The competitiveness and profitability of the poultry industry in market conditions are hampered by growing problems with the safety and quality of poultry meat. The use of targeted microbial preparations can assist in resolving these problems. Numerous studies of the properties of bacteria of the genus have shown their effectiveness in the practice of poultry farming. The objectives of this study were to identify the effect of various doses of ICIS 96 added to the diet of broiler chickens on their metabolism and to evaluate the productive qualities of the chickens when different doses are used. The experiment was carried out on 72 Cobb-500 cross broiler chickens, divided into 3 groups. Chickens in the first group received a suspension of ICIS 96 containing 1 × 10 cells in 1 mL of sterile saline, at a dose of 0.1 mL per 1 kg of live weight. The second group of chickens received a double dose of enterococcus, that is 0.2 mL of the suspension per 1 kg of live weight per day. The results demonstrated that 0.1 mL of a 1 × 10 per mL enterococcus culture suspension in the poultry diet per 1 kg of live weight per day intensified metabolism and increased the live weight of chickens after 40 d of treatment.

The beneficial properties of probiotics have always been a point of interest. Probiotics play a major role in maintaining the health of Gastrointestinal Tract (GIT), a healthy digestive system is responsible for modulating all other functions of the body. The effectiveness of probiotics can be enhanced by formulating them with prebiotics the formulation thus formed is referred to as synbiotics.

Background: Neonatal sepsis is a leading cause of death in low- and middle- income countries (LMIC). Increasing antibiotic resistance in early onset (< 72 h of life) bloodstream infection (EO-BSI) pathogens in LMIC has reduced the effectiveness of the recommended empiric antibiotic regimen (ampicillin plus gentamicin).
Methods: We retrospectively analysed blood culture-confirmed EO-BSI episodes at nine neonatal units from three central and six peripheral hospitals in the Western Cape Province, South Africa between 1 January 2017 and 31 December 2018.

Technological advancements have allowed the detection of increasingly complex forensic genetics samples, as minimum amounts of DNA can now be detected in crime scenes or other settings of interest. The weight of the evidence depends on several parameters regarding the population and sample-related analytical factors, the latter in a greater number when the DNA amount is considered. This led to the development of probabilistic genotyping software (PGS), able to deal with the associated complexities.

Objectives: Maintained bone health is critical for independent living when aging. Currently, multimodal exercise regimes including weight-bearing exercises with impact are prescribed as optimal for maintaining bone health, while there is less consensus on the effects of resistance training at different intensities upon bone. Here we examined whether bone health was positively influenced by 1 year of supervised resistance training at two different intensities.

Objective: Substance use patterns vary considerably in the general population, yet little is known about patterns before and during pregnancy. The purpose of this study was to describe single substance and polysubstance use (PSU) before and during pregnancy among recent births in the United States (US) and compare exposure patterns.
Methods: We used data from the Pregnancy and Risk Assessment Monitoring System (PRAMS) postpartum survey for 2016-2018 to estimate the prevalence and identify patterns of substance use by participants one to three months before and during pregnancy.
