间日疟原虫孢子增殖晚期的扫描电镜观察

以贵州省的4例间日疟病例为供血者,先后感染7批大劣按蚊,用扫描电镜观察蚊虫感染疟原虫后9、11、12d的孢子增殖期。卵囊表面特征与其它疟原虫相似。卵囊壁内侧面粗糙并有许多棘状突起。早期成孢子细胞芽生短锥状子孢子芽,而后渐伸长如棒状而至变为长形。子孢子呈细长形,虫体弯曲,质膜表面光滑,体前端稍平。微孔位于距虫体前端约1/3处。     

白念珠菌厚膜孢子形态发生过程的扫描电镜观察

目的 用扫描电镜观察白念珠菌厚膜孢子在液体培养基中形态发生过程。方法 用改良液体培养基培养白念珠菌厚膜孢子，在不同培养时间收获离心，制备扫描电镜样品，然后观察不同培养时相厚膜孢子及假菌丝的形态。结果 发现培养３小时芽生孢子发芽。５小时芽体延长；７小时次极芽体伸长，假菌丝形成，顶端孢子开始增大；９小时假菌丝延长，厚膜孢子进一步成熟；１６小时厚膜孢子成熟；２４小时见多数厚膜孢子和假菌。结论 用该方法能

Acute endocarditis of the patch caused by Staphylococcus capitis in treated tetralogy of Fallot. An unusual location by an unusual bacterium

We present the case of a 46 year-old male, HCV infected, treated with corrective surgery for tetralogy of Fallot (TOF) immediately after percutaneous closure of the Blalock Taussig shunt. Four months later, the patient had infective endocarditis by Staphylococcus capitis localised on the right side of the patch, treated by oxacillin and gentamycin. The particularity of our report is the unusual location of the acute endocarditis and the bacterium involved: the pulmonary valve is much more likely to be involved in endocarditis in TOF patients and the patch endocarditis has rarely been reported. Moreover, Staphylococcus capitis has never been reported as a cause of acute endocarditis in corrected TOF patients. We believe that antibiotic therapy should be instituted as soon as possible even though an aggressive surgical treatment is mandatory to achieve complete recovery, mainly when clinical condition and inflammation markers do not improve.     

Microsporum nanum. A fourth report of human infection in Brazil]

The authors present the fourth Brazilian case of human Microsporum nanum (M. nanum) infection. A child of nine months old presents cutaneous dorsal lesions compatible with tinea corporis, which appeared one month before. The culture revealed M. nanum. The lesions resolved spontaneously after a month. Epidemiologic investigation in the patient's place of origin identified swine infected by M. nanum, indicating the probable source of the infection.
