<DIV><FONT face=Arial size=2>Dear Bob, </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>hybridization takes place in the vector but I am not sure if our finding in Cukurova brings a supporting evidence for this. I can imagine also other scenarios, for example there are seasonal workers in this area, man comming back from army servis etc. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Experimentally we confirmed that at least two local vectors, P. perniciosus and P. tobbi, are highly susceptible to both, "typical" L. donovani (LV9) as well MON1 L. infantum. They are, of course, highly susceptible to the CUK strains and transmit them into mice (Carla Maia presented this in ISOPS this April). For me this is not surprising as P. perniciosus and P. tobbi are Larroussius species and permissive vectors.</FONT></DIV>

<DIV><FONT face=Arial size=2>PS: Just to answer briefly older question about hybrids (I sent this reply before only to Patrick as I feel that discussion is becomming spread too much): based on techniques described in the manuscript we originally thought that these strains are L. infantum (there is nothing about hybrids in the paper). Recently we obtained new data including the whole genome sequence and this allow me to mention that the CUK strain is probably a hybrid.<BR><BR></FONT></DIV>

<DIV>If there are hybrids between <EM>infantum</EM> and <EM>donovani</EM> in Turkey, the cross must have taken place in a vector. Petr, is there a sand fly species there that transmits both parasites? If not, how can there be a hybrid?</DIV>

<DIV><BR></DIV>Dear Petr,<BR><BR>Two comments :<BR>1) I am curious to know how you define a hybrid between L. infantum <BR>and L. donovani, knowing that these species are quite difficult to <BR>differentiate by simple sequence analysis. Is it using the MLST method <BR>described in your paper attached ? Are the genes you are using single <BR>copy or duplicated ? Have you used isoenzymes for confirmation ?<BR><BR>2) Talking of such, I am always puzzled when I see efforts for <BR>correlating molecular and isoenzyme-based phenogramms (Fig. 4, your <BR>article attached). Worse, your text clearly states that the strains <BR>analyzed are "unambiguously distinct from the MON-1 zymodeme (...) of <BR>L. infantum". This is particularly risky, as it is to use zymodeme <BR>names (MON-...) in a phylogenetic reconstruction using other intrinsic <BR>(here molecular) criteria. Indeed, a zymodeme may include different <BR>genotypes and a genotype may theoretically cover several zymodemes. A <BR>zymodeme is nothing else than an "operational taxonomic unit" used for <BR>classification (phenetics) (see the famous paper by Rioux et al. <BR>attached); as such, it has no biological nor evolutionary signification.<BR>Similarly, when you write "Among accessible isolates typed using the <BR>MLST method, our strain is close to MON-188, the L. infantum strain <BR>isolated by Gramiccia (Pratlong et al., 2003)(...)", the MON-... is <BR>abusively assimilated to a given strain (here ISS800), whereas one <BR>zymodeme normally clusters several strains, that might be found <BR>clustered differently using your method or another method.<BR>Another important point is that the MON-... is defined by the <BR>examination of a series of 15 given iso-enzymes, but this is also <BR>dependent upon the technique used (and, to a lesser degree, to the <BR>person/research group who defines it). That is why Rioux et al. <BR>recommended that each identifying center use its own code (such as <BR>MON- for Montpellier or LON- for London). Indeed, MON-188 in <BR>Montpellier migh tbe different from MON-188 in another center if the <BR>system used is not exactly the same.<BR>All this may seem trivial, but there is a real danger, as it slowly <BR>introduces in the minds of our colleagues scientists that different <BR>classifications are equivalent.<BR>I know that I am touching on a question which can yield hours of <BR>debate and thousands of e-mails; so, although I am sure you will want <BR>to reply to this, please note that I do not want to lauch such a <BR>debate online !<BR><BR>Best wishes<BR>Patrick<BR><BR>Professeur Patrick Bastien<BR>Laboratoire de Parasitologie-Mycologie, Faculté de Médecine<BR>UMR MIVEGEC (CNRS 5290 - IRD 224 - Université Montpellier 1)<BR>Centre National de Référence des Leishmania<BR>CHU de Montpellier<BR>39 Avenue Charles Flahault<BR>34295 Montpellier Cedex 5, France<BR><BR>Petr Volf <<A href="mailto:volf@cesnet.cz">volf@cesnet.cz</A>> a écrit :<BR><BR>> Re: [Leish-l] inquiryHi K.P.,<BR>> in Cukurova region, Turkey, cutaneous L. infantum (now it seems that <BR>> we are dealing with L.donovani/L. infantum hybrid) grew very <BR>> poorely if we isolated them from patients.
