国内首例阴囊伪膜样星形毛孢子菌感染

目的报道1例由星形毛孢子菌感染引起的伪膜样阴囊感染。方法患者,男,25岁,阴囊白色膜样附着物6周。通过对患者皮损进行真菌镜检、真菌培养,并对获得菌株进行科玛嘉显色培养基鉴定、尿素酶试验、放线菌酮耐受试验和分子生物学分析等实验研究。结果皮损真菌镜检可见大量透明分隔菌丝,真菌培养和分子生物学鉴定为星形毛孢子菌。小培养镜下不但见典型关节菌丝还见典型的多分生细胞。该临床菌株在科玛嘉显色培养基上呈淡蓝色菌落,尿素酶试验阳性,对放线菌酮不敏感。患者口服特比萘芬和外用特比萘芬乳膏,连续2周。停药时皮损消退,真菌学检查阴性。结论由星形毛孢子菌感染引起的伪膜样阴囊感染临床罕见报道,通过对该病例的深入研究,为临床诊疗提供参考依据。     

阴囊皮肤癣菌病患者临床及 真菌学分析

目的探讨阴囊皮肤癣菌病患者的致病菌、临床特征、易感因素及治疗转归等相关因素。方法回顾性分析2007-2017年广州市中山大学附属第三医院经真菌学检查确诊的24例阴囊癣病例,分析患者一般资料、临床特征、发病相关因素、合并其他部位浅部真菌病情况、病原菌及治疗转归等情况。结果 24例阴囊癣患者均为青少年,平均年龄19.6岁,平均病程2.9个月。患者分离皮肤癣菌24株,其中石膏样小孢子菌15株(62.50%)、红色毛癣菌7株(29.17%)和絮状表皮癣菌2株(8.33%)。石膏样小孢子菌主要引起阴囊单纯性感染,临床表现为特征性的白色伪膜样斑片,而红色毛癣菌多引起阴囊及其他部位皮肤癣菌病。结论阴囊癣多见于青少年,石膏样小孢子菌为主要病原菌,其临床表现具有一定特征性。     

石膏样小孢子菌所致面部难辨认癣1例

报道1例由石膏样小孢子菌引起的面部难辨认癣。患者为青年女性,因右眼上眼睑及周围出现浸润性斑块2个月就诊。2个月前发疹部位有烫伤史。经真菌培养和病理检查确诊为“石膏样小孢子菌感染”。予伊曲康唑胶囊口服、外用特比萘芬乳膏1周后痊愈。     

石膏样小孢子菌致脓癣、体癣103例临床分析

石膏样小孢子菌系亲土性皮肤癣菌,因其刺激人体产生的变态反应较强烈,易引起临床误诊误治。为进一步了解石膏样小孢子菌引起的脓癣、体癣的临床症状和鉴别要点。我们对2007年1月～2008年12月来我院皮肤科就诊的由石膏样小孢子菌引起的脓癣、体癣患者103例进行观察和分析,现将结果报告如下。     

15例人畜共患体癣的临床分析

目的通过对生活在同一家庭患有体癣的患者、家庭成员和所养宠物进行观察和分析,探讨人畜共患癣病的常见致病菌种以及治疗方案。方法收集2005年3月～2009年1月就诊于我院因接触宠物而致病的体癣患者,对其宠物的带菌情况进行调查,确诊后给予外用特比萘芬乳膏或联苯苄唑凝胶,未愈者给予口服伊曲康唑治疗。结果共收集15例患者,真菌培养结果显示8例为石膏样小孢子菌,4例为须癣毛癣菌,3例为犬小孢子菌。患者皮损真菌培养结果和所养宠物皮损真菌培养结果一致。按上述方法对患者及其宠物进行治疗,所有患者和10只(3只被丢弃)宠物全部治愈。结论 15例人畜共患体癣中,石膏样小孢子菌感染所致的比例最高,其次是须癣毛癣菌和犬小孢子菌,外用特比萘芬乳膏或联苯苄唑凝胶以及口服伊曲康唑胶囊可以有效治疗此类人畜共患皮肤癣菌病。     

Enzymatic activities of Microsporum canis and Microsporum gypseum strains.

The presence of 11 enzymatic activities, detected by qualitative methods, and 19 enzymes, semi-quantitatively detected by API ZYM system, in strains belonging to Microsporum canis and Microsporum gypseum has been studied. No pronounced differences were noted between Microsporum canis and Microsporum gypseum, although Microsporum gypseum presented in some cases more intense enzymatic activities than Microsporum canis.     

Dermatophytes isolated from symptomatic dogs and cats in Tuscany,Italy during a 15-year-period

Between January, 1, 1986 and December, 31, 2000, dermatological specimens from 10.678 animals (7.650 cats and 3.028 dogs) were examined for dermatophytes. All the animals presented clinical signs of ringworm. Two thousand-four hundred fifty-six of the 10.678 (23%) examined animals scored positive for dermatophytes, 566 out of 3.028 canine (18.7%) and 1890 out of 7.650 feline specimens (24.7%). Microsporum canis constituted 83% and 97% of the isolated dermatophytes respectively in dogs and cats, M. gypseum represented 13% and 2.6% and T. mentagrophytes 5.5% and 0.2%. A sexual predisposition for mycotic infections was not observed. The animals with less than 1 year of age were more frequently infected. Canine toy breeds showed a significantly higher (P < 0.001) prevalence of infections by M. canis. Microsporum gypseum was mostly recorded from sporting (hunting) breeds [such as T. mentagrophytes (6.7%)]. Microsporum canis was isolated from long-haired cats with a ratio of 2:1 versus short-haired cats, while M. gypseum and T. mentagrophytes were never recovered from Persian cats. The annual distribution of the infections in dogs showed a significantly higher incidence for M. gypseum in summer versus winter and spring, while the recovery rate of M. canis from cats was very significantly higher in fall and winter than in summer and spring. Trichophyton mentagrophytes did not show a similar seasonal distribution.
