Microbiological Contamination Associated With The Proximity Of A Refuse Dumpsite To A River Situated In Okada, Edo State, Nigeria, Ebere J. Okafor-Elenwo, Odaro S. Imade, Osazee E. Izevbuwa

Journal of Bioresource Management

This study was performed to evaluate the potential contamination of the Okponha river situated near a dumpsite in Okada, Edo State, Nigeria. Water samples were collected and analyzed for bacteriological and parasitological quality using standard procedures. Isolation and enumeration of bacterial colonies were performed by pour plate technique and the isolated bacteria were identified by standard phenotypic tests. Helminths and protozoa were screened by the direct smear technique. The values of HPC (3.79 ± 0.12 log₁₀ CFU/ml) and TCC (2.20 ± 0.14 log₁₀ CFU/ml) obtained from the river water samples exceeded WHO and NAFDAC recommended limits (≤ 2 …

Effects Of Probiotic Supplementation For Piglets In A Nursery: A Meta-Analysis Ofcontrolled Randomized Studies, Isabella Cristina De Castro Lippi, Larissa Braganholo Vargas, Fabiana Ribeiro Caldara, Henrique Biasotto Morais, Jean Kaique Valentim, Janaína Palermo Mendes

Turkish Journal of Veterinary & Animal Sciences

The objective of this article was to evaluate the effect of probiotic addition on average daily gain and feed conversion on the final piglet nursery phase. This study used a systematic review by meta-analysis to contrast the effect of piglets supplementation without antibiotics (negative control) and with antibiotics (positive control). These results archived a dichotomy that suggests a need for different statistical treatments to evaluate these outcomes obtained by articles. Because of this, a metaanalysis evaluation is justified to identify the animal performance on probiotic or antibiotic supplementation conditions. The use of probiotics improved the feed conversion in the experiments …

Microbial Diversity In Urban Environments: Concern For Antibiotic Resistance, Ality Aghedo, Mangala Tawde, Nazrul I. Khandaker

Publications and Research

We are almost oblivious to the presence of microorganisms in our daily lives, but they exist and come into contact with us all the time. While some bacteria are harmless, and even beneficial, other bacteria can cause infections. A common treatment to bacterial infections is antibiotics and the success of an antibiotic depends on the resistance of the bacteria to the antibiotic. We conducted experiments to identify the types of bacteria that can be found on surfaces or within soil environments that come into contact with a vast number of people on a daily basis and how this can affect …

The Forensic Characterization Of Bacterial And Fungal Organisms In Traditional Chinese Medicine, Julia Grzymkowski, Christopher J. Ehrhardt, Justin L. Poklis, Michelle R. Peace

Undergraduate Research Posters

There has been an increase in use of Traditional Chinese Medicine (TCM) in the United States because they are less expensive and believed to be more effective with less adverse effects in comparison to traditional pharmaceutics. Therefore, sales have increased in the US, despite articles and case studies demonstrating the dangers, such as injury and death, related to TCM, stemming from improper labelling, toxic contaminants, and, in some cases, the presence of pathogenic bacteria. The aim of this study was to perform a survival experiment to demonstrate the importance of proper herbal brewing technique and to conduct a molecular and …

The Application Of Edta-Tris And Chlorhexidine In The Treatment Of Endometritis As A Replacement For Antibiotic Therapy In Cows, Igor Stojanov, Aleksandar Milovanovic, Dragana Ruzic-Muslic, Radomir Ratajac, Milica Zivkov Balos, Nevena Maksimovic, Jelena Apic

Turkish Journal of Veterinary & Animal Sciences

The treatment of reproductive disorders is based on the use of the available antibiotics or antiseptic agents. Prolonged or inadequate antibiotic treatment contributes to the development of antimicrobial resistances, while the use of antiseptics, particularly in high concentrations, leads to endometrial lesions and prolonging of the service period. The present study included monitoring of: 1) reproductive disorders of cows; 2) cytological, morphological, and bacteriological laboratory analyses; 3) susceptibility testing of isolated bacterial and reference strains to the EDTA-Tris (ethylene diamine tetraacetic acid-hydroxymethyl aminomethane) and chlorhexidine (CHX); and 4) an estimate of the time before onset of the new sexual cycle. …

Impact Of Antibiotic Usage On Resistance In Microorganisms; Urinary Tract Infections With E-Coli As A Case In Point, N Sabir, Erum Khan, L Sheikh, Rumina Hasan

Department of Pathology and Laboratory Medicine

Objectives:
In this study, we sought to establish a correlation between consumption of flouoroquinolones in our hospital and the emergence of ofloxacin resistant strains of E. coli in the urinary specimens. Data of all urinary samples, received at Aga Khan University Hospital between January 1995 and December 2002, was retrieved and analyzed. Specimens yielding E-coli as an isolate were included in this study.
Methods:
E. coli Isolates showing >103 colonies were identified using standard microbiological techniques. Antibiotic susceptibility of E. coli was tested using Kirby Bauer disc diffusion method. Antimicrobial usage data, obtained through hospital Pharmacy as unit utilized per …

Petroleum-Utilizing Bacteria: The Biological Line Defense Against Oil Pollution, Steven W. Sokolowski

Biological Sciences Theses & Dissertations

A silica gel-petroleum (SGP) medium was developed which is reliable, approximately the same cost as that of the corresponding agar-based petroleum medium, and can be made sufficiently firm to use in streaking or the spread-plate technique. Advantages of the medium include: the incorporation of all of the major ions of seawater in accordance with Dittmar's Law (the salinity of which can easily be varied from 0 to 35 parts per thousand); a wide workable pH range (5.5 to 11.6); negligable pH drift(~ 0.2 pH units after 166 days); the elimination of all but negligable amounts of syneresis, the ability to …

A Biosystematic Investigation Of Medically Important Yeasts, Nancy Christiansen Ballot

University of the Pacific Theses and Dissertations

The purpose of this study is twofold: (1) conduct an epidemiological survey of yeasts found in clinical material; and (2) suggest an identification scheme that would identify yeasts of medical importance in the shortest possible time.

Metabolic Capabilities Of Sulfur Oxidizing Bacteria And Their Role In Water Pollution, M. I. H. Aleem

KWRRI Research Reports

This report describes investigations into the physiology of microorganisms that are commonly involved in the oxidation of inorganic sulfur compounds. The metabolic activities of these bacteria play a potent role in several fields of economic importance such as strip mining operations, water pollution, corrosion, metallurgy, petroleum technology and soil fertility processes.

The oxidation of inorganic sulfur compounds was studied in the chemolithotrophs Thiobacillus denitrificans, Thiobacillus A₂, Thiobacillus neapolitanus, and a photolithotroph Rhodopseudomonas palustris. Cell suspensions from all of the thiobacilli catalyzed completely the oxidation of sulfide, thiosulfate, and sulfite to sulfate. The oxidation of thiosulfate in R. palustris …
