Carbon dioxide (CO2) laser keratectomy was compared to lamellar keratectomy (LK) and penetrating keratoplasty (PK) as a potential treatment option for equine corneal stromal abscessation. The medical records of 35 client owned horses undergoing surgical management of stromal abscessation were reviewed. Among those 17 underwent LK, 3 PK and 15 CO2 laser keratectomy. Healing of the stromal abscess was achieved in all treated eyes. Those horses undergoing CO2 laser keratectomy demonstrated few complications, and the time to healing and cosmetic outcome was comparable to those horses undergoing LK and PK. 相似文献

采用梅花鹿源坏死梭杆菌HNFnf分离株以不同浓度菌量于家兔耳缘静脉注射,尝试建立家兔感染坏死梭杆菌肝脓肿模型。通过观察家兔临床症状、剖检病变和病理组织学观察,建立了坏死梭杆菌分离株家兔感染模型。攻毒家兔7 d内全部死亡,死亡前家兔表现为采食减少、喜卧、后肢无力、消瘦等。尸体进行病理剖检可见明显病理变化,肺脏表面大量出血,且伴有结节样病变;肝脏质地较软,出现均匀的灰黄脓肿;脾脏严重肿大,呈暗紫色;肾脏多处出血斑;严重的肠道胀气,膀胱积尿。病理组织学观察可见肾脏近曲小管与远曲小管之间有少量的粉红色纤维素渗出;肝脏中形成明显的染色深蓝的脓肿结构,其周围有大量细胞核深染的炎性细胞浸润,肝脏肝小叶固有结构消失,肝细胞脂肪变性;肺泡和支气管内有大量红染的纤维素渗出。采取耳缘静脉攻毒方式,该细菌对家兔的最低致死量为1.2×1014 CFU。 相似文献

为了解引起山羊皮下脓肿的主要病原,本研究从四川乐至县、金堂县和蓬溪县3个山羊养殖场无菌采集患皮下脓肿病羊脓液样本19份,通过细菌分离培养、生化试验及特异性PCR方法对其病原进行检测和鉴定,并通过药敏试验测定分离病原的药物敏感性。结果显示,PCR扩增法共检测出病原菌19株,其中伪结核棒状杆菌、金黄色葡萄球菌及化脓隐秘杆菌分离率分别为57.9%(11/19)、26.3%(5/19)及15.8%(3/19);采用细菌分离培养法分离到3种形态不同的病原菌共计17株,其中革兰氏阳性短杆菌经鉴定为伪结核棒状杆菌,分离率57.9%(11/19),革兰氏阳性球菌经鉴定为金黄色葡萄球菌,分离率为21.1%(4/19),革兰氏阳性杆菌经鉴定为化脓隐秘杆菌,分离率为10.5%(2/19),PCR鉴定较细菌分离培养法灵敏度更高。3种病原菌对丁胺卡那、氟苯尼考等多种药物敏感。结果表明,伪结核棒状杆菌是引起该地区山羊皮下脓肿的主要病原,金黄色葡萄球菌和化脓隐秘杆菌同样可引起山羊皮下脓肿,特异性PCR方法较细菌分离培养更为高效、准确。本研究结果可为后续进一步分析其生物学特性,以及四川地区山羊皮下脓肿的综合性防制提供依据。 相似文献

Premortem magnetic resonance imaging (MRI) was performed in two cats with brain stem abscessation confirmed post mortem by histology and recovery of multiple bacterial species. The MRI features of the abscesses were distinctive and included a thick and marked enhancement of the abscess capsule and extension of the lesion from a tympanic bulla in one cat. A focal area of increased signal intensity was present on T2-weighted images. A circumscribed area of decreased signal intensity was surrounded by a ring of increased signal intensity on precontrast T1-weighted images. A center of decreased signal intensity with a thick, markedly enhanced abscess capsule was observed on post contrast T1-weighted images. These findings are compared to the current experimental and clinical literature of brain abscess. The underlying pathogenesis of MRI features is reviewed. 相似文献

A 2‐month‐old female goat was presented for depressed mental status and multifocal central neurologic signs 3 weeks after hot‐iron disbudding. Conventional magnetic resonance imaging (MRI) findings included a large intra axial mass in the left frontal lobe that was T2 hyperintense and T1 hypointense centrally with a contrast‐enhancing peripheral capsule and perilesional T2 hyperintensity. A restrictive pattern was present in diffusion‐weighted imaging. Magnetic resonance spectroscopy demonstrated an increased amount of succinate, acetate, amino acids, lipids; minimal amounts of lactate; and decreased amounts of N‐acetyl aspartate and choline. A cerebral abscess due to Trueperella pyogenes was confirmed from necropsy and tissue culture. 相似文献

Acquired oronasal fistula is a rare cause of chronic nasal disease in ferrets (Mustela putorius furo) and other species. An adult male ferret presented with an acute unilateral swelling on the head and a 1-year history of sneezing. Physical examination and diagnostic procedures revealed an oronasal fistula of dental origin with concurrent abscess formation. Treatment included drainage of the abscess, treatment of the infection, extraction of the teeth involved in the oronasal fistula, debriding of the fistula edges, and placement of a medicated gauze. To the authors’ knowledge, this is the first report of an acquired oronasal fistula in a domestic ferret. 相似文献

A 4-month-old Thoroughbred filly presented with pyrexia, inappetence and diarrhoea. Abdominal ultrasonography revealed a multilobulated abdominal mass that was determined to be associated with the caecum using computed tomography. Computed tomography also identified mesenteric lymphadenopathy and a pulmonary mass in the left caudal lung lobe. Percutaneous aspiration of the abdominal mass yielded pure growth of Rhodococcus equi. The filly responded in a positive fashion to the administration of clarithromycin, rifampin and gallium maltolate. Follow-up computed tomography revealed complete resolution of the abdominal mass and lymphadenopathy. Extrapulmonary disorders associated with R. equi should be considered even when thoracic ultrasonography reveals no evidence of pulmonary pathology. Although intra-abdominal abscesses have a grave prognosis, successful treatment is possible. Gallium maltolate can be safely administered to foals and may improve patient outcomes. 相似文献
