In this study,808 vimba (Vimba vimba tenella(Nordmann,1840))individuals captured during October 1996-April 1998 from Karacaören I Dam Lake and some properties of reproduction were investigated. In ...the vimba population,age composition varied from 0-VII and 73.51% of the investigated samples belonged to I-II age group. The population was composed of 50.74% females and 49.26% males. It was determined that the reproductive activity of the vimba in the Karacaören I Dam Lake started in the middle of April and continued until the end of June. Sexual maturity ages were found to be II-III for females and II for males. Average egg numbers belonging to age groups varied between 8039 for II age individuals and 28137 for VII age and the mean egg number for each kg fish was 20046 egg/kg.
The aim of this
study is to perform phylogenetic grouping, to detect the virulence associated
genes in Escherichia coli strains
recovered from the urinary tract infections of dogs and cats, and to ...determine
the antibiotic susceptibility profiles, as well. The urine samples from the
animals showing clinical signs of urinary tract infection examined for the
occurrence of E. coli. Phylogenetic
classification of the isolates was performed according to the existence of chuA, yjaA and TSPE4.C2 genes. The isolates were also examined for the
presence of uropathogenecity-associated genes, such as, fimH, sfa1, iut, fyu, hly,
cnf-1, papG and for the diversity of
the papG allelles. Finally, the
antimicrobial susceptibility profiles were examined. E. coli was isolated from 11 (6.08%) of 181 samples. Two isolates
belonged to group A-2, while the remaining isolates belonged to group B-2. hylA was detected in 2 (25%); sfa1, cnf1, papG and papGIII were detected in 3 (37.5%); iutA was detected in 4 (50%); fyuA
was detected in 6 (75%); and fimH was
detected in all of the isolates. Most of the isolates were resistant to
ampicillin while one isolate also showed multidrug resistance. The isolation
rate of E. coli was low in this
study, however, we had a brief data about the phylo-groups and virulence
factors of canine and feline uropathogenic strains.
Rhodococcus equi has been recognized as an equine pathogen since 1923 and is a worldwide pathogen in foals. Up to now, there has been one report on R. equi infection in an Arabian foal in Turkey. We ...report here two cases of R. equi pneumonia diagnosed in Turkish foals. R. equi was isolated from pure cultures obtained from lung abscesses of two dead foals which were sent to the laboratory from distinct stud-farms in the Izmit district, Turkey, due to the increasing mortality of foals with pneumonia. These isolates were analyzed by plasmid and protein profiles: one isolate had an 85-kb type I virulence plasmid and the other was considered avirulent. Virulent R. equi strains possessing an 85-kb type I or an 87-kb type I were isolated from one of the stud-farms with the problem. These results indicate that the stud-farm was contaminated with virulent R. equi.
