Canis In Plants

Results and discussion
Plants are rich source of bioactive secondary metabolites which could possess antifungal potentials [26]. B. abyssinica was tested against nine diabetic status opportunistic fungi. The results showed the plants extracts only inhibited the growth of 33% of the tested organisms. The essential oil, acetone and aqueous extracts were inactive against the growth of all organisms except M. canis, M. gypseum and T. rubrum. The zones of inhibition were varying from 19.3 to 33.3 mm (Table 1).
The highest activity against the tested fungi was obtained with the essential oil which showed inhibition zones diameter of 33.3 mm against T. rubrum (Table 1). While with acetone extract’s inhibitory activity was with inhibition zones diameters of 32.7 and 28.7 mm against M. canis and M. gypseum, respectively. The lowest activity was obtained with aqueous extract showing inhibition zone diameter of 19.3 mm against M. gypseum (Table 1).
The varying concentrations between 5 and 0.005 mg/ml of the plant extracts and essential oil were tested in order to determine their MIC’s (Table 2). The lowest MIC (2.5 mg/ml) observed was against M. canis and M. gypseum with acetone

abyssinica was evaluated using BST. The toxicity assessment was based on both the inhibition of hatching of the cysts and mortality of the hatched nauplii in different concentrations of plant extracts and controls [22]. The hatching success of A. salina cysts incubated with different plant fractions and controls are shown in Figure 1. The highest hatching success of 23.6% was observed in cysts incubated with the aqueous extracts of B. abyssinica. This was significantly higher than both the positive control (amphotericin B) and the sea water (p < 0.05). The essential oil and the acetone extract exhibited more potent inhibitory effects with hatching success of 11.6 and 12.4% which was significantly higher than positive control but lower than sea water (p <
