Abstract

The purpose of this study was to analyze the phylogenetic relationship of Gram negative bacteria (3strains of Salmonella typhi, 1 strain of Escherichia coli, 1 strain of Serratia marcescens, and 3 strains of Enterobactercloacae) of Enterobacteriaceae family in positive Widal blood cultures based on 16S rRNA gene sequences. Theresults respectively showed that each two 16S rRNA gene clones of Serratia marcescens KD 08.4 had a closerelationship with 16S rRNA gene of Serrratia marcescens ATCC 13880 (similarity: 99.53-99.8%), Eschericia coliBA 30.1 with Eschericia coli ATCC 11775T (similarity: 99.38-99.67%), Salmonella typhi BA 07.4, Salmonella typhiKD 30.4, and Salmonella typhi SA 02.2 with Salmonella typhi ATCC 19430T (similarity: 99.4-100%) as well as theisolates of Enterobacter cloacae SA 02.1, Enterobacter cloacae BA 45.4.1, one 16S rRNA gene clone of Enterobactercloacae TG 03.5 with Enterobacter cloacae ATCC 23373 (similarity: 99.0-99.87%).

Abstract

            Toxoplasmosis is a disease caused by protozoan parasite Toxoplasma gondii. The infection is commonly asymptomatic. The availability of confirmative and accurate detection system is really needed. This research was aimed to develop a molecular diagnosis based on the conserved and high copy number repeat region of Toxoplasma gondii with hibridization method. Nucleic acid was isolated from tachyzoites. The repeat region of T. gondii was amplified using PuRe Taq Ready To Go-PCR Beads (Amersham Bioscience),  forward primer 5’- GAC TCG GGC CCA GCT GCG  -3’ and reverse primer 5’- CCT CTC CTA CCC CTC CTC -3’. The amplicon was sequenced using ABI Prism 3100-Avant Genetic Analyzer (PT. Charoen Pokphand, Jakarta). Probe was labeled using digoxigenin-11-dUTP. Application of probe to detect it’s complementary nucloeic acid was done by hibridization method. The research concluded that probe toxo-103 bp was highly homolog with several strain of T. gondii and it has no homology either with host’s genome or other parasites which have close genetic relationship with T. gondii.   Hybridization analysis showed that probe could detect the complementary nucleic acid up to 10 ng/ul concentration.

Abstract

Gene encoding GRA1 protein is potent DNA-vaccine candidate against toxoplasmosis. The aim of the researchwas to clone the gene encoding GRA1 protein of tachyzoite Toxoplasma gondii local isolate by DNA recombinanttechnology. Tachyzoite was grown in Balb/c mice in vivo. Messenger RNA was isolated from total RNA and itwas used to synthesis cDNA. Complementary DNA encoding GRA1 protein of tachyzoite Toxoplasma gondii localisolate was amplified and cloned in a prokaryote cloning vector. The recombinant GRA1-encoding gene was thendigesting using EcoRI restriction endonuclease and sequencing. The result showed that the recombinant GRA1-encoding gene consisted of DNA sequences encoding all signal peptide and mature peptide of GRA1 protein.Alignment of recombinant GRA1 sequence to gene encoding GRA1 protein of Toxoplasma gondii RH isolate showed100% homologous.Keywords: GRA1 protein, Toxoplasma gondii, tachyzoite, cloning, cDNA

Abstract

The purpose of this study was to determine the chemosystematic of 14 strains of bacteria in blood cultures from Semarang using 1 reference strain S. typhi NCTC 786, based on the total protein profi les with the similarity relationship analysis based on Simple Matching Coeffi cient (SSM) analysis and algorithm methodof unweighted pair group with averages (UPGMA) presented in a dendrogram. The results showed that thechemosystematic based on the total protein profi les using SDS-PAGE method can classify the member ofbacterial strains of each species. The Clusters respectively consist of 4 strains of S. typhi (similarity: 89.7%),2 strains of Ser. marcescens (similarity: 89.7%), two strains of E. coli, and one strain of Salmonella ssp, S. typhi NCTC 786 (similarity: 100%). Those three incorporated clusters had the similarity value of 75.3%. Those four strains of Ent. cloacae composed in one cluster (similarity: 100%) are incorporated in a cluster consisting of one strain of Kleb. pneumoniae (similarity: 92.9%). Both clusters were incorporated in a cluster consisting of S. typhi NCTC 786 (similarity: 67.9%).Key words: Enterobacteriaceae, chemosystematic, blood cultures, protein profile

