“…In their report on trypanotolerance in cattle, Esievo et al 10 correlated the high level of sialic acid concentration on the erythrocyte surfaces of Ndama cattle to its trypanotolerant feature in sharp contrast to the Zebu breed with low erythrocyte sialic acid and which is trypanosusceptible. The foregoing could thus imply that resistance to NDV Kudu 113 strain infection in indigenous Nigerian ducks and chickens could be due to the presence of very high erythrocyte surface sialic acid concentrations in these poultry species (Figure 1).…”

“…the O-acetylated derivatives are resistant to enzymic cleavage and for such sialic acid types, higher amounts of neuraminidase are required to cleave them from the erythrocytes of infected animals to cause anaemia. [10][11][12] Some indigenous Nigerian poultry species have been reported to harbour the velogenic strain of NDV and yet remain apparently healthy, with no obvious anaemia. 13,14 The indigenous Nigerian animal species are more resistant to infectious disease agents than their exotic counterparts, [15][16][17] a feature attributed to genetic resistance.…”

The erythrocyte surface sialic acid levels of 200 apparently healthy indigenous Nigerian poultry species (pigeons, guinea fowls, ducks and chickens, n = 50 for each species) presented for slaughter at a poultry abattoir in Zaria, Nigeria was determined. Other parameters determined were packed cell volume (PCV) and plasma total protein (TP) concentration. The mean erythrocyte surface sialic acid concentration of pigeons, guinea fowls, ducks and chickens were 7.88 +/- 2.51, 14.6 +/- 2.51, 17.6 +/- 2.51 and 14.2 +/- 2.51 mg mg(-1) respectively. There was a statistically significant difference between the mean erythrocyte surface sialic acid concentration of all the species of poultry sampled (P < 0.05). The high erythrocyte surface sialic acid concentration in the indigenous Nigerian poultry species could be responsible for their resistance to infectious diseases, whose aetiologic agents produce neuraminidases. The mean PCV of the pigeons, guinea fowls, ducks and chickens were 46.22 +/- 6.91, 38.24 +/- 6.91, 36.50 +/- 6.91 and 36.46 +/- 6.91% respectively. The difference between the mean PCV values of pigeons on the one hand and guinea fowls, ducks and chickens on the other was statistically significant (P < 0.05). A negative correlation (r = -0.36, P < 0.05) between mean erythrocyte surface sialic acid concentrations and PCV was observed, i.e. the birds with the highest mean PCV values had the lowest levels of erythrocyte surface sialic acid. There was no correlation between TP concentration and either erythrocyte surface sialic acid concentration or PCV values. It is suggested, based on this study, that erythrocyte sialic acid types in these species should be determined, as the results may be vital in selective breeding.

“…Esievo et al (1982) reported a decline in the amount of sialic acid on the erythrocyte surface in cattle infected with T. vivax leads to anemia because of the process described above. Esievo et al (1986Esievo et al ( , 1990 showed that in N'Dama cattle, concentrations of sialic acid on the erythrocyte surface are higher than in zebu cattle. Because the amount of sialidase and its subsequent hydrolysis is proportional to the concentration of trypanosomes, it has been hypothesized that N'Dama cattle might require a larger number of trypanosomes to reach the same level of erythrocyte damage.…”

“…Earlier works (29,30) had demonstrated that erythrocyte surface sialic acid concentration of trypanotolerant N'dama breed of cattle were five times higher than that of trypanosusceptible Zebu breed. In this study, the overall post infection drop in the PCV of the infected puppies was 36.0% with average daily drop of 0.37% and an overall drop of 3.82% per parasitaemia LEV.…”

The haematology of Nigerian local puppies experimentally infected with the Federe strain of Trypanosoma brucei was studied in a total of six 9-weeks old puppies born to two local bitches. Four were randomly selected and inoculated with about 0.8 x 10 6 of T .brucei subcutaneously and the remaining two served as the uninfected control. The parasitaemia was monitored daily using wet mount microscopy. The packed cell volume (PCV), red blood cell (RBC) counts, total and differential white blood cell (WBC) counts and rates of both red blood cell and white blood cell loss per day and per parasitaemia log equivalent value(LEV) were monitored twice in a week . Parasitaemia was detected in the infected group four days after infection which was followed by an acute disease course, though with low fatality rate in the dogs.
