

A 10-year-old neutered male Persian cat and a 4-year-old spayed female domestic shorthair (DSH) cat were evaluated for acute-onset severe lateralising tetraparesis and hemiplegia, respectively. Both cats also had left-sided Horner's syndrome. Neurological examination of the cats localised the lesion to cranial to C5 in the Persian and the left cervical intumescence (C6-T2) in the DSH. Physical examinations were otherwise generally unremarkable. Routine laboratory tests and spinal radiography were normal for the Persian cat and were not performed for the DSH cat. A cerebrospinal fluid (CSF) tap was attempted for the Persian cat but aborted because of gross blood contamination, and was not performed for the DSH cat. Magnetic resonance imaging (MRI) of the Persian cat revealed a lesion within the spinal parenchyma at segments C1 to C3 (slightly more left-sided) which was iso- to hypointense on T1-weighted scans and hyperintense on T2-weighted scans, and which enhanced slightly with gadolinium. MRI of the DSH cat revealed a lesion within the spinal parenchyma at segment C7 (predominantly left-sided) which was hypointense on T1-weighted scans and hyperintense on T2-weighted gradient echo scans. Contrast was not administered. The MRI findings in both cases were highly suggestive of acute spinal cord infarction, based upon comparison to human cases. Both cats made full neurological recoveries with supportive treatment only. This paper describes two cases of suspected acute spinal cord infarction in the cat, demonstrates the potential diagnostic value of MRI, and discusses the clinical syndrome of this condition with a brief review of published cases. 相似文献

This case series reviews previous publications and reports four feline spinal epidural empyema cases that presented with non-ambulatory thoracolumbar myelopathy. Two cats underwent myelography and two MRI. Bacteria were obtained in three cases, in two from epidural abscesses and from a tail base wound in one; histopathological examination of epidural tissue showed pyogranulomatous changes in the remaining cat. Three cats were treated by surgical decompression plus antimicrobial therapy and one cat was treated medically. All cats showed satisfactory improvement following treatment over a follow-up period of 3 months. Spinal epidural empyema is a rare condition but all cats in this series had favourable outcomes. 相似文献

Objective: To report the clinical signs, imaging findings and surgical treatment of a meningoencephalocele in a cat. Study Design: Case report. Animal: Domestic shorthaired cat, 4 months old. Methods: A parietal meningoencephalocele was identified and characterized by magnetic resonance and computed tomography (CT) imaging. The abnormal tissue was excised and submitted for histopathology, and the meningeal and skull defects were reconstructed. Results: The cat made a full recovery and the episodes of aggression, restlessness and apparent discomfort that occurred before surgery ceased after surgical treatment. The cat was clinically normal 1 year postoperatively. Conclusion: Surgical management of meningoencephalocele in cats may be a viable treatment option. 相似文献

This study was examined whether the species of felid affects synchronization accuracy at the G0/G1 stage of the cell cycle and the occurrence of apoptosis by different protocols, such as serum starvation, confluent and roscovitine treatment. Skin fibroblast cells were obtained from the Asian golden cat, marbled cat, leopard and Siamese cat. The cells from each animal were treated with either serum starvation for 1–5 days, cell confluency‐contact inhibition for 5 days or roscovitine at various concentrations (7.5–30 μm ). Flow cytometric analysis revealed that serum starvation for 3 days provided the highest cell population arrested at the G0/G1 stage, irrespective of the felid species. In all species, 100% confluency gave a significantly higher percentage of cells arrested at the G0/G1 stage compared with the non‐treated control cells. The effects of roscovitine treatment and the appropriate concentration on the rates of G0/G1 cells differed among the felid species. Serum starvation for more than 4 days in the marbled cat and Siamese cat and roscovitine treatment with 30 μm in the Asian golden cat and leopard increased the rates of apoptosis. In conclusion, different felid species responded to different methods of cell cycle synchronization. Asian golden cat and Siamese cat fibroblast cells were successfully synchronized to G0/G1 stage using the serum starvation and roscovitine treatment, whereas only confluency‐contact inhibition treatment induced cell synchronization in the leopard. Moreover, these three methods did not successfully induce cell synchronization of the marbled cat. These findings may be valuable for preparing their donor cells for somatic cell nuclear transfer in the future. 相似文献

