CHITIN AS A POSSIBLE ADJUVANT FOR RECOMBINANT HEPATITIS B VACCINE IN MICE

ABSTRACT Although adjuvants are a common component of many vaccines, there are few adjuvants licensed for use in humans due to concerns about their toxic effects. The currently available HBV vaccines contain hepatitis B virus surface antigen (HBsAg) as the immunodominant antigen and alum as an adjuvant. Alum, the most commonly used adjuvant in vaccines licensed for human use, predominantly activates Th2-type humoral immune responses, but is poorly effective in ...

GENETIC PROFILING OF ABC (CDR1) TRANSPORTER GENES OF AZOLE RESISTANT STRAINS OF CANDIDA SPECIES ISOLATED FROM WOMEN OF REPRODUCTIVE AGE

ABSTRACT Vulvovaginal candidiasis (VVC) caused by excessive growth of yeasts in the vaginal mucosa is estimated to be the second most common vaginal infection affecting women of reproductive age. The azole antifungal agents are the most frequent class of antifungals used to treat Candida infections, however; there is an extensive documentation of intrinsic and developed resistance to azole antifungals among several Candida species. Some transport proteins such as ATP- Binding ...

ISOLATION PARTIAL PURIFICATION AND STABILITY STUDIES OF MANGANESE PEROXIDASE FROM WHITE ROT BASODIOMYCETES, PLEUROTUS TUBER-REGIUM

ABSTRACT Manganese peroxidase (MnP) enzyme is the most common lignin-modifying peroxidase produced by almost all wood-colonizing basidiomycetes causing white-rot and various soil-colonizing litter- decomposing fungi. Multiple forms of this glycosylated haeme protein with molecular weight normally at 40 to 50 kDa are secreted by ligninolytic fungi into their micro-environment. In the present study, a ligninolytic fungus was able to produce manganese peroxidase. The organism was identified as Pleurotus tuber-regium. Parameter ...

COMPARATIVE STUDIES ON THE EFFECTS OF DIFFERENT MODIFICATIONS ON THE COLD WATER SOLUBILITY OF STARCH FROM SELECTED UNDERUTILIZED LEGUMES

ABSTRACT The industrial utilization of native starch is limited by its imperfect nature, hence the need for modifications.  The continued  use of conventional  crops such as cassava,  maize,  rice and potato as sources of starch for industrial uses adds to the demand pressure on these crops. On the other hand, the isolation of starch from underutilized legumes will not only reduce this pressure, but will also add value to boost ...

PREVALENCE OF ANTIBIOTIC RESISTANCE AND EXTENDED-SPECTRUM β-LACTAMASE (ESBLs) GENES IN ESCHERICHIA COLI ISOLATED FROM NON-DIARRHOEA STOOLS IN NSUKKA.

ABSTRACT 2   Antibiotic resistance has emerged as a major threat to global health. Extended spectrum β- lactamases (ESBLs) are enzymes that confer resistance to β-lactam antibiotics and acquisition of ESBL genes and integrons by Escherichia coli is increasingly recognized, being associated with resistance to multiple antibiotics. This study investigated the prevalence of multidrug resistance (MDR), ESBLs genes and integrons in E. coli isolated from non-diarrhoeal human stools. Stool samples ...

PH AND THERMAL STABILITIES OF PEROXIDASE ISOLATED FROM RIPENING TOMATO FRUITS (SONALUM LYCOPERSICON)

CHAPTER ONE INTRODUCTION The super-family of peroxidases from plants, fungi and bacteria are haem proteins that catalyse the oxidation of various electron donor substrates (phenols,  aromatic amines)  at  the expense of hydrogen peroxide (Welinder, 1992). Peroxidases contain iron (III)  protoporphyrin IX (ferriprotoprophyrinIX), as the prosthetic group. They have a molecular weight ranging from 30 to 150kD and may be divided into mammalian, microbial and plant peroxidases (Welinder, 1992). The haem ...
