Evidence for viable, non-clonal but fatherless Boa constrictors.
Parthenogenesis in vertebrates is considered an evolutionary novelty. In snakes, all of which exhibit genetic sex determination with ZZ : ZW sex chromosomes, this rare form of asexual reproduction has failed to yield viable female WW offspring. Only through complex experimental manipulations have WW females been produced, and only in fish and amphibians. Through microsatellite DNA fingerprintin...
متن کاملViable but Non-culturable Bacteria: Clinical Practice and Future Perspective
In this editorial, the importance of VBNC in clinical practice and future researches interests has been pinpointed. Accurate detection of VBNC, especially for major mentioned pathogens, is the future research gap.

Luring the snakes to climb the ropes by placing a dark cosy refuge at the top, Byrnes and Jayne filmed the animals’ ascents while measuring the tension on the rope as the animals coiled and uncoiled their grip. ‘All the climbing velocities were extremely slow,’ the duo says, ranging from 0.5 to 1 cm s–1 and the snakes only reached their top speeds on the thickest and tensest ropes. All of the s...
متن کاملDetection of Viable But Non-Culturable State of Escherichia coli O157:H7 Using Reverse Transcription PCR
Background and Aims: Many bacteria including Escherichia coli may enter into a viable but non-culturable (VBNC) state under unfavorable stresses, which are unable to be detected by culture-based methods. In this study, the use of Reverse Transcription PCR (RT-PCR) for detection of VBNC state of E. coli O157:H7 was investigated. Materials and Methods: Escherichia. coli O157:H7 was inoculated i...
متن کاملDifferential disease susceptibility in experimentally reptarenavirus infected boa 1 constrictors and ball pythons
26 Inclusion body disease (IBD) is an infectious disease originally described in captive snakes. It has 27 traditionally been diagnosed by the presence of large eosinophilic cytoplasmic inclusions, and is 28 associated with neurological, gastrointestinal and lymphoproliferative disorders. Previously, we 29 identified and established a culture system for a novel lineage of arenaviruses isolated ...
