ABSTRACT
Facultative myiasis caused by larval Megaselia sp. is reported in a human in Texas. On two occasions during 24 h, the youth experienced a "crawling sensation deep in [his] throat" which caused him to cough, expelling a living Megaselia sp. larva. The site of the infestation was presumed to be the sinuses or upper respiratory tract. The symptoms resolved upon expulsion of the larvae, and no additional complications were observed in the patient.

A case of human envenomization by a plectreurid spider, Plectreurys tristis Simon, is reported for the first time. The patient was bitten on the calf of the leg and initially experienced pain, edema, and slight pallor at the bite site. Numbness persisted for approximately 1 h in the affected leg. Symptoms resolved without specific treatment, and no significant sequelae were observed.

Nine cases of humans parasitized by the brown dog tick, Rhipicephalus sanguineus (Latreille), are reported. Eight cases occurred during 1989. Seven of the individuals were from an apparent focus of human biting in northern Texas and southwestern Oklahoma, one case was from San Antonio, Bexar County, Tex., and one case was from Homestead Air Force Base, Dade County, Fla. These cases suggest that the role of R. sanguineus in the transmission of the etiologic agent of canine ehrlichiosis and other pathogenic organisms to humans may be underestimated and warrants investigation.
