Comparative antimicrobial potentials of omidun obtained from yellow and white maize varieties on some diarrhoea causing microorganisms
This study determines the comparative antimicrobial potentials of omidun “supernatant solution of fermented maize mash” from yellow and white maize varieties on some diarrhoea causing microorganisms. The pH of the two omidun varieties were determined, their antimicrobial activities was also determined using agar well diffusion. Disc diffusion assay was also done using commercially produced antibiotics....

Bacteriological and physicochemical qualities of traditionally dry-salted Pebbly fish (Alestes baremoze) sold in different markets of West Nile Region, Uganda
The present study aimed at estimating the microbiological and chemical characteristics of traditionally dry-salted fish product, Alestes baremoze. A total of 40 random dry fish samples were collected from Arua, Nebbi, Packwach and Panyimur markets. Moisture content, pH, crude protein, crude fat and sodium chloride were analysed to determine chemical quality while Escherichia coli, fecal streptococci,...

In vitro antagonistic activity of native bacteria isolated from soils of the argentine Pampas against Fusarium tucumaniae and Fusarium virguliforme
The aim of the present study was to evaluate indigenous PGPR (Plant growth promoting rhizobacteria) previously isolated from Argentina's soybean fields for their in vitro antagonistic effects on the control of Fusarium tucumaniae and F. virguliforme, in two separated in vitro assays. In assay 1, the bacteria that showed the highest significant (P < 0.05) F. tucumaniae mycelial growth inhibition were strains...

In vitro antimicrobial activity of maggot excretions/secretions of Sarcophaga (Liopygia) argyrostoma (Robineau-Desvoidy)
The excessive usage of conventional antibiotics leads to the emergence of multidrug-resistant bacterial strains which threaten public health and stimulates searching for new sources of bio-therapeutic drugs. The aim of this study was to investigate the antimicrobial activity of maggot excretions/secretions from larvae of Sarcophaga argyrostoma, a common species of the family Sarcophagidae in Egypt. The...

Fungi extract in the inhibition of the egg hatching and larval development of the Haemonchus contortus
In vitro efficacy of aqueous and ethanolic extracts of Paecilomyces lilacinus and Trichoderma longibrachiatum was assessed in the egg hatching inhibition (EHI) and larval development inhibition (LDI) of Haemonchus contortus. For the EHI assessment, after 48 h of incubation with different concentrations of aqueous and ethanolic extracts, it was quantified blastomeres, embryonated eggs, and larvae of first stage. For the...

Microbial contamination of orthodontic appliances made of acrylic resin
Patients and professionals involved in dentistry are constantly exposed to potentially pathogenic microorganisms, which may be present in agents such as instruments and equipment, among others. The production of orthodontic appliances, as well as other dentistry work, is carried out in a dental laboratory where there is potential for cross-infection. Nevertheless, studies which evaluate the presence of bacterial...

Antibiofilm effect of Tucumã (Astrocaryum sp.) endosperm against Candida albicans
Candida albicans is one of the most relevant human opportunistic pathogens and highly competent to build biofilms on vital and non-vital surfaces. Facing the escalating resistance of microorganisms to current antimicrobials and fungicides, the Amazonian biodiversity may bring raw material to the development of new antimicrobial drugs. Astrocaryum sp. is a regional fruit, consumed in natura or as ice creams and other...
