acute gastroenteritis (age) has a great impact on children less than five years of age, producing high levels of morbidity and mortality. worldwide, age is mainly related to viruses, mainly rotavirus but human adenovirus (hadv) in particular as an important etiologic agent. among hadv species f, genotypes 40 and 41 are responsible for a high number of diarrhea cases, mainly in children under 2 ...

Randomly amplified polymorphic DNA (RAPD) markers were used to study the genetic diversity and discriminate among 17 unknown genotypes (considered potentially salt tolerant) and 16 known olive cultivars. Fifteen decamer primers which produced 38 reproducible polymorphic bands in the genotypes were selected for analysis. The RAPD markers resulted in 93 distinct banding patterns. Based on either ...

robust information of genetic diversity among bt cotton genotypes is still lacking and availability of several marker systems has prompted us to compare their utility for the detection of genetic diversity. here, we report the comparative efficiency of morphological and molecular markers (est-ssrs and issrs) in determining the genetic diversity among 30 pakistani bt cotton genotypes. three diff...

climate changes due to global warming is affecting world agriculture adversely. heat stress due to global warming has turned to one of the most important factors reducing quantity and quality of plants production such as tomato. despite of wide cultivation of tomato and high temperature effects on its production, unfortunately; research in this area is scarce. this study was conducted to invest...

Paenibacillus larvae is the causative agent of American foulbrood (AFB), a virulent disease of honeybee (Apis mellifera) larvae. In Tunisia, AFB has been detected in many beekeeping areas, where it causes important economic losses, but nothing is known about the diversity of the causing agent. Seventy-five isolates of P. larvae, identified by biochemical tests and 16S rRNA gene sequencing, were...
