Monoandry and polyandry in bumble bees (Hymenoptera; Bombinae) as evidenced by highly variable microsatellites.

Highly variable microsatellites enabled a precise assessment of the number of queen matings in the colonies of five bumble bee species. Fifteen of the sixteen microsatellites initially cloned from B. terrestris had flanking regions similar enough to allow PCR amplification on the other Bombus species analysed. The microsatellites selected for intracolony study (four per species) were characterized by a high heterozygosity (0.58-0.93) and a large number of alleles (3-18) in the local populations from which the colonies originated. A single male appeared to have inseminated the queens in the colonies of four species, B. terrestris, B. lucorum, B. lapidarius and B. pratorum, which belong to three subgenera, whereas two of the three analysed colonies of B. hypnorum were polyandrous (minimum number of two and four patrilines, respectively).

[Stevens-Johnson syndrome and pulmonary infection by Mycoplasma pneumonia (author's transl)].

The case-report of an eleven-year-old boy presenting with the association of Stevens-Johnson syndrome and pulmonary symptoms is studied. The course of the disease covered two distinct periods since a one-month interval occurred between the two cutaneo-mucous and pulmonary episodes. Mycoplasma Pneumoniae infection was confirmed by positive seroconversion. The child recovered without sequelae. Indirect immunofluorescence transitorily showed anticytoplasmic antibodies directed against basal epidermic cells. These antibodies were not fixed on the lesions as shown by direct immunofluorescence. The possible connexion between Stevens-Johnson syndrome, Mycoplasma Pneumoniae infection and anticytoplasmic antibodies is under discussion.
