Potato cyst nematodes (PCN), Globodera rostochiensis and Globodera pallida are major limiting factors to potato cultivation globally. Effective use of nematode antagonistic bio-agents is a potentially important component of the eco-friendly agro-farming. Pseudomonas fluorescens and Purpureocillium lilacinum are known for their nematode antagonistic potential and plant growth promotion ability. The effect of seed treatment with liquid suspension of P. fluorescens at 1 l/ton seeds and soil drenching with suspension of P. lilacinum at 5 l/ha, singly and jointly, was studied to minimize the damage caused by PCNin potato plants under field conditions in two regions in India. Both applications showed significantly greater PCN suppression and better plant growth promotion in comparison to solo application. The both application showed the highest reduction of cyst population (75.7%) in soil, female population (79.9%) in root and egg numbers per soil of each location (84%). The potato plants from P. fluorescens-seed treatment and P. lilacinum-soil drenching both applied plots were 33.5% taller with 45.6% more number of tubers than untreated plants. The tuber yield was also significantly higher (35.9%) in both application than untreated control. There was no significant difference on the root colonization of P. fluorescens and P. lilacinum in solo and both treatments.

Backgrounds: This study aimed to describe the epidemiological and clinical characteristics of inactive HBV chronic carriers at the gastroenterology department of the university teaching hospital Yalgado Ouedraogo.
Materials & Methods: This descriptive cross-sectional study was conducted from January 1, 2007 to December 31, 2014 by employing a prospective data collection method. It was a census of all cases meeting the eligibility criteria. All patients with chronic viral hepatitis B (VHB) and ≥15 years of age and presenting the following signs were included in this study: positive result on hepatitis B surface antigen test for at least 6 months, normal levels of alanine amino-transferase for at least one year, positive anti-HBe antibodies, negative HBeAg, and viral DNA < 20,000 IU/mL.
Findings: The mean age of patients was 35 years, and the mean duration of HBsAg carriage was 6 years. The physical examination was normal in all participants. Ultrasound exam was normal in 150 (92.6%) participants and showed a fatty liver in 12 (7.4%) participants. Overall 4.4% of participants developed severe fibrosis, and no patient developed cirrhosis. The main indications for drug treatment included the existence of a family history of hepatocellular carcinoma (36.7%), the presence of active hepatitis (33.3%), and the progression of the fibrosis (30%).
Conclusion: This study confirms the importance of close follow up of HBV-infected patients to dramatically reduce the risk of developing complications such as cirrhosis or hepatocellular carcinoma.
