Optimized protocols for improving the likelihood of cloning recombinant progeny from Plasmodium yoelii genetic crosses.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Genetic cross is a powerful tool for studying malaria genes contributing to drug resistance, parasite development, and pathogenesis. Cloning and identification of recombinant progeny (RP) is laborious and expensive, especially when a large proportion of progeny derived from self-fertilization are present in the uncloned progeny of a genetic cross. Since the frequency of cross-fertilization affects the number of recombinant progeny in a genetic cross, it is important to optimize the procedure of a genetic cross to maximize the cross-fertilization. Here we investigated the factors that might influence the chances of obtaining RP from a genetic cross and showed that different Plasmodium yoelii strains/subspecies/clones had unique abilities in producing oocysts in a mosquito midgut. When a genetic cross is performed between two parents producing different numbers of functional gametocytes, the ratio of parental parasites must be adjusted to improve the chance of obtaining RP. An optimized parental ratio could be established based on oocyst counts from single infection of each parent before crossing experiments, which may reflect the efficiency of gametocyte production and/or fertilization. The timing of progeny cloning is also important; cloning of genetic cross progeny from mice directly infected with sporozoites (vs. frozen blood after needle passage) at a time when parasitemia is low (usually <1%) could improve the chance of obtaining RP. This study provides an optimized protocol for efficiently cloning RPs from a genetic cross of malaria parasites.