The aim of this study was to evaluate the effect of antioxidant catalase (CAT) and superoxide dismutase (SOD) in semen extender on motility, viability and acrosomal integrity of frozen-thawed cat spermatozoa. Semen was collected by using an artificial vagina from five domestic cats (two ejaculates/cat). Spermatozoa were diluted in egg yolk Ttris-fructose citrate solution (EYT-FC) without glycerol and cooled at 4°C for 1 h, then diluted further with EYT-FC with glycerol (7% final concentration) and 400 IU/ml of CAT (treatment 1) or SOD (treatment 2) or without antioxidants (control). Before freezing using a styrofoam box, diluted spermatozoa filled in 0.25-ml straws were equilibrated for 1 h at 4°C. After thawing, spermatozoa were assessed for motility, viability and acrosomal integrity. Cryopreservation significantly impaired sperm motility, viability and acrosomal integrity (p < 0.05). However, motility, viability and acrosomal integrity of frozen-thawed cat spermatozoa in the EYT-FC with CAT, SOD and without the antioxidants were not significantly different. The average percentages of spermatozoa motility after thawing compared between control, treatment 1 and treatment 2 group were 43.5 ± 3.2, 42 ± 4.1 and 38 ± 4.5; for viability: 44.8 ± 3.5, 50.6 ± 5.7 and 47.1 ± 4.1 and for acrosomal integrity: 45 ± 3.5, 44.9 ± 3.4 and 44.4 ± 3.3, respectively. In conclusion, adding CAT and SOD to EYT-FC did not improve motility, viability and acrosomal integrity in cryopreserved cat spermatozoa. 相似文献

Idiopathic feline lower urinary tract disease (FLUTD) is a common clinical entity where different treatments, for example glycosaminoglycans (GAGs) such as pentosan polysulphate (PPS), are advocated. However, few treatments have been investigated by well-controlled clinical trials. This paper compares the use of PPS in FLUTD compared to placebo. Of the 18 cats in the experiment, nine were treated with PPS and nine were treated with placebo with subcutaneous injections of 3mg/kg PPS or placebo day 1, 2, 5 and 10. The study was double-blind, randomised and placebo-controlled. Revaluation was performed after 5 and 10 days, 2 weeks, 2, 6 and 12 months. There were no statistically significant differences concerning clinical signs between groups during treatment or at re-evaluation, except for pretreatment stressful events where PPS-treated cats had experienced significantly more stressful events compared to cats treated with placebo before entering the study. Six cats (33%) showed recurrence of clinical signs during the entire study period, and only one of these cats had more than one recurrent episode. One cat (placebo) was euthanased 7 days after initial treatment because of recurrence of clinical signs. Another cat (placebo) was euthanased due to other reasons after 6 months. At 2 weeks two cats (placebo and PPS) showed clinical signs. At 2 months re-evaluation one cat showed mild clinical signs. At 6 and 12 months all remaining 16 cats were healthy. Idiopathic, non-obstructive FLUTD is a self-limiting disease with good short-term and excellent long-term prognosis without treatment. Whether or not PPS may be beneficial in a subpopulation of cats with continuous or frequently recurring clinical signs may be elucidated in forthcoming double-blind, randomised and placebo-controlled trials including only this subpopulation of cats. 相似文献

Paracetamol, a common human analgesic, is potentially fatal in the cat unless specific therapy is started early. A cat two and one half years old was referred for treatment 14 h after paracetamol had been administered (173 mg/kg). The cat was moribund and cyanotic and subsequently became anaemic and icteric. Treatment consisted of N-acetylcysteine, ascorbic acid and DL-methionine to decrease toxic effects of the paracetamol and intravenous fluids, blood transfusion and amoxycillin as supportive treatment. The cat recovered clinically during the following 12 days, but some laboratory abnormalities were still present 3 weeks later. 相似文献

