The electrophoretic karyotype of Trichomonas vaginalis isolates was determined by contour-clamped homogeneous electric field electrophoresis. Six chromosomal bands ranging between 50 kbp and 6 Mbp were reliably resolved by our separation method. Trichomonad chromosomes fell into 3 distinct size classes. The 3 maxichromosomes were approximately 5,700, 4,700, and 3,500 kbp. Two intermediate-sized chromosomes were approximately 1,200 kbp and 1,100 kbp. A minichromosome was approximately 75 kbp. The same size and number of chromosomes were present in 15 T. vaginalis isolates obtained from different geographic regions, reinforcing the idea of a highly conserved karyotype among trichomonal isolates worldwide.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 October 2008.
All research outputs
#12,345,312
of 34,365,356 outputs
Outputs from Journal of Parasitology
#809
of 3,656 outputs
Outputs of similar age
#22,736
of 53,236 outputs
Outputs of similar age from Journal of Parasitology
#3
of 8 outputs
Altmetric has tracked 34,365,356 research outputs across all sources so far. This one is in the 38th percentile – i.e., 38% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,656 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.5. This one is in the 28th percentile – i.e., 28% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 53,236 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 7th percentile – i.e., 7% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 8 others from the same source and published within six weeks on either side of this one. This one has scored higher than 5 of them.
