Bartonella henselae has been implicated as a causative agent of chronic uveitis in people and in some cats. The objective of this study was to determine whether Bartonella species seroprevalence or titer magnitude varies among cats with uveitis, cats without ocular diseases recorded and healthy cats, while controlling for age and risk of flea exposure based on state of residence. There was no difference in seroprevalence rates or titer magnitude between cats with uveitis and cats with non-ocular diseases. Healthy cats were more likely to be seropositive for Bartonella species than cats with uveitis. The median Bartonella species titer was 1:64 for all groups, although healthy cats were more likely to have higher titers than cats with uveitis and cats with non-ocular disease. The results suggest that serum antibody tests alone cannot be used to document clinical uveitis associated with Bartonella species infection. 相似文献

The objective of this study was to investigate the protein, amyloid A3 (AA3), in equine colostrum and early milk. We hypothesized that AA3 was consistently present in equine colostrum and early milk, that no correlation existed between serum and colostrum concentrations of this protein in individual mares at parturition and that colostrum/milk concentrations of this mammary protein may be affected by age, breed, length of gestation and/or induction of parturition. Thirty-eight peripartum mares and seven non-pregnant, non-lactating mares were included in the study. Mean serum concentrations of this protein in the pregnant and non-pregnant mares were consistent with previous reports. Amyloid A3 was found in all colostrum and early milk samples at consistently higher concentrations than in peripartum maternal serum. There was no correlation between serum AA and colostrum AA3 concentrations at parturition. Age and breed effects were not significant. Increased gestation length and induction of parturition were associated with decreased colostrum and milk AA3 concentrations. We conclude that AA3 is consistently present in equine colostrum and early milk. The production of this protein in the mammary gland is likely to be under different stimulus to the production of serum AA, and may have protective effects in the neonatal intestine. 相似文献

A 12-year-old, male Yorkshire terrier was presented for acute pulmonary oedema. Thoracic radiographs showed a linear metallic foreign body within the cardiac silhouette. Echocardiogram showed a hyperechoic line extending through the left ventricle, the mitral valve, leading into the left atrium. A 4 cm long Kirschner wire was surgically removed by left fourth thoracotomy. The dog died two days after surgery for acute pulmonary oedema. Necropsy showed thrombi on the mitral leaflets that impeded their movement. 相似文献

Because of recent interest in bacteriophage therapy in poultry, information regarding the interaction of bacteriophages and potential host bacteria in the environment should be collected. The present studies were initiated with a rather typical commercial broiler integrator within the south-central United States to examine environmental Salmonella levels in two broiler complexes, attempt to isolate Salmonella-lytic bacteriophages, and elucidate a possible reason for differing apparent Salmonella prevalence. Significantly (P < 0.05) less Salmonella was isolated from houses in complex 1 (15/44 [34%] Salmonella-positive drag swabs) as compared to houses in complex 2 (22/24 [92%]). A total of seven Salmonella-lytic bacteriophages were isolated from Salmonella-positive environments, and two bacteriophages were isolated from a single Salmonella-negative house. During the initial bacteriophage isolation, individual bacteriophages did not replicate in the Salmonella host isolated from the same environment, and lysis of additional Salmonella hosts relied on high numbers of bacteriophage to be present. This suggests that the presence of these bacteriophages in the environment of a commercial broiler house had little to no effect on the presence of Salmonella. This study highlights the need to find additional bacteriophage sources, more effective isolation methods, and more innovative approaches to using bacteriophages to treat enteric disease. 相似文献

BACKGROUND: Survivin, a member of the inhibitor of apoptosis protein family, has a dual role in tumor cell proliferative and antiapoptotic pathways. Survivin expression has been shown to be a negative prognostic factor in several cancers of humans, including B-cell non-Hodgkin's lymphoma. HYPOTHESES: High survivin expression will be a negative prognostic factor in dogs with lymphoma (LSA) treated with chemotherapy. In addition, survivin expression will be upregulated in relapsed canine LSA when compared with patient-matched, pretreatment biopsies. ANIMALS: Thirty-one client-owned dogs with stage IIIa or IVa LSA. METHODS: Retrospective evaluation of survivin immunoreactivity was performed on pretreatment lymph node biopsies and patient-matched samples obtained from dogs at relapse after being treated with an abbreviated CHOP-based protocol. RESULTS: In this population of dogs presenting with stage IIIa or IVa B-cell LSA, those dogs that had high survivin immunoreactivity scores had a significantly (P < .01, hazard ratio = 0.30) shorter median disease-free interval than did dogs with low survivin immunoreactivity scores (171 days versus 321 days, respectively). Survivin immunoreactivity was not significantly different in relapsed canine LSA when compared with patient-matched, pretreatment biopsies. CONCLUSIONS AND CLINICAL IMPORTANCE: Survivin expression is a negative prognostic factor that can predict early treatment failure of dogs that present with stage IIIa or IVa, B-cell LSA when treated with a CHOP-based protocol. 相似文献

