[The current malariological situation in the countries of western Africa. 1. The Republic of Guinea]. / Sovremennaia maliariologicheskaia situatsiia v stranakh Zapadnoi Afriki. Soobshchenie 1. Gvineiskaia Respublika.

Favorable climatic conditions in the Republic of Guinea are conducive to a high prevalence of infectious and parasitic diseases, responsible for 70% of primary consultations of the population, malaria being diagnosed in 40% of cases. Five landscape malariologic zones were singled out in the country, that are characterized by a certain level of malariogenicity. In the lowland/river and mountain/river zones the parasite index of children aged 2 to 9 varied from 16.4 to 45%, and in some foci it reached 63.1%. Foci in the Guinea-Sudan type wet savanna zone are also referred to meso- and hyperendemic ones. The mountain/forest zones are mainly mesoendemic. Malaria foci in the forest/savanna zone in southern Guinea and in the Sierra Leone northern provinces are hyper- and holoendemic, with the parasite index of children aged 2 to 9 being 76.3-92%.

[Incidence of acute myocardial infarction among Soviet specialists after long-term work in the tropics]. / Zabolevaemost' ostrym infarktom miokarda Sovetskikh spetsialistov, dlitel'no rabotaiushchikh v tropikakh.

The paper presents the results of epidemiological survey of acute myocardial infarction morbidity rates among the Soviet specialists who worked in the Republic of Cuba. A total of 54,765 individuals aged 20-59 years were examined within 10 years. There were 48 cases of acute myocardial infarction (AMI). The morbidity rate in males and females was 1.44 and 0.08 per 1,000, respectively. The morbidity rate was 22.9%; death rate in males and females was 0.28 and 0.08 per 1,000, respectively. The incidence of major risk factors in AMI patients and the relation of the morbidity rates of the specialists to the specific features of their adaptation to an emergency of the tropics were considered. Some trends of practical measures were defined to reduce AMI morbidity rates in specialists moving to the tropics to work.

[Salmonella sensitivity to antibiotics]. / O chuvstvitel'nosti sal'monell k antibiotikam.

Antibiotic sensitivity of 142 strains of Salmonella isolated from patients within 1974-1976 was studied. An increase in the number of the pathogenic microbes resistant to streptomycin was noted. Rare isolates highly resistant to ampicillin were registered. The number of Salmonella sensitive to other antibiotics did not practically change. Levomycetin proved to be a rather active drug in vitro. Still, its use in therapy of salmonelleses did not always produce positive results. The use of levomycetin in clinics is expedient only after careful and repeated estimation of antibioticograms.

[Sensitivity of bacterial flora to antibiotics according to data from a clinical hospital]. / K voprosu o chuvstvitel'nosti bakterial'noi flory k antibiotikam po materialam klinicheskoi bol'nitsy

Antibiotic sensitivity of E. coli O-124, Salmonella and Shigella sonnei isolated from patients during 1968-1972 was studied with the disc method. Increase in the resistance levels to monomycin and neomycin in E. coli O-124 was observed. Sensitivity of Salmonella and Shigella sonnei to some antibiotics did not practically change.
