犬前列腺疾病是临床常见的公犬泌尿生殖道疾病,通常发生于老龄公犬,特别是6岁以上的未去势公犬.根据文献报道,主要的前列腺疾病包括:前列腺炎、良性前列腺增生、前列腺囊肿、前列腺脓肿和前列腺肿瘤.前列腺疾病通常会表现出排尿困难、尿淋漓、血尿、便秘,触诊有疼痛反应等临床症状,除此之外前列腺体积、前列腺液的性质,前列腺组织细胞形态等都会发生相应的变化,因此前列腺疾病的诊断除了进行详细的病史调查、全面的一般检查和直肠检查之外,还要进行相应的X线检查、B超检查、前列腺液检查、组织/细胞学检查等特殊的检查方法才能对疾病进行确诊.

Canine prostatic diseases ,w hich are frequent in clinical practice among the genitourinary tract diseases ,are relatively common in male dogs ,especially intact males >6 years old .Common canine pros‐tatic disorders include prostatitis ,prostatic hypertrophy ,prostatic cysts ,prostatic abcessation and prosta‐tic carcinoma .Clinical signs may be similar for many prostatic conditions .Clinical symptoms common to all prostatic diseases include dysuresia ,stranguria ,hematuria ,changes in the comformation of prostatic fluid ,constipation and so on .Different causes of prostatic disease can often not be distinguished by evalua‐tion of history and clinical signs .Additional procedures such as radiography ,ultrasonography ,prostatic fluid evaluation ,prostatic biopsy are essential in making a correct diagnosis .Many medical treatments for prostatic diseases could be selected such as antimicrobial therapy ,castration ,prostatectomy based on the different causes .This article reviewed the different etiologies ,clinical situation ,diagnosis and treatment protocols .

[Objective] The basis of clinical medicine was provided through the investigation of the pathogen of main symptoms of the diseases such as pericarditis,hepatitis and peritonitis in one chicken farm in Anhui Province.[Method] The pathogen of these diseases,cultured after isolated from samples collected,was identified based on the morphological observation,physiological and biochemical tests and 16S rRNA sequence analysis and the clinical drug treatment was conducted according the results of its sensitivity test.[Results] The cultured pathogen was matched with the E.coli in the morphological,physiological and biochemical characteristics,16S rRNA sequence.The test result of the drug revealed that the pathogenic bacteria would be highly sensitivity to Jubizhi,amikacin,ADM and others;moderate sensitivity to cefradine and low sensitivity to nitrofurantoin and gentamicin.The disease would be under control in 3 days after the treatment of Jubizhi.[Conclusion] It was effective way of the clinical treatment of control of chicken E.coli to isolate and identify the pathogen,and to test its sensitivity.
