Clostridium difficile continues to be one of the most important human health-care associated pathogens, and its role in community-associated infections and in animal disease is being more widely recognised. Following some success in preventing the infection in parts of the world where Clostridium difficile infection (CDI) was unacceptably high, it has begun to decline. However, in other parts of the world it is still increasing, or just being recognised as a problem. We hope that the programme of the 4th ICDS reflects the range of research that is currently addressing the main biological, clinical and veterinary issues of CDIs. The major targets remain the prevention, epidemiology, control and diagnosis of disease, especially of recurrent infections and of outbreaks. The importance of the host has long been recognised as crucial in the susceptibility to infection and research emphasis on pathogenesis and immunology are increasing. Similarly, spores, the infectious agent in CDI are also being investigated in much more detail. Major advances in the genetics of C. difficile have been made, with genetic manipulation becoming generally available and many genome sequences have now been published. We hope, by the end of the meeting participants will be fully updated in all important areas of C. difficile research. ICDS is established as the traditional C. difficile meeting internationally and the venue is also traditionally located in Slovenia. Following the popularity of Bled in 2010, we are here again (Kranjska Gora in 2004; Maribor 2007). The Organizing Committee hopes that you will enjoy the meeting and that it will stimulate new ideas and new collaborations.

  • Phylogeography of Finches and Sparrows
    In: Animal Genetics ISBN: 978-1-60741-844-3 Editor: Leopold J. Rechi © 2009 Nova Science Publishers, Inc. Chapter 1 PHYLOGEOGRAPHY OF FINCHES AND SPARROWS Antonio Arnaiz-Villena*, Pablo Gomez-Prieto and Valentin Ruiz-del-Valle Department of Immunology, University Complutense, The Madrid Regional Blood Center, Madrid, Spain. ABSTRACT Fringillidae finches form a subfamily of songbirds (Passeriformes), which are presently distributed around the world. This subfamily includes canaries, goldfinches, greenfinches, rosefinches, and grosbeaks, among others. Molecular phylogenies obtained with mitochondrial DNA sequences show that these groups of finches are put together, but with some polytomies that have apparently evolved or radiated in parallel. The time of appearance on Earth of all studied groups is suggested to start after Middle Miocene Epoch, around 10 million years ago. Greenfinches (genus Carduelis) may have originated at Eurasian desert margins coming from Rhodopechys obsoleta (dessert finch) or an extinct pale plumage ancestor; it later acquired green plumage suitable for the greenfinch ecological niche, i.e.: woods. Multicolored Eurasian goldfinch (Carduelis carduelis) has a genetic extant ancestor, the green-feathered Carduelis citrinella (citril finch); this was thought to be a canary on phonotypical bases, but it is now included within goldfinches by our molecular genetics phylograms. Speciation events between citril finch and Eurasian goldfinch are related with the Mediterranean Messinian salinity crisis (5 million years ago). Linurgus olivaceus (oriole finch) is presently thriving in Equatorial Africa and was included in a separate genus (Linurgus) by itself on phenotypical bases. Our phylograms demonstrate that it is and old canary. Proposed genus Acanthis does not exist. Twite and linnet form a separate radiation from redpolls.

Canary pet birds are colorful and have pleasing personalities. There is nothing like a peaceful, pretty canary song to unravel nerves at the end of the day. Most types of canaries can sing, though they may not sing all the time. A canary singing is entertaining in itself but they Keeping Canaries some other very desirable traits as well. Adding a pet canary to your home doesn't add an unwelcome burden. They are Keeping Canaries, so keeping canaries takes up very little space. They are also less costly to purchase than many of the larger parrots and some of the other soft billed birds. Canaries are hardy and undemanding, so the canary bird care is pretty easy. They don't pout like a parrot might if you are unable to play with them. And of course, being 'bird-oriented' rather than 'people-oriented', they are unlikely to become finger tame birds. You can simply sit back, relax, and enjoy the antics of these little charmers, and a pretty canary song as well. All domestic canaries originated from the Island Canary Serinus canaria. There are basically three types Keeping Canaries domestic canary today; the Color Canary bred for various canary colors, the Song Canary bred for their canary song, and the Type Canary bred for distinct characteristics of shape, feathering, and size.

  • The Problem of Birds Escaping from Captivity
    THE PROBLEM OF BIRDS ESCAPING FROM CAPTIVITY By DEREK GOODWIN THE acceptance or rejection of rarities and new candidates for the British list is often made difficult by the possibility of their being escapes from captivity. In many cases a certain decision is impossible and the only practical course is to take into considera­ tion all the evidence and decide for the likeliest hypothesis. This article is written principally in the hope of giving assistance in this respect. Secondarily, it will, I hope, stimulate bird-watchers to identify and observe even those species which are obvious escapes. The behaviour and adaptability, or lack of it, of birds which thus find themselves far from their normal range and often far from any suitable environment, is of the utmost interest. continued... 339 340 BRITISH BIRDS [VOL. XUX It would take too long to discuss all the species which have been imported and sold in this country during the past ten years. It must be remembered, therefore, that the birds dealt with in this paper are in the main only those which have been, and in many cases still are being, imported into this country in some quantities. Also, the numbers of the different species imported may fluctuate widely in response to trade, politics and other factors. Probably by the time this appears in print some species not even mentioned herein will be on sale in thousands and some now to be found in every bird-dealer's will no longer be obtainable. In assessing which birds have been most commonly imported since the war I have relied very largely on dealers' advertisements appearing in Cage Birds and other journals.

  • Immanuel Kant's Sparrow
    Immanuel Kant’s Sparrow An integrative approach to canary-like singing House Sparrow (Passer domesticus) DISSERTATION der Fakultät für Biologie der Ludwig-Maximilian-Universität München vorgelegt von Lucie H. Salwiczek München, Mai 2004 durchgeführt am Max-Planck-Institut für Verhaltensphysiologie in Seewiesen 1. Gutachter: Prof. Dr. Wolfgang Wickler 2. Gutachter: Prof. Dr. Gerhard Neuweiler Tag der Abgabe: 05.05.2004 Tag der mündlichen Prüfung: 22.07.2004 Teaching birds to imitate tunes was a popular and lucrative hobby in the 18th century. The Bird Fancyer’s delight was the first collection of tunes, published by the rivals J. Meares (1717) and J. Walsh (1717). From Godman 1954. The most famous house sparrow was Clare Kipps’ Clarence. He produced a remarkable song with two sections (see below): first an introduction with the usual sparrow chirping, though less harsh in tone, followed by a several times repeated four note trills. The second more melodious part „opened with an eight-note trill, followed by a high, sweet, plaintive note. Then, descending by an interval of which I am not quite sure, it rose again to a second trill of eight notes a perfect fourth higher than the first. This theme was repeated several times and sometimes ended abruptly but more often returned to the tonic.“ From Kipps 1956b. III ABSTRACT The adoption of foreign song elements occurs under natural conditions in various songbird species including the house sparrow Passer domesticus, even though it may go largely unnoticed by humans. House sparrows singing canary song have been known by hobbyists for a long time.
