PCR verification of mt minichromosomes of Haematopinus suis and H. apri. (A) Lanes 1 and 14: low mass ladder (LML). Lanes 2 and 13: molecular weight marker VII (MWM). Lanes 3–10: amplicons from eight minichromosomes of H. suis (B2311), rrnS-trnC, trnL1-rrnL, nad2-trnI-cox1-trnL2, trnR-nad4L-nad6-trnM, trnK-nad4-atp8-atp6-trnN, trnE-cob-trnV, trnQ-nad1-trnT-trnG-nad3-trnW, and trnD-trnY-cox2-trnS1-trnS2-trnP-cox3-trnA. Lanes 11–12: PCR amplicons from two minichromosomes of H. apri (B2418), rrnS-trnC, and trnQ-nad1-trnT-trnG-nad3-trnW. Genes where PCR primers were designed are in bold. (B) Lane 1: amplicon from trnH-nad5-trnF minichromosome of H. suis (B2311). Lanes 2, 9, and 15: 1-kb ladder. Lanes 3–8 and 10–14: PCR amplicons from seven minichromosomes of H. apri (B2418), trnK-nad4-atp8-atp6-trnN, trnK-nad4-atp8-atp6-trnN, nad2-trnI-cox1-trnL2, nad2-trnI-cox1-trnL2, trnD-trnY-cox2-trnS1-trnS2-trnP-cox3-trnA, trnD-trnY-cox2-trnS1-trnS2-trnP-cox3-trnA, trnE-cob-trnV, trnH-nad5-trnF, trnR-nad4L-nad6-trnM, trnR-nad4L-nad6-trnM, and trnL1-rrnL. (C) Amplicons by pig-lice-specific primers, PGC1F-PGC1R and PG12SF-PG12SR, from the entire nad2-trnI-cox1-trnL2 minichromosome (4.5 kb, Lane 1) and the entire rrnS-trnC minichromosome (3.5 kb, Lane 4) of H. suis. Lane 2: LML. Lane 3: 1-kb Ladder. (D) Amplicons from the coding regions of mt minichromosomes of H. suis and H. apri. Lanes 1 and 11: LML. Lanes 2 and 10: MWM. Lanes 3–4: H. suis from Australia (B2311). Lanes 5–6: H. suis from Poland (B2419). Lanes 7–8: H. apri from Japan (B4218). Lane 9: H. suis from China (B2572).
