Leishmaniasis, caused by intracellular protozoa of the genus, continues to be a global health issue, with approximately 700,000 to 1 million new cases occur annually worldwide. The disease is transmitted via the bite of infected female sand flies of the genus , resulting in a range of symptoms known as cutaneous, mucocutaneous, and visceral leishmaniasis. The species , discovered in 1995, has been linked to cases in individuals with HIV, presenting with diverse clinical pictures.

Quercetin is a kind of flavonoid with different biological effects including free radical scavenging and anti-microbial activity and this study is aimed to assess the anti-leishmania and anti-malarial effects of quercetin loaded phytosome and quercetin alone. In this experimental study, the in vitro activity of above drugs were measured using microscopically examinations and for evaluation the anti-leishmanial efficacy, the size of lesions were measured.

Growing of drugs resistance in parasites is one of the most threats to malaria control. The aim of study was to investigate the anti-malarial activity of nano-emodin isolated from on in mice to evaluate parasites inhibition rate using test.

Antimicrobial photodynamic therapy (aPDT) inhibits quorum quenching (QQ), and can be used to prevent microbial biofilm. We thereby aimed to evaluate the anti-biofilm potency and anti-metabolic activity of nano-quercetin (N-QCT)-mediated aPDT against S.

Low efficacy and high cytotoxicity of the current treatment regimens for leishmaniasis is one of the most important health problems. In this experimental study, anti-leishmanial effects of different concentrations of resveratrol and resveratrol nano-emulsion (RNE) were assessed.

Herbal therapy is the ideal treatment for CL because of the reduced injection pain, availability, lower cost and non-toxicity effects. The present study aimed to evaluate the in vivo antileishmanial activity of concocted herbal topical preparation (Aloe vera, Perovskia abrotanoides, Nigella sativa, propolis, lavender and olive oil) to evaluate its efficacy against Leishmania major (MRHO/IR/75/ER) in comparison to the gold standard treatment.

This study aimed to explore the anti-biofilm efficacy of sonodynamic therapy (SDT) using nano-emodin (N-EMO) against multi-species bacterial biofilms containing Staphylococcus aureus, Pseudomonas aeruginosa, and Acinetobacter baumannii.
Methods: Following synthesis and confirmation of N-EMO as a sonosensitizer, the anti-biofilm efficacy of SDT against multi-species bacterial biofilms was determined using minimum inhibitory concentrations (MIC), minimum biofilm inhibitory concentration (MBIC), and minimal biofilm eradication concentration (MBEC) of N-EMO.

In this investigation, we systematically reviewed the distribution of anaplasmosis among domestic ruminants in Iran. Five and four English and Persian databases were studied, respectively, based on keywords and throughout 17 years (2001-2017).

Nanotechnology has provided novel approaches to synthesize nano-drugs to improve efficient antipathetic treatment.
Purpose: Nano-chitosan as a nontoxic antimicrobial agent was examined against three most prevalent protozoa in humans, Plasmodium falciparum, Giardia lamblia and Trichomonas vaginalis.
Aim: The aim of the current study is to evaluate the prevalence of trichomoniasis in men and women in the north of Iran and to find genotypes in the positive clinical specimens based on T. vaginalis actin gene.
Materials And Methods: Women's genital (n = 500) and men's urine (n = 1500) samples were collected from the participants referred to clinics in Mazandaran Province, northern Iran, during 2006-2018.
