This paper dealt with the measurement of some morphology indices in Manis petadactyla and Manis javanica. Measured variables included the body weight, the total body length, the length of head and body, the length of tail, the length of protruding rim of external ear, the length of hind feet, the length of middle claws of fore feet, the length of middle claws of hind feet, the number of rows of scales round mid-body, the number of single flank scales of edge tail. All variables measured were compared respectively between this 2 species. The results indicated that: (1) there were no significant differences in body weight and length of hind feet between this 2 species, but differences in the other variables were extremely significant. (2) The ratio of the length of middle claws of hind feet and fore feet in Manis pentadactyla was less than 1/2 (n=48), while Manis javanica was more than 1/2 (n=15); the length of protruding rim of external ear in Manis pentadactyla was over 10 mm (n=38), whereas Manis javanica was under 10 mm (n=13); the number of single flank scales of edge tail in Manis pentadactyla was not beyond 21 (n=65), and Manis javanica exceeded 21 (n=14). So the ratio of the length of middle claws of hind feet and fore feet, the length of protruding rim of external ear, and the number of single flank scales of edge tail should be regard as distinctive features and taxonomic indices between this 2 species. (3) The relationships between body weight (Y) and the total body length, the length of head and body, the length of tail (X) were positive correlation, and satisfied relation equation Y=aX^b.展开更多
为查明野生动物保护协会送检的1只野生马来穿山甲(Manis javanica)的死亡原因,对其进行剖检,从肺脏组织中分离得到1株病原菌。对分离菌株进行革兰氏染色、生化试验、16S r RNA同源性分析、药敏试验、耐药基因检测、毒力基因检测和小鼠...为查明野生动物保护协会送检的1只野生马来穿山甲(Manis javanica)的死亡原因,对其进行剖检,从肺脏组织中分离得到1株病原菌。对分离菌株进行革兰氏染色、生化试验、16S r RNA同源性分析、药敏试验、耐药基因检测、毒力基因检测和小鼠致病性试验等研究。结果显示:分离菌株在麦康凯、SS、血琼脂和LB培养基上均能生长;革兰氏染色镜检为阴性短杆菌;生化鉴定和16S r RNA同源性分析鉴定该菌株为奇异变形杆菌(Proteus mirabilis),命名为YN2018株;生长曲线表明该菌株在2 h后进入对数生长期,16 h后进入稳定期;该菌株对头孢他啶、头孢噻肟和大观霉素较敏感,对庆大霉素、阿米卡星、阿莫西林、妥布霉素和链霉素中度敏感,对罗红霉素、多西环素和复方新诺明等14种抗菌药物耐药;该菌株含有aadA1、aadB、sul1、sul2和dfrA1耐药基因,并携带有mrpA、rsbA、ureC、zapA、rsmA、hpmA、fliL、ucaA、pmfA和atf A毒力基因;小鼠接种菌株浓度为8.50×10^(8)、1.70×10^(9)、3.40×10^(9)、6.80×10^(9)、1.36×10^(10)cfu/m L的死亡率分别为0、50%、75%、100%、100%;死亡小鼠肝脏和肺脏组织病理切片显示发生局灶性细胞坏死及炎性细胞浸润。分离得到的奇异变形杆菌具有多重耐药和强致病性,可能是导致野生马来穿山甲死亡的原因。展开更多
