- Nasopharyngeal linguatuliasis known as Halzoun or Marrara syndrome occurs following ingestion of raw or undercooked viscera, including lymph nodes, liver and lung of infected animals. The present study was aimed to investigate the behavioral changes induced by ingestion of Linguatula serrata nymphs in rats. For this purpose, 24 rats were divided into four groups and orally ingested with 0 (control), 15, 30 and 60 L. serrata nymphs, respectively. Sneezing, mouth and tongue movements and mouth opening numbers were counted and the duration of mouth and nose grooming was measured at 10-min blocks for 30 min. Ingestion of 0 (normal saline) number of nymph produced negligible behaviors, whereas 15, 30 and 60 numbers of nymphs increased the above-mentioned behaviors when compared to normal saline (0 nymph) group. In this context, 60 number of nymphs produced more behavioral changes than 15 nymphs. We concluded that ingestion of L. serrata nymphs can produce behavioral changes in orofacial area in rats.
