爱犬"安乐死"老汉泪潸然

相依为命17年,爱犬在“年老”之际患上绝症。西安市北郊一对老夫妻不忍眼看如同亲子一样的黄狗“赖皮”受病痛折磨,遂决定为爱犬实施“安乐死”。“赖皮”安静地死去,可老两口的思念却远没有停止。     

Nonsuppurative encephalitis in a dog

A 4-year-old male German Hunting Terrier presented with tremor, dyspnea, trismus, spasms of the musculature of the larynx and pharynx, and hypothermia and subsequently died despite intensive clinical care. Prior clinical signs included vomitus and diarrhea. Microscopic examination of the brain revealed a multifocal nonsuppurative brain stem encephalitis; a few intralesional neurons contained intranuclear inclusions. By immunohistochemistry, Aujeszky disease virus (Suid herpesvirus 1) antigen was detected in neurons in the brain and in ganglion cells of the trigeminal ganglia. Viral culture of brain tissue confirmed the presence of Aujeszky disease virus. Histopathologic findings in the brain with the identification of Aujeszky disease virus by immunohistochemistry and polymerase chain reaction are consistent with Aujeszky disease virus-induced encephalitis. Sequencing revealed a 100% homology of the isolated Aujeszky disease virus with Aujeszky disease virus isolates of wild boar from Eastern Germany.     

Sarcocystis neurona encephalitis in a dog

A 1.5-year-old male Feist dog was presented to a veterinarian for reluctance to stand on the hind legs. Treatment included dexamethasone and resulted in a favorable initial response, but posterior paresis returned and progressed to recumbency, hyperesthesia, and attempts to bite the owner. The dog was euthanized. The brain was negative for rabies by fluorescent antibody analysis. Multiple foci of encephalitis were found in the cerebrum and particularly in the cerebellum. Protozoa morphologically consistent with Sarcocystis sp. were identified at sites of intense inflammation and malacia. Additionally, multiple schizonts were identified in areas without inflammation. Immunohistochemistry using both polyclonal and monoclonal antibodies specific for Sarcocystis neurona was strongly positive. No reaction to polyclonal antisera for Toxoplasma gondii or Neospora caninum was found. Polymerase chain reaction confirmed that the protozoa were S. neurona. Additional aberrant hosts for S. neurona other than horses have been identified, but S. neurona encephalitis has not been documented previously in the dog.     

让人与犬和谐相处——观《焦点访谈》之"做文明的养犬人"有感

2006年10月16日晚,中央电视台新闻频道《焦点访谈》栏目播出了一期当下城市居民都非常关注的话题——“做文明的养犬人”。其实,这个话题目前已成为城市管理中的热点难点问题,也一直是老百姓争论不休的话题。     

Ocular biology and diseases of Old World chameleons.

For centuries, Old World chameleons (Chamaeleonidae family) have been collected and studied for their unusual biology and features, which are unique among lizards and other vertebrates. They have advanced mechanisms for capturing prey with their tongue, but have a primitive mechanism for hearing. Chameleons have the most studied ocular system because of their highly adapted yet primitive biology. This system has specific features that are susceptible to new diseases, which may require novel therapies.     

警犬『咬』出杀妻男子

2005年3月2日上午9时许，广西自治区柳州市公安局刑侦支队警犬大队接到支队李杨林副支队长的出警指令：立即出动警犬到柳南区柳太路和平砖厂参与侦破一起命案。接到指令后，警犬大队大队长廖文伟迅速组织人员携带警犬“马蜂”、“剑客”赶到现场。     

Experiences with the silicone T-tube in man and dog

Silicone T-tubes are particularly useful for long-term stenting of the laryngotracheal airway. Silicone is useful when non-autogenous non-reactive soft material is wanted for use in the human and animal body. Two case reports illustrate the use of the silicone T-tube.     

Occurrence of anaerobic bacteria in diseases of the dog and cat.

A survey for anaerobic bacteria was conducted in 314 clinical specimens from dogs and cats. A total of 187 anaerobic isolates in pure and mixed culture were isolated from 111 of the specimens that contained anaerobic bacteria. Common isolated included Actinomyces (9.1%), Clostridium perfringens (19.3%), other Clostridium spp (11.2%), Peptostreptococcus anaerobius (7.5%), Bacteroides melaninogenicus (13.4%), other Bacteroides spp (17.6%), and Fusobacterium necrophorum (5.3%). Anaerobic bacteria were involved in serious lesions that often were life threatening to the animals. Antibiotic susceptibility data indicated that the lincomycin family, the penicillin family, chloramphenicol, and cephaloridine are preferred drugs for treatment of anaerobic infections. Data from the survey were used in formulation of a table to aid practitioners in clinical diagnosis of disease caused by anaerobes. Clostridium perfringens was isolated in large numbers from five of six dogs with a clinical diagnosis of canine hemorrhagic gastroenteritis and from one cat with hemorrhagic diarrhea. Experimental infections were induced in rats, using caine feces as inoculum. Induced lesions contained aerobic and anaerobic bacteria similar to those bacteria isolated in the clinical survey, indicating that feces may serve as a major source of these bacteria in clinical infections of the dog.     

A review of immunologic diseases of the dog.

The following review is based on notes used in the teaching of clinical immunology to veterinary students. Immune diseases of the dog are placed into six different categories: (1) type I or allergic conditions; (2) type II or auto- and allo-antibody diseases; (3) type III or immune complex disorders; (4) type IV or cell-mediated immune diseases; (5) type V conditions or gammopathies; and (6) type VI or immunodeficiency disorders. Separate discussions of transplantation immunology and the use of drugs to regulate unwanted immune responses are also included.     

Magnetic resonance imaging findings in histologically confirmed Pug dog encephalitis

The purpose of the study was to describe magnetic resonance (MR) imaging features of histologically confirmed necrotizing encephalitis in four Pugs and to compare those findings with MR imaging characteristics of necrotizing encephalitis in other breeds. All dogs had the following common findings: lesions restricted to the forebrain, both cerebral hemispheres diffusely but asymmetrically affected, lesions affected gray and white matter resulting in loss of distinction between both, most severe lesions in occipital and parietal lobes, lesions were irregularly T2-hyperintense and T1-isointense to slightly T1-hypointense, and no cavitation. There were various degrees of contrast enhancement of brain and leptomeninges. Asymmetry of lateral ventricles and midline shift was seen in one dog each. Two dogs had brain herniation, which may have contributed to the progression of neurologic signs. Hyperintensity on T2-weighted and fluid attenuated inversion recovery images in the hippocampus and piriform lobe was consistent with excitotoxic edema, whereas similar imaging features in other forebrain areas corresponded to areas of inflammation or liquefaction on histopathology. In comparison with necrotizing encephalitis in other canine breeds, Pug dog encephalitis has some unique MR imaging features. Therefore, these characteristics cannot be applied to other breeds, nor should imaging features of necrotizing encephalitis of other canine breeds be used for interpretation of MR images in Pug dogs.     

Chronic inflammatory demyelinating polyradiculoneuropathy with hypertrophy of cervico-thoracal nerve roots in a dog

A case of chronic inflammatory demyelinating polyradiculoneuropathy in a Magyar Vizsla dame, 7 months of age, is described. The neurological deficits such as movement disorders, hyporeflexia and muscle atrophy, were limited to the front legs. The hypertrophied cervico-thoracal nerve roots could be shown by magnetic resonance imaging. The diagnosis was additionally based on clinical findings, the relapsing course, the good response to therapy with prednisolone, the results of electrodiagnostic workup and muscle and nerve biopsy.
