background: heat shock protein 70 (hsp70) is present in all organisms studied so far, and is a major immunogen in infections caused by pathogens including leishmania spp. objective: the aim of this study was to clone and express hsp70 from l. infantum strain mcan/ir/96/lon-49 and evaluate antibody response against hsp70 in visceral leishmaniasis (vl). methods: the l. infantum hsp70 gene segment...

Toxoplasmosis is a common and widespread infection in humans and many other species of warm–blooded animals. Toxoplasma gondii-derived heat shock protein 70 (Hsp70) may play an important role in the virulence of Toxoplasma gondii (T. gondii). In the present study, T. gondii Hsp70 was amplified by polymerase chain reaction (PCR) from the DNA of the T. gondiitachyzoite RH strain through the use o...

abstract          background and objective: cutaneous leishmaniasis is a parasitic disease and a health problem in different parts of iran, especially two cities of mashhad and chabahar. due to morphological similarities of most leishmania species and difference in reservoirs of l. major and l. tropica, it is necessary to determine the parasite specie to combat the disease. thus, this study use...

Background: Vaccines capable of controlling tumor virus based infections are found difficult to develop due to the consistence latent infection in the host. DNA vaccines are attractive tools for the development of HPV vaccines and inducing antigen-specific immunity owing to the stability, simplicity of delivery, safety and cost effectiveness. However, there is a need to increase their potency b...

The objective of this study was to evaluate the effects inclusion a blend essential oils (capsaicin, carvacrol, cinnamaldehyde and eugenol) in broiler submitted thermal stress. Performance parameters gene expression heat shock protein (HSP70) were evaluated liver jejunum. Regarding performance, animals subjected stress had lower feed intake weight gain higher conversion. 3% increased HSP70 jeju...

heat shock proteins (hsps), are highly important due to their association with such economically important traits in animals as resistance to temperature shock and mastitis. in the current study, to get a comprehensive information on molecular structure and evolution of the hsp70s, and the available hsp70 sequences of the cattle and other animals taken from ncbi and aligned together. then, nucl...

The Escherichia coli dnaK gene is homologous to the major heat shock-induced gene in Drosophila (Hsp70). The primary DNA sequence of the entire protein-coding region of the dnaK gene was determined and compared with that of the Hsp70 gene of Drosophila. The two sequences are homologous; the dnaK gene could encode a 69,121-Da polypeptide, 48% identical to the hsp70 protein of Drosophila. The hom...
