| Abstract |
Emergence of chloroquine resistant Plasmodium vivax is a serious obstacle towards malaria control in India. This study elucidates the temporal pattern of antifolate [sulfadoxine-pyrimethamine (SP)] resistance in P. vivax infection by means of genetic polymorphisms, especially analysing the single nucleotide polymorphisms of dihydrofolate reductase (pvdhfr) and dihydropteroate synthase (pvdhps) gene among the field isolates of urban Kolkata Municipal Corporation and rural Purulia region of West Bengal, India. Blood samples were collected from 99 microscopically diagnosed P. vivax patients (52 from Kolkata Municipal Corporation and 47 from Purulia). Parasitic DNA was extracted followed by polymerase chain reaction and sequencing of different codons of pvdhfr gene (15, 33, 50, 57, 58, 61, 64, 117, and 173 codons) and pvdhps gene (373, 380, 382, 383, 384, 512, 553, 585, and 601 codons) were performed to identify the mutations. Prevalence of double mutant dhfr A15P33N50F57 R 58 T61V64 N 117 I173 allele (53.85 %) was observed in Kolkata Municipal Corporation (KMC) whereas in Purulia, wild dhfr A15P33N50F57S58T61V64S117I173 allele was predominated (48.94 %). In pvdhps gene a significant number of isolates (17.31 %) in KMC contained the double mutant S373E380S382 G 383 P384K512 G 553 V585M601 allele. pvdhfr and pvdhps combination haplotype revealed the emergence of quadruple (13.46 %) and quintuple (3.84 %) mutant allele in KMC, which might result in poor clinical response against antifolate drugs. The study reveals that P. vivax parasites in rural Purulia may still be susceptible to SP but additional caution should be taken for treatment of vivax malaria in KMC to limit the blooming of quadruple and quintuple mutant allele in the remainder of the West Bengal, India. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 04 August 2016.
All research outputs
#18,466,751
of 22,881,964 outputs
Outputs from Malaria Journal
#5,055
of 5,579 outputs
Outputs of similar age
#283,793
of 366,909 outputs
Outputs of similar age from Malaria Journal
#125
of 144 outputs
Altmetric has tracked 22,881,964 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 5,579 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.8. This one is in the 4th percentile – i.e., 4% 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 366,909 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 144 others from the same source and published within six weeks on either side of this one. This one is in the 4th percentile – i.e., 4% of its contemporaries scored the same or lower than it.