A spot-on metaflumizone formulation was evaluated to determine its adulticidal efficacy, effect upon egg production, and ovicidal activity when applied to flea infested cats. Eight male and eight female adult domestic shorthair cats were randomly assigned to either serve as non-treated controls or were treated topically with a minimum of 40mg/kg metaflumizone in single spot-on Day 0. On Days -2, 7, 14, 21, 28, 35, 42, 49, and 56, each cat was infested with approximately 100 unfed cat fleas, Ctenocephalides felis felis. On Days 1, 2, and 3, and at 48 and 72h after each post-treatment reinfestation, flea eggs were collected and counted. At approximately 72h after treatment or infestation, each cat was combed to remove and count live fleas. Egg viability was determined by examining hatched eggs after 5 days and adult emergence was determined 28 days after egg collection. Metaflumizone provided >/=99.6% efficacy against adult fleas from Days 3 to 45 following a single application. Following treatment, egg production fell by 51.6% within 24h and 99.2% within 48h. Following subsequent weekly infestations egg production from treated cats was negligible out to Day 38, with >/=99.5% reduction relative to non-treated cats. Where there were eggs to evaluate, metaflumizone treatment did not have any apparent effect on the hatching of eggs or on the development and emergence of adult fleas from the eggs produced by fleas from treated animals. 相似文献

A spot-on metaflumizone formulation was evaluated in adult domestic short hair cats to determine its adultidical efficacy against a flea strain that has reduced susceptibility to a number of insecticides. Eight cats served as non-treated controls, eight cats were treated with a metaflumizone formulation at 0.2 ml/kg (40 mg metaflumizone/kg) and eight cats were treated with fipronil 10% w/v-(s)-methoprene 12%w/v at 0.075 ml/kg (7.5-7.7 mg fipronil/kg:9.0-9.2 mg (s)-methoprene/kg). On days -1, 7, 14, 21, 28, 35, and 42 each cat was infested with approximately 100 unfed KS1 cat fleas, Ctenocephalides felis. At approximately 48 h after treatment or infestation, each cat was combed to remove and count live fleas. Treatment with metaflumizone provided > or = 99.3% efficacy for 3 weeks post-treatment and then 97.4, 91.4 and 86.2% efficacy at 4, 5 and 6 weeks post-treatment, respectively. Fipronil-(s)-methoprene provided 99.6% efficacy at 1 week post-treatment and then 97.6, 96.4, 71.3, 22.0 and 13.1% efficacy at weeks 2, 3, 4, 5 and 6, respectively. The reductions in flea numbers were significantly greater for the metaflumizone treatment than for fipronil-(s)-methoprene from 3 to 6 weeks after treatment. 相似文献

Feline intestinal trichomoniasis caused by Tritrichomonas foetus is associated with large bowel diarrhea in cats from many parts of the world. It has long been recognized as an economically important sexually transmitted disease that causes early abortion in cattle. Isolates of T. foetus from cattle are infectious for the large intestine of cats and isolates of T. foetus from cats are infectious for the reproductive system of cattle. The parasite is maintained by fecal-oral transmission in cats. The present study was conducted to examine the survival of a feline isolate of T. foetus, AUTf-12, under various conditions that are relevant to fecal-oral transmission in cats. Trophozoites were grown in TYM medium and then exposed to water, cat urine, dry cat food, canned cat food, clumping cat litter, or filter paper for various lengths of time and then re-cultured in TYM medium. Trophozoites survived exposure to distilled or tap water for 30 but not 60 min, while they survived for at least 180 min in urine. Trophozoites survived for 30 min on dry cat food but survived for 120-180 min in canned cat food. No survival of trophozoites was observed on cat litter but trophozoites survived for 15 min when placed on filter paper. Our results indicate that T. foetus can survive and be potentially infectious in water, urine, dry cat food and canned cat food. 相似文献

