The phenomenon of unequal usage of synonymous codons encoding an amino acid in which some codons are more preferred to others is the codon usage bias (CUB) and it is species specific. Analysis of CUB helps in understanding evolution at molecular level and acquires significance in mRNA translation, design of transgenes and new gene discovery. In our current study, we analyzed synonymous codon usage pattern and the factors influencing it on mitochondrial protein coding genes of 6 different hookworms i.e. Ancylostoma ceylanicum, Ancylostoma duodenale, Necator americanus, Ancylostoma tubaeforme, Ancylostoma caninum and Uncinaria sanguinis as no work was reported yet...

Worm infections continue to be among the most common diseases affecting children from low and middle income countries. Major worm infections of public health importance include Ascariasis, Trichuriasis, Hookworm, and Enterobiasis, which are transmitted through contaminated soil. In India, combined prevalence rates of worm infestation as per pooled data of 127 surveys is over 20%. Although most helminthic infections are mild and are often asymptomatic, but moderate to heavy worm infestations are generally associated with growth faltering, nutritional compromise, anemia and suboptimal academic performance among children from endemic regions...

Background: Human hookworm infection is caused mainly by Necator americanus and Ancylostoma duodenale. Among the zoonotic hookworm species, only Ancylostoma ceylanicum causes potent human infections where dogs and cats act as reservoir of infection. Hence, species differentiation is imperative because the eradication of both anthroponotic and zoonotic hookworm depends on the concurrent human and animal health programs, hygienic practices, and mass drug administration for humans and dogs...

Soil-transmitted helminths (STHs) include, i.e., hookworms (Ancylostoma duodenale, Necator americanus), roundworm (Ascaris lumbricoides), whipworm (Trichuris trichiura) and Strongyloides stercoralis. Globally, around 1.5 billion people are infected with STHs. STHs contribute to significant impairment of mental and physical growth, especially in developing countries. Unfortunately, these infections mostly remain undiagnosed due to lack of trained personnel and appropriate technologies. Intermittent shedding of eggs or larvae further makes the diagnosis difficult...

Soil-transmitted helminths (STH) consist of Ascaris lumbricoides, Trichuris trichiura, and hookworm (Necator americanus and Ancylostoma duodenale). It affects nearly 1.7 billion people globally in which Ascaris contributes nearly 1.2 billion cases. The main mode for transmission of Ascaris and Trichuris is through contaminated food and water, whereas hookworm transmitted by skin penetration. STH were mainly seen in areas with poverty, overcrowding, and poor sanitation. The prevalence is more in rural areas compared to urban areas...

Gastrointestinal parasites, hookworms in particular, have evolved to cause minimal harm to their hosts when present in small numbers, allowing them to establish chronic infections for decades. They do so by creating an immunoregulatory environment that promotes their own survival, but paradoxically also benefits the host by protecting against the onset of many inflammatory diseases. To harness the therapeutic value of hookworms without using live parasites, we have examined the protective properties of the recombinant protein anti-inflammatory protein (AIP)-1, secreted in abundance by hookworms within the intestinal mucosa, in experimental colitis...

Hookworm infection is a major tropical parasitic disease affecting almost 500 million people worldwide. These soil-transmitted helminths can survive for many years in the intestine of the host, where they feed on blood, causing iron deficiency anaemia and other complications. These parasites release a variety of molecules known as excretory/secretory products (ESPs) that are involved in many different biological processes that govern parasite survival. Using a combination of separation techniques such as SDS-PAGE and OFFGEL electrophoresis, in combination with state-of-the-art mass spectrometry we have reanalysed the dog hookworm, Ancylostoma caninum, ESPs (AcES)...
