Emaciation, white faeces, hole-<strong>in</strong>-head disease<br />
Symptom 6:<br />
Emaciation, white faeces, and hole-<strong>in</strong>-head disease.<br />
Advanced hole-<strong>in</strong>-head disease <strong>in</strong> a Crenicichla sp. "X<strong>in</strong>gu" (above). Wild-caught green<br />
discus (Symphysodon aequifasciatus aequifasciatus) (below), emaciated as a result of a<br />
massive attack by Hexamita.<br />
Cl<strong>in</strong>ical picture: The various cichlid species <strong>in</strong> particular are<br />
prone to illnesses where s<strong>in</strong>gle specimens feed less well, lose condition,<br />
and become emaciated. On closer <strong>in</strong>spection <strong>the</strong> faeces<br />
are sometimes seen to be white and hang from <strong>the</strong> anus <strong>in</strong><br />
"str<strong>in</strong>gs". Sometimes pitted holes appear <strong>in</strong> <strong>the</strong> sk<strong>in</strong> above <strong>the</strong><br />
eyes, extend<strong>in</strong>g <strong>in</strong>to <strong>the</strong> tissue below.<br />
Cause: The ma<strong>in</strong> causes of this disease syndrome are as a<br />
rule unicellular parasites of <strong>the</strong> flagellate group, <strong>in</strong> particular<br />
Hexamita, but also Cryptobia and Protoopal<strong>in</strong>a (which primarily<br />
parasitises discus). These parasites are found <strong>in</strong> <strong>the</strong> gut, and <strong>in</strong><br />
particularly severe cases <strong>in</strong> <strong>the</strong> liver and spleen as well. The holes<br />
that appear dur<strong>in</strong>g hole-<strong>in</strong>-head disease are usually diagnosed<br />
as be<strong>in</strong>g caused by Hexamita.<br />
Treatment: Prompt treatment with amtra medic 5 can prevent<br />
<strong>the</strong> parasites from spread<strong>in</strong>g from <strong>the</strong> gut to <strong>the</strong> liver and spleen,<br />
and hence avoid <strong>the</strong> associated severe progressive wast<strong>in</strong>g and<br />
emaciation. Hole-<strong>in</strong>-head disease, <strong>in</strong> which <strong>the</strong> flagellates are<br />
only one of a number of causes, should also be treated with<br />
amtra medic 5 but <strong>in</strong> comb<strong>in</strong>ation with m<strong>in</strong>eral-rich food<br />
(eg amtra sano basic).<br />
Prevention: Intest<strong>in</strong>al flagellates will f<strong>in</strong>d an environment suitable<br />
for uncontrolled proliferation only when <strong>the</strong> normal <strong>in</strong>test<strong>in</strong>al flora<br />
has been compromised. The commonest cause of this is unsuitable<br />
and <strong>in</strong>digestible food. Regular feed<strong>in</strong>g with <strong>the</strong> m<strong>in</strong>eral-rich<br />
and easily digestible natural food materials conta<strong>in</strong>ed <strong>in</strong> amtra<br />
sano can largely prevent Hexamita <strong>in</strong>fection. Even <strong>in</strong> <strong>the</strong> case<br />
of a pre-exist<strong>in</strong>g <strong>in</strong>fection <strong>the</strong> progress of <strong>the</strong> disease can be<br />
significantly and positively <strong>in</strong>fluenced by appropriate feed<strong>in</strong>g.<br />
