Öğe A STUDY ON MICROFLORA IN ORAL AND CLOACAL OF FRESHWATER TURTLES (Emys orbicularis Linnaeus, 1758 and Mauremys rivulata Valenciennes, 1833) FROM KAVAK DELTA (CANAKKALE)(Parlar Scientific Publications (P S P), 2012) Hacioglu, Nurcihan; Dulger, Basaran; Caprazli, Tugce; Tosunoğlu, MuratDeltas are reservoirs for important plant and animal species and have a vital role in maintaining sustainability of ecological balance. In addition, because of anthropogenic pressure they are recognized as natural habitat of pathogenic microorganisms and infectious diseases caused by these bacteria are dangerous to aquatic animal's health and could potentially affect several species as well those are endangered. This study aims to determine the micro-flora of freshwater turtles (Emys orbicularis Linnaeus, 1758 and Mauremys rivulata Valenciennes, 1833) and sensibilities of these turtles against isolated pathogenic bacteria. Furthermore the investigation was conducted to characterize diseases causative agents. Their risks to animal and human health are difficult to carry out, especially for some turtle species. The results showed that the isolates were identified as Vibrio spp. and Proteus spp. So, these bacteria are the main pathogens isolated from E. orbicularis and M. rivulata. These data appoint the importance of epidemiological surveillance and microbiological monitoring and reinforce the need to implement environment protection programs especially for the threatened turtle species (E. orbicularis).Öğe A study on microflora in oral and cloacal of freshwater turtles (Emys orbicularis Linnaeus, 1758 and Mauremys rivulata Valenciennes, 1833) from kavak delta (Canakkale)(2012) Hacioglu, Nurcihan; Dulger, Başaran; Caprazli, Tu?çe; Tosunoğlu, MuratDeltas are reservoirs for important plant and animal species and have a vital role in maintaining sustainability of ecological balance.

A total of 153 bacteria have been successfully isolated from cloaca and oral samples of the aquatic amphibians and reptilians which were found, namely, Aeromonas sp. (n = 29), Plesiomonas sp. (n = 7), Vibrio sp. (n = 12), Citrobacter sp. (n = 12), Enterobacter sp. (n = 11), Escherichia sp. (n = 22), Klebsiella sp. (n = 22), Edwardsiella sp. (n = 6), Hafnia sp. (n = 1), Proteus sp. (n = 19), Providencia sp. (n = 8), and Pseudomonas sp. (n = 4). In terms of antibiotic and heavy metal susceptibility testing, each isolate was tested against 12 antibiotics and 4 metals. There was a high incidence of resistance to cefoxitin (46.40 %), ampicillin (44.44 %), erythromycin (35.29 %), and a low incidence of resistance to gentamicin (6.53 %), kanamycin (8.49 %), chloramphenicol (9.15 %), and cefotaxime (10.45 %). The multiple antibiotic resistance index of each bacterial species indicated that bacteria from raised amphibians and reptiles have been exposed to tested antibiotics, with results ranging from 0 to 0.58. Most isolates showed tolerance to different concentrations of heavy metals, and minimal inhibition concentrations ranged from100 to > 3,200 mu g/mL. According to these results, a significant occurrence of bacteria in the internal organs of reptiles and amphibians, with a high incidence of resistance against antibiotics and heavy metals, may risk aquatic animals and the public health. These data appoint the importance of epidemiological surveillance and microbiological monitoring and reinforce the need to implement environment protection programs for amphibian and reptile species.Öğe Evaluation of Antimicrobial Activity of Some Mosses From Turkey(Asian Journal Of Chemistry, 2009) Dulger, Basaran; Hacioglu, Nurcihan; Uyar, GurayEthanolic extracts obtained from 5 Byrophyte species (Platyhypnidium riparioides (Hedw.)

In the present investigation, the mean average value (mean +/- SD) of the stream temperature, dissolved oxygen (DO), biochemical oxygen demand (BOD(5)), pH, electrical conductivity (EC), total coliform (TC) and faecal coliform (FC) were noted as 15.533 +/- 0.199 degrees C, 8.332 +/- 0.253 mg/L, 136.60 +/- 2.51 mg/L, 7.5078 +/- 0.0427, 869.93 +/- 3.72 mu S/cm, 39381 +/- 7952 MPN/100 mL and 42500 +/- 7072 MPN/100 mL, respectively. Based on results of comparison of data with WPCR, it is seen that waters of Biga Stream at the sites 1, 2 and 3 belonged to Class 4, for parameter BOD5 and faecal coliform and belonged to Class 3 for parameter total coliform. We conclude that there is a great potential risk of infection of waters from the Biga Stream.Öğe Monthly variation of some physico-chemical and microbiological parameters in Saricay Stream (Canakkale, Turkey)(2010) Hacioglu, Nurcihan; Dulger, BasaranWater samples were collected from three different sites of the Saricay Stream (Canakkale, Turkey) in the months of October 2007 - September 2008 for the analyzing of some physico-chemical and microbiological parameters of the stream.
