Abstract: A recent discovery highlighted that mosquitoes infected with Microsporidia MB are unable to transmit the Plasmodium to humans. Microsporidia MB is a symbiont transmitted vertically and horizontally in the mosquito population, and these transmission routes are known to favor the persistence of the parasite in the mosquito population. Despite the dual transmission, data from field experiments reveal a low prevalence of MB-infected mosquitoes in nature. This study proposes a compartme...
Abstract: We report here the genome sequence of a Commensalibacter sp. strain (AMU001) isolated from honey bees (Apis mellifera) from Seychelles. By combining long- and short-read sequencing technologies, we produced the first complete reference genome assembly for the Commensalibacter genus. We anticipate that this will aid future comparative and functional genomic studies.
Abstract: Microorganisms in the intestinal tracts of termites play a crucial role in the nutritional physiology of termites. The bacterial diversity in the fungus-cultivating Macrotermes michaelseni was examined using both molecular and culture dependent methods. Total DNA was extracted from the gut of the termite and 16S rRNA genes were amplified using bacterial specific primers. Representatives from forty-one (41) RFLP patterns from a total of one hundred and two (102) clones were sequence...
Abstract: Pseudomonas aeruginosa is a leading cause of nosocomial infections worldwide. It can produce a range of debilitating infections, have a propensity for developing antimicrobial resistance, and present with a variety of potent virulence factors. This study investigated the sequence types (ST), phenotypic antimicrobial susceptibility profiles, and resistance and virulence genes among clinical isolates from urinary tract and skin and soft tissue infections. Fifty-six P. aeruginosa clin...
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 Ten packaged, freshly sliced watermelon were collected from different street vendors to determine their microbiological quality. Eight different microbial isolates were obtained from the sliced watermelon samples, namely Escherichia coli, Klebsiella aerogenes, Proteus mirabilis, Staphylococcus aureus, Lactobacillus spp., Saccharomyces cerevisiae, Rhizopus stolonifer and Mucor spp. The effects of high density polyethylene (HDP) and low density polyethylene (LDP) packaging bags on the ...
Abstract The research was carried out on the floral composition of Neni-Nimo watershed between November 2019 and July 2020. The research work aimed to find out the various plant species that inhabit the watershed, their abundance measures and importance values. In this study, the watershed was divided into three catchment areas, the upper, the middle and the lower catchment. Each of the catchment zones was divided into component parts, with an area of (50 m X 30 m) each. The experiment was la...
Introduction Swine flu is a human respiratory infection caused by an influenza strain that started in pigs. The World Health Organization uses the term "(H1N1) 2009 pandemic" when referring to the Swine flu event, and officially adopted the name "A(H1N1)pdm09" for the virus in 2010, after the conclusion of the pandemic. Swine flu was first recognized in the 1919 pandemic and still circulates as a seasonal flu virus. Swine flu is caused by the H1N1 virus strain, which started in pigs. The Apri...
Typhoid fever is a communicable disease transmitted by the bacteria Salmonella typhi, related to serotype paratyphi A, B and C. The disease is a significant health concern in most developing countries especially Cameroon. Objectives: The study aimed at assessing the risk factors associated to typhoid fever in children (0-18 years) attending the “Deo Gratias” hospital in Douala. Method: A hospital based cross sectional study from August to September 2018 was carried out in children aged 0-...
In most parts of Cameroon particularly the Menoua Division, common bean (Phaseolus vulgaris L.) is usually consumed immediately after harvest or after a few months of storage. Contamination of common bean by fungi usually occurs in the field and during storage. It is possible that the incidence of food contamination by fungi varies between field and storage. The study aimed at determining the incidence of common bean infection by fungi during harvest and during storage. Six common bean cultiv...
ABSTRACT The immune status of children under 15 years in the Southwestern region of Nigeria against measles virus was determined using the neutralization test with a view to assessing the herd immunity to the virus in these communities. A total of 256 serum samples collected from children were tested by the beta method of neutralization. Forty (15.6%) of these samples were found to be positive at a titre of 1:256, 35 (13.7%) at 1:128, 36(14.1%) at 1:64, 37(14.S0h) at 1:32. 38 (14.8%) at 1:16,...
