Bactericidal synergism between phage endolysin Ply2660 and cathelicidin LL-37 against vancomycin-resistant Enterococcus faecalis biofilms.

Antibiotic resistance and the ability to form biofilms of Enterococcus faecalis have compromised the choice of therapeutic options, which triggered the search for new therapeutic strategies, such as the use of phage endolysins and antimicrobial peptides. However, few studies have addressed the synergistic relationship between these two promising options. Here, we investigated the combination of the phage endolysin Ply2660 and the antimicrobial peptide LL-37 to target drug-resistant biofilm-producing E.

from Samples of Commercially Reared Turkeys: Genomic Relationships, Antimicrobial and Biocide Susceptibility.

is especially known as a cause of nosocomial infections worldwide. It shows intrinsic and acquired resistances to numerous antimicrobial agents, which can render the treatment difficult. In contrast to the situation in human medicine, there are only few studies focusing on among livestock.

Next-generation humanized NSG-SGM3 mice are highly susceptible to infection.

Humanized hemato-lymphoid system mice, or humanized mice, emerged in recent years as a promising model to study the course of infection of human-adapted or human-specific pathogens. Though infects and colonizes a variety of species, it has nonetheless become one of the most successful human pathogens of our time with a wide armory of human-adapted virulence factors. Humanized mice showed increased vulnerability to compared to wild type mice in a variety of clinically relevant disease models.

Molecular phylogenetics of the sucking louse genus (Insecta: Phthiraptera), ectoparasites of lemurs, with descriptions of three new species.

Sucking lice live in intimate association with their hosts and often display a high degree of host specificity. The present study investigated sucking lice of the genus from six mouse lemur () and two dwarf lemur () species endemic to the island of Madagascar, considered a biodiversity hotspot. Louse phylogenetic trees were created based on cytochrome C oxidase subunit I (COI), elongation factor 1α (EF1α) and internal transcribed spacer 1 (ITS1) sequences.

Status of Infectious Diseases in Free-Ranging European Brown Hares () Found Dead between 2017 and 2020 in Schleswig-Holstein, Germany.

The European brown hare () is a quite adaptable species, but populations have been decreasing for several decades in different countries, including Germany. To investigate infectious diseases as possible influences on observed population decline in the German federal state Schleswig-Holstein, 118 deceased free-ranging European brown hares were collected between 2017 and 2020 and underwent detailed postmortem examination with extended sampling. Infectious diseases were a major cause of death (34.

Carriage of Extended Spectrum Beta Lactamase-Producing : Prevalence and Factors Associated with Fecal Colonization of Dogs from a Pet Clinic in Lower Saxony, Germany.

Extended spectrum beta-lactamase (ESBL)-producing are an emerging problem in veterinary and human medicine. Our study concentrated on the estimation of the prevalence and factors associated with the carriage of ESBL-producing in dogs who visited a veterinary clinic in northern Germany in 2017. For this reason, 1000 patients (healthy and sick dogs) were tested, resulting in 1000 samples originating from rectal swabs.

Year-round tick exposure of dogs and cats in Germany and Austria: results from a tick collection study.

Background: Ticks and tick-borne diseases play a major role in companion animal health. Additionally, the European tick fauna is changing, for instance due to the spread of Dermacentor reticulatus, displaying a higher likelihood of winter activity than Ixodes ricinus. Therefore, we investigated current tick infestations in dogs and cats in Germany and in parts of Austria and the seasonal infestation risk.

Understanding the uptake of diagnostics for sustainable gastrointestinal nematode control by European dairy cattle farmers: a multi-country cross-sectional study.

To mitigate emerging anthelmintic resistance (AR) in cattle, sustainable gastrointestinal nematode control strategies should be adopted. A multi-centre study was set up to understand the factors affecting European dairy cattle farmers' adoption of diagnostics and to gauge for differences between regions. The data were collected through a multi-lingual survey by participating countries of the European Co-operation in Science and Technology (COST) action COMbatting Anthelmintic Resistance in ruminants (COMBAR).

The prevalence and antibiotic susceptibility of spp. on ocular surfaces of fighting bulls () in Thailand.

Background And Aim: fighting bulls have a high risk of eye injuries, and opportunistic conjunctival bacterial flora may cause subsequent eye diseases. There is little information about the ocular health care of fighting bulls in Thailand. Thus, this study aimed to estimate the prevalence of spp.

in South American Camelids in Germany: First Insights into Molecular and Genetic Characteristics and Antimicrobial Resistance.

Little is known about zoonotic pathogens and their antimicrobial resistance in South American camelids (SAC) in Germany including (.) . The aim of this study was to investigate prevalence, molecular characteristics and antimicrobial resistance of in SAC.

Towards a Harmonized Terminology: A Glossary for Biocide Susceptibility Testing.

Disinfection is a key strategy to reduce the burden of infections. The contact of bacteria to biocides-the active substances of disinfectants-has been linked to bacterial adaptation and the development of antimicrobial resistance. Currently, there is no scientific consensus on whether the excessive use of biocides contributes to the emergence and spread of multidrug resistant bacteria.

Various mobile genetic elements carrying optrA in Enterococcus faecium and Enterococcus faecalis isolates from swine within the same farm.

Objectives: In this study, the distribution of the oxazolidinone/phenicol resistance gene optrA and the mobile genetic elements involved in its dissemination were analysed among enterococcal isolates from a farrow-to-finish swine farm.

Methods: Enterococcus faecium and Enterococcus faecalis isolates were obtained from all pig production stages in the farm. The optrA-carrying E.

Filarial infections in lemurs: Evidence for a wide geographical distribution and low host specificity among lemur species.

The relevance of emerging infectious diseases continues to grow worldwide as human activities increasingly extend into formerly remote natural areas. This is particularly noticeable on the island of Madagascar. As closest relatives to humans on the island, lemurs are of particular relevance as a potential origin of zoonotic pathogen spillover.

Cardio-pulmonary parasites of the European wildcat (Felis silvestris) in Germany.

Update and prognosis of distribution in Germany: Nationwide occurrence of .

A considerable range expansion of has been observed in several European countries, which is concerning in the light of its vector function for several pathogens, including and tick-borne encephalitis virus (TBEV). The present study provides an update on the distribution of ticks in Germany, using a citizen science approach. Ticks were collected by citizens from March 2020 to May 2021, and submitted along with information on the date and location of collection, potential hosts and details about the circumstances of discovery.

Modulation of the porcine intestinal microbiota in the course of Ascaris suum infection.

Background: The porcine roundworm Ascaris suum impairs feed conversion and weight gain, but its effects on intestinal microbiota remain largely unexplored.

Methods: Modulation of the intestinal microbiota was assessed in pigs that were infected once with 10,000 A. suum eggs and pigs that received a trickle infection (1000 eggs/day over 10 days), compared with a non-infected control group.

Evaluation of a commercial coproantigen immunoassay for the detection of Toxocara cati and Ancylostoma tubaeforme in cats and Uncinaria stenocephala in dogs.

Coproantigen immunoassays (IDEXX Fecal Dx® antigen tests) were evaluated for their ability to identify Toxocara cati and Ancylostoma tubaeforme infections in cats and Uncinaria stenocephala infection in dogs.
