1954

INH (Rimifon) und 6-(Sulfanilamido)-2,4-Dimethylpyrimidin (Aristamid) haben eine synergistische Wirkung gegen sensible und gegen streptomycin- und INH-resistente Tuberkelbakterien-Stamme.

Very High Fascioliasis Intensities in Schoolchildren from Nile Delta Governorates, Egypt: The Old World Highest Burdens Found in Lowlands

2021

Quantitative coprological analyses of children were performed in Alexandria and Behera governorates, Egypt, to ascertain whether individual intensities in the Nile Delta lowlands reach high levels as those known in hyperendemic highland areas of Latin America. Analyses focused on subjects presenting intensities higher than 400 eggs per gram of faeces (epg), the high burden cut-off according to WHO classification. A total of 96 children were found to shed between 408 and 2304 epg, with arithmetic and geometric means of 699.5 and 629.07 epg, respectively. Intensities found are the highest hitherto recorded in Egypt, and also in the whole Old World. A total of 38 (39.6%) were males and 58 (60.…

Prions, mad cow disease, and preventive measures: a critical appraisal

2003

In 1996 the first key epidemiological study on bovine spongiform encephalitis (BSE) appeared in the renowned journal Nature [1]. In that article it was estimated that by the year 1996, some 750,000 cows with BSE had entered the food chain in Great Britain. Accordingly, millions of people in GB must have consumed contaminated meat. That same year the first report on a new form of Creutzfeldt-Jakob disease [variant (v) CJD] manifesting in young patients appeared [26]. A connection between this disease and BSE was assumed. In view of the suspicion that the use of meat and bone meal (MBM) had led to the outbreak of BSE, feeding with MBM was banned in the year 1988. The number of new BSE infecti…

Prevalence, Genetic Diversity and Factors Associated with Distribution of Listeria monocytogenes and Other Listeria spp. in Cattle Farms in Latvia

2021

Listeria spp. is a diverse genus of Gram-positive bacteria commonly present in the environment while L. monocytogenes and L. ivanovii are well known human and ruminant pathogens. The aim of the present study was to reveal the prevalence and genetic diversity of L. monocytogenes and other Listeria spp. and to identify the factors related to the abundance of pathogen at cattle farms. A total of 521 animal and environmental samples from 27 meat and dairy cattle farms were investigated and the genetic diversity of L. monocytogenes isolates was studied with WGS. The prevalence of Listeria was 58.9%, while of L. monocytogenes it was −11%. The highest prevalence of L. monocytogenes was found in th…

TEACHERS' SOCIAL AND EMOTIONAL HEALTH INDICATORS IN THE DISTANCE LEARNING SITUATION DURING THE COVID-19 PANDEMIC

2021

There were 3 countries which participated in Erasmus+ project „Supporting teachers to face the challenge of distance teaching” (2020-1-LV01-KA226-SCH-094599) during last year. The aim of the project was to develop a well-functioning digital support system for teachers, promoting socio-emotional health and resilience. The main aim of this research was to outline a research problem on teacher well-being factors in three countries during the Covid-19 pandemic, when teachers worked remotely, and to further explore the problem in a focus group in Latvia. The following is a description of the study that was carried out in Latvia on the problems of teachers' social and emotional health factors dur…

Early Development of the Gut Microbiota and Immune Health

2014

In recent years, the increase in human microbiome research brought about by the rapidly evolving “omic” technologies has established that the balance among the microbial groups present in the human gut, and their multipronged interactions with the host, are crucial for health. On the other hand, epidemiological and experimental support has also grown for the ‘early programming hypothesis’, according to which factors that act in utero and early in life program the risks for adverse health outcomes later on. The microbiota of the gut develops during infancy, in close interaction with immune development, and with extensive variability across individuals. It follows that the specific process of…

Outbreak of CTX-M-15-producing Klebsiella pneumoniae of sequence type 199 in a Latvian teaching hospital

2010

Dumpis U, Iversen A, Balode A, Saule M, Miklasevics E, Giske CG. Outbreak of CTX-M-15-producing Klebsiella pneumoniae of sequence type 199 in a Latvian teaching hospital. APMIS 2010; 118: 713–6. Previous studies on the epidemiology of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in Latvia are lacking. ESBL-producing Klebsiella pneumoniae (n = 32) were subjected to pulsed-field gel electrophoresis (PFGE) and selected isolates to multi-locus sequence typing (MLST). Species identification and susceptibility testing were performed using VITEK2, and sequencing of blaCTX-M was performed in selected isolates. PFGE revealed one major clone (n = 23), with most of the isolates de…

Beeinflussung der Chemoresistenz von Mikroorganismen

1960

8-Chlortheophyllin erhoht die Sensibilitat mancher Mikroorganismen gegen Antibiotica und Sulfonamide. Dies ist abhangig von der Art der Keime und der antibakteriellen Wirkstoffe. Die Vermehrungsgeschwindigkeit und die Mutationsrate von Staphylokokken werden durch 8-Chlortheophyllin vermindert.
