Sentence examples for mean oocyst density from inspiring English sources

Plasma from the Gambian children donating blood for DMFA experiments was classified as having transmission-blocking activity if either of the following two tests were satisfied: transmission occurred among mosquitoes fed with gametocytes in both AP and CS, and the ratio of arithmetic mean oocyst density was significantly higher in the CS cage than in the AP cage [23], [24].

Transmission success was measured by (i) the percentage of mosquitoes positive for oocyst stage parasites and (ii) the mean oocyst density in gorged mosquitoes.

When mean oocyst density was included in the model there was no additional effect of line or condition (standard vs restricted; Table 1).

This relationship was driven by a strong negative correlation between the mean oocyst density per cage and the proportion of mosquitoes infected with sporozoites (Table 1).

Khan and M. Shahid, unpublished data), which we confirmed in a pilot study (mean oocyst density per mosquito; PbMC1-KO = 376 (± 48.9); Pb820cl1m1 cl1 = 268 (± 34.6); n = 6 cages of 75 mosquitoes per line).

Across all treatment groups, mean sporozoite density was significantly and negatively associated with mean oocyst density, but there were no additional effects of line or condition (Table 1, Fig. 2B).

To examine the effect of oocyst density on mosquito survival and parasite proliferation, we compared the mean oocyst densities per cage with the proportion of mosquitoes infected with sporozoites and the proportion of mosquitoes surviving to day 21 post-infection using generalized linear models with binomial error structures.

Transmission success: the percentage of mosquitoes that were infected was analyzed using logistic regression specifying a binomial error structure with a logit link function and the mean oocyst densities were analyzed with a logistic regression specifying a Poisson error structure with a logarithmic link function (which gives the same fit as a negative binomial, [ 55]).

In addition, we analysed the relationship between mean oocyst and mean sporozoite density per cage with a general linear model on log transformed data.

Differential infection among these two strains was assessed using two outcome measures by comparing two indicators; the percent gut positivity for oocysts /encapsulated parasites (oocyst rate) and geometric mean (GM) number of oocysts/encapsulated parasites per gut (oocyst density) among all the infected mosquitoes as described earlier [17].

The strongest effect was observed for the 100× Iconcentrationtion for both GNF-Pf4492 and KAF246 (mean oocyst count of 0.63 and 1.33, respectively).
