Climate change has been predicted to increase the global mean temperature and to alter the ecological interactions among organisms. These changes may play critical roles in influencing the life history traits of the intermediate hosts (IHs). This review focused on studies and disease models that evaluate the potential effect of temperature rise on the ecology of IH snails and the development of parasites within them. The main focus was on IH snails of schistosome parasites that cause schistosomiasis in humans...

Haemonchus contortus is one of the most significant strongylid nematodes infecting small ruminants and causes great economic losses to the livestock industry worldwide. Accurate diagnosis of H. contortus is crucial to control the infection. Traditional microscopic examinations are the most common methods for the diagnosis of H. contortus, but they are time-consuming and inaccurate. Molecular methods based on PCR are more accurate, but need expensive machines usually only used in the laboratory. Loop-mediated isothermal amplification (LAMP) is a rapid, simple, specific and sensitive method that has been widely used to detect viruses, bacteria and parasites...

The study presented here aimed at identifying a new class of compounds acting against Leishmania parasites, the causative agent of Leishmaniasis. For this purpose, the thioether derivatives of our in-house library have been evaluated in whole-cell screening assays in order to determine their in vitro activity against Leishmania protozoan. Among them, promising results have been achieved with compound RDS 777 (6-(sec-butoxy)-2-((3-chlorophenyl)thio)pyrimidin-4-amine) (IC50 = 29.43 µM), which is able to impair the mechanism of the parasite defence against the reactive oxygen species by inhibiting the trypanothione reductase (TR) with high efficiency (Ki 0...

I give an historical account and analysis of the scientific priority of the discovery of the polychrome staining of microscopic biological preparations provided by mixtures of eosin plus methylene blue and its derivatives, especially azure B. I maintain that both the formal priority for the discovery of the polychrome staining phenomenon and credit for initiating the development of a technique of polychrome staining properly belong to D. L. Romanowsky. His scientific work demonstrated the possibility of using a simple technique to stain hematological preparations selectively to give good contrast, high resolution and the ability to identify malaria parasites...

Since its introduction into Europe the invasive Drosophila suzukii has established and spread widely, thereby entering habitats populated by native Drosophila species and their natural enemies. The highly prolific D. suzukii will likely interact with these species as a competitor, host or prey. To investigate potential interactions of D. suzukii with parasitoids, a field survey was conducted across several fruit-growing regions in Switzerland in two consecutive years. Eight species of hymenopteran parasitoids were collected using D...

OBJECTIVE: Antimicrobial resistance (AMR) is an increasing global problem. AMR threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi. The misuse and overuse of antibiotics (AB) is the major contributor to the emergence of resistant bacteria in humans. To present and describe characteristics in parents' knowledge about when and how to use AB for an upper respiratory tract infection (URTI), their attitudes towards doctors and AB use in general, and their behaviour when their child suffers from an URTI...

Wolbachia is possibly the most studied reproductive parasite of arthropod species. It appears to be a promising candidate for biocontrol of some mosquito borne diseases. We begin by developing a sex-structured model for a Wolbachia infected mosquito population. Our model incorporates the key effects of Wolbachia infection including cytoplasmic incompatibility and male killing. We also allow the possibility of reduced reproductive output, incomplete maternal transmission, and different mortality rates for uninfected/infected male/female individuals...

The present study characterized Argulus spp. infecting the cultured carps using 18S rRNA gene sequences, estimated the genetic similarity among Argulus spp. and established their phylogenetic relationship. Of the 320 fish samples screened, 34 fish (10.6%) had Argulus infection. The parasitic frequency index (PFI) was observed to be high (20%) in Hypophthalmichthys molitrix and Labeo bata. The frequency of infection was high in September (PFI: 17%) and October (PFI: 12.9%). The 18S rRNA sequences of five A. bengalensis (KF583878, KF192316, KM016968, KM016969, and KM016970) and one A...

Hydatid disease is a rare parasitic disease, which mainly involves liver then lung tissues. Cardiac involvement is very rare, especially when there is not hepatic involvement. We describe a 47-year-old woman with a history of a lung hydatid cyst who was referred to Rajaei Heart Center, Tehran, Iran in 2012. Her chest computed tomographic scan showed a cardiac mass. Echocardiographic examination illustrated a large, well-defined heterogeneous mass (4.5 × 2.5 cm) in the roof of the right atrium with attachment to the crista terminalis without compressive effect on the inferior and superior venae cavae...

BACKGROUND: Anisakid nematodes are common parasites of fish, mammals, fish-eating birds, and reptiles with a worldwide distribution, causing diseases in human, fish and important economic losses. METHODS: A preliminary epidemiological study was carried out on Anisakid nematodes larvae in some commercially important fish species to evaluate the anisakid nematode larvae from greater lizardfish, (Saurida tumbil), Japanese thread fin bream (Nemipterus japonicus), crocodile longtom (Tylosurus crocodilus crocodiles) and longfin trevally (Carangoides armatus) from the Persian Gulf of Iran...

BACKGROUND: Intestinal parasitic infections have a worldwide distribution. High prevalence of intestinal parasitic infections in individuals with low socioeconomic status and environmental conditions was found. No study has ever been conducted on the prevalence of these infections in Jiroft. Therefore, in this study prevalence of intestinal parasitic infections was evaluated in Jiroft, Kerman Province, Iran. METHODS: A total of 1060 individuals from rural and urban areas of Jiroft were sampled accidentally, during 2013-2014...

BACKGROUND: Toxoplasma gondii is the most common parasite causing latent cerebral infections in human. It has been shown that some anti-psychotic drugs are able to inhibit the proliferation of the parasite in in vitro study. There is very limited data regarding the inhibitory effect of anti-psychotics on Toxoplasma in in vivo. In this study, we evaluated anti-Toxoplasma activity of fluphenazine and thioridazine drugs on T. gondii in mice. METHODS: Mice were divided into six groups: Control, sesame as vehicle, thioridazine 10 mg/kg, thioridazine 20 mg/kg, fluphenazine 0...

About one-half of all Burkitt lymphoma (BL) patients are younger than 40 years, and one-third belong to the adolescent and young adult (AYA) subset, defined by an age between 15 and 25-40 years, based on selection criteria used in different reports. BL is an aggressive B-cell neoplasm displaying highly characteristic clinico-diagnostic features, the biologic hallmark of which is a translocation involving immunoglobulin and c-MYC genes. It presents as sporadic, endemic, or epidemic disease. Endemicity is pathogenetically linked to an imbalance of the immune system which occurs in African children infected by malaria parasites and Epstein-Barr virus, while the epidemic form strictly follows the pattern of infection by HIV...
