Background: Malaria and bacteremia co-morbidity in children cause changes in blood cellular components. Complete blood count from children whose haemoglobin genotypes and bacteremia tests are not known, greatly influence clinical management and interpretation of the haematology results in resource limited healthcare facilities. Objectives: We investigated cellular components from children with bacteremia and malaria co-morbidity. We also analysed the haemoglobin genotypes and bacteria isolates from children with haemoglobin AA, SS and AS in western Kenya. Methods: A total number of 384 children were recruited and complete blood counts done with an automated cell counter. Microscopy was used to determine malaria infections, while bacteremia was determined by blood culture. The haemoglobin genotypes were analysed using the electrophoresis technique. Results: Children with haemoglobin AA and AS had elevated granulocyte counts. Most of the bacteria isolates were from children with malaria and haemoglobin AS. The bacteria isolated from blood culture included non-typhi salmonella, Escherichia coli, Enterobacter cloacae, Staphylococcus aureus, Listeria monocytogenes, Streptococcus pyogenes and Viridans. Salmonella species and staphylococcus aureus were the most prevalent bacteria isolates associated with bacteremia in children with haemoglobin AS and malaria positive. Conclusion: Children with Hb AS have higher chances of malaria and bacterial co-infection which leads to lymphocytopenia, erythrocytopenia and thrombocytopenia. Bacteria responsible for most of malaria co-infections in this region are Salmonella species and Staphylococcus aureus. The malaria and bacterial co-infection in pre-school children initiate differential cellular changes which should be investigated further.

To determine the importance of sinusitis as a cause of orbital cellulitis, the causative organisms and peak age of occurrence, 25 patients hospitalized with orbital cellulitis (ages 8 months to 17 years; 80%, 1-4 years) were studied. Complete blood counts were carried out and radiographic sinus examinations and eye swabs (for culturing) performed prior to antibiotic treatment. Sinusitis was evident in 72% of the patients. Eye swab cultures indicated 80% had streptococcal, staphylococcal or enterococcal infection. The data indicate that sinusitis is an important cause of orbital cellulitis. The most common causative organisms were Streptococcus viridans (44%) and Staphylococcus aureus (32%). Initial antibiotics should therefore cover both organisms.

The successful conduct of disinfection measures largely depends on the availability of veterinary practice a highly efficient, environmentally safe disinfectants. In this regard, finding new highly efficient disinfectant remains relevant. Studies found that the "Polied" (OOO "Razvitie XXI Vek, Russia) can be attributed to the highly efficient and environmentally friendly means. Solutions "Polied" have a high disinfectant activity against smooth and rough surfaces in the laboratory against gram-positive, gram-negative bacteria, mycobacteria and spores of microorganisms. Studies have established that solutions should be "Polied" obezzarajivatmi E. coli (EA 1257) concentrations of 0.1% on smooth surfaces and Staphylococcus aureus concentration of 0.05% in 1 hour from the calculation of 0.25-0.3 litres/m2. Disinfection of rough test surfaces against Escherichia coli and Staphylococcus aureus occurred after treatment with 0,3% solution of 3-hour exposure, at a rate of 0.5 l/m2. It was also found that 1.0% solution "Polied" fully obezzarazhivatel test the surface of mycobacteria (PCs-5) and at double the 0.6% concentration for 24 hours. Disinfection of rough test surfaces contaminated with spores of B. cereus (PCs 96) was achieved with a 4.0% solution at twice the irrigation rate of 0.5 l/m2 at an exposure of 24 hours. Toxicity solutions of the drug "Polied" refer to "moderate" threat (hazard class 3) and low-hazard substances (4 hazard class) when applied to the skin, mucous membranes of the eyes, and inhalation exposure on the respiratory system.

Introduction: In this project, the growth and volatile metabolites profiles of Escherichia coli (E. coli ) and Staphylococcus aureus were monitored under the influence of silver base chemical, nanoparticle and ultra-highly diluted compounds. Materials & Methods: The treatments were done for 12000 life cycles using silver nanoparticles (AgNPs) as well as ultra-highly diluted Argentum nitricum (Arg-n). Volatile organic metabolites analysis was performed using gas chromatography mass spectrometry (GC-MS). The results indicated that AgNPs treatment made the bacteria resistant and adapted to growth in the nanoparticle condition. The use of ultra-highly diluted Arg-n initially increased growth but it decreased later. Also, with the continuous usage of these materials, no more bacterial growth was observed. Results: The most important compounds produced by E. coli are Acetophenone, Octyl acetate, Styrene, 1,8-cineole, 4-t-butyl-2-(1-methyl-2-nitroethyl)cyclohexane, hexadecane and 2-Undecanol. The main compounds derived from S. aureus are Acetophenone,1,8-cineole, Benzaldehyde, 2-Hexan-1-ol, Tridecanol, Dimethyl Octenal and tetradecane. Acetophenone and 1,8-cineole were common and produced by both organisms. Conclusion: Based on the origin of the produced volatiles, main volatiles percentage of untreated sample is hydrocarbon (>50%), while bacteria treatments convert the ratio in to aldehydes, ketones and alcohols in the case of AgNPs, (>80%) and aldehydes, ketones and terpenes in the case of Arg-n (>70%).
