postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
Maintenance of broad-host-range incompatibility group P and group Q plasmids and transposition of Tn5 in Bartonella henselae following conjugal plasmid transfer from Escherichia coli.
The first demonstration of conjugal plasmid transfer from Escherichia coli to Bartonella henselae is reported. Transconjugants bearing plasmids of incompatibility groups P (IncP) and Q (IncQ), expressing various resistance markers, were generated. Tn5 transposons delivered on suicide plasmids by conjugation showed transpositional insertion into random chromosomal sites.
متن کاملEffect of lipopolysaccharide mutations on recipient ability of Salmonella typhimurium for incompatibility group H plasmids.
Previous investigations of the incompatibility group F, P, and I plasmid systems revealed the important role of the outer membrane components in the conjugal transfer of these plasmids. We have observed variability in transfer frequency of three incompatibility group H plasmids (IncHI1 plasmid R27, IncHI2 plasmid R478, and a Tn7 derivative of R27, pDT2454) upon transfer into various Salmonella ...
متن کاملDiversity of silver resistance genes in IncH incompatibility group plasmids.
Silver compounds are used as antimicrobial agents in medicine and bacteria that develop resistance to silver cations (Ag(+)) pose problems similar to those of antibiotic-resistant bacteria. The first set of Ag(+) resistance genes (sil) was from plasmid pMG101, now assigned to the IncHI incompatibility group. Questions of whether sil genes are unique to pMG101 or are more widely found, and wheth...
