Emerging infectious diseases

2006 6 citations

Advanced Summarizations Available

This study detected the presence of Ehrlichia ruminantium, the causative agent of heartwater, in Amblyomma variegatum and Amblyomma lepidum ticks in Sudan. The researchers also identified a new strain of E. ruminantium, named Gedaref, in A. lepidum ticks.

Vector borne and zoonotic diseases (Larchmont, N.Y.)

2012 10 citations

Rickettsia slovaca, the cause of tick-borne lymphadenopathy (TIBOLA), was identified in a goat blood sample for the first time. This discovery suggests that domestic ruminants, including sheep, goats, and bullfighting cattle, are exposed to R. slovaca infection. The close proximity of this domestic cycle to human environments may increase the risk of transmitting the pathogen to humans.

2016 3 citations

Babesia microti, a protozoan parasite associated with small mammals and Ixodes ticks, was examined for its prevalence in an area with Ixodes persulcatus and Ixodes trianguliceps. The study found B. microti DNA in 31.6% of samples from small mammals, with two genetic groups: enzootic 'Munich' type and zoonotic 'US' type. However, no B. microti was found in Ixodes ticks. The research suggests that the high prevalence of B. microti 'Munich' type in small mammals may be due to its prolonged persistence in their blood.

Advanced Summarizations Available

The study found that miniature pinscher dogs, known to be tick-resistant, produce certain semiochemicals that repel the brown dog tick. Two of these compounds, 2-hexanone and benzaldehyde, were present in all three breeds tested (beagle, miniature pinscher, and English cocker spaniel). However, two other compounds, 6-methyl-5-hepten-2-one and 1,2,4-trimethylbenzene, were found in higher amounts in samples from miniature pinschers. Particularly, 6-methyl-5-hepten-2-one showed repellent properties against the brown dog tick, suggesting its potential for development as a repellent for dogs.

Molecular survey of Coxiella burnetii in veterinary sample and ticks in Malaysia / Meeta Devi Nurkunasegran

2017

This study, conducted in Malaysia, uses molecular methods to detect the presence of Coxiella burnetii, the causative agent of Q fever, in veterinary samples and ticks. The research found C. burnetii DNA in milk, vaginal swabs, blood samples from domestic livestock, and in tick species such as Amblyomma spp., Dermacentor spp., Rhipicephalus spp. and Haemaphysalis spp. The study suggests that the transposon-like gene IS1111 assay is more sensitive in detecting C. burnetii DNA, and awareness for prevention and control of Q fever transmission is necessary.

Silva-Ramos Carlos Ramiro, Hidalgo Marylin, Faccini-Martínez Álvaro A.

Ticks and tick-borne diseases

America, East Coast, United States, Argentine Republic, Federative Republic of Brazil, Oriental Republic of Uruguay, Republic of Colombia

2021

Rickettsia parkeri rickettsiosis, the second most prevalent tick-borne disease in the Americas, has been studied in a systematic review. The research includes 77 clinical cases, both confirmed and probable, transmitted by Amblyomma spp. ticks. The study finds that males aged 18-64 are more frequently affected, with symptoms like fever, eschar, rash, headache, and myalgia. At least 60% of the cases showed altered laboratory parameters, primarily increased transaminases and leukopenia. Tetracyclines were the primary antibiotics used, leading to a 100% clinical recovery rate.

BMJ case reports

Wood County, Southampton

2009

A 46-year-old man discovered a tick burrowed in his genital area after walking in Hutt Wood, Southampton. The tick was identified as a wood tick (Dermacentor variabilis) and was removed. The text discusses the ineffectiveness of Vaseline and dressings, and potential harm of caustic applications for tick removal.

What makes ticks tick? Climate change, ticks, and tick-borne diseases

Süss Jochen, Klaus Christine, Gerstengarbe Friedrich‐Wilhelm, Werner Peter C.

Journal of travel medicine

2008 59 citations

Tick-borne diseases, specifically TBE and Lyme Borreliosis, have been increasingly prevalent in Europe and other regions over the past decades. Ixodes ricinus (and persulcatus in Eastern Europe) are responsible for 90% to 95% of tick bite incidents in humans, leading to approximately 100,000 to 150,000 cases of LB and 10,000 to 15,000 cases of TBE annually. Climate change has been identified as a significant factor contributing to the rise of these diseases; however, agricultural production, leisure activities, and travel also play a role.

Biological Rhythm Research

2018 8 citations

The study conducted in West Bengal from July 2015 to June 2016 found that 41.93% of examined cattle were infested with hard ticks, predominantly Rhipicephalus (Boophilus) sp., Hyalomma sp., and Haemaphysalis sp. The prevalence was higher in female cattle, the youngest (<1 year) and oldest (>3 years) age groups, and during the monsoon season. The study suggests these findings could aid in developing effective tick control strategies for bovines in the region.

Detection of Rickettsia spp. in Rhipicephalus sanguineus (sensu lato) collected from free-roaming dogs in Coahuila state, northern Mexico

Parasites & vectors

2019 1 citations

Advanced Summarizations Available

This study detected and molecularly identified Rickettsia spp. in Rhipicephalus sanguineus (sensu lato) collected from free-roaming dogs in Coahuila State, Mexico. The results confirmed the presence of R. rickettsii and R. rhipicephali in R. sanguineus (s.l.) ticks. This suggests that stray dogs may play a role in the inter-municipal dissemination of infected ticks in this region.

Molecular Detection of Francisella spp. Among Ticks Attached to Camels in Egypt

Vector borne and zoonotic diseases (Larchmont, N.Y.)

2017 7 citations

This study investigates the role of camels and ticks in the epidemiology of Francisella spp., including Francisella tularensis. Of the 319 ticks examined, 15 were positive for Francisella spp., all from Hyalomma dromedarii. However, none of the blood or fecal samples from camels were positive, nor was F. tularensis detected in the tick samples. Phylogenetic analysis suggests these are related to Francisella-like endosymbionts. Seroprevalence of F. tularensis antibodies among examined abattoir workers was 9.3%, significantly higher in those frequently exposed to tick bites, indicating a potential role of ticks in transmitting tularemia to humans.

Tick ecology

International journal for parasitology

1994

The text discusses the integration of ecological principles into tick control methods, which was initially driven by the development of acaricides and vaccination procedures. Further research on tick life processes, their interaction with hosts and the environment, has led to the use of producer manipulation of acaricide application frequencies, habitat manipulation techniques, and host immunity in tick control.

Paralysis by Ticks

Clinical Infectious Diseases

1993 2 citations

Ticks, particularly the paralysis tick, are a serious parasite in Eastern Australia, causing toxicosis that affects both animals and humans. They are native to Australia and primarily infest marsupials, but also impact livestock and domestic pets. The identification of ticks is crucial to determine necessary treatment.

This research study, conducted in Sardinia island, investigates the presence and diversity of piroplasmids in ticks collected from domestic and wild hosts. The findings reveal the presence of various strains related to the Theileria buffeli/sergentii/orientalis complex and other tick-borne diseases such as equine piroplasmosis, ovine theileriosis, and bovine babesiosis in different tick species. This study contributes to the understanding of tick-borne pathogens in the Mediterranean region.
