is an ectoparasitic mite of Asian or Eastern honeybees which has become a serious threat to European subspecies of Western honeybees () within the last century. and its vectored honeybee viruses became serious threats for colony survival. This is a short period for pathogen- and host-populations to adapt. To look for possible variation in the composition of viral populations we performed RNA metagenomic analysis of the Western honeybee subspecies , , , and and their respective mites. The analysis revealed two novel viruses: Varroa orthomyxovirus-1 (VOV-1) in and and a Hubei like-virga virus-14 homolog in . VOV-1 was more prevalent in than in and we found evidence for viral replication in both hosts. Interestingly, we found differences in viral loads of and their , , and its showed partial similarity, while and and their varroa where very similar. Deformed wing virus exhibited 82.20%, 99.20%, 97.90%, and 0.76% of total viral reads in , , , and respectively. This is the first report of a complete segmented-single-stranded negative-sense RNA virus genome in honeybees and mites.

Epidemiological analysis and potential factors affecting the 2022-23 Crimean-Congo hemorrhagic fever outbreak in Iraq.
Eur J Public Health

Crimean-Congo hemorrhagic fever (CCHF) is an acute tick-borne disease with a case fatality rate of up to 40% in humans, posing a significant health threat. This study investigates the 2022-23 CCHF outbreaks in Iraq, the highest recorded to date, and analyzes potential factors at the human-animal-environmental interface. Data from the Iraqi government, the World Health Organization, and the World Bank were used to analyze CCHF trends and affecting factors.

Purpose: Tick diversity in Algeria has garnered increasing interest due to its implications for animal health and zoonotic diseases. Recent reports of abnormal ulcerative lesions in goats and sheep in the Cheria region of northeastern Algeria have raised concerns about a potential association with tick infestations. The aim of this study is to hypothesize the potential involvement of ticks in these unusual lesions.

The research aimed to investigate the perinatal pathology of Alpine ibex () through the study of four young subjects (at the age of 3 to 4 months) found dead in Valle d'Aosta, a region of northwestern Italy. The carcasses were submitted to necropsy followed by an examination of ecto- and endoparasites (ECP and ENP); samples from the gross lesions (in summary, cutaneous papilloma and crusts, ocular discharge, lobular haemorrhagic areas in the lungs, catarrhal-haemorrhagic enterocolitis) were analysed by bacteriological, histopathological, and biomolecular methods to define the etiological agent. The subjects, with various co-infection patterns, were affected by contagious ecthyma virus (ORFV) (agent of a highly diffusive pustular dermatitis transmissible to small ruminants and humans), Enteropathogenic (EPEC) (major etiological agent of infantile diarrhoea especially in developing countries), (MC) (cause of an ocular infection common to goats and sheep), various ECP (ticks and keds) and ENP (lung and intestinal nematodes, and coccidia).

Purpose Of Review: Several microorganisms, which are not traditionally considered sexually transmitted infections (STIs), are capable of sexual transmission and have the potential to cause global outbreaks. The aim of this review is to describe pathogens which are not traditionally defined as STIs, to grant insight on current and potential outbreaks and call for clinical vigilance among members of key populations.
Recent Findings: Recent findings emphasize that several pathogens, not traditionally classified as STIs, can be sexually transmissible.

Article Synopsis
- * In 2021, researchers analyzed RNA viromes from a significant number of honey bees and mites, uncovering 45 complete and 1702 partial viral genomes, leading to the identification of new viral entities.
- * Common viruses identified included Sinaivirus and various strains of Iflavirus, with concerns that existing detection methods might misrepresent the presence of certain virus types in honey bee populations.
