A field survey for chickpea wilt disease Fusarium oxysporum f.sp ciceris was conducted in different provinces of north Syria during 2011 cropping season with the objectives to determine chickpea wilt distribution and factors affecting its develop ment. Two hundred and fifty samples were collected from Alhasakah, Aleppo and Idleb fields. The results showed varying levels of incidence between and within provinces (2-90%), and the highest incidence was recorded in Alfouaa- Idleb (90%). The incidence and distribution of this disease seemed to be affected by many factors especially date of sown and soil kind. The pathogenicity test of 60 isolates related to Fusarium oxysporum on susceptible cultivars Ghab1 was shown that 54 isolates related to Fusarium oxysporum f. sp. ciceris; 32 isolates of them were caused yellowing symptoms and 22 were caused wilting symptoms.
This study aimed to investigate the possibility of rapid identification of isolated bacteria Leuconostoc from Syrian white fresh cheese made of cow and ewe milk using Fourier transform infrared spectroscopy (FTIR). 20 isolates (14 from ewe milk ch eese and 6 from cow milk cheese) were isolated. These isolates were pretasted with PCR technique using specific primers. Results indicated that these isolates are belonged to the genus Leuconostoc and 12 of them are belonged to Ln. mesenteroides species. The results of FTIR technique showed in comparison to device library that all isolates are belonged to genus Leuconostoc, and 4 of these isolates are belonged to Ln. citreum species which could not be identified using PCR method (with the used primers), and helped to identify the following subspecies: Ln.mesenteroides subsp mesenteroides and Ln. mesenteroides subsp dextranicum while PCR technique described them belonging only to a Ln. mesenteroides species. Moreover, FTIR technique was able to give the results within 25 hours, thus it can be used in identification of food bacteria more quickly.