A case of bilateral, upper urinary tract infection caused by haemolytic E coli in a female Birman cat is presented. Ultrasonographic examination of the kidneys documented changes in size, outline, echogenicity and architecture. Ultrasound guided fine needle aspiration of fluid from the renal pelvis was used to make the diagnosis. Fluid was submitted for culture and sensitivity and based on the results, antimicrobial therapy was initiated. The treatment was monitored over a 406-day follow-up period. Despite extensive treatment with specific antibiotics and supportive therapy, recurrence of urinary tract infection occurred. 相似文献

A 6-year-old domestic shorthair male castrated cat was evaluated for sudden onset of vomiting and anorexia. A diagnosis of hypereosinophilic syndrome (HES) was made, and the cat was treated with imatinib mesylate. The cat had an initial clinical improvement with the normalization of the peripheral eosinophil count. After approximately 8 weeks of treatment, lethargy and anorexia recurred despite the normal eosinophil count and a significant proteinuric nephropathy was identified. Treatment with imatinib was discontinued. Ultrasound guided renal biopsies exhibited histologic, ultrastructural, and immunostaining changes indicative of a minimal change glomerulopathy (MCG) which has not previously been reported in the literature in a cat. The proteinuria and HES initially improved while the cat was treated with more traditional medications; however, both the problems persisted for 30 months that the cat was followed subsequently. Previous studies demonstrating the safety and efficacy of imatinib in cats do not report any glomerular injury or significant adverse drug reactions, and the exact cause of this cat's proteinuric nephropathy is uncertain. Nonetheless, the possibility of an adverse drug reaction causing proteinuria should be considered when initiating treatment with imatinib in a cat. 相似文献

Eleven cats in which subtotal colectomy with end-to-end jejunocolostomy was performed for the treatment of chronic obstipation secondary to pelvic fracture malunion were followed for at least 18 months. Seven cats had no recurrence of clinical signs and no longterm complications. In two cats, constipation was less severe and occurred less frequently; however, medical treatment was still required. In one cat, watery diarrhea gradually changed to semiformed feces of normal consistency by month 6; the cat was clinically normal at month 18. One cat had recurrence of constipation and was euthanatized after 2 years of medical treatment. 相似文献

家蚕(Bombyxmori)是卵滞育性鳞翅目模式昆虫,其滞育性受亲代卵孵化期(催青期)温度、光节律等环境因子诱导。为了研究家蚕滞育与温度和光照节律的关系,本文调查了温度、光照节律对家蚕sod基因和cat基因表达的影响。催青期中除了孵化期,25℃持续光照下(25LL)卵的sodmRNA均保持在较高水平,另外,sod基因在20℃光照黑暗(20LD)12h交替环境下的表达量要高于15℃持续黑暗(15DD)条件,且孵化后期这种现象更加明显。cat基因在25LL、20LD和15DD环境之间的表达量无差异,但是孵化后期(积温2160-3600℃.h),cat基因表达水平显著上调,这与在此阶段的蚕卵胚胎对滞育诱导环境温度和光节律比较敏感的结论相一致。此外,本文还调查了子代卵中sod基因和cat基因的表达情况。sod基因在人工活化卵(DTE)中的表达水平显著高于非浸酸的滞育性卵(DDE);卵龄24-192h,25LL子代卵逐渐进入滞育,sod基因表达量下调。低温黑暗条件会上调家蚕子代卵sod基因的表达水平。在初期的盐酸活化卵(DTE)中,cat表达量低于滞育卵(DDE),而后逐渐上升,直至接近滞育卵表达量,这表明盐酸可能会抑制cat基因表达。在恒温条件下,黑暗条件会促进子代卵上调cat表达。在温度光照协同作用下,20LD子代卵中cat表达量低于25LL和15DD。 相似文献
