Abstract

Performance of ELISA Toxoplasmosis Diagnostic Kits on Sheep and Human Sera Toxoplasma seropositivity in Indonesia have a high prevalence, both in human and animals. Unfortunately, the availability of diagnostic tools to support dynamic surveillance are limited. Recently, the diagnostic tools for toxoplasmosis, namely ELISA BM were developed. The technology was based on ELISA technique using soluble tachyzoite antigen from tachyzoites of Toxoplasma gondii. Kit performance is one of the important issue for acceptance of diagnostic tools prior to wide application. The purpose of the studies was to asses the quality of diagnostic toolsperformances. The assesment comprises of four stages. First stage was to evaluate the performance of ELISA BM compared to Latex Agglutination Test (LAT) on sheep sera. Secondly, to evaluate the performance of ELISA BM to descriminate true seropositive andseronegative toxoplasmosis on human sera. The last stage were comparing ELISA BM, ELISA TL (commercial kit) and LAT on predetermined and unknown human sera. The results showthat the accuracy of ELISA BM is slightly better than ELISA TL. Agreement of ELISA BM with LAT was better againts ELISA TL with LAT. However, all performance as determined using Cohen’s ? and Gwet’s AC1 of ELISA BM, ELISA TL and LAT were good up to very good agreement.Keywords: Toxoplasmosis, ELISA, Latex Agglutination, inter reliability agreement.

Abstract

ABSTRACTInfectious Bronchitis Virus (IBV) is an acute viral and highly infectious disease which attacks the respiratory system of chicken. The impact of economic losses is very large since it decreases the egg production and itcauses the abnormal of egg shapes, decreased of body weight and death. In Indonesia, the IBV disease is still a serious problem in poultry regarding to many variants which arise from mutations of the IB virus. The decreasing possibility of the vaccination effectiveness due to incompatibility of strains used towards the virus circulated in the field. The variants of IB virus have not been well-documented in Indonesia since the lack of characterization of this virus. In this study, we characterize the IB virus isolates obtained from our local outbreaks in the field in order to determine the variant of IB virus in Indonesia and provide recommendations for the improvements of IB vaccine seed viruses which is adapted to IB virus circulating in the field. The IB virus characterized in this study shows close genetic relationship with the IB virus from Taiwan and China. However, it did not correlate with the local IB virus that has been found previously.Keywords: Identification, Character, IBV, Indonesia

Abstract

"Cibinong Science Center LIPI or CSC’s LIPI as an artificial habitat to the bird species conservation, especiallywith their ecological parks. This research was to study the distribution patterns and dynamics of birdcommunities in the CSC’s LIPI areas during 2005 to 2009 and on 2014. Transect Line’s method was used inthis study. The results were 39 species of birds to live in the eight sites observation on 0.27 km2 areas.However, there are no significant effects, especially relationships between Margalef’s index value to area,cotton area closest distance to the river and their habitat situation. According to “multiple linear regression”analysis show that ?= 3.626-0.69 area -1.31 cotton area closest distance to the river + 0.94 habitat situation,with determinant coefficient value (R2) = 0.161. The densities of nine species were found high. Those specieswere Lonchura punctulata (D=49.37 individuals/ha), Zosterops palpebrosus (D=22.2 individuals/ha),Collocalia linchi (D=15.00 individuals/ha), Orthotomus sutorius (D=12.70 individuals/ha), Lonchura maja(D=12.48 individuals/ha), Passer montanus (D=12.19 individuals/ha), Pycnonotus aurigaster (D=7.37individuals/ha), Dicaeum trochileum (D=6.07 individuals/ha) and Streptopelia chinensis (D=5.85 individuals/ha). The diversity indices value (H’) 1.52 to 2.51 and the evenness indices value (E) 0.52 to 0.86. Thesimilarities indices value (SI) of birds in the CSC’s LIPI will be compare to another places, i.e. the IPBcampus at Darmaga, Bogor or Yogyakarta State University’s campus in Yogyakarta showed no different,relatively. The IS value were 58.82 to 61.54%. Birds in the CSC parks were high dominant to occure in thelower strata (27.78–43.18%) and upper strata (50.43-70.83%), while in the middle strata (1.39-9.15%) tend tobe slightly. Most activities were carried by birds , especially foraging and calls. Although, the birds in the CSCparks also breeding, take a rest etc . The CSC’s LIPI parks at Cibinong could be used as a reference to thebird’s artificial habitat model to others areas. That’s an important if the areas are industries complex or theCenter office of some government buildings. But, the composition and structure of the vegetation will bedeveloped in there should be to produce some natural food resources and safety well for breeding of birds.Keywords: bird species, ecological parks, artificial habitat, distribution patterns, dynamics communities
