Sentence examples for mean worm burden from inspiring English sources

How do long-term temperature increases affect the mean worm burden in the population?

The parameters of the (negative-binomial) distribution of worms at equilibrium are the mean worm burden W = 20 and the clumping parameter k = 0.34 [27].

As before, the responses to control of disease prevalence were qualitatively similar to those of mean worm burden, so we only present the latter results here.

A sensitivity analysis was conducted where each parameter at each temperature was increased by up to a factor of 10 and the impact on mean worm burden per individual and prevalence measured (note that the results for these are qualitatively similar, so only the results for mean worm burden are presented here).

The mathematical relationship between host age and mean worm burden [11] is consistent with a very weak and rapidly waning naturally acquired immunity, with strength Ω<0.003 and immunological memory 1/ω<3 years.

Overall, these results show a clear advantage to targeting both intermediate vectors and the human population over treating humans alone; indeed, it appears adopting a human-only treatment is very unlikely to be effective in reducing either the regional prevalence or mean worm burden of schistosomiasis at increased temperatures.

The model predicts that mean worm burdens in humans are greatly affected by ambient temperature, rising to a peak at 30°C and then falling sharply at 35°C (Fig. 2).

However, the disease prevalence in humans remains almost constant over the temperature range of 20 35°C (Fig. 2), suggesting that although increases in long-term mean ambient temperature may lead to an increase in mean worm burdens and associated increases in morbidity and even mortality of infected hosts, the number of infected people is unlikely to change greatly.

The heaviest mean worm burdens were seen in untreated groups (US and UM) (Table 2).

All sections of the gastrointestinal tract had high mean worm burdens, varying from 1370.08 to 2862.68 nematodes.

Mean worm burdens of tracer lambs that grazed with the experimental sheep on the summer pastures are shown in Table 5.
