POPULATION DENSITY OF LESSER DATE MOTH ON MOST PROMINENT DATE PALM CULTIVARS AT KHAIRPUR MIRS

Pakistan is a more peculiar and hearty zone for almost all types of date palm cultivars but only District Khairpur Mirs of Sindh is regarded as “Khajeen jo dees”. The field survey-based research study was conducted at Taluka Kingri, District Khairpur during, 2017-18. The present study was sought on viz., Aseel, Nar-aseel, Fasly, Karbalian, Otakin, Daki-wari, Asul-kurh, Kashoo-wari, Asul-khurmo, Dedhi-wari, Lessoro, Begun-wari, Gajar-wari, Noori-wari and Nakul-kurh date palm varieties. All the novel already cultivated varieties were observed through random selection against the population density of Batrachedra amydraula. The pest data was taken every week from April, May and June months in both years of the study period. The pest data was gathered from 15 acres of cultivated Phoenix dactylifera orchards and prohibited to any insecticides. The maximum suspected pest infestation was found on Fasli cultivar whereas; the minimum infestation was recorded on Aseel. This commercial high-priced variety is found with high tolerance capability against salinity, drought, and upper range temperature conditions and hence recommended for cultivation. In the present study, it was frequently observed the appearance of the Batrachedra amydraula on all novel cultivars. The “Khajoor” is the cash crop and the main economic source of livelihood of this region but for a few decades, LDM has leads productivity reduction in terms of quantity and quality. The food security and socio-economic status of date palms are poorly documented in Pakistan. In this context for date palm crop security, more work should be carried on against population reduction of LDM.

IMPROVING MCCP VACCINE IN SHEEP: NOVEL STRATEGIES FOR DEVELOPMENT, EFFICACY AND CROSS-PROTECTION

Vaccination serves as a straightforward and efficient method for preventing numerous infectious diseases in animals. One such disease is contagious caprine pleuropneumonia (CCPP), a severe lung ailment affecting small ruminants. This research aimed to create a vaccine utilizing Mycoplasma capricolum subsp. capripneumoniae (Mccp) isolated from KPK, Pakistan. The local Mccp strain was rendered inactive alongside saponin, a substance, to produce the vaccine. The viable count of Mycoplasma mycoides subsp. capripneumoniae (Mccp) was determined to be 1x108 CFU/mL from the stock culture, with an estimated protein content of 0.2g/ml. The developed vaccine underwent testing and comparison with a standard CCPP vaccine in sheep to assess safety and efficacy. Twelve experimental sheep were divided into three groups: A, B, and C. Group A received the new vaccine, group B received the standard vaccine, and group C acted as the control. Groups A and B were further split into two subsets: one remained healthy while the other fell ill. The sheep were closely monitored for any changes over a 75-day post-vaccination period. Blood samples were analyzed for antibodies, showing average antibody GMT titers of 24.3, 84.4, and 128 on days 21, 28, and 35 post-immunization. By day 35, sheep vaccinated with the new vaccine displayed the highest antibody levels. The quadratic relationship (R2) indicated that both saponized and lyophilized vaccines were influenced by the number of days by 57.4% and 55%, respectively. The new vaccine demonstrated superior efficacy in sheep compared to the standard vaccine, with saponin playing a role in its effectiveness. The study successfully deactivated Mycoplasma mycoides subsp. capripneumoniae cells with autoclaved saponin, ensuring a sterile vaccine. In vivo testing in rabbits confirmed the vaccine's safety, while serum analysis in sheep revealed protective antibody responses, with the saponized vaccine eliciting higher titers than the lyophilized version. These findings suggest the potential efficacy of the saponized vaccine against Mccp infection

PURIFICATION AND CHARACTERIZATION OF AMYLASE PRODUCED FROM PROBIOTIC LACTOBACILLUS PLANTARUM CS FOR INDUSTRIAL APPLICATIONS

Previous studies have demonstrated that probiotic Lactobacillus plantarum CS was able to generate an appreciable amount of extracellular amylase, hence the need to purify and characterize it. The aim of the study was to purify and characterize crude amylase from probiotic Lactobacillus plantarum CS for its industrial applications Three purification steps including ammonium sulphate precipitation, ion exchange chromatography on carboxymethyl sephadex and gel filtration on Sephadex G-75 were utilized. The homogeneity of the purified enzyme was confirmed using sodium deodocyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). The purified amylase was characterized on different parameters including substrates hydrolyses, pH and temperature activity and stability profiles. The general purification elution profile revealed two different peaks of amylase activities with outstanding one having a molecular weight of 59.7kDa. Its purification fold was 4.0 with specific activity of 16.44U/mg protein and enzyme yield of 3%. Temperature optimal activity and stability was at 400C and 7.5 for pH activity and stability. Mangenese (Mn2+) (135.17%), tween 80 (128.30%) and some food condiments garlic, thyme, ginger, and tumeric) significantly (p> 0.05) enhanced amylase activity (≥262.40%). However, selenium (Se4+) and hydrogen peroxide (H2O2) were observed to have greatest inhibiting effect (≥30.9%) on the enzyme. Substrate hydrolysis profiles showed that the amylase hydrolyzed all the test starchy substrates with the highest hydrolytic potential on indigenous sweet potato starch (Km value/ Vmax of 1.33mg/ml/ 7.89ml). The rate of hydrolysis of other test substrates had yam> rice>cassava>corn with km values ≤ 4.0mg/ml and Vmax ≤ 25ml. The obtained results gave an insight that amylase produced from Lactobacillus plantarum CS met with the possessed properties suitable for any industrial application especially in food
