Epidemiological and clinical characteristics of imported malaria in Bulgaria: A retrospective study of а 21-year period.

Background: Bulgaria, with a high endemicity for malaria in the past, was declared by the WHO as a malaria-free country in 1965. We intended to analyze the epidemiological and clinical implications of imported malaria cases in Bulgaria.

Methods: This is a retrospective cross-sectional analysis of all recorded cases of imported malaria in Bulgaria over a 21-year period (2000-2020).

Prevalence of Intestinal Parasitic Infections among the Bulgarian Population Over a Three Year Period (2015 - 2017).

The aim of the present study is to perform a retrospective analysis of the prevalence of intestinal parasitic infections among the Bulgarian population over the period 2015 - 2017. The study involved all Bulgarians and foreign nationals residing in the country who had been tested for intestinal protozoa and helminths. A total of 23,785 infections have been revealed, of which 17,712 (74.

An inhibitory compound produced by a soil isolate of Rhodococcus has strong activity against the veterinary pathogen R. equi.

Complete genome sequencing of dozens of strains of the soil bacterium Rhodococcus has revealed the presence of many cryptic biosynthetic gene clusters, presumably dedicated to the production of small molecules. This has sparked a renewed interest in this underexplored member of the Actinobacteria as a potential source of new bioactive compounds. Reported here is the discovery of a potent inhibitory molecule produced by a newly isolated strain of Rhodococcus, strain MTM3W5.

Radiation exposure to patients during interventional procedures in 20 countries: initial IAEA project results.

Objective: The purpose of our study was to investigate the level of radiation protection of patients and staff during interventional procedures in 20 countries of Africa, Asia, and Europe.

Subjects And Methods: In a multinational prospective study, information on radiation protection tools, peak skin dose (PSD), and kerma-area product (KAP) was provided by 55 hospitals in 20 mainly developing countries (nine mostly in Eastern Europe, five in Africa, and six in Asia).

Results: Nearly 40% of the interventional rooms had an annual workload of more than 2,000 patients.

An estimate of the influence of the measurement procedure on patient and phantom doses in breast imaging.

This work is aimed to study the variability of dosimetry results owing to various measurement methodologies for breast dosimetry. This is performed in the frame of the development of a national protocol for breast dosimetry. Doses for standard phantom and group of patients were calculated for two mammography systems from the tube output measured with a calibrated ionisation chamber.
