报道3例由石膏样小孢子菌感染引起的、临床表现不同的皮肤癣病.例1表现为阴囊红色斑片,上覆白色斑点状痂屑,刮去痂屑后见湿润的基底面,患者父亲有同样病变,父子穿用同一件内裤,其父与家猫有密切接触.例2患儿左面部擦伤后局部出现钱币大小红斑,中央为白色痂皮,边缘有渗出伴痒.例3患儿右面部出现钱币大小、边界清楚的红斑,表面有散在的丘疹及少许鳞屑伴痒,偶有家猫接触.3例患者均平素体健.取皮损表面组织直接镜检均发现大量菌丝;真菌培养及鉴定为石膏样小孢子菌.诊断为石膏样小孢子菌所致皮肤感染.3例患者经抗真菌治疗1~2周后痊愈,取得很好疗效. 相似文献

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。 相似文献

95 dermatophyte strains (12 of Trichophyton mentagrophytes, 12 of T. tonsurans, 11 of T. rubrum, 12 of T. megninii, 12 of T. violaceum, 2 of T. schoenleinii, 1 of T. soudanense, 12 of M. canis, 8 of Microsporum gypseum, 1 of M. ferrugineum and 12 of Epidermphoyton floccosum). 1 of Aspergillus niger, 1 of A. ochraceus, 1 of Paecilomyces sp., 1 of Penicillium sp. and 1 of Candida albicans were grown in Sabouraud liquid medium for the study of pH variation over 6 weeks at room temperature and after 4 weeks at 37 degrees C. All the dermatophyte strains alkalinized the medium. The highest pH values after 2-3 weeks' development in room temperature were produced by T. mentagrophytes, M. gypseum and M. canis, and the lowest by T. rubrum and T. violaceum. After the 4th week the alkalinizing activity became more marked for T. mentagrophytes and remained stationary for T. violaceum, In the 5th week the values produced by T. tonsurans were higher than those for M. gypseum, and those for E. floccosum and T. megninii were higher than those of M. canis. A similar behaviour was observed for T. rubrum and T. megninii and for M. canis, M. gypseum and M. ferrugineum. There seems to be a relation between the alkalinizing capacity and the rapidity and amount of the growth. At 37 degrees C both alkalinization and range of variation of the pH values of the medium became more noticeable for the strains of each species. 相似文献

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. 相似文献

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. 相似文献
