Latex agglutination test of serum and cerebrospinal fluid （CSF） were negative, while lymph node biopsy showed Cryptococcus neoformans. A diagnosis of disseminated cryptococcal lymphadenitis was made. Then the patient was treated with amphotericin B for 15 days as initial therapy and itraconazole for 6 months as maintenance therapy respectively. The patient received re-examination per 6 months and was followed up for 2 years. Swollen lymph nodes diminished gradually, and no fever or other symptoms were found. Latex agglutination test of serum and CSF were negative throughout the follow-up period, and anti-HIV, syphilis and tuberculosis antibody were all negative.展开更多

The overall sero-prevalence of the investigated equines was 32.7%. Antibodies to T. gondii were found in 38% of 100 horses and 27.6% of 105 donkeys. The titers were 1：2 （4 heads）, 1：4 （11 heads）, 1：8 （13 heads）, 1：16 （17 heads）, 1：32 （5 heads）, 1：64 （10 donkeys） and 1：128 （7 donkeys）. Neither the area nor animal species showed significant differences between the investigated groups. However, age was reported to show significant （P 〈 0.05） effect on equine toxoplasmosis in the Sudan. This is the first report on equine toxoplasmosis in the Sudan.展开更多
