Review on Microbiological Instruments

The most fundamental skill of microbiology is the use of the microscope. This earliest microscope magnified objects up to 100 times the objects actual size. Today’s 13 microscopes often employ more than two sets. The largest and most accurate microscope is the electron microscope that uses electrons in a focused beam to illuminate objects rather than light. The electrons pass through the specimen being viewed and are electrically focused. The teaching of such an important subject ...

Review on Metal Resistance and Its Association with Antibiotic Resistance in Microbes

Antibiotic resistance is recognized as a major global threat to public health by the World Health Organization. The major driver for the development of antibiotic resistance is considered to be the use, misuse and overuse of antibiotics in humans and animals. Non-antibiotic compounds, such as antibacterial biocides and metals, may also contribute to the promotion of antibiotic resistance through co-selection. This may occur when resistance genes to both antibiotics and metals/biocides are co-...

Review on HIV Virus

Human immunodeficiency virus (HIV) and its subtypes are retroviruses and the etiologic agents of AIDS. Human retroviruses were unknown until the 1980's. HIV belongs to a large family of ribonucleic acid (RNA) lentiviruses.[21] These viruses are characterized by association with diseases of immunosuppression or central nervous system involvement and with long incubation periods following infection before manifestations of illness become apparent. Retroviruses are broadly classified into three ...

Review on Hepatitis E Virus and Related Viruses in Wild, Domestic and Zoo Animals

Hepatitis E is a human disease mainly characterized by acute liver illness, which is caused by infection with the hepatitis E virus (HEV). Large hepatitis E outbreaks have been described in developing countries; however, the disease is also increasingly recognized in industrialized countries. Mortality rates up to 25% have been described for pregnant women during outbreaks in developing countries. In addition, chronic disease courses could be observed in immunocompromised transplant pat...

Review on Microbial Ecology of Fermented Foods and Beverages

Fermented foods and beverages play a significant role in most societies and major contribution in fulfil the protein requirements of large population. There is a relation between microbial diversity of food products and health benefits. Yoghurt is a fermented dairy product, having several health benefits. Yoghurt starter culture consists of a blend of Streptococcus thermophilus and Lactobacillus delbrueckii subsp Bulgaricus. Yoghurt is mainly of two types i.e. set yoghurt and stirred y...

Microbiological Evaluation of Bacteria Species Isolated from Zobo and Kunnu Sold in Olabisi Onabanjo University

ABSTRACTZobo and Kunu drinks are non-alcoholic beverage that is widely produced and consumed in Nigeria.The beverage may possess health risk when contaminated due to method of preparation. Zobo and Kunu drinks were purchased from different sellers in Olabisi Onabanjo University, Ago-Iwoye Ogun State. Physical and chemical analysis of the drinks were carried out, involving pour plate were also employed to isolate bacteria from these drinks. The microbial qualities were determined using pour pl...

The antibacterial effect of the leaf extract of buchhozia coriacea

Abstract: This study was aimed at determining the antibacterial effect of the leaf extract of Buchholzia coriacea (Wonderful Kola) on nasal isolates. Nasal isolates were collected from one hundred students of the Delta State Polytechnic, Ogwash-uku, Delta State. The antimicrobial activity of the methanolic extract of the leaves was assessed against nasal isolated microorganisms (E.coli, Citrobacter species, Klebsiella species, and Proteus species) using the agar well diffusion method. Inh...

Pathophysiology of Ebola virus

ABSTRACT Ebola virus, a member of the Filoviridae virus family, is still an untamed, highly lethal viral pathogen that represents a nightmare for much of central Africa, which is the site of the majority of EBOV outbreaks (Geisbert et al.2010). Unfortunately there has not been a large push in the search for a vaccine as this virus, as deadly as it is, has not impacted a large portion of the world’s population with only 2,300 reported cases of hemmorraghic fever caused by filoviruses. O...

Effects of Palm Oil Processing Waste on Soil

ABSTRACTThe microbiological and physicochemical characteristics of soil receiving palm oil processing waste (POPW) in Abraka were investigated. The effect of palm oil processing waste was tested on loamy, sandy and clay soils. The pour plate technique was used for the isolation of the organisms. The total mean bacterial count ranged from 0.91±0.03log10CFU/g to 6.13±0.06log10CFU/g for loamy soil, 0.90±0.02log10CFU/g to 6.09±0.02log10CFU/g for sandy and 0.72±0.04 to 6.0±0.02log10CFU/g for...

Carriage of β-Lactamase and Antibiotics Resistance Plasmids by Strains of Staphylococcus Aureus Isolated from Hospital Patients in Ekpoma

ABSTRACTA total of 100 subjects were screened for  S. aureus strains, thirty (30) S. aureus isolates were obatained. The carriage of β-lactamase among the 30 isolates was determined by using starch iodine agar plate method. It was found that 19(63.3%) of the S. aureus strains were β-lactamase producing. Plasmid curing of the β-lactamase producing isolates was done using acredine orange supplimented nutrient agar to determine if their β-lactamase producing capability was plasmid mediated ...

STUDIES ON THE ANTIBACTERIAL ACTIVITY OF CASTOR OIL SEED ON SOME SELECTED BACTERIA

ABSTRACT The castor plant is a robust perennial shrub of Euphorbiacaea family.  The seeds are documented to have an antibacterial profile against some bacterial organisms  such as  Escherichia  coli,  Staphylococcus  aureus,  Pseudomonas aeruginosa,    Klebsiella  pneumoniae,  Proteus  vulgaris,  and  Streptococcus pyogenes.  This  study  was  carried  out  to  ascertain  antimic...

Antimicrobial Effect of Natural Honey and Mango Leave on Pathogenic Bacteria

ABSTRACT  Honey has since been found to possess antibacterial property and is therefore employed for wound and gastro-intestinal disease therapy. This study evaluates the antibacterial spectrum and efficacy of honey and compared with tetracycline.  Different concentrations (50, 75 and 100.0 %) of honey were studied in-vitro using Staphylococcus aureus, Klebsiella spp, Escherichia coli and Citrobacter spp. The data obtained showed the inhibitory action of honey with clear zones of inhibition...

Comparative Evaluation of Bacteria and Fungi Diseases Associated with Saccharum officinarum (Sugarcane) in Ethnobotanical Garden of Wesley University, Ondo

ABSTRACTThe comparative evaluation of the bacterial and fungal diseases associated with Saccharum officinarum (Sugarcane) in ethnobotanical garden of Wesley University, Ondo was carried out through different microbial processes. The objectives of this work were to comparatively evaluate bacterial and fungal diseases associated with sugarcane in rainy and dry seasons, isolation and identification of bacterial and fungal diseases associated with sugarcane and development of disease inventory as...
