Neglected tropical diseases as termed by World Health Organization include a group of 20 diverse infectious diseases in the tropical and subtropical regions of the world. Amongst these diseases, high mortality rate is mostly associated with Chagas disease and leishmaniosis due to limited drugs, severe toxicity caused by the available drugs and drug resistance. The above hitches have triggered the researchers to focus on the development of novel alternative therapeutics. Studies reveal that several target-based drugs have emerged which affect the biochemical pathways of the causative parasite...

Bison bonasus (Linnaeus, 1758) and B. bison (Linnaeus, 1758) are mammals placed in the Red Book of the International Union for Conservation of Nature. Populations of those species of animals are under threat of extinction. Therefore, developing practical measures for their protection is of great significance. However, one way of improving the population of bisons is integrated control of their helminths. The article generalizes the data about the helminth fauna of B. bonasus and B. bison, as well as data on relatively medicinal plants with anthelmintic properties...

Trichomonas vaginalis (TV) is the most common non-viral sexually transmitted infection (STI) microaerophilic protist parasite, which is the causative agent of trichomonosis. Globally, the estimated annual incidence is more than 270 million cases. It is correlated for several health problems including pelvic inflammatory disease (PID), pregnancy miscarriages, cervical carcinoma, prostatitis, prostatic adenocarcinomas, infertility, and the acquisition of human immunodeficiency virus (HIV). Most individuals infected with TV are asymptomatic...

Cystoisospora belli is an obligate intracellular coccidian parasite known to cause chronic persistent diarrhoea in immunocompromised individuals such as human immunodeficiency virus (HIV) infection, long term corticosteroid therapy, cancer chemotherapy and solid organ transplant recipients. Trichuris trichiura is a soil transmitted helminth, which predominantly causes asymptomatic or mild infections but heavy worm load can sometimes lead to chronic diarrhoea, tenesmus or rectal prolapse. We report a case of co-infection with Cystoisospora belli and Trichuris trichiura in an adult patient causing intractable diarrhea, which led to the unraveling of a severely compromised immune status in the patient enabling an appropriate therapeutic approach and further management...

Blastocystis hominis is an intestinal protozoan that inhabits the large intestine of humans and a wide range of animals. Blastocystis species has a worldwide distribution. The current study aimed to determine the prevalence and the genetic variety of Blastocystis sp. in Iraqi children in Salah AL-Deen province, Iraq. 150 faecal samples were collected from children (5-10 years old) who attended the Salah AL-Deen hospital during the period from March to November 2020. The results revealed that 33.3% of children (50 out of 150) were found infected with Blastocystis sp...

Abortion is a condition that occurs due to one of the pathological injuries, often one of the members of the TORCH is the real cause. The current study aimed to investigate the impact of toxoplasmosis, HSV-2 infections with abortion, and also, the identification of immunogenetics marker (interleukin-10) that may be associated with abortion. Anti-Toxoplasma IgG, IgM, Herpes simplex virus-2 IgM, human soluble leukocyte antigen class I-G and interleukin-10 were estimated by ELISA technique, while the expression of IL-10 gene was investigated by using the real-time PCR...

Aedes albopictus (Diptera: Culicidae) is one well-established vector of a series of mosquito-borne diseases. The larval stage of their life cycle is best suited to control a large population of mosquitoes easily. Controlling the larval stage of such vectors can also control the spread of the pandemic disease through the vector. Larvicides, which are synthetic, is a promising solution now. This kind of synthetic larvicides affects humans and animals equally and damages the environment through unscientific and widespread use...

Toxoplasma gondii (T. gondii) is a ubiquitous, opportunistic organism, which actually infects all warmblooded animals.
