Epidemiological factors associated with the distribution of Rickettsia hosts in Ucú, Yucatan, Mexico

Tropical and Subtropical Agroecosystems
Background. Rickettsioses are zoonoses caused by pathogenic bacteria of the genus Rickettsia transmitted through bites or feces of ectoparasites (ticks, fleas, lice, and hematophagous mites). Rodents and dogs play a role in the transmission of pathogenic

Short Report: First Outbreak of Atlantic Rainforest Spotted Fever in North‐Eastern of Brazil—Clinical Features and Eco‐Epidemiological Investigation

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Since 2010, six cases of Atlantic rainforest spotted fever (ARSF) have been confirmed and reported in Brazil, a tick‐borne disease caused by Rickettsia parkeri strain Atlantic rainforest and associated with the tick Amblyomma ovale. So far, none of the cases have been associated with death. One of the cases occurred in 2018 in the

Minor Risk to Contract Metazoan Parasites via the Consumption of Edible Snails, Born and Reared in France

Zoonoses and Public Health, EarlyView.
ABSTRACT In a context of food security of animal consumption and diversification of protein sources, we have studied the risks to contract metazoan parasites through the consumption of ‘gros‐gris’ snails (Cornu aspersum maximum) sampled in 12 French farms.

Rickettsia parkeri in Gulf Coast Ticks, Southeastern Virginia, USA

Emerging Infectious Diseases, 2011
We report evidence that Amblyomma maculatum tick populations are well established in southeastern Virginia. We found that 43.1% of the adult Gulf Coast ticks collected in the summer of 2010 carried Rickettsia parkeri, suggesting that persons living in or

Clinical Laboratory Innovations: Nanoscale Detection of Chloramphenicol Using Nanomaterial Biosensors

Analytical Science Advances, Volume 7, Issue 2, December 2026.
Nanosensor schematic functionalized with specific bioreceptors that produce electrochemical signals upon Chloramphenicol binding. Resulting voltammetric readouts (differential pulse, square‐wave, and cyclic voltammetry) are analyzed to identify and quantify Chloramphenicol.

Rickettsial Illnesses as Important Causes of Febrile Illness in Chittagong, Bangladesh

Emerging Infectious Diseases, 2018
We conducted a yearlong prospective study of febrile patients admitted to a tertiary referral hospital in Chittagong, Bangladesh, to assess the proportion of patients with rickettsial illnesses and identify the causative pathogens, strain genotypes, and ...

DEET‐cyclodextrin inclusion complexes for mosquito and tick repellency: Extended repellency time and no zebrafish embryotoxicity

Pest Management Science, Volume 82, Issue 10, Page 9653-9665, October 2026.
Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

Rickettsia

REMUS - Revista Estudiantil de Medicina de la Universidad de Sonora
La FMMR es una enfermedad letal de rápida progresión que requiere diagnóstico clínico, dado que la mayoría de los resultados diagnósticos no están disponibles de manera oportuna. El tratamiento temprano de manera empírica es crucial para reducir la mortalidad.

Comparative study of mtDNA in species of the genus Adalia (Coleoptera: Cocinellidae) and origin of ancient mitochondrial haplotypes in the gene pool of Adalia bipunctata

European Journal of Entomology, 2013
Fifteen different mitochondrial haplotypes of the mtDNA gene COI encoding cytochrome C oxidase subunit I were identified in the 127 individuals of Adalia bipunctata studied. Two mitochondrial haplotypes, H9 and H10, differed greatly from the others.
