Use of modified resistogram to type Candida albicans isolated from cases of vaginitis and from faeces in the same geographical area.

Ninety strains of Candida albicans were isolated from vaginal swabs taken by general practitioners from cases of vaginal candidosis. One hundred and nine strains were also isolated from 300 specimens of faeces received from outpatients living in the same geographical area. These strains were typed using a modification of the resistotyping method. We were unable to find any significant differences between the two populations of strains. This suggests that no particular resistotype has an increased ability to cause vaginitis

Rootstock resistance to Fusarium wilt and effect on watermelon fruit yield and quality

The potential of grafted watermelon for resistance to Fusarium oxysporum f.sp. niveum on some Curcurbitaceae, Lagenaria, Luffa, Benincasa and commercial rootstocks was evaluated. Effects of grafting on yield and quality of diseased plants were evaluated. All grafted plants and rootstocks were resistant to the three known races (0, 1, and 2) of F oxysporum f.sp. niveum except watermelon cv. 'Crimson Tide', which was susceptible to race 2. Fruit yield was positively (21-112%) affected by Lagenaria rootstocks but negatively affected (200-267%) by Cucurbita rootstocks when compared with the control. While only minor differences in fruit quality were determined in control and grafted plants on Lagenaria rootstocks, the quality parameters for watermelon grafted onto Cucurbita rootstocks were lower than in the control. The reasons for low yield and quality might be due to an incompatibility between Cucurbita rootstocks and watermelon. These results showed that rootstock influence on disease resistance as well as yield and quality of scion fruit is important in determining the potential use of grafting applications in watermelon
