Abstract

Salmonella typhi is an obligate pathogen that is usually found in clinical specimen from typhoid fever patients. The pathogenic mechanism of bacteria are not fully elucidated especially its potential activity of the outer membrane protein (OMP) as hemaglutinin and adhesion molecule. After identification, bacterial isolate of outer membrane protein fraction 12,5% SDS-PAGE were used to isolate OMP followed by hemaglutinin test and in vitro adhesion test. The study showed that the 55 kDa protein of S. typhi is a hemaglutinin protein that could agglutinate, Wistar mouse erythrocytes. The 55 kDa OMP is also an adhesion protein showed by its activity to adherence to Wistar mice’s enterocyt. The increased dose of 55 kDa OMP will decrease the amount of S. typhi bacteria adherenced to Wistar mice’s enterocyt. Outer membrane protein 55 kDa S. typhi as hemagglutinin and also adhesion protein.

Abstract

The aim of this study was to evaluate the effects of different frequency feeding and aging of leaves on increasing weight of silkworm instar IV-V and cocoon production. The research was conducted in Cultivation Center of Silkworm Candiroto, Temanggung. The research design was Factorial Design with three level of age from the leaves (the third – fourth leaves from tip of leaf; fifth-sixth leaves from tip of leaf; sevent-eight leaves from tip of a leaf, and three level of feeding frequency 3, 4, 5 times/day). The parameter observed were average daily gain (ADG), weight of cocoon, and weight of empty cocoon. The data gained were analyzed by analysis of variance and to find out the difference caused on the treatments, Duncan Multiple Range Test was used. It is concluded that the different frequency of feeding and age of leaves is significant (P < 0.05) in ADG of silkworm and weight of empty cocoon. The seventh- eight leaf from tip of a leaf, and frequency of feeding five times/day resulting ADG and empty cocoon of the best.

Abstract

Study on biology reproduction was expected to give basic information for management, such as for aquaculture, capture fisheries and conservation of P. polyuranodon in Musi river. Sampling were conducted on June 2006, August 2006, January 2007, and July 2007 in Musi river by using gillnet. Data analysis included length-weight relationship, sex ratio, condition factor, gonad maturity stage, Gonadosomatic Index (GSI), fecundity, and spawning type. Total number of collected P. polyuranodon was 51, consisted of 23 male and 28 female. Total length of fish was ranged in 85–511 mm. Length-weight relationship of male and female was W = 0.00002L2.8062 and W = 0.0002L2.8215 respectively. The result from t-test analysis showed that both of sexes have allometric negative growth. Sex ratio thoroughly was balance (1:1). Mean of factor condition relatively increased by the increasing of gonad maturity stage. At that time P. polyuranodon was entering spawning time. June and August was predicted as the spawning time of this species. Gonadosomatic index of female was much higher than the male. Fecundity of female was ranged between 616 and 7,059. Based on distribution of egg diameter, this species was total spawner.

Abstract

An experiment to investigate the affectivity five isolat of Arbuscular Mycorrhizal Fungi (AMF) on the growth of banana (Musa sp.) obtained from tissue culture had been conducted at the Plant Biotechnology laboratory, Glasshouse, and Experimental farm of the Faculty of Agriculture Jambi University. The results showed that there were five mycorrhizal isolates that can be tested for their affectivity on banana seedlings. The growth responses of the seedlings inoculated with AMF was higher than those non-inoculated seedlings due to higher rate of nutrient uptake. Each kind of AMF possesses different level of effectiveness on banana seedling. The application of single isolate Glomus sp-1 at acclimatization time resulted that highest effectiveness.
