Article Synopsis
- - The introduction of the non-native winter crane fly, Trichocera maculipennis, in maritime Antarctica may threaten the unique local ecosystem, which is vulnerable to foreign species.
- - Researchers conducted tests using advanced methods to determine if T. maculipennis could mechanically transmit various viruses, and identified several human and plant virus genomic fragments in samples collected from the fly.
- - Although the study found low amounts of human adenovirus and retrovirus in the fly samples, which were non-viable, it highlights the need for ongoing research into the impacts of non-native species on Antarctic ecosystems.
Unlabelled: Current influenza A vaccines fall short, leaving both humans and animals vulnerable. To address this issue, we have developed attenuated modified live virus (MLV) vaccines against influenza using genome rearrangement techniques targeting the internal gene segments of FLUAV. The rearranged M2 (RAM) strategy involves cloning the M2 ORF downstream of the PB1 ORF in segment 2 and incorporating multiple early stop codons within the M2 ORF in segment 7.

The most common bacteria causing TD is enterotoxigenic Escherichia coli (ETEC). The WC/rBS cholera vaccine (Dukoral) has been shown to induce cross-protection against ETEC by means of the B subunit of the cholera toxin.

The aim of the study presented here was to assess the incidence of histoplasma infection in a cohort of 342 individuals in Spain who had traveled to Latin America for the first time. The histoplasmin skin test was positive in 20% of the travelers, and Central America posed a higher risk for infection than South America (p=0.013).

Objective: To analyze the epidemiological and clinical characteristics of Histoplasma capsulatum infection in a group of volunteers who had traveled to Guatemala.
Methods: A review was performed of the clinical records of nine patients who consulted at the Tropical Medicine Outpatient Unit of Hospital Clinic in Barcelona, Spain. RESULTS.
Background: To evaluate the frequency and type of adverse drug reactions associated to the antimalarial chemoprophylaxis advised to travellers visiting endemic areas.
Subjects And Methods: We included the travellers who from july 1992 to june 1994 came to the Travellers Advise Department and made short-term travels to areas with malarial infection risk. The adverse drug reactions were reported by the travellers through a questionnaire handed at the consulting room.
Background: Swimming in rivers or lakes is a risk activity, in areas where the life cycle of schistosomiasis occurs. This report presents and analyzes the clinical presentation and epidemiological data of 80 Spanish travellers.
Patients And Methods: Descriptive longitudinal and retrospective study that includes clinicoepidemiological and the laboratory data and imaging diagnosis.
