Paratuberculosis in South American camelids: two independent cases in alpacas in Germany.

Background: Paratuberculosis, caused by Mycobacterium avium subspecies paratuberculosis (MAP), is a chronic granulomatous enteritis that affects domestic and wild ruminants and camelids. The disease has rarely been reported in alpacas in Germany. This publication describes epidemiologically independent cases of paratuberculosis in two alpacas in Germany.

Experimental arboviral infection of mosquito larvae: A novel approach for vector competence studies.

Vector competence studies in mosquitoes present valuable opportunities to explore arboviral transmission and virus-vector interactions. However, oral infection studies in mosquitoes can be challenging. An alternative approach is to infect mosquitoes during their aquatic larval stage, resulting in the emergence of infected adults.

Intratesticular versus intraperitoneal Busulfan administration: a comparative study on spermatogenesis suppression in quails and chickens.

Generation of transgenic birds can be achieved by temporal suppression of endogenous spermatogenesis in males prior to primordial germ cell implantation. One of many established methods to induce male sterility is the intraperitoneal injection of busulfan, an alkylating agent. Nevertheless, the use of busulfan injections, which may also affect hematopoietic stem cells, carries the risk of potential lethality in animals.

Antibacterial Activity of Microbial Natural Products against Bacterial Pathogens of Veterinary and Zoonotic Relevance.

Antimicrobial resistance (AMR) is considered one of the greatest threats to both human and animal health. Efforts to address AMR include implementing antimicrobial stewardship programs and introducing alternative treatment options. Nevertheless, effective treatment of infectious diseases caused by bacteria will still require the identification and development of new antimicrobial agents.

Pathomorphological Findings and Infectious Diseases in Selected European Brown Hare () Populations from Schleswig-Holstein, Germany.

In the northernmost German federal state Schleswig-Holstein, populations of European brown hares () show diverse densities and varying courses over the years. To examine differences in pathomorphological findings and infectious diseases as possible reasons for varying population dynamics, we assessed 155 hunted hares from three locations in Schleswig-Holstein from 2016 to 2020. We investigated the association of location, year, age, and sex of animals to certain pathomorphological findings and infectious diseases.

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.

A one health glossary to support communication and information exchange between the human health, animal health and food safety sectors.

Collaboration across sectors, disciplines and countries is a key concept to achieve the overarching One Health (OH) objective for better human, animal and environmental health. Differences in terminology and interpretation of terms are still a significant hurdle for cross-sectoral information exchange and collaboration within the area of OH including One Health Surveillance (OHS). The development of the here described glossary is a collaborative effort of three projects funded within the One Health European Joint Programme (OHEJP).
