style='font-size:10.0pt;font-family:Arial'> and established in Syrian
Golden hamsters by Leslie Stauber and his students. In the 70’s, I
had the good fortune of working with Dennis Dwyer on his S1 or S2 strains
of this origin. As widely reported in the literature, this is an excellent
model of visceral leishmaniasis, producing typical clinical outcome
consistently, including invariable death and splenic LD loads of up to 10<sup>10</sup>
per heavily infected spleen. I recall I had difficult time to differentiate
these splenic amastigotes into promastigotes. I did see some motile
promastigotes. While a small number remains viable, many died and appeared
as ghosts during the subsequent incubation. This has led me to suspect selection
of cultivable clones. In some, but not all of these cultures, promastigotes
eventually became ‘adapted’ to the culture conditions and grew,
producing consistently up to ~40 X 10<sup>6</sup> cells/ml in 4-5 days in
successive passages (starting from ~10<sup>6</sup>/ml = ~ 4-5 generation
or replication cycles). The stationary phase promastigotes of these
cultures no longer produce good infection of hamsters, irrespective of the
passage numbers (Isolation of ‘metacyclics” to produce good
infection has since been reported in the literature, if I remember
correctly). These promastigotes are more similar to the Mediterranean L
infantum than to the Indian L donovani of the <st1:place w:st="on">Bihar</st1:place>
region in the sequence of their single-copy protein-coding genes, as
probably already shown by many based on sequencing other genetic sites. <o:p></o:p></span></font></li>

isolates from the diverse clinical forms and they turned to be are highly
homologous. Immunologically they induce different immune responses (TH1/TH2).
We know the vector of L.donovani VL isolates which is P. orientalis, but we
still don’t know the vector of cutaneous L. donovani parasite. We believe
the vector plays an important role in the pathogenesis and the outcome of L. donovani
infection together with the host immune response and may be some of the
parasite virulence factors. We will soon published our data on parasite typing
and host immune responses of the diverse clinical forms. <o:p></o:p></span></font></p>

are dealing with is not very difficult to grow but difficult to maintain, It is
rK 39 positive and as I mentioned in the conversation below that even the
serous exudate from the ulcer is also positive for rK 39 dipstick. In between
because of my relocation to a different institute I was little away from this
work but I intend to resume this work in couple of months. Although in past we
tried to isolate the parasite from sand flies but did not succeed. We will
surely attempt again with the techniques described by you and others.

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

parasites there are different from the familiar Indian L donovani in <st1:place
w:st="on">Bihar</st1:place>. The parasites are refratory to in vitro
cultivation. They do differentiate into promastigotes and may grow a little,
but can't really be subcultured to establish passageable lines. This
is very much reminescent of L infantum in the Mediterranean area. I recall Dr. Sharma
has also found rK39+ dogs, if I remember correctly. If so, Satluj
river valley is endemic to the infantile CL.</span></font><o:p></o:p></p>

from Dr. Sharma showed evidence of L infantum, but also L tropica as well as a
mixture of the two in one sample. This is the same picture we have noted

knowledge on the clinico-epidemiology based on data collected previously by
analyses of cultured promastigotes from one or

patients and reservoir animals.</span></font><o:p></o:p></p>

I agree with Hiro gito, We are working on a focus where the CL is<br>
predominantly caused by L. donovani, and the rK 39 STRIPS GIVE POSITIVE<br>
RESULTS WITH SERA as well as serous exudate from the lesion. The results are<br>
dependent upon species.<br>
