Background & Objectives: Chlamydia spp. is an obligate intracellular agent that causes chlamydiosis in animals and humans. Chlamydia infections in cows can cause abortion, infertility and other symptoms. The aim of this survey was to investigate the frequency of chlamydia infection in sperm used by artificial insemination.Materials & Methods: In This survey semen samples were collected from semen supply centers. Then DNA was extracted using Cinnagen company kit. The samples were Analysed for the chlamydial agent by Nested polymerase chain reaction (Nested PCR) by 16SrRNA gene primer and then the PCR product was electrophoresed and positive samples were identified by genus and species.Results: The finding of this survey indicated the prevalence of infection of different chlamydial species in the sperm samples. A Total of 100 samples were tested, 23 samples were positive for chlamydia spp.which are 12 positive samples separately for Chlamydia Pecorum,Chlamydia abortus 7 positive samples and 4 positive samples were identified for Chlamydia Psitassi.Conclusion: The present survey showed that sperm samples can be an important source of chlamydial infection transmission in bulls.

Cadmium is one of the most important heavy metals in the soil that is environmentally important in humans and causes numerous health effects for humans. The aim of this study was to evaluate the effect of cyanobacteria Spirulina platensis (arthrospira platensis) on reduction of cadmium accumulation in liver and kidney of C57 mice.In this study, 16 C57 mice were randomly divided into 4 control and treatment groups. The control group was treated with physiological saline and the groups were treated with 1000 µg / ml cadmium chloride , 1% spirulina in diet and mixture cadmium and spirulina . On day 24, mices were killed after anesthesia with ether and cadmium levels in the feces, liver and kidney were measured by atomic absorption spectrophotometry.Cyanobacteria Spirulina platensis increased concentration of x percent cadmium excretion in the feces and reduce the heavy metal accumulation in mouse kidney C57 Y percent respectively.According to the findings of this study, it can be concluded that the use of this bacterium has a significant effect on decreasing digestive uptake of cadmium.
