Transmission of chlamydiae by the housefly.
The ability of the housefly to carry viable Chlamydia trachomatis and to transmit a chlamydial ocular infection was studied under laboratory conditions. After feeding flies (Musca domestica) on suspensions of egg yolk sac infected with C. trachomatis serotypes A or B (responsible for hyperendemic trachoma) the agents were reisolated from flies' intestines for up to 6 hours and from their legs a...
متن کاملCircadian rhythm gene regulation in the housefly Musca domestica.
The circadian mechanism appears remarkably conserved between Drosophila and mammals, with basic underlying negative and positive feedback loops, cycling gene products, and temporally regulated nuclear transport involving a few key proteins. One of these negative regulators is PERIOD, which in Drosophila shows very similar temporal and spatial regulation to TIMELESS. Surprisingly, we observe tha...
متن کاملRegulation of Ovarian Ecdysteroid Production in the Housefly, Musca domestica
Highly purified Musca ecdysteroidogenin (ESG) was obtained by extracting housefly heads with an acid-ethanol-urea procedure followed by desalting on a Sephadex G25F column and fractionation on a Sephadex G50F column. Further fractionation was done on a semi-preparative C18 reverse-phase HPLC column with an acetonitrile gradient in 0.1% trifluoroacetic acid in water. Ecdysteroidogenic activity e...
متن کاملPeptidolytic enzymes in different larval stadium of housefly Musca domestica
Four classes of peptidolytic enzymes were described in insects. Many authors have found predominant activity belonging to trypsin-like and chymotrypsin-like activity. By the use specific chromogenic substrates and hemoglobin we have determined enzyme activity in three stages of larval development of housefly. In contrast to above mentioned data we have found, that major part of peptidolytic act...
متن کاملInvestigations on the Mitochondria of the Housefly, Musca Domestica L
1. The ATPase activity of insect mitochondria has been investigated. A comparison was made to determine the distribution and nature of such activity in other isolated fractions of the house fly, Musca domestica L. 2. The ATPase in insect mitochondria is specific in that orthophosphate can be cleaved only from ATP. The Michaelis-Menten constant K(8) = 2.78 x 10(-3)M and V(max.) = 76 micrograms P...
