Antibacterial activities of bitter kola (Garcinia kola) on upper respiratory tract isolates from students of Ambrose Alli University students, Ekpoma, Nigeria

Concerns about the alarming cases of antimicrobial resistance have in recent times, prompted the search for therapeutic alternatives including herbal options. This study therefore, assesses the antibacterial potentials of Garcinia kola extracts on bacterial isolates from the upper respiratory tract of young adult undergraduates. The disc diffusion method was adopted, while phytochemical screening tests (PCST) was performed on the aqueous and ethanol extracts of Garcinia kola to ascertain their active components. The PCST revealed the presence of tanin and steroids, whilesaponin, flavanoids and cardiac glycosides were present only in the ethanol extract. Resin alkaloids were absent in both extracts. A comparative sensitivity test was also performed between Garcinia kola extracts and some conventional antibiotics (Ciprofloxacin and Augumentin). The results revealed that Garcinia kola extracts had inhibitory effect on the test isolates-Staphylococcus, Streptococcus and Klebsiella species; probably due the high tannin and flavanoid contents of the extrcts. Above all, our  findings supports several claims that Garcinia kola has antimicrobial potentials and in turn, suggests that a regulated ingestion of Garcinia kola may to an extent, useful against bacterial infections since it is cheap and readily available.Key words: Antibacterial activities, Bacteria, Garcinia Kola, Upper Respiratory trac

Non-intrusive, in situ detection of ammonia in hot gas flows with mid-infrared degenerate four-wave mixing at 2.3μm

We demonstrate non-intrusive, in situ detection of ammonia (NH3) in reactive hot gas flows at atmospheric pressure using mid-infrared degenerate four-wave mixing (IR-DFWM). IR-DFWM excitation scans were performed in the v2+v3 and v1+v2 vibrational bands of NH3 around 2.3μm for gas flow temperatures of 296, 550 and 820K. Simulations based on spectroscopic parameters from the HITRAN database have been compared with the measurements in order to identify the spectral lines, and an absorption spectrum at 296K has also been measured to compare with the IR-DFWM spectra. The signal-to-noise ratio of the IR-DFWM measurement was found to be higher than that of the absorption measurement. Some spectral lines in the measured IR-DFWM and absorption spectra had no matching lines in the HITRAN simulation. The detection limit of NH3 diluted in N2 with IR-DFWM in this spectral range was estimated at 296, 550 and 820K to be 1.36, 4.87 and 7.06×1016molecules/cm3. The dependence of the NH3 IR-DFWM signal on the quenching properties of the buffer gas flow was investigated by comparing the signals for gas flows of N2, Ar and CO2 with small admixtures of NH3. It was found that the signal dependence on buffer gas was large at room temperature but decreased at elevated temperatures. These results show the potential of IR-DFWM for detection of NH3 in combustion environments

The prevalance of salmonella species among poultry birds in Ekpoma Edo-state, Nigeria.

Fowl typhoid is acute infectious enteritis causing heavy mortality in growers or adult birds; though chicks can be affected. It is caused by the bacterium salmonella enteric Serovars Gallinarum, a member of the family enterobacteriaceae. This research was designed to determine the prevalence of salmonella species among poultry birds in Esan West Local Government Area, Ekpoma, Edo state, Nigeria. A total of 160 faecal samples were collected from Cockerels, Layers, Broilers and Chicks (n=40 each). The samples were then subjected to microbiological analysis using standard biological and biochemical procedures, while the susceptibility patterns of the isolates was determined using the disc diffusion method. Of all the samples examined 6 (3.75%) were positive for Salmonella species, 142 (88.75%) were positive for Escherichia coli and 12 (7.5%) were positive for Staphylococus species. The results showed that the prevalence of Salmonella species was relatively lower than envisaged owing to routine vaccination, but more prevalent among cockerels and chicks. Although, susceptibility pattern of fowl typhoid varies with season, type of poultry bird, immunization status and level of hygiene, it is our recommendation that prompt vaccination of poultry birds is important, while basic hygiene practices should be strengthened.Keywords: Prevalence and poultry Birds, Salmonella species in Ekpoma community

Urinary tract infection among apparently healthy commercial transport workers in Ekpoma and its environs within Edo State, Nigeria.

This study was designed to establish the prevalence of Urinary Tract Infection (UTI) among healthy-male commercial transport workers (taxi drivers and motor-cycle riders) in Ekpoma and its environs within Edo State, Nigeria. Eighty (80) urine samples were collected and using standard laboratory procedures, the prevalence of asymptomatic UTI was determined. The results showed that out of the 80 samples investigated, only 9 (11.3%) of them had asymptomatic UTI with a higher occurrence in samples obtained from taxi drivers and those within the age range of 35 - 45 years. None of the 29 motorcycle riders within the age range of 25 – 34 had UTI while 2 out of the 18 taxi drivers with age 25 – 34 had UTI. For those within the age range of 35 – 45, only 3 out of the 21 motorcycle riders and 4 out of the 12 taxi drivers had UTI respectively. In addition, Klebsiella auregenes and Pseudomonas auruginosa were the predominant isolates; with age playing a prominent factor. Therefore, as road safety campaigns are encouraged for transport workers, concerted efforts must also be made to enlighten them on the need to avoid risky sexual behaviours including drug and alcohol abuse. Keywords: Urinary Tract Infections, Asymptomatic UTI, Personal hygiene, Transport workers

Investigation on Parameters Affecting the Effectiveness of Photocatalytic Functional Coatings to Degrade NO: TiO 2

This paper deals with the degradation of NO by photocatalytic oxidation using TiO2-based coatings. Tests are conducted at a laboratory scale through an experimental setup inspired from ISO 22197-1 standard. Various parameters are explored to evaluate their influence on photocatalysis efficiency: TiO2 dry matter content applied to the surface, nature of the substrate, and illumination conditions (UV and visible light). This article points out the different behaviors between three kinds of substrates which are common building materials: normalized mortar, denser mortar, and commercial wood. The illumination conditions are of great importance in the photocatalytic process with experiments under UV light showing the best results. However, a significant decrease in NO concentration under visible light is also observed provided that the TiO2 dry matter content on the surface is high enough. The nature of the substrate plays an important role in the photocatalytic activity with rougher substrates being more efficient to degrade NO. However, limiting the roughness of the substrate seems to be of utmost interest to obtain the highest exposed surface area and thus the optimal photocatalytic efficiency. A higher roughness promotes the surface contact between TiO2 and NO but does not necessarily increase the photochemical oxidation
