The phrase "a strain of an" is not correct in standard written English.
It may be intended to refer to a specific type or variant of something, but it lacks clarity and completeness.
Example: "Researchers discovered a strain of an unknown virus in the samples collected."
Alternatives: "a variant of" or "a type of".
This is akin to assuming the uniformity of a strain of an organism in experimental procedures, and many of us in biology education were trained using those very assumptions in our basic biological research efforts.
Furthermore, a strain of An. stephensi selected for refractoriness to P. falciparum transmission showed no detectable resistance to other Plasmodium species [16].
A strain of An. stephensi selected for refractoriness to P. falciparum transmission showed no detectable resistance to other Plasmodium species [11], [12].
Likewise, a strain of An. arabiensis from Malaria Training Centre, Nazareth, Ethiopia that has been maintained in the laboratory without exposure to insecticides for over 30 years was exposed to the insecticide papers as reference.
In our study, we only tested a strain of An. gambiae that is susceptible to standard insecticides as well as to IVM, as we are not aware of any strains that display IVM resistance.
Metabolic resistance due to mixed function oxidases (MFO) has, for example, undermined attempts at malaria control with deltamethrin residual spraying in southern Africa caused by An. funestus (6 ), and elevated MFO activity in a strain of An. gambiae from Cameroon reduced the efficacy of permethrin-treated netting in laboratory tests (20 ).
This spring, researchers at North Carolina State University identified the culprit: a strain of a parasitic disease called leishmaniasis, which is normally transmitted by sand flies and has killed humans in other countries, but had rarely been diagnosed in the United States.
New research suggests the Cornish Black honey bee is better at dealing with varroa mites, which carry a strain of a disease called deformed wing virus.
A strain of a relatively avirulent organism was genetically engineered to produce IL-10 and was fed to mice with experimentally induced colitis [ 1].
En bloc it is easy to make a case for a strain of mass hysteria.
