Predicting the global potential distribution of two major vectors of Rocky Mountain Spotted Fever under conditions of global climate change
This study aims to explore the potential global suitability of areas for the vectors of Rocky Mountain spotted fever, includingDermacentor variabilis andAmblyomma cajennense under both historical and future climate scenarios. The study also seeks to investigate the impact of climatic factors on the distribution patterns of these vectors. Data on species distribution were downloaded from the Global Biodiversity Information Facility, Web of Science and PubMed database. The climatic variables were downloaded from WorldClim Global Climate Database. The Maximum Entropy Model was used to evaluate the contribution of monthly prec...

Case Report: Fatal Rickettsiosis in Pregnancy
We present a series of two cases of pregnant patients who showed up at the emergency room of a hospital in Nuevo León, Mexico. Both patients lived in environments where R. rickettsii is endemic and they presented with several days of symptoms, including fever. Both patients developed a rash and had stillbirths during their hospital stay. Treatment with doxycycline was delayed, with fatal results in both patients. Diagnosis of RMSF was confirmed via polymerase chain reaction assay postmortem. The need to link epidemiological clues with clinical data is critical in the diagnosis and early treatment of RMSF to prevent matern...

Evidence-practice gap analysis in the role of tick in brucellosis transmission: a scoping review
ConclusionsIt is imperative to improve the techniques used to identifyBrucella in ticks, particularly by developing a novel, efficient, precise approach that can be applied in a field setting. Furthermore, due to the lack of adequate evidence of tick-borne brucellosis, it is essential to integrate various disciplines, including experimental animal science, epidemiology, molecular genetics, and others, to better understand the efficacy of tick-borne brucellosis. By amalgamating multiple disciplines, we can enhance our comprehension and proficiency in tackling tick-borne brucellosis. (Source: Infectious Diseases of Poverty)

From the fat body to the hemolymph: Profiling tick immune and storage proteins through transcriptomics and proteomics
Insect Biochem Mol Biol. 2024 Jan 5:104072. doi: 10.1016/j.ibmb.2024.104072. Online ahead of print.ABSTRACTTicks are blood-feeding arachnids that are known to transmit various pathogenic microorganisms to their hosts. During blood feeding, ticks activate their metabolism and immune system to efficiently utilise nutrients from the host's blood and complete the feeding process. In contrast to insects, in which the fat body is known to be a central organ that controls essential metabolic processes and immune defence mechanisms, the function of the fat body in tick physiology is still relatively unexplored. To fill this gap, w...

Outcome and Sequelae of Infectious Encephalitis
J Clin Neurol. 2024 Jan;20(1):23-36. doi: 10.3988/jcn.2023.0240.ABSTRACTAcute infectious encephalitis is a widely studied clinical syndrome. Although identified almost 100 years ago, its immediate and delayed consequences are still neglected despite their high frequency and possible severity. We reviewed the available data on sequelae and persisting symptoms following infectious encephalitis with the aim of characterizing the clinical picture of these patients at months to years after hospitalization. We searched PubMed for case series involving sequelae after infectious encephalitis. We carried out a narrative review of t...

The potential for use of haematological and anti-IgE humoral responses as phenotypic markers for tick resistance in cattle
This study investigated the correlation between haematological cellular profiles and immunological responses (immunoglobulin E, IgE) and full body tick counts in herds of Bos indicus and Bos taurus following artificial tick challenge with Rhipicephalus decoloratus larvae. Fifty-four Friesian and Ayrshire (Bos taurus) and 52 East African Zebu (Bos indicus) calves were each infested with ∼2500 larvae. Near-replete adult female ticks (≥ 4.5 mm) were counted daily from Day 20-25. Blood and serum samples were obtained from each animal on Days 0 and 23 for cellular blood and IgE titre analysis, respectively. The indicine cat...
