Detection of seasonal asymptomatic dermatophytes in Van cats

Abstract The Van cat is a domestic landrace found in the Van province of eastern Turkey. In this study, we aimed to determine the seasonal carriage of dermatophytes in Van cats without clinical lesions. A total of 264 hair specimens were collected from clinically healthy cats in and around the Van Province. Of these samples, 30.3% were obtained in spring, 30.6% in summer, 16.6% in autumn, and 22.3% in winter; 45.1% of samples were from male cats and the rest from female ones. Of the studied cats, 118 were younger than 1 year, 78 were 1–3 years old, and 68 were older than 3 years. The specimens were subjected to direct microscopic examination with 15% potassium hydroxide and cultured on Sabouraud dextrose agar and dermatophyte test medium supplemented with cycloheximide and chloramphenicol. Dermatophyte identification was carried out based on macroscopic and microscopic colony morphology, urease activities, in vitro hair perforation test, growth at 37 °C, and pigmentation on corn meal agar. Dermatophytes were isolated from 19 (7.1%) of the 264 specimens examined. The most frequently isolated fungi were Trichophyton terrestre (4.1%), followed by Microsporum gypseum (1.1%), M. nanum (1.1%), and T. mentagrophytes (0.7%), and these fungi may represent a health risk for humans in contact with clinically healthy Van cats. M. canis was not isolated from any of the specimens. Our results show no significant (p > 0.05) association between carriage of dermatophytes and the gender of cats. The carriage rate of dermatophytes was high in spring and winter, and the only possible risk factor for infection was age of the animal.

The informed consent status for surgery patients in eastern Turkey: a cross-sectional study.

This study assesses the quality of the informed consent process and satisfaction with the informed consent process, for surgery patients in Turkey. Four hundred and eighty three patients were interviewed after their surgeries. More than half of the patients were satisfied with the information on eight issues that pertained to the informed consent process. A majority of patients (91 per cent) were satisfied with the information regarding why an operation necessary. However, only 205 of 483 patients(42 per cent) indicated that they had received sufficient information on the potential side effects and complications of surgery. Patients' educational level and the type of surgery--urgent or elective--were associated with the satisfaction status.

Exact tandem repeats analyzer (E-TRA): a new program for DNA sequence mining.

Exact Tandem Repeats Analyzer 1.0 (E-TRA) combines sequence motif searches with keywords such as 'organs', 'tissues', 'cell lines' and 'development stages' for finding simple exact tandem repeats as well as non-simple repeats. E-TRA has several advanced repeat search parameters/options compared to other repeat finder programs as it not only accepts GenBank, FASTA and expressed sequence tags (EST) sequence files, but also does analysis of multiple files with multiple sequences. The minimum and maximum tandem repeat motif lengths that E-TRA finds vary from one to one thousand. Advanced user defined parameters/options let the researchers use different minimum motif repeats search criteria for varying motif lengths simultaneously. One of the most interesting features of genomes is the presence of relatively short tandem repeats (TRs). These repeated DNA sequences are found in both prokaryotes and eukaryotes, distributed almost at random throughout the genome. Some of the tandem repeats play important roles in the regulation of gene expression whereas others do not have any known biological function as yet. Nevertheless, they have proven to be very beneficial in DNA profiling and genetic linkage analysis studies. To demonstrate the use of E-TRA, we used 5,465,605 human EST sequences derived from 18,814,550 GenBank EST sequences. Our results indicated that 12.44% (679,800) of the human EST sequences contained simple and non-simple repeat string patterns varying from one to 126 nucleotides in length. The results also revealed that human organs, tissues, cell lines and different developmental stages differed in number of repeats as well as repeat composition, indicating that the distribution of expressed tandem repeats among tissues or organs are not random, thus differing from the un-transcribed repeats found in genomes.
