A total of 30 water samples and 45 infected fish (carp, Cyprinus carpio) were
collected from freshwater fish farm (Dam of 16 Tishreen-Lattakia) and
analysed bacteriological. Macroscopic examinations of infected fish had showed
the presence of haem
orrhagic skin lesions with brown or red spots throughout
their skin. A total of 64 Aeromonas strains were isolated. The Aeromonas
isolates were distributed as follows: Aeromonas hydrophila (34, 53%), A. caviae
(16, 25%), A. sobria (9, 14%) and (5, 8%) of unidentified aeromonads.
Collectively, Aeromonas spp. are considered as opportunistic causative agents
of human gastroenteritis and other infections. Antibiotic susceptibility tests
were carried on all strains of isolated Aeromonas spp. using twenty different
antibiotics by agar disk diffusion method.
A total of 294 samples of raw-unpasteurized bovine milk and variety of
dairy products (hard cheese, sweet cheese, cream cheese and cream), were
collected from local markets in Lattakia city as well as 44 samples of used water
(clear potable water
collected before used in cheese preparing processes) and
preserving water (turbid water collected from hard cheese preserving tanks).
All samples were analyzed for E.coli O157: H7 detection.
We screening for antimicrobial substances production from marine algae of
Syria. We presented results of ١٦ algal species tested by their lipide and
aqueous extracts agaimst Gram’s negative and positive bacteria, as well as one
fungous species.
T
he lipide not aqueous extracts were the active against Gram’s positive
bacteria especially.
No effect founded on the fongous species. In addition we make comparative
viewing with other studies on other mediterranean contries regarding the same
species of algae tested.
