The First Report on Cat Flea (Ctenocephalides felis), a Zoonotic Haematophagous Insect Infestation in Humans in Bangladesh: A Case Report and Literature Review

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
An 18‐year‐old girl who didn't have any pets but was infested with fleas from a pet‐owning neighbour. Flea‐bite dermatitis caused severe pruritus, urticarial and papulomatous lesions on the neck and arm. Fleas were removed and identified as Ctenocephalides felis, the cat flea.

Prevalence and risk factors for murine typhus, scrub typhus and spotted fever group rickettsioses among adolescent and adult patients presenting to Yangon General Hospital, Yangon, Myanmar

Tropical Medicine &International Health, Volume 30, Issue 9, Page 966-977, September 2025.
Abstract Objectives To inform patient management and disease prevention, we sought to estimate the prevalence of, and identify risk factors for, scrub typhus, murine typhus, and spotted fever group rickettsioses (SFGR) among febrile patients presenting to hospital in Myanmar.

Estimating scrub typhus and murine typhus incidence among adolescents and adults in Yangon, Myanmar

Tropical Medicine &International Health, Volume 30, Issue 9, Page 978-986, September 2025.
Abstract Objectives Rickettsioses are frequent causes of treatable febrile illness in Southeast Asia, including Myanmar. Accurate estimates of the incidence of rickettsioses are needed to inform investments in disease prevention and control. We sought to estimate the incidence of rickettsioses among adults and adolescents by combining sentinel hospital

Investigation of Anti‐IgG Antibody Responses to the 17‐kDa Outer Membrane Protein of Rickettsia japonica in Individuals From a High‐Risk Area for Japanese Spotted Fever

Experimental Dermatology, Volume 34, Issue 7, July 2025.
ABSTRACT This study evaluated the seroprevalence and persistence of IgG antibodies against Rickettsia japonica's outer membrane protein (Omp) using a recombinant 17‐kDa antigen and Western blot analysis in residents of Minamiise, Japan—a high‐incidence Japanese spotted fever (JSF) area—and in individuals from non‐endemic regions.

Development of Antisense Tools to Study Bodo saltans and Its Intracellular Symbiont

MicrobiologyOpen, Volume 14, Issue 2, April 2025.
Obligate symbioses present challenges for functional genetic analysis. This study shows that antisense inhibition cannot be used to investigate gene functions in the aquatic symbiosis between Bodo saltans and its bacterial symbiont. Our work stresses the importance of the development of alternative protocols to study the biology of both the ...

Prolonged Fever in Children: An Inpatient Diagnostic Framework for Infections in Australia

Journal of Paediatrics and Child Health, Volume 61, Issue 4, Page 532-539, April 2025.
ABSTRACT There are many causes of fever in children, ranging from common and self‐limiting to serious and life threatening. Careful assessment of children with prolonged fever without an obvious or identified source requires detailed history and examination with consideration of infections unique to the specific geographical region and individual ...
