Ralstonia solanacearum is a major constraint in tomato production. The aim of this work was to identify the different biovars and races of R. solanacearum which infect tomato plants in Cameroon and determine the most virulent in a gnotobiotic environment. Thirty (30) samples were collected in the field of 03 different agro-ecological zones considered as major tomato production area in Cameroon. The bacteria were isolated on modified Kelman solid medium, and identified based on morphological and biochemical characterization. The pathogenicity test was performed in a gnotobiotic environment by r ..read more

Four different evaluation trials were conducted in the field between 2017 and 2020, with varied numbers of genotypes, to evaluate the performance of sunflower genotypes for agromorphological features and resistance to Sunflower Downy Mildew (SDM) at Latur, Maharashtra, India. A validation experiment was carried out in 2021–2022, using artificial screening in National Diseased Plot Screening Facility at Latur, to screen a small number of accessions that had previously shown resistance to SDM during 2017-2020. The released variety "Morden," also susceptible check showed at least 60% of the SDM i ..read more

Aim: The use of Moringa oleifera leaves has gained worldwide acceptance in use by animals and humans. The study aimed to determine the effects of ethanolic leaf extract of young and old Moringa oleifera on haematological, renal, and liver indices in Wistar rats. Design: A completely randomized design was used for the study. Place and duration of study: The study was carried out in the Animal Science Department of Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development and lasted for six weeks. Materials and methods: A total of twenty male Wistar rats of age eight wee ..read more

A case of dystocia due to post-cervical right side uterine torsion with the history of colic and straining since (days) in a pluriparous Mehsana buffalo was presented at the clinics of Veterinary Gynaecology and Obstetrics of Veterinary College, Sardarkrushinagar, Dantiwada, Gujarat, India. Maternal dystocia due to of uterine torsion was diagnosed by history, a clinical sign, per rectal and per vaginal examinations. At first we used modified Schaffer’s method for management of uterine torsion in buffalo. After the three rolls torsion was detorted successfully, but due to insufficient dilated c ..read more

To assess and compare different hormonal protocols' treatment efficacy in anoestrus buffalo heifers in a semi-arid region. Forty buffalo heifers with a history of anoestrus were chosen randomly from the semi-arid region of Banaskanth and divided into four equal groups.Group-I: Heatsynch protocol (n = 10), Group-II Ovsynch protocol (n = 10), Group-III Doublesynch protocol (n = 10) and Group-IV Control (n = 10) are followed by artificial insemination at a predetermined period in treated buffalo heifers and insemination during spontaneous estrus in group-IV buffalo heifers. In Groups I, II, and I ..read more

Fetal mummification is uncommon in small ruminants like goat and sheep. The twin mummification of fetuses confirmed by history, a clinical sign, ultrasonographical and per-vaginal examination in five year old Surti doe of fourth parity. The case was successfully managed therapeutically using intravenous administration of 3.0 ml Dexamethasone®, 20IU- Oxytocin®, 500ml-Normal saline and 30ml-Calcium magnesium borogluconate, whereas 5ml-Valethamate bromide (Epidosin®) was given intramuscularly. The goat resumed to normal appetite and appearing active and alert within a week post treatment ..read more

Canine pyometra is a common reproductive disorder of intact diestrual bitches. The disease is associated with inflammation and infection of the uterus leading to generalized illness. The varied reactions of the host to infection, inflammation, or trauma are collectively known as the acute-phase response (APR) and encompass a wide range of pathophysiological responses. One of these systemic responses to disease is an increase in the production by the liver of a number of serum proteins, which are known collectively as the acute-phase proteins (APP). The most important APPs in dogs are C-reactiv ..read more

Rice is the staple food for billions of people and a source of income for hundreds of millions. This food security crop production needs to be improved to face the projected demands of the exponentially augmenting world’s population and overcome biotic and abiotic stress in the fields. Optimized in vitro culture protocols are a prerequisite to genetic engineering which appears to be the best potential way to improve the rice plant. In this study, ‘Nerica 3’ and ‘Nerica L36’ seeds were in vitro culture tested into 4 media (m1-4), in dark and photoperiod environments. The percentage of callus in ..read more

Nowadays, molecular characterization is essential for studying the varietal diversity of species. In addition, SSR molecular markers are widely used to identify and distinguish the genetic relationship of mango cultivars. The study aim is to determine the variability structuring level of 18 mango cultivars in Burkina Faso. Thus, genomic DNA was extracted in 2022 from young leaves at the molecular biology unit of the Biosciences laboratory at Joseph KI-ZERBO University (Burkina Faso). Analysis of the results showed a polymorphic percentage average of 21.49% per marker. Genetic distance showed t ..read more

Integrated Nutrient Management (INM) is a holistic approach that aims to optimize nutrient use efficiency in cereal crop production by combining various sources of nutrients, including organic and inorganic fertilizers. The integration of organic materials, such as crop residues and manures, with chemical fertilizers is emphasized to enhance soil fertility, improve nutrient availability, and promote sustainable agricultural practices. The synergistic effects of combining different nutrient sources contribute to balanced nutrition, reduced environmental impact, and increased resilience to chang ..read more