Abstract

Rhoptry protein belongs to an excretory and secretory antigens (ESAs) that play an important role during activepenetration of parasite into the cell target. This protein an able Toxoplasma gondii to actively penetrate targetedcell, meanwhile ESAs protein stimulates intracellular vacuole modification. It is, therefore, after the parasitesuccessfully enter the cell target then Granule (GRA) proteins are responsible for the formation of parasitophorusvacuole, which is protect the fusion with other intracellular compartments such as lysosomal vacuole. Consequently,this parasite is being able to survive and multiply at the cell target. The current study was aimed to clone andsequens cDNA encoding for ROP-2 of local isolated T. gondii tachizoite through DNA recombinant technique.Total ribonucleic acid (RNA) was isolated from tachyzoites of local isolated T. gondii that were grown up in Balb/c mice. Messenger RNA was isolated from total RNA using PolyAtract mRNA Isolation System. Messenger RNA wasused as a template for synthesis cDNA using Riboclone cDNA Synthesis System AMV-RT. EcoRI adaptor fromRiboclone EcoRI Adaptor Ligation System was added to Complementary DNA and than ligated to pUC19. Recombinantplasmid was transformed into E. coli (XL1-Blue). The transformed E. coli XL-1 Blue were plated on LB agarcontaining X-Gal, IPTG and ampicillin. Recombinant clones (white colony) were picked up and grown up in theLB medium at 37oC overnight. Expression of recombinant protein was analysed by immunoblotting in order toidentify cDNA recombinant wich is express ESA of T. gondii local isolate. Recombinant plasmid were isolatedusing alkalilysis method and were elektroforated in 1% agarose gel. The isolated DNA recombinant plasmid wascut using Eco RI and then sequenced through Big Dye Terminator Mix AB1 377A Sequencer using M13 Forward andM13 Reverse primers. The conclusion of this results showed that the recombinant clone was coding for excretoryand secretory protein which has molecular weight of 54 kDa. The DNA alignments of sequence from the clonedgene showed 97% homology with gene encoding for ROP-2 of T. gondii RH isolate.Keywords: Toxoplasma gondii, tachizoite, ESA, complementary DNA, ROP2

Abstract

Backgroud. Mass drug administration (MDA) has been one of the strategies for lymphatic filariasis elimination. Since the start of implementation in 2011 in Pekalongan, no study on MDA acceptability has yet been done. The objectives of the study were to determine the microfilaria rate (mf rate) and the risk factors of drug compliance in the MDA program. MethodsA longitudinal study was conducted at Pabean region, Pekalongan City. There were 90 household heads as subjects, who were selected by proportional cluster random sampling. Microfilaria rate (mf rate) was determined by finger blood examination. Drug compliance was measured using questionnaires and observation sheets. Drug compliance observers, filariasis counseling participation, and presence of filariasis patients were factors influencing drug compliance. ResultsMf rate in 2015 was 1.35% and drug compliance rate was 86.80%. Reasons for failing to take drugs were fear of side effects (50%), refusals (25%), laziness (16.7%), and perceiving the drug to be useless (8.3%). The chi-square test shows a significant difference between the presence of drug compliance observer and compliance (p=0.006). Filariasis counseling participation and presence of filariasis patients did not show a significant difference with drug compliance (p= 0.986).ConclusionsFamilies as the source of observers was associated with increased filariasis drug compliance. It is therefore essential to address the issues linked to low compliance to make the program more efficient and achieve the goal of filariasis elimination.
