Abstract:Foot rot of rice caused by Fusarium moniliforme (Fusarium verticillioides) has become a major problem on certain cultivars of rice under Punjab conditions. The pathogen produces different types of symptoms (elongation, stunting or both and death of plants) in nursery as well as in field. The influence of the cultural media on morphological, cultural characteristics and growth rate of F. moniliforme on four different media: Potato dextrose agar (PDA), Soil Extract Agar (SEA), Spezieller Nahrstoffarmer (SNA) and Water Agar (WA) were studied and macro-conidial features were observed on carnation leaf Agar (CLA) medium. The pathogen was isolated from the foot rot infected Basmati plants, collected from different agro-ecological zones of Punjab. The colony color in PDA and SEA was varied between whitish to pinkish whereas in SNA and WA media it was observed to be white. The maximum colony diameter of Fusarium moniliforme was observed on PDA with 82.33 mm diameter and growth rate of 25.72 mm/ 48hrs, followed by SEA with colony diameter of 79.67 mm and growth rate of 19.65 mm/48hrs. Poor growth rate was observed on SNA with 16.55mm/ 48hrs growth rate and 47.98mm colony diameter. Lowest was observed on Water Agar (WA) with 35 mm colony diameter and 6.5mm/ 48hrs growth rate. Mycelial growth was dense and fluffy on both PDA and SEA. Moderate and sparse to thin growth on SNA medium was observed. No chlamydospores were observed on all the media under study. Sporulation was highest in SNA (6 x105 spores/ ml), followed by SEA (5.7 x105 spores/ ml) and PDA (4 x105 spores/ ml). But the culture show poor sporulation in WA.

Abstract: Brucellosis is a highly contagious and important zoonotic disease worldwide and is endemic in India. Antibiotics are currently used in treatment of Brucellosis. However, little information is available on the antibiotic sensitivity of field isolates of Brucella in different parts of India. We analyzed clinical samples (foetal stomach contents, foetal membranes, uterine fluid, vaginal mucous and milk) from cattle and buffaloes from Ludhiana for Brucella abortus organisms. Out of the total 104 samples analyzed, 12 were positive for Brucella abortus by isolation. The isolates were confirmed to be Brucella organisms by PCR. Morphological characterstics like smooth, glistening, translucent and pinpoint colonies appearing after 3-5 days of incubation in microaerophilic environment were indicative of Brucella. The organisms were found to be positive for catalase, oxidase and urease. H2S was produced by 7 isolates. All the 12 isolates were positive for nitrate reduction and were negative for indole test. All the 12 isolates of Brucella abortus were found to be positive by PCR using Brucella specific primers B4/B5 and F4/R2 which revealed the desired amplicons of 223 bp and 905 bp, respectively. Isolated organisms were sensitive to chloramphenicol, oxytetracyclin, ampicillin, streptomycin, gatifloxacin and ceftaxime but resistant to penicillin, cotrimazole, cephalothin and erythromycin.

Keywords: Brucella abortus, isolation, antibiotic resistant, Brucellosis.
