ABSTRACT

Coxiella burnetii, the causative agent of Q fever, causes abortions in animals. Its effects on humans and the management of Q fever in certain conditions like pregnancy are undetermined. The World Health Organization has estimated that zoonotic diseases cause around one billion cases of infections and millions of deaths globally each year. It is worth noting that many emerging infectious diseases currently being reported worldwide are zoonoses. We reviewed studies reporting on Q fever prevalence and incidence in Europe. Articles from 1937 to 2023 with the following terms "Coxiella burnetii and Europe and Q fever, and seroprevalence studies" were identified in the PubMed database and reports by organizations such as the European Centre for Disease Prevention and Control (ECDC). We included randomized and observational studies, seroprevalence studies, case series, and case reports. According to the ECDC in 2019, 23 countries reported 1069 cases, the majority of which were classified as confirmed cases. The number of reports per 100,000 inhabitants in the EU/EEA was 0.2 for 2019, the same as the previous four years. The highest report rate (0.7 cases per 100,000 population) was observed in Spain, followed by Romania (0.6), Bulgaria (0.5), and Hungary. Considering the typically asymptomatic nature of Q fever infection, it is imperative to strengthen the existing systems to promote the rapid identification and reporting of Q fever outbreaks in animals, particularly in cases of abortion. It is also essential to consider the facilitation of early information exchange between veterinarians and public health counterparts to ensure the timely detection and prevention of potential zoonotic events, including Q fever.

ABSTRACT

Human health is at risk because commensal intestinal bacteria in livestock have been developing increased antibiotic resistance, mainly due to antibiotics' extensive use in recent years. In this study, we compared the antibiotic resistance of E. coli strains isolated from fecal samples obtained from swine, poultry, and farm workers in the corresponding livestock farming units. The study aimed to investigate the correlation between the antibiotic resistance patterns of E. coli in livestock and in humans closely interacting with them. Antibiotic resistance is determined using the microdilution method, which measures the minimum inhibitory concentration (MIC) for seven commonly used antimicrobial agents. Most E. coli isolates displayed significant resistance to tetracycline and ampicillin. Resistance to sulfamethoxazole was observed, too, in swine and swine farmers. In contrast, high resistance rates to nalidixic acid were observed in E. coli strains isolated from poultry and poultry farmers, with percentages of 66.7% and 50%, respectively. Furthermore, 31.57% of the isolated strains from swine and swine farmers were resistant to at least one antibiotic. In comparison, 44.44% of the poultry strains and 33.33% of the poultry farmers' strains were resistant to at least two antibiotics. Additionally, a high prevalence of multidrug resistance was observed among the E. coli strains isolated from all four categories. The study's results provide evidence that the use of antibiotics and the increased resistance of intestinal bacteria affect the resistance of intestinal bacteria in people working on farms. These findings highlight the potential role of antibiotic use in animals as a contributing factor to the development of antibiotic resistance in both animals and humans. Additionally, it suggests that individuals working on farms may be at an increased risk of acquiring antibiotic-resistant strains of E. coli due to their proximity to and interaction with animals.

ABSTRACT

Caridina sobrina Riek, 1953, only known from Fraser Island (Queensland, Australia), is redescribed and elevated from subspecies to species level. A morphologically very similar species, Caridina pagei sp. nov., is described from nearby Moreton Island. The taxon known in previous literature as Caridina sp. C2 is also illustrated but left unnamed in view of its complete morphological overlap with C. pagei, despite substantial genetic drift.

ABSTRACT

Life at hydrothermal vent sites is based on chemosynthetic primary producers that supply heterotrophic microorganisms with substrates and generate biomass for higher trophic levels. Often, chemoautotrophs associate with the hydrothermal vent megafauna. To investigate attached bacterial and archaeal communities on deep-sea squat lobsters, we collected ten specimens from a hydrothermal vent in the Guaymas Basin (Gulf of California). All animals were identified as Munidopsis alvisca via morphological and molecular classification, and intraspecific divergence was determined. Amplicon sequencing of microbial DNA and cDNA revealed significant differences between microbial communities on the carapaces of M. alvisca and those in ambient sea water. Major epibiotic bacterial taxa were chemoautotrophic Gammaproteobacteria, such as Thiotrichaceae and Methylococcaceae, while archaea were almost exclusively represented by sequences affiliated with Ca. Nitrosopumilus. In sea water samples, Marine Group II and III archaea and organoheterotrophic Alphaproteobacteria, Flavobacteriia and Planctomycetacia were more dominant. Based on the identified taxa, we assume that main metabolic processes, carried out by M. alvisca epibiota, include ammonia, methane and sulphide oxidation. Considering that M. alvisca could benefit from sulphide detoxification by its epibiota, and that attached microbes are supplied with a stable habitat in proximity to substrate-rich hydrothermal fluids, a mutualistic host-microbe relationship appears likely.

