Micro-organisms in the midgut of tsetse fly larvae.
Two types of micro-organisms were found in the midgut of Glossina morsitans larvae, a large Gram-negative bacterial rod and a small Gram-negative rickettsia-like micro-organism, although the occurrence of the rickettsial type is restricted. The location of these micro-organisms in a small area of the proventriculus of all three larval instars is discussed. The large micro-organisms resemble milk-gland bacteria, and further evidence is presented in support of a milk transmission hypothesis for these micro-organisms.

An analysis of posthospitalization telephone survey data.
As part of a study of patient-centered care outcomes that requires the ability to be interviewed by telephone after hospitalization, 4,600 adult patients on 118 medical-surgical units in 17 midwestern hospitals selected by stratified random sampling were identified as potential subjects. This article describes response-rate differences and reasons for nonparticipation by gender, age, ethnicity, and race. Issues related to understanding and reporting response rates, reducing losses due to ineligibility, dealing with refusals, and tailoring survey approaches to special populations are discussed.
