Fusarium spp. and fumonisin in feed for equine and its importance for occurrence of leukoencephalomalacia
In the animal feed industry, an ever growing increase in quality has been observed, but the main feature of a food is related to its security because the contamination poses a risk to animal health. The problems caused by fungal colonization is the significant loss of food quality, because even those who do not produce mycotoxins cause losses in the nutritional quality. Researches show that the most important Fumonisins...

Microbial species of safety concern in milk from informal processors in Harare, Zimbabwe
In this study, the bacteriological quality and the presence of Staphylococcus aureus, Escherichia coli O157:H7, Bacillus cereus, Salmonella species, and Pseudomonas species were studied in raw milk, cultured milk, milk handlers and packaging containers. A total of 36 samples were collected over 3 months from three different farmers. Samples were analyzed for means of counts per milliliter of milk for total bacterial...

Evaluation of a non-submerged cultivation assay combined to ESEM imaging for analysis of biofilms formed by dairy-associated sporeforming bacteria
In the dairy industry, the biofilms formed by spore forming bacteria are not well characterized. Microscopic methods are crucial for the study of biofilm structural and architectural features. Here, a simple surface-associated non-submerged model combined to environmental scanning electron microscope (ESEM) imaging was used for the study of Bacillus cereus and Geobacillus spp. dairy biofilms. To evaluate the utility of...

Cytokinins production by fluorescent Pseudomonas isolated from rhizospheric soils of Malus and Pyrus
Information on microbial production of cytokinins and their effect on plant growth are limited. Therefore, the objective of the present study was to investigate cytokinins production by Pseudomonas sp., a major component of rhizobacteria with multiform and diverse activities, which enhance plant growth by synthesizing various secondary metabolites. In the present investigations, thirty Pseudomonas isolates were isolated...

Antibacterial susceptibility spectrum of some gram negative bacteria from suspected Otitis media patients
Otitis media (OM) is a multifactorial disease characterized by high rate of recurrence in young children and considered to cause hearing impairment in children. This study was undertaken to evaluate the antibacterial sensitivity of Gram-negative bacteria of OM to some antibiotics. A total of Fifty four (54) samples were obtained from patients with suspected cases of otitis media coming into the National Ear Care Centre...

Nosocomial infection caused by multidrug resistant Enterobacteriaceae and their spread in inanimate surfaces in East-Algerian hospitals
The inanimate hospital environment may serve as a reservoir for resistant bacteria that pose nosocomial infection risks often originating from cross contamination and the most common means of pathogens transference occurs between hands of health professionals, hospital equipment and patients. The aim of this study was to investigate various nosocomial infections with multidrug resistant Enterobacteriaceae (MDR-E) and...

Cloning and characterization of an endo-β-1,4-xylanase gene from Colletotrichum lindemuthianum and phylogenetic analysis of similar genes from phytopathogenic fungus
Colletotrichum lindemuthianum is the etiological agent of anthracnose, one of the main diseases of bean (Phaseolus vulgaris). In this study, the complete cDNAs of two endo-β-1,4-xylanase genes (xyl1) from non-pathogenic (0) and pathogenic (1472) races of C. lindemuthianum were isolated and characterized. To get an insight into the role of endo-β-1,4-xylanases in their different lifestyles, xyl1 gene expression...

Effects of temperature and incubation time on growth and ochratoxin A biosynthesis by Aspergillus carbonarius and Aspergillus ochraceus in grain-based media
Ochratoxin A (OTA) has been frequently found as a food contaminant, and it is considered one of the mycotoxins most harmful to human health. In this context, this study was performed aiming to evaluate mycelial growth and ochratoxin A production from three isolates of Aspergillus carbonarius and Aspergillus ochraceus. The isolates were inoculated on culture media coffee, wheat and maize as well as YES medium and...

Recovery and prevalence of antibiotic-resistant Salmonella from fresh goat meat in Arusha, Tanzania
Meat products are clearly associated with foodborne pathogens including, antibiotic-resistant strains. Population growth and growing consumer demand facilitate the transmission of foodborne pathogens, particularly in developing countries. To determine the prevalence of antibiotic-resistant Salmonella in goat meat, a study was done in Tanzania (June to July, 2015). Overall 120 goat meat samples were collected from...
