Genetic characterization of angular leaf spot resistance in selected common bean landraces from Tanzania
Angular leaf spot disease (ALS) caused by Pseudocercospora griseola is one of the most important bean diseases in Tanzania. The bean landraces Beti-10, Nanka, Nanavala and Nkanamna used in this study have been identified as resistant to ALS but the nature of inheritance and mechanisms of resistance against ALS in those potential sources has not been elucidated. This information is crucial and a necessary first step for...

Laboratory study on influence of plant growth promoting rhizobacteria (PGPR) on growth response and tolerance of Zea mays to petroleum hydrocarbon
The influence of rhizobacteria on the growth and tolerance of Zea mays (maize) in a petroleum hydrocarbon (crude oil) impacted medium was investigated. This study evaluated the effect of inoculating maize seeds with plant growth promoting rhizobacterial strains in a crude oil impacted medium. The rhizobacterial strains used in this study were tested for plant growth promoting traits [indole-3-acetic acid production,...

Milk quality in high production systems during dry and rainy seasons according to normative instruction N° 62
This study aimed to evaluate the milk quality of crossbred cows from five production systems according to the quality parameters required by Normative Instruction No. 62 (NI 62). Five different production systems were used, with different environmental and sanitary conditions, and with animals from different breeds in two seasons: dry and rainy. Three individual milk samples were collected from animals in the five...

Bioguided investigation of the antimalarial activities of Trema orientalis (L.) Blume leaves
Malaria remains a major public health concern which affects millions of people, particularly in Sub-Saharan Africa. The need for the development of alternate treatment means has become critical because of the emergence of resistance to nearly all antimalarial drugs (Kim and Schneider, 2013). Trema orientalis (L.) Blume (Ulmaceae) is used locally for the treatment of malaria. This study was designed to determine the...

Antibacterial activity of secondary metabolites isolated from Alternaria alternata
The aims of this study were the analysis of the secondary metabolites and evaluation of the antibacterial and antifungal activity of Alternaria alternata. Twenty six bioactive compounds were identified in methanolic extract of Alternaria alternata. The identification of bioactive chemical compounds is based on the peak area, retention time molecular weight and molecular formula. GC-MS analysis of A. alternata revealed...

Drug resistant Salmonella in broiler chicken sold at local market in Bangladesh and its public health significance
Salmonella is a globally widespread food-borne pathogen having major impact on public health. Salmonellosis is an infection with bacteria called Salmonella. Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 h after infection. This study was designed to isolate and identify Salmonella spp. from cloacal swabs of apparently healthy broiler chickens in Bangladesh. Salmonella was...

Effect of reproductive status on body condition score, progesterone concentration and trace minerals in sheep and goats reared in South Sinai, Egypt
This study aimed at evaluating the effect of reproductive stage on nutritional status, and hormonal and trace mineral levels in sheep and goats reared in harsh arid conditions in South Sinai, Egypt. Egyptian local breeds of sheep (n=74) and goats (n=58) raised in South Sinai were examined by means of transabdominal ultrasonography to verify single vs. multiple feti pregnancy or non-pregnant status. Serum samples were...
