This study assessed the prevalence of B. burgdorferi s. l. among four non-Peromyscus rodents in a prairie ecosystem in the Midwestern United States over a four-year period. We found high prevalences of the bacteria in all four species studied. Our results help to support the roles of Microtus species as reservoirs of B. burgdorferi and add to the literature that suggests Zapus hudsonius may also be a reservoir. Additionally, we identified a previously unknown possible reservoir, Ictidomys tridecemlineatus. Our study also identifies the need to study the dynamics of Lyme borreliosis in habitats and areas outside of the typi...

AbstractPurpose of ReviewTicks are the most important vectors of human diseases after mosquitoes. Emergency physicians throughout the USA can be expected to encounter Lyme disease, Rocky Mountain spotted fever, ehrlichiosis, and other disorders based upon geographic location.Recent FindingsThe number of identifiable disorders transmitted by these arthropods has increased in recent years. Severe fever with thrombocytopenia syndrome has only been described within the past decade, and the new millennium has seen over 10 new species of rickettsial disease discovered.SummaryTicks transmit more pathogenic species than any other ...

Publication date: Available online 11 June 2019Source: Ticks and Tick-borne DiseasesAuthor(s): Kalvis Brangulis, Inara Akopjana, Ivars Petrovskis, Andris Kazaks, Kaspars TarsAbstractThe spirochete Borrelia burgdorferi sensu lato is the causative agent of Lyme borreliosis – the most common tick-borne disease in Europe and the United States. Spirochetes are transmitted from infected Ixodes ticks to the mammalian host when the ticks feed. In general, the transfer process of the borreliae is quite complicated, as the environments in the tick and the new mammalian host differs significantly. Therefore, Borrelia changes th...

The tick that carries Lyme can also transmit the rare but serious powassan virus believed to have killed one man and sickened another in New Jersey

There are new concerns about previously-rare types of tick-borne diseases being seen more frequently in the United States. The blacklegged tick not only spreads Lyme disease, it can also transmit a serious virus that may have killed one man and made another sick in New Jersey. In Kentucky, a two-year-old boy is reportedly recovering from another tick-borne disease, Rocky Mountain spotted fever. Dr. David Agus joins "CBS This Morning" from Los Angeles to discuss how to protect yourself from ticks, how to remove them and the consequences of some tick-borne diseases.

Publication date: Available online 8 June 2019Source: Ticks and Tick-borne DiseasesAuthor(s): Amira Nebbak, Handi Dahmana, Lionel Almeras, Didier Raoult, Nathalie Boulanger, Benoit Jaulhac, Oleg Mediannikov, Philippe ParolaAbstractFifty nymphal Ixodes ricinus ticks collected in Alsace, France, identified by morphological criteria and using MALDI-TOF MS, were tested by PCR to detect tick-associated bacteria and protozoan parasites. Seventy percent (35/50) of ticks contained at least one microorganism; 26% (9/35) contained two or more species. Several human pathogens were identified including Borrelia burgdorferi s.s. (4%), ...

In this study, we identify an Ixodes scapularis salivary gland protein, Salp12, that is a chemoattractant for the spirochete. We demonstrate that Salp12 is expressed in the I. scapularis salivary glands and midgut and expression is not impacted by B. burgdorferi s.s. infection. Knockdown of Salp12 in the salivary glands or passive immunization against Salp12 reduces acquisition of the spirochete by ticks but acquisition is not completely prevented. Knockdown does not impact transmission of B. burgdorferi s.s. This work suggests a new role for chemotaxis in acquisition of the spirochete and suggests that recognition of Salp...

BOSTON (CBS) — Looking back at baby pictures reminds Brandi Dean of a terrifying scare during her second pregnancy. It turns out the Wellesley mom had Lyme disease. “All of a sudden, the right side of my body was completely numb. My heart was racing. I was disoriented and I said, ‘I think you need to take me to the hospital,’” she remembered. After the standard antibiotic treatment, Dean still didn’t feel right. “I’d gone to 12 different specialists and they all had diagnosed me with anxiety.” She had what the Centers for Disease Control calls Post-Treatment Lyme Syndro...

oor Ticks are vectors of several pathogens that can be transmitted to humans and their geographic ranges are expanding. The exposure of ticks to new hosts in a rapidly changing environment is likely to further increase the prevalence and diversity of tick-borne diseases. Although ticks are known to transmit bacteria and viruses, most studies of tick-borne disease have focused upon Lyme disease, which is caused by infection with Borrelia burgdorferi. Until recently, ticks were considered as the vectors of a few viruses that can infect humans and animals, such as Powassan, Tick-Borne Encephalitis and Crimean–Co...
