Comportamento e dieta alimentar de uma espécie de Latrodectus do grupo Mactans (Araneae, Theridiidae) em cativeiro Behavior and diet supply of Latrodectus group Mactans (Araneae, Theridiidae) in captivity

<abstract language="eng">Latrodectus gr. mactans is responsible for 28% of ali accidents provoked by spiders in state of Bahia, Brazil (1980-1990), which makes necessary the study of its manejament. The spiders were captured in Ondina, Salvador, and in Baxio, Esplanada (Bahia, Brazil); they were mantained in captivity, with food supply weekly (Atta sp., larva of Tenebrio sp. and Drosophila melanogaster) with three hours/ offers observation time, during march/95 to april/96. In captivity, the spiders accepted two kinds of food: Atta sp., which seems to be the major item of its diet in natural conditions, and larva of Tenebrio sp., which is not available in natural conditions. Drosophila melanogaster was systematically rejected. The feeding behavior iscomposed by four distinct steps: (1) imrnobilization, (2) inoculation, (3) second immobilization and (4) ingestion. Two kinds of social alimentary behavior are descri-bed. The results indicated that larvae of Tenebrio sp. can be an alternative supply for successfull maintenance of this specie in captivity

Primary tuberculous infection of breast: experiences of surgical resection for aged patients and review of literature

Primary mammary tuberculosis is a rare entity that usually occurs in female of reproductive age. Herein three such patients including two males with ages over 80 years, who underwent surgical resection, are reported. Fine needle biopsy failed to achieve specific diagnosis before surgical operation. All of their conditions got satisfactory improvement and anti-tuberculosis chemotherapy was administered postoperatively. Previous literature related to the epidemiology, diagnosis and treatment for mammary tuberculosis will be also reviewed. Mammary tuberculosis is usually related to breast feeding women and is extremely rare in aged man. The possible mechanisms resulting in this disease in our three patients, including direct extension, reactivation, or transmitted by staffs or peers of the nursing home, would also be discussed
