Genetic database development for the characterisation of Sicilian sheep population
The most representative sheep in Sicily are Belicina, Comisana, Pinzirita, Barbarescaand the crossbred derived sheep from all this species. In this study, the allelic frequencies of the Sicilian sheep population were investigated. It currently represents the best way to determine the genetic identity and/or family even with limited amounts of sample or when the DNA is degraded. The aim of the study was to provide a reference data bank and to evaluate a microsatellite panel for pedigree analysis as suggested by the International Society for Animal Genetics (ISAG). There are various studies on European sheep, but few datasets were developed on the population of Sicilian sheep. The reference d…
Identification of subspecies and parentage relationship by means of DNA fingerprinting in two exemplary of Pan troglodytes (Blumenbach, 1775) (Mammalia Hominidae)
Four chimpanzee subspecies (Mammalia Hominidae) are commonly recognised: the Western Chimpanzee, P. troglodytes verus (Schwarz, 1934), the Nigeria-Cameroon Chimpanzee, P. troglodytes ellioti, the Central Chimpanzee, P. troglodytes troglodytes (Blumenbach, 1799), and the Eastern Chimpanzee, P. troglodytes schweinfurthii (Giglioli, 1872). Recent studies on mitochondrial DNA show the incorporation of P. troglodytes schweinfurthii in P. troglodytes troglodytes, suggesting the existence of only two subspecies: P. troglodytes troglodytes in Central and Eastern Africa and P. troglodytes verus-P. troglodytes ellioti in West Africa. The aim of the present study is twofold: first, to identify the cor…
Genetic tools discriminate strains of Leishmania infantum isolated from humans and dogs in Sicily, Italy
Background Leishmaniasis is one of the most important vector-borne diseases and it represents a serious world health problem affecting millions of people. High levels of Leishmania infections, affecting both humans and animals, are recognized among Italian regions. Among these, Sicily has one of the highest prevalence of Leishmania infection. Methodology/Principal Findings Seventy-eight Leishmania strains isolated from human and animal samples across Sicily, were analyzed for the polymorphic k26-gene and genotypes were assigned according to the size of the PCR products. A multilocus microsatellite typing (MLMT) approach based on the analysis of 11 independent loci was used to investigate po…
