3. By having a look at the age of sucklings till the moment of disease appearance, it is
noticed that, out of 17 cases, 15 cases (88.23%) are recorded for sucklings of 0 - 3
months old, one case (5.88%) for sucklings of 6 -12 months old, one case (5.88%) for
sucklings of 12 - 36 months old; out of the 15 cases involving sucklings of 0-3 months
old, 10 cases (58.82%) are with sucklings of 0-1 month old, two cases (11.76%) with
sucklings of 1-2 months old and three cases (17.64%) with sucklings of 2-3 months
old.
4. Out of 17 cases, six sucklings (35.29%) were feeeded naturally, seven sucklings
(41.17%) were feeded artificially (cow milk) and four sucklings were feeded in a
mixed manner (23.52%).
5. In most cases, that is 88.23% (15 cases), the serious form of disease appeared after the
consumption of well water without sanitary protection, even if the distance
recommended by norms, with respect to possible sources of contamination, was
respected (latrines, manure and fertilizer deposits);
6. Out of 17 probes, seven probes (41,17%) have the nitrate concentration within the
limits imposed by the sanitary norms (under 45mg/l), the rest of them (58.82%) exceed
the maximum admitted concentration (MAC), as it follows: seven probes (41.17%)
have the nitrate concentration between 46-100mg/l and three probes (17.64%) have the
concentration between 101-400mg/l. It is noticed that there were superficial and severe
clinical forms regardless the nitrate concentration in the water;
7. Most of the probes, that is, 15 probes (88.23%) had the nitrite concentration within the
limits imposed by the sanitary norms (0-0.3mg/l), only two probes (11.76%) had a
