Epidemiologic Study of Vibrio vulnificus Infections by Using Variable Number Tandem Repeats
نویسندگان
چکیده
A 3-year environmental and clinical Vibrio vulnificus survey using simple-sequence repeats typing shows that V. vulnificus biotype 3 constitutes approximately 21% of the bacterium population in tested aquaculture ponds as opposed to approximately 86% of clinical cases. Simple-sequence repeats proved to be a useful epidemiologic tool, providing information on the environmental source of the pathogen.

Molecular Genetic Analysis of the Variable Number of Tandem-Repeat Alleles at the Phenylalanine Hydroxylase Gene in Iranian Azeri Turkish Population
Background: The variable numbers of tandem-repeat (VNTR) alleles at the phenylalanine hydroxylase (PAH) gene have been used in carrier detection and prenatal diagnosis in phenylketonuria families. This study was carried out to analyze VNTR alleles at the PAH gene in Iranian Azeri Turkish population. Methods: In this study, 200 alleles from general population were studied by PCR. Results: The fr...
متن کاملEpidemiological study of Vibrio cholerae using variable number of tandem repeats.
By conventional genetic methods, including pulse-field gel electrophoresis and multilocus sequence typing, most pathogenic, cholera toxin-positive O1 and O139 isolates of Vibrio cholerae cannot be distinguished. We evaluated relationships among 173 V. cholerae isolates collected between 1992 and 2007 from different geographic areas in India by analyzing five variable number of tandem repeat (VN...

Phenylketonuria (PKU) is one of the most common known inherited metabolic diseases. The present study aimed to investigate the status of molecular defects in phenylalanine hydroxylase (PAH) gene in western Iranian PKU patients (predominantly from Kermanshah, Hamadan, and Lorestan provinces) during 2014-2016. Additionally, the results were compared with similar studies in Iran. Nucleotide sequen...

BACKGROUND The Centers for Disease Control and Prevention monitors vibriosis through 2 surveillance systems: the nationwide Cholera and Other Vibrio Illness Surveillance (COVIS) system and the 10-state Foodborne Diseases Active Surveillance Network (FoodNet). COVIS conducts passive surveillance and FoodNet conducts active surveillance for laboratory-confirmed Vibrio infections. METHODS We sum...
