Acanthocephalans as pollutant sinks? Higher pollutant accumulation in parasites may relieve their crustacean host.

Increasing chemical pollution calls for a closer look at ecologically highly relevant host-parasite interactions to understand the persistence of organisms and populations in a polluted environment. The impact of chemical exposure within the host-parasite interactions - particularly the distinctive bioaccumulation behavior of organic micropollutants - can substantially influence the persistence of a species. This significance has been emphasized by previous research showing a higher tolerance of Gammarus roeselii (Amphipoda, Crustacea) infected with acanthocephalans during acute exposure to a pyrethroid.

Phage susceptibility testing methods or 'phagograms': where do we stand and where should we go?

Phage therapy is a highly promising approach to address the challenge that is presented by the global burden of antimicrobial resistance. Given the natural specificity of phages, phage susceptibility testing (PST) is a prerequisite for successful personalized therapy, allowing the selection of active phages from large and diverse collections. However, the issue of an easy-to-use and standardized technique remains.

Cryptic species complex shows population-dependent, rather than lineage-dependent tolerance to a neonicotinoid.

Cryptic species are rarely considered in ecotoxicology, resulting in misleading outcomes when using a single morphospecies that encompasses multiple cryptic species. This oversight contributes to the lack of reproducibility in ecotoxicological experiments and promotes unreliable extrapolations. The important question of ecological differentiation and the sensitivity of cryptic species is rarely tackled, leaving a substantial knowledge gap regarding the vulnerability of individual cryptic species within species complexes.

Syphilis Should not be Overlooked in any Individual, Irrespective of their Condition.

Introduction: Syphilis remains a significant challenge in public health, largely because of its diverse clinical manifestations, often resulting in underdiagnosis especially among patients with neurogenic disability.

Case Description: We present a case of neurosyphilis in a 63-year-old patient with a spinal cord injury. Despite syphilis being a well-established sexually transmitted infection, the exacerbation of neurological and dermatological symptoms during physical examination prompted an investigation into alternative causes beyond the patient's pre-existing paraparesis, ultimately resulting in the diagnosis of neurosyphilis.

One like all? Behavioral response range of native and invasive amphipods to neonicotinoid exposure.

Native and invasive species often occupy similar ecological niches and environments where they face comparable risks from chemical exposure. Sometimes, invasive species are phylogenetically related to native species, e.g.
