Abstract

Toxoplasmosis is an infectious disease caused by Toxoplasma gondii. This disease could severelyaffect humans and animals. Up to now there has been no simple treatment to fight toxoplasmosis. Aprospective alternative treatment to overcome this problem is by increasing immunity of the body using animmunostimulant such as Spirulina platensis. The aims of this research were to observe the potency of S.platensis as an immunostimulant and to find the most potential fraction of S. Platensis that can increasethe responses of IgG and IgM antibodies againts toxoplasma. The responses of these antibodies weremeasured using ELISA method. The isolation of compounds from S. platensis using Preparative ThinLayer Chromatography (PTLC) found three fractions which were a top fraction (I), a middle fraction (II),and a lower fraction (III). Forty-eight mice used in this research were divided into four different groupswith 12 mice in each group and treated differently. The top, middle, and lower fractions of S. platensis wereadministered orally to three groups of mice respectively at dose of 3mg/ml for each mouse while the micein the fourth group were kept as untreated controls. The treatment was conducted for 14 days consecutivelyand on the next day, all mice, including the controls, were challenged with tachizoit. The effect of S.platensisfractions on the responses of IgG and IgM antibodies were then measured at various time intervals, i.e. day0 (before infection) and day 1, 2, and 3 after infection. The results showed that IgG response increased inthe day 0 (2.504 OD) and the day 3 after infection (2.608 OD) while IgM response increased in day 1 afterinfection (2.898 OD). In conclusion, S. platensis was an immunostimulant and the middle fraction (II) of S.Platensis was the most potential fraction to increase immunity againts toxoplasma .

Abstract

In conservation, identification of tarsier species based on morphological and molecular characters isrequired. However, to date the identification of animals is simply based on their morphological characterand vocalizations, while in fact it is difficult to identify each species of Tarsius sp morphologicaly.  Thepurpose of this study is to obtain genetic markers that can be used to identify Tarsius sp on ND6 mitochondrialgenes and reveal affiliations and phylogenetic relationships Tarsius sp. with other members of primates.Samples were obtained from several original habitats of Tarsius sp. Three samples were taken from NorthSulawesi, one sample was collected from Central Sulawesi, three samples from Kalimantan  and threesamples from South Sumatra. The isolated DNA is then used as a template for amplification of DNAfragments by PCR. Amplicon (PCR product) obtained 566 bp and 629 bp. Nucleotide sequencing resultsshows 513 nucleotides, the smallest genetic distances of 0%, the highest of 30.2% and average of 16.3%.Nucleotide and amino acid sequences of ND6 can be used as genetic markers to differenciate T. spectrum,T. dianae and  T. bancanus but they fail to function as genetic markers to distinguish  T. bancanus ofKalimantan and Sumatra origin.

Abstract

Rapid and accurate detection performs an important role in the control of raising MDR-TB. Currently, studies on biomarkers as targets for TB diagnostic tests using immune response products to indicate the presence, mycobacterial load, early markers, and activity, diff erentiation, and progression markers of TB infection are rapidly available. This systematic review aims to summarize the last fi ve years of potential biomarkers studies from the immune response for MDR-TB rapid diagnostic development. The authors performed a literature search on four databases as ProQuest, EBSCO Academic Search, Universitas Gadjah Mada Online Library Journal Database, and Google Scholar, retrieved from January 2016 to December 2021. In total, 18,288 articles were identifi ed and three tudies met the inclusion criteria. Several promising biomarkers were found for MDR-TB diagnosis purposes, such as sCD14, PGLYRP2, FGA, Indoleamine 2, 3- dioxygenase (IDO), and Complement Receptor 2 (CR2). A combination of sCD14, PGLYRP2, and FGA were bringing a diagnostic design with a higher sensitivity (94.7%) and specifi city (80%) than the design of a single protein. Higher IDO activity towards the MDR-TB group than in the DS-TB group with a sensitivity of 87.50 %, specifi city of 72.22 %. CR2 was the main focus due to its association with IL-6. After induction of CR2 peptide in a dose-dependent manner, the expression level of IL-6 was decreased signifi cantly. It might because of CR2 peptide regulating the macrophages proinfl ammatory cytokines secretion to decrease the local infl ammation of the immune response. These biomarkers are strong candidates for MDR-TB diagnosis due to their important role as the pathogenesis marker of MDR-TB. There is a need of further research to investigate those immune response products and their role to eliminate infection of Mycobacterium tuberculosis directly.
