Falciparum Malaria Outbreak in Sabah Linked to an Immigrant Rubber Tapper.
In conclusion, an outbreak of P. falciparum malaria was introduced into a malaria-free village by a migrant rubber tapper, by whom the imported parasite was introduced to the community via vector Anopheles balabacensis. Living near stagnant water bodies was the risk factor in this outbreak. PMID: 29141714 [PubMed - as supplied by publisher]

Temporal distribution of, and effect of anthropic modifications on, phlebotomine populations in the Chaco Bioregion, Argentina
Abstract The Phlebotominae (Diptera: Psychodidae) are insects of medical and veterinary importance, because some species are able to transmit pathogens such as Leishmania spp. In the last 20 years, numerous leishmaniasis outbreaks have been reported in the Chaco Bioregion (Argentina), with an increasing trend of cases associated with periurban transmission. The Chaco Bioregion has two sub‐regions according to their climatic and ecological characteristics: the Dry Chaco and the Humid Chaco. In the present study, sandfly captures were performed in both sub‐regions, at sites with different levels of anthropic modificati...

A distinct group of north European Aedes vexans as determined by mitochondrial and nuclear markers
Abstract The floodwater mosquito Aedes (Aedimorphus) vexans (Meigen, 1830) (Diptera: Culicidae) is common in several areas of Sweden and is predicted to become more abundant in the wake of expected changes in precipitation and temperature caused by climate change. As well as being a nuisance, Ae. vexans can act as a vector of over 30 viruses. In the event of an outbreak of disease caused by a vector‐borne virus, knowledge of the distribution, population structure and intermixing of populations from different locations will help direct resources to target locations to prevent spread of the pathogen. The present study ana...

The prevalence and distribution of sheep scab in Wales: a farmer questionnaire survey
Abstract Outbreaks of ovine psoroptic mange in the U.K. have increased 100‐fold since its deregulation in 1992, with the highest prevalence in Wales, a region of high sheep density. A cross‐sectional, retrospective, questionnaire‐based survey of 7500 members of the association of Welsh lamb and beef farmers [Welsh Lamb and Beef Producers Ltd (WLBP)] was used to investigate the prevalence and distribution of sheep scab in this region in 2015. The survey was completed by 14.0% (n = 972) of potential respondents. Scab outbreaks were reported on 15.8% (n = 154) of farms in 2015. However, 29.0% (n = 282) of fa...

A review and illustrated description of Musca crassirostris, one of the most neglected haematophagous livestock flies
Musca crassirostris belongs to a group of true obligate blood feeders that are highly prolific and abundant around cattle. Its mentum is a boat ‐shaped, black, shiny mass of chitin, and its labella harbours rasping prestomal teeth that are greatly increased in size and strength compared with those in otherMusca spp. Based on captures in haematophagous insect traps in a livestock area, the abundance ofM. crassirostris appears to be four and 45 times greater than abundances of stomoxyines and tabanids, respectively. AbstractTabanids, stomoxyine flies, hippoboscids and tsetse flies are the most well ‐known brachyceran bit...

Amino Acid Utilization May Explain Why Bemisia tabaci Q and B Differ in Their Performance on Plants Infected by the Tomato yellow leaf curl virus
Discussion Research has shown that vectored viruses can alter host plant phenotypes so as to change interactions with other organisms, including interactions between plants, viruses, and insect vectors of viruses (Mauck et al., 2012, 2018; Casteel and Falk, 2016; Eigenbrode and Bosque-Perez, 2016; Mauck, 2016). Insect-vectored viruses can alter many host plant factors, including odors, induced defenses, visual and tactile characteristics, sugars, free amino acids, and secondary metabolites (Bosque-Perez and Eigenbrode, 2011; Casteel et al., 2014; Mauck et al., 2014a,b). In our study, TYLCV significantly altered the free a...

Signalling and responding to zoonotic threats using a One Health approach: a decade of the Zoonoses Structure in the Netherlands, 2011 to 2021
In the Netherlands, the avian influenza outbreak in poultry in 2003 and the Q fever outbreak in dairy goats between 2007 and 2010 had severe consequences for public health. These outbreaks led to the establishment of an integrated human-veterinary risk analysis system for zoonoses, the Zoonoses Structure. The aim of the Zoonoses Structure is to signal, assess and control emerging zoonoses that may pose a risk to animal and/or human health in an integrated One Health approach. The Signalling Forum Zoonoses (SO-Z), the first step of the Zoonoses Structure, is a multidisciplinary committee composed of experts from the medical...

News at a glance: ‘Cherry-picked’ vaccine guidance, AI-written papers, and an apology for prisoner research
ENVIRONMENT Utah’s Great Salt Lake may dry up within 5 years North America’s largest saline lake could be gone by 2028 if water inflows are not restored, researchers warned last week. The Great Salt Lake in Utah has lost nearly three-quarters of its water and 60% of its surface area since 1950, a report from 32 scientists at multiple institutions concludes, and a recent drought has accelerated the losses. To restore the lake, farmers, homeowners, and others will need to reduce the amount of water they take from feeder streams by 30% to 50% . If they don’t, the continent could lose a key habitat ...