Proliferative gill disease (PGD), caused by the myxozoan parasite Henneguya ictaluri, is the most prevalent parasitic infection affecting commercial channel catfish (Ictalurus punctatus) aquaculture. There are currently no effective chemotherapeutic or biological control measures for PGD, which often peaks during the spring and fall when water temperatures are between 16-25 degrees C. The current diagnostic techniques of gross examination of gill clip wet mounts and histopathology are subject to false-negatives during the early stages of infection, and the quantifiable nature of end-point polymerase chain reaction (PCR) is subjective. Consequently, a rapid and more sensitive quantitative real-time PCR assay was developed for the detection of H. ictaluri during the early stages of infection in channel catfish. A 23 base-pair TaqMan probe was designed based on previously published H. ictaluri PCR protocols. The sensitivity of the assay was the equivalent of a single H. ictaluri actinospore, and in a pond challenge study, quantitative real-time PCR proved to be more sensitive than gross examination, microscopic examination of gill clip wet mounts, and histopathologic examination of gill tissue sections. Future applications of this assay will focus on developing methodologies to be used in conjunction with current pond-monitoring protocols to evaluate potential treatments and better manage this significant seasonal disease. 相似文献

Objective: To determine the antinociceptive effects of epidural administration of morphine or buprenorphine in cats by use of a thermal threshold model. ANIMALS: 6 healthy adult cats. PROCEDURES: Baseline thermal threshold was determined in duplicate. Cats were anesthetized with isoflurane in oxygen. Morphine (100 microg/kg diluted with saline [0.9% NaCl] solution to a total volume of 0.3 mL/kg), buprenorphine (12.5 microg/kg diluted with saline solution to a total volume of 0.3 mL/kg), or saline solution (0.3 mL/kg) was administered into the epidural space according to a Latin square design. Thermal threshold was determined at various times up to 24 hours after epidural injection. RESULTS: Epidural administration of saline solution did not affect thermal threshold. Thermal threshold was significantly higher after epidural administration of morphine and buprenorphine, compared with the effect of saline solution, from 1 to 16 hours and 1 to 10 hours, respectively. Maximum (cutout) temperature was reached without the cat reacting in 0, 74, and 11 occasions in the saline solution, morphine, and buprenorphine groups, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: Epidural administration of morphine and buprenorphine induced thermal antinociception in cats. At the doses used in this study, the effect of morphine lasted longer and was more intense than that of buprenorphine. 相似文献

In 360 samples of colostrum and 36 samples of blood of warmblood mares, the concentration of immunoglobulin G (IgG) was evaluated in the post partal period with an ELISA and the results were compared to values obtained with 2 field methods--refractometry and colostrometry. A significant correlation (p < 0.0001) was determined between ELISA and colostrometry (r = +0.88) and between ELISA and refractometry (r = +0.93). So both field-methods seem suitable for evaluation of the colostral IgG-concentration in mares. Further the kinetic of the IgG concentration in colostrum, the volume of colostrum and the total amount of IgG was measured in the 12 hours post partum (p.p.) in each half udder of 36 mares of different parity. Immediately p.p. primiparous mares have a greater mean concentration of IgG (68 mg/ml) than multiparous mares (51 mg/ml). However, multiparous mares have a mean colostral volume of 1020 ml whereas, in primiparous mares, a mean volume of 527 ml was determined within the first three hours p.p. As a result of this the total amount of IgG was lower in primiparous (31.5 g) than in multiparous mares (48.5 g). A significant decrease of IgG concentration was measured in multiparous mares in the 1.5 hours following partum versus 3 hours in primiparous mares. The mean IgG concentration in the blood serum of the 36 mares immediately p.p. was 13.4 +/- 3.6 mg/ml. No significant correlation was observed between values of IgG concentration in the blood and in the colostrum of the mares. 相似文献
