family muridae consists of eight genera and 28 species in iran. this family shows notable variability of karyological features. in this study, karyological data derived from 11 species of 7 genera of this family of iran are presented and compared with previously published accounts. the included species were: mus musculus musculus from gonbad (2n=40, fn=40) and birjand (2n=40, fn=38), rattus nor...

A major PvuII satellite DNA has been cloned from a South American octodontid rodent of the genus Ctenomys (C. porteousi). The satellite monomer, termed RPCS, is 337 bp in size and 42% G + C. Analysis of the nucleotide sequence demonstrates that RPCS is not composed of a series of shorter repeats. RPCS-related sequences were found in 11 of 12 Ctenomys species analyzed by hybridization under high...

Microsatellites or simple sequence repeats (SSRs) are very effective molecular markers in population genetics, genome mapping, taxonomic study and other large-scale studies. Variation in number of tandem repeats within microsatellite refers to simple sequence length polymorphism (SSLP); but there are a few studies that are showed SSRs replication slippage may be occurred during in vitro amplifi...

BACKGROUND Appropriate methodology for storage biological materials, extraction of DNA, and proper DNA preservation is vital for studies involving genetic analysis of insects, bacteria, and reservoir hosts as well as for molecular diagnostics of pathogens carried by vectors and reservoirs. Here we tried to evaluate the utility of a simple filter paper-based for storage of insects, bacteria, rod...

Abstract In some species, populations routinely contain a mixture of lone and group-living individuals. Such facultative sociality may reflect individual differences in behavior as well adaptive responses to variation local environmental conditions. To explore interactions between individual- population-level variabilities species provisionally described facultatively social, we examined spatia...

Of 35 tuco-tucos (Ctenomys opimus) collected in Bolivia, South America, 31 (88%) had eimerian oocysts in their feces at the time they were examined. Eighteen (58%) of the 31 infected animals were concurrently infected with 2 or 3 eimerian species. Four species of Eimeria were recovered and are described as new species based on the characteristics of sporulated oocysts. Oocysts of Eimeria granif...
