The purpose of this study was to determine the 50% infective dose for Giardia lamblia (CDC:0284:1) cysts in Mongolian gerbils (Meriones unguiculatus). The log10 50% infective dose results calculated by probit analysis and the Spearman-Karber method were 2.45 and 2.50, respectively.

  White Spot Virus (WSV) is currently the most serious viral pathogen of shrimp worldwide it causes mortality up to 100% within 7-10 days in commercial shrimp farms. Infected Indian white shrimp Fenneropenaeus indicus samples were collected from Guatr shrimp site in Sistan and Baluchestan province in south of Iran and WSV infection was confirmed by Nested PCR. WSV was isolated from infected shr...

Methods Prospective observational study. Plasmatic levels of ProADM, C reactive protein (CRP) and procalcitonin (PCT) and lactate in 110 consecutive patients admitted to ICU with severe sepsis / septic shock at days 1, 3 and 7 after admission. Clinical and demographic data: age, gender, comorbidities, APACHE II and SOFA scores. Recruited period over 12 months. Statistical analysis: c test for c...

In this study, the effects of different concentrations of pyrene, phenanthrene, fluoranthene, and chrysene within the solubility limits of the chemicals on marine microalgal species of Phaeodactylum tricornutum were examined under UV-A and UV-B lights by application of batch toxicity tests. The algal species were also exposed to the individual PAHs under cool-white fluorescent bulbs in the same...

This experiment was conducted to assess the efficacy of typhoid vaccine newly produced by purifying Vi antigen of Salmonella typhi. With Karber method, LD50 of challenging organism (S. typhi ty2) was determined as 6.31 CFU/mouse, and then the organism was used for the study. With Probits method, ED50 of the vaccine was determined as 0.016 microg / 0.5 ml / mouse. The ELISA titer (0.5097+/-0.060...

Th e acute toxicities of cadmium chloride (CdCl2.H2O), arsenic trioxide (AS2O3), and their mixtures to Daphnia magna were investigated by employing the statistical method of aquatic toxicity. Th e data obtained were statistically evaluated with probit analysis method (SPSS 17.0). Th e 24 h LC50 of Cd and As to Daphnia magna was estimated to be 44 μg L−1 for Cd, and 509 μg L−1 for As, respective...

Bacterial and fungal pathogens in recirculating aquaculture egg incubation systems can cause elevated mortality decreased production. Peracetic acid (PAA) is a relatively low-cost, safe, effective disinfectant; however, its toxicity to early life stages of the Atlantic salmon (Salmo salar) has not been assessed. The 24-h LC50 value PAA was determined for three salmon: eyed eggs, fry (~0.17 g), ...

Monoclonal (MAb 362.50) and polyclonal (anti-gpl05-2) antibodies have been used to examine the expression by transplantable (II 1C) and primary (PI 1C) hepatocellular carcinomas of a 105 kd rat hepatocyte cell adhesion molecule designated cell-CAM 105. Two-dimensional gel analy sis of components immunoprecipitated with MAb 362.50 or anti-gpl052 antibodies from detergent extracts of cells surfac...