ABSTRACT

BACKGROUND: The growing interest in mineral resources of the deep sea, such as seafloor massive sulphide deposits, has led to an increasing number of exploration licences issued by the International Seabed Authority. In the Indian Ocean, four licence areas exist, resulting in an increasing number of new hydrothermal vent fields and the discovery of new species. Most studies focus on active venting areas including their ecology, but the non-vent megafauna of the Central Indian Ridge and South East Indian Ridge remains poorly known.In the framework of the Indian Ocean Exploration project in the German license area for seafloor massive sulphides, baseline imagery and sampling surveys were conducted yearly during research expeditions from 2013 to 2018, using video sledges and Remotely Operated Vehicles. NEW INFORMATION: This is the first report of an imagery collection of megafauna from the southern Central Indian- and South East Indian Ridge, reporting the taxonomic richness and their distribution. A total of 218 taxa were recorded and identified, based on imagery, with additional morphological and molecular confirmed identifications of 20 taxa from 89 sampled specimens. The compiled fauna catalogue is a synthesis of megafauna occurrences aiming at a consistent morphological identification of taxa and showing their regional distribution. The imagery data were collected during multiple research cruises in different exploration clusters of the German licence area, located 500 km north of the Rodriguez Triple Junction along the Central Indian Ridge and 500 km southeast of it along the Southeast Indian Ridge.

ABSTRACT

A new species of Alpheus, A. samudra nov. sp., is described from the bycatch of trawlers operating between 275-375 m depth on the Quilon Bank (Kerala, India). The new species belongs to the brevirostris group, but can be easily distinguished from all but one species, by the extremely laterally compressed major cheliped. Alpheus samudra nov. sp. is very similar to A. leptocheles Banner Banner, 1975 in the form of the major cheliped, but the proportions of the fingers to the palm and the shape of the fingers easily separate both species.

ABSTRACT

The seafloor contains valuable mineral resources, including polymetallic (or manganese) nodules that form on offshore abyssal plains. The largest and most commercially attractive deposits are located in the Clarion Clipperton Fracture Zone (CCZ), in the eastern Pacific Ocean (EP) between Hawaii and Mexico, where testing of a mineral collection system is set to start soon [1]. The requirement to establish pre-mining environmental management plans has prompted numerous recent biodiversity and DNA barcoding surveys across these remote regions. Here we map DNA sequences from sampled ophiuroids (brittle stars, including post-larvae) of the CCZ and Peru Basin onto a substantial tree of life to show unprecedented levels of abyssal ophiuroid phylogenetic diversity including at least three ancient (>70 Ma), previously unknown clades. While substantial dark (unobserved) biodiversity has been reported from various microbial meta-barcoding projects [2, 3], our data show that we have considerably under-estimated the biodiversity of even the most conspicuous mega-faunal invertebrates [4] of the EP abyssal plain.

ABSTRACT

Atyaephyra stankoi's Karaman 1972 syntypic material has been assumed to be lost. However, M. Karaman's type material has been found within the zoological collections of the University of Novi Sad, Serbia and thus a lectotype is herein designated, while placing aside the designated neotype. An updated distribution of A. stankoi in Greece and F.Y.R.O.M. is provided based on field collections and literature data, while support is provided by COI data. Furthermore, new records in Peloponnesus and Attica expand the known distribution of species in Greece. Finally some preliminary insights are given on the species zoogeography, while there seems to be a correspondence between genetic haplotype groups and geographical location.

ABSTRACT

BACKGROUND: This paper describes a dataset of macrofaunal organisms associated with the sponge Sarcotragus foetidus Schmidt, 1862, collected by scuba diving from two sampling sites: one in Greece (North Aegean Sea) and one in Cyprus (Levantine Sea). NEW INFORMATION: This dataset includes macrofaunal taxa inhabiting the demosponge Sarcotragus foetidus and contributes to the ongoing efforts of the Ocean Biogeographic Information System (OBIS) which aims at filling the gaps in our current knowledge of the world's oceans. This is the first paper, to our knowledge, where the macrofauna associated with S. foetidus from the Levantine Basin is being recorded. In total, 90 taxa were recorded, from which 83 were identified to the species level. Eight of these species are new records for the Levantine Basin. The dataset contains 213 occurrence records, fully annotated with all required metadata. It is accessible at http://lifewww-00.her.hcmr.gr:8080/medobis/resource.do?r=organismic_assemblages_sarcotragus_foetidus_cyprus_greece.

ABSTRACT

Atyaephyra de Brito Capello, 1867 was described from the Mediterranean region almost 200 years ago. Since then, the genus has been recorded from various freshwater habitats in Europe, North Africa and the Middle East. Despite its long history, the taxonomic status of Atyaephyra species remains confusing and uncertain. Consequently numerous specimens from the known range of Atyaephyra were analysed using morphological characters and mitochondrial COI sequences in an attempt to clarify the taxonomy of this genus. The present study recognises seven Atyaephyra species, more than twice as many as previously recorded (three), four of which are considered as new. The new species are described, additional information to the original descriptions are provided for the remaining three taxa, while neotypes of Atyaephyra desmarestii Millet, 1831 and Atyaephyra stankoi Karaman, 1972 are designated to stabilize their taxonomy. Non-overlapping distinguishing morphological characters are used to discriminate the examined material into five species, e.g., Atyaephyra desmarestii, Atyaephyra stankoi, Atyaephyra orientalis Bouvier, 1913, Atyaephyra thyamisensissp. n., Atyaephyra strymonensissp. n. In addition, the genetic analysis supports the existence of multiple phylogenetic clades in the broader Mediterranean area and distinguishes two new cryptic species, namely Atyaephyra tuerkayisp. n. and Atyaephyra acheronensissp. n. The geographic distribution of these species is confirmed and their phylogenetic relationships are described.
