Abstract: Xenorhabdus is a bacteria genus of the family Enterobacteriaceae. Bacteria of this genus form a mutualistic relationship with Steinernema entomopathogenic nematodes. More so, their antimicrobial production serves as a potential source of novel antibiotics in the wake of growing antimicrobial resistance. This study aimed to establish the phylogenetic relationship of three Xenorhabdus isolates to the 24 described species of the genus based on the 16s rRNA gene. Secondly, it aimed to ...
Abstract: Sustainable mango production will rely increasingly on alternatives to conventional chemical insecticides that are environmentally friendly for the management of fruit flies. The use of microbial control agents such as fungi in pest suppression is considered suitable since micro-organisms usually exert low environmental impact and are target specific. Application methods of bio-pesticides in the environment, which use minimal amount of inoculum is currently under improvement from i...
Abstract: The possibility of adaptation to host resistance by field strains of R. appendiculatus was investigated by comparing the feeding and breeding performance of two field strains with a laboratory strain (Muguga) which has been bred and maintained for about 30 years on susceptible rabbits. Results have shown that the laboratory strain has smaller eggs and smaller unfed larvae, nymphs and adults than the field strains. When fed on susceptible rabbits the laboratory strain females laid e...

The wrong and excessive use of antibiotics in the poultry industry poses a threat to public health due to the release of antibiotic-resistant bacteria into the environment and its impact on consumers of poultry products. This research aimed to investigate the occurrence and patterns of antibiotic resistance found in Klebsiella species isolated from poultry faeces in Owo metropolis. Fecal samples were collected from healthy broilers in three privately-owned poultry farms in Owo, using sterile ...
Background and Objectives: Abuse and indiscriminate use of antibiotics, prolong hospital admission, travel history, organ transplants, immunocompromised conditions and age are parts of the factors that contribute to development of antibiotic resistance and intestinal carriage of Extended Spectrum Beta-Lactamases (ESBL) Enterobacteriaceae. These bacteria affect the course and outcome of an infection and continue to pose a challenge to infection management worldwide. This study was carried out ...
Beta-lactamase enzymes e.g. metallo β-lactamases (MBLs) that produces Gram-negative bacteria is no doubt one of the widely spread resistance strategies which was geared by these group of bacteria towards β-lactam drugs. MBLs hydrolyzes bacteria and resist carbapenems. This study aimed at determining the antibiogram and the production of MBLs by Klebsiella species from poultry feaces in Owo metropolis. From Poultry feaces aseptically collected Klebsiella species was isolated using MacConkey ...
One of the most common sources of protein globally is catfish which are artificially reared in Nigeria. Pseudomonas species are opportunistic in nature, pathogenic Gram negative bacteria and may build multidrug resistant which can cause a serious threat to public health when present in environmental samples. This research was meant to determine the antibiogram of Pseudomonas species and its prevalence isolated from catfish ponds in Owo metropolis. The pond’s water samples were aseptically c...
Pseudomonas species are most available pathogenic Gram negative bacteria in environmental samples. They are resistant to several drugs, opportunistic pathogen and their presence in the environment poses threat to the public health. The ability of microorganisms to survive in the presence of antimicrobial agents at a situation that can kill or enhance their growth is known as antimicrobial resistance. This has become a serious threat globally, which makes the treatment of infections in humans ...
Pseudomonas species are common pathogenic Gram negative bacteria frequently found in environmental samples. Pseudomonas species are responsible for different healthcare-associated infections and are inherently resistant to many commonly used antibiotics. This study was aimed at isolating; identifying and determining the antimicrobial susceptibility pattern of Pseudomonas species isolated from pig feaces in Owo metropolis. Freshly passed feacal samples were aseptically collected from apparentl...
This study was carried out to determine the antibiotic susceptibility profile and the production of metallo-β-lactamase (MBL) by Escherichia coli isolated from cow dung in Owo metropolis. The isolation of Escherichia coli was done using MacConkey agar and Eosin Methylene Blue Agar and was conventionally characterized. Antimicrobial susceptibility test of the isolates were by disc diffusion method against ceftazidime (30 μg), cefuroxime (30 μg), gentamicin (10 μg), cefixime (5 μg), ofloxa...
ABSTRACT This study was carried out to determine the antimicrobial activity of seed oil of Moringa oleifera and garlic against some selected food-borne microorganisms (Staphylococcus aureus, Escherichia coli, Salmonella spp and Pseudomonas aeruginosa) using disc diffusion method. The antibacterial assay results shows that the seed oil of Moringa oleifera was inactive against all the tested organisms, even at 100 % concentration. In contrast, garlic oil was found to be active against all the t...
ABSTRACT The use of traditional medicine to treat infection has been practiced since the origin of mankind, and honey produced by Apis mellifera is one of the oldest traditional medicines considered to be important in the treatment of several human ailments. However, differently processed honeys exhibit different antibacterial activities, thus this study was aimed at investigating the antibacterial activity of fortified honey and comparing the antibacterial activities of fortified with the un...
ABSTRACT The antibacterial activity of the extract of Ocimum gratissimum was determined against Escherichia coli and Staphylococcus aureus. The phytochemical analysis of the leaf extract revealed the presence of bioactive bases responsible for antibacterial property, such as Saponin, Alkanoid, Flavonoid, Tanin and Steroid. The methanolic extraction of the active ingredient of the leaves was carried out using the method as described by Fatope, (1993). The minimum inhibitory concentration (MIC)...
This seminar report provides an in-depth examination of the microorganisms causing soft rot of tomato. Tomato (Solanum lycopersicum) is a red edible fruit having many varieties which are widely grown, often in greenhouses in cooler climates and open fields. It is consumed in diverse ways, including raw, as an ingredient in many dishes and sauces, in drinks and as a vegetable for culinary purposes. Diseases are a major limiting factor for tomato production. Diseases can be classified into two ...
