Ticks and tick-borne diseases.

Ticks and tick-borne diseases. Med Mal Infect. 2019 Feb 05;: Authors: Boulanger N, Boyer P, Talagrand-Reboul E, Hansmann Y Abstract Ticks are a major group of arthropod vectors, characterized by the diversity of pathogens they transmit, by their impact on human and animal health, and by their socioeconomic implication especially in countries of the Southern Hemisphere. In Europe, Ixodes is the most important tick due to its wide distribution in the ecosystems and the variety of transmitted pathogens, in particular Borrelia (responsible for Lyme borreliosis), but also the tick-borne encephalitis virus. Their increased presence in the environment since the beginning of the 20th century is undeniable, because of major modifications in the biodiversity caused by humans. Increasing the awareness of health professionals and the general population is required to achieve better control of these infections. Thus, "a better understanding of these tick-borne diseases for a better control" is a simple but effective approach, considering their ubiquity in the environment and their particular mode of pathogen transmission (long-lasting blood meal for hard ticks and delayed transmission for bacteria and parasites). Finally, these ectoparasites are problematic due to the potential allergic reactions and other damages caused by their saliva, in humans and animals.

We present a 20-year-old male patient who presented himself after a car accident, and was diagnosed with a rupture of traumatic hydatid cysts due to hives rash. In the operation, a scolicidal gent was administered to the cyst, the cyst wall was partially excised and the germinative membranes were removed. Medical treatment with albendazole was started. The postoperative period was quiet. The intraperitoneal traumatic rupture of a hydatid cyst is rare, but it can cause severe anaphylactic reactions and biliary peritonitis. Although a rare and broken hydatid cyst due to trauma may present with skin lesions in a patient in an...

Publication date: Available online 21 February 2020Source: Urology Case ReportsAuthor(s): Leila Haghighi, Mohsen Akbaribazm, Zahra Arab-Mazar, Mohsen RahimiAbstractHematobium species of this parasite tends to bladder and mesenteric arteries and it causes lesions in the bladder wall, urethra, and renal tubes. A 25-year-old man living in Tehran (a non-endemic and very rare area for schistosoma) suffers from symptoms such as hematuria with suprapubic pain, dysuria, fever, nausea and vomiting. Urine analysis showed a lot of red blood cells, after using cystoscopy of the area and receiving a bladder biopsy, a definitive diagnos...

Abstract Parasitic diseases are a serious public health problem affecting hundreds of millions of people worldwide. African trypanosomiasis, American trypanosomiasis, leishmaniasis, malaria and toxoplasmosis are the main parasitic infections caused by protozoan parasites with over one million deaths each year. Due to old medications and drug resistance worldwide, there is an urgent need for new antiparasitic drugs. 1,3,4-Thiadiazoles have been widely studied for medical applications. The chemical, physical and pharmacokinetic properties recommend 1,3,4-thiadiazole ring as a target in drug development. Many scienti...

This study aimed to characterize HVL in its epidemiological andtemporal aspects in Ceara State, from 2003 to 2017, as this is a neglected disease and a public health problem. This is an ecological study carried out with HVL confirmed cases in Ceara, using three blocks of years (2003 to 2007, 2008 to 2012 and 2013 to 2017). The disease presented an endemic behavior, affecting mainly male residents in the urban area, especially children under five and young adults between 30 and 49 years old. HVL is recorded in all the municipalities, for more than 10 years, with a growing trend and territorial expansion to the Central and E...

der F Abstract Introduction: Despite advancements in diagnostic capabilities and the availability of effective antimicrobial agents, community-acquired infections of the central nervous system (CNS) are still associated with high mortality rates. Aim: To assess the epidemiological and clinical characteristics of community-acquired CNS infections treated in the West Pannonian region between 2010 and 2016. Method: Clinical data of 176 patients were retrospectively analysed in two age cohorts: 15 to 65 and more than 65 years of age. Results: Neuroinfections were found to be bacterial in 81, viral in 91, parasitic in ...

In this study, the prevalence of antibodies against two Babesia spp. was investigated in a cohort of patients that were seropositive for Borrelia (B.) burgdorferi sensu lato (s.l.). Data were compared to a control group of healthy individuals. Sera were collected from 283 individuals residing in the southernmost region of Sweden, Skåne County. Almost one third of the sera were from patients with a confirmed seropositive reaction against B. burgdorferi s.l. All sera samples were assessed for IgG antibodies against Babesia (Ba.) microti and Ba. divergens by indirect fluorescent antibody (IFA) assays. Seropositive IgG t...

Ticks and the diseases they carry have long been recognized as health concerns, especially in the warmer months when ticks (and humans) are more active. Ticks wait on grass tips or shrubs to latch onto new hosts when they brush by. Most of the hosts are animals, but a few tick species do bite and feed on humans. While doing so, they can transmit bacteria and viruses through their saliva. But here’s what’s changing: Tick species are being found in a wider geographic range. The number of case reports of tick-borne illnesses is increasing. Scientists continue to identify new pathogens (bacteria and viruses that c...
