Pure poly (ethylene oxide) (PEO) films and PEO-FeCl 3 films of various concentration were prepared and studied for thermal and optical properties. Various analytical techniques like XRD, EDX, SEM, TGA, and UV were used to examine the structural properties of PEO and PEO-FeCl 3 systems. X-ray scans (XRD) revealed the existence of some crystalline part in the PEO matrix. The concentration of FeCl 3 has a great effect on the crystallinity of PEO. Thermogravimetric analysis (TGA) data established that accumulation of FeCl 3 to PEO films enhanced the thermal stability of PEO. The optical properties of these systems were also studied in the UV-Visible region as a function of FeCl 3 concentration at room temperature.The obtained data were analyzed in terms of absorption formula for non-crystalline materials. From the measured absorption data optical energy gaps (E opt) were determined. The optical energy gap was found to decrease with the increase in FeCl 3 concentration, which indicates that FeCl 3 concentration had a significant influence on optical energy band gap. The absorption coefficient increased sharply at concentration of FeCl 3 (5%) wt as compared with the pure PEO.

The presence of potential vectors, ticks, and susceptible hosts of bovine malignant theileriosis in all parts of Iran pose a real threat to food animal industry. The present study was conducted to determine the infection rate of ticks collected from naturally occurring bovine theileriosis in West and North-West Iran. Two hundred and thirty seven cattle suspected of suffering from theileriosis were investigated for the presence of Theileria annulata in the blood smears and any tick species on their body. In this study, 402 ticks were obtained from 99 cattle. The examination of 402 ticks by polymerase chain reaction (PCR) using primers derived from the gene encoding heat shock protein70 (Hsp70) revealed that 39.9% of Hyalomma anatolicum anatolicum, 3.5% of H. asiaticum asiaticum, and 18.2% H. anatolicum excavatum, were infected with T. annulata. The results suggest that H. a. anatolicum may play a major role in transmission of T. annulata infection in Iran. Finally, digestion of the PCR products of T. annulata with two different restriction enzymes produced only a single pattern.

“…In general, the overall prevalence of T. annulata, except in buffaloes (15.5%), was above 60%, which is threefold higher than the prevalence rate of T. annulata (19%) recorded by others in the Indian subcontinent [17,18]. The prevalence of Anaplasma spp was also higher than other PCR surveys in South India [19].…”

In India, disease of cattle caused by tick-borne pathogens (TBP) constrains the rearing of high yielding Bos taurus dairy breeds that often develop clinical, fatal disease. Bos indicus and bufflao show resistance to TBP infection, and this has led to a policy of rearing crossbred indicus-taurus cattle. On dairy farms, co-grazing more resistant animals alongside crossbreeds could contribute positively (by removing potentially infective ticks) or negatively (by acting as a reservoir for infection). We investigated epidemiological factors that contribute to the prevalence of five tick-borne pathogens with links to milk-yield in co-grazed host types in dairy farms of two regions of Tamil Nadu, India; a region of high dairy production importance. A high prevalence of T. annulata and Anaplasma spp. was detected, but with lower prevalence in the Cauvery Delta than in the Northwestern zone. A strict host-type association with prevalence was observed: buffaloes had lower prevalence of TBP than cattle; and native breeds had a lower prevalence of Anaplasma spp. than crossbreeds. The results indicate that while susceptibility to becoming a carrier animal for TBP depends on exposure to ticks; aspects of resistance are determined by host type independent of tick exposure. There was no clear evidence that co-grazing, with more resistant host types, will provide a positive contribution (protective effect) to crossbreeds with greater milk productivity.
