ConclusionsOrganisms that are easier to treat and more difficult to spread, such as scabies or lice, can contribute substantially to nursing workload. Notably, three-quarters of the nurses and one-half of the IPs reported that C difficile adds>1 hour to their daily workload.

Purpose: On 29 May 2018, the Austrian Agency of Health (AGES) was contacted by the head of a home for assisted living, which had 11 residents. She reported significant pest infestation, occurrence of vermin for three days throughout the whole facility. Vermin extermination (gassing by a professional) had no effect: vermin were still present on the residents in their groins, navels, and armpits and the pests still continued to multiply “by leaps and bounds, traveling throughout the house”. Residents suffered from “red skin rashes” and ambulance drivers refused to take the vermin infested patients to hospital.

Abstract Marine ecosystems are beset by disease outbreaks, and efficient strategies to control dispersal of pathogens are scarce. We tested whether introducing no-farming areas or 'firebreaks' could disconnect dispersal networks of a parasitic disease affecting the world's largest marine fish farming industry (∼1000 farms). Larval salmon lice (Lepeophtheirus salmonis) are released from and transported among salmon farms by ocean currents, creating inter-farm networks of louse dispersal. We used a state-of-the-art biophysical model to predict louse movement along the Norwegian coastline and network analysis to ...

Drones transporting sterilized male mosquitos, cybernetic dragonflies, genetically modified insects with malaria-resisting traits, supersensitive radars or digital maps: the most innovative methods are deployed in the war on the tiniest but most murderous beasts out there: mosquitos, fleas, ticks carrying infectious diseases. Here’s the latest arsenal of digital technologies to eradicate insects and reduce deadly epidemics. Unusual suspects: mosquitos, fleas, and ticks Sharks, bears, tigers, the Killer Rabbit of Caerbannog in association with sharp teeth and claws represent the traditional image of deadly animals. Ho...

Rickettsial infections are caused by bacteria from the Rickettsia genus which are often spread by biting ticks, fleas, mites or lice. Rickettsia can cause mild to severe illness and Rickettsia species can be found worldwide. Early stage, nonspecific symptoms of infections can make clinical diagnosis difficult. Rickettsial infection symptoms, if present, typically develop within 1 -2 weeks of exposure and include fever, headache, malaise, rash, nausea, and vomiting. Some rickettsial diseases such as Rocky Mountain spotted fever (RMSF), Mediterranean spotted fever, and typhus fever, can be life threatening and even fatal in ...

One of the worst pandemics in human history, the Black Death, along with a string of plague outbreaks that occurred during the 14th to 19th centuries, was spread by human fleas and body lice, a new study suggests.

In this study, the brown dog tick Rhipicephalus sanguineus sensu lato, cat louse Felicola subrostratus, and cat fleas Ctenocephalides felis and Ctenocephalides orientis collected from free-ranging cats and dogs in Malaysia were molecularly screened for the presence of Bartonella and Rickettsia bacteria, and Dipylidium tapeworm. Our results showed the presence of Bartonella clarridgeiea, Bartonella henselae (lineage Marseille and lineage Houston-1), and Rickettsia sp. in C. felis. We also detected Rickettsia asembonensis in C. orientis and R. sanguineus s.l. Additionally, this study provides the first documentation on a pot...

In conclusion, this study demonstrated the occurrence of SFG rickettsiae in domestic, synanthropic and wild animals, and suggests the use of equines and canines as good sentinels of infection, in the study zone. We speculate that exist a transmission cycle that involves rodents in the areas where these outbreaks have occurred. Tomes' spiny rats (Proechimys semispinosus) and common opossums (Didelphis marsupialis) could be good candidates as amplifier hosts for SFG rickettsiae in enzootic/endemic zones.

Oppedal Diverse chemical-free parasite controls are gaining status in Atlantic salmon sea-cage farming. Yet, the intricacies of their use at commercial scale, including effects on co-occurring parasites, are seldom reported. A new salmon lice prevention method involves installing a deep net roof and ‘snorkel’ lice barrier in cages to shelter salmon from free-living infective larvae which concentrate at shallow depths, and allows salmon...

There is perhaps nothing more fear-inducing for parents than receiving the dreaded “LICE” note from their kid’s school. These notorious outbreaks have the power to make even the most level-headed parents want to burn all of their belongings and shave every family member’s head. Many moms and dads vent about their head lice anxieties on Twitter, and some manage to find humor in the bleakness. We’ve rounded up 47 tweets about the nightmare that is a lice outbreak. Try not to scratch your head while reading. Lice is the herpes of kindergarten.— Wonder Kitten (@Tw1tter_K1tten) December 31, ...
