Age‐Related and Seasonal Variation in Malaria and Other Causes of Fever and Their Association With Clinical Outcomes in Southern Angola: A Hospital‐Based Study

Tropical Medicine &International Health, Volume 31, Issue 9, Page 1273-1283, September 2026.
ABSTRACT Background Acute febrile illnesses in sub‐Saharan Africa are often attributed to malaria, yet many patients test negative for malaria parasites. The aetiology of nonmalarial fevers remains understudied. Here, we examine likely causes of febrile illnesses and their association with poor clinical outcomes in Angola.

Spotted fever group rickettsia in small rodents from areas of low endemicity for brazilian spotted fever in the eastern region of Minas Gerais state, Brazil.

, 2013
We investigated the humoral immune response against different species of Rickettsia in serum samples from small rodents collected in two areas of a silent focus for Brazilian spotted fever in the eastern region of Minas Gerais State, Brazil.

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

Biological Reviews, Volume 101, Issue 4, Page 1779-1792, August 2026.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

Journal of Applied Entomology, Volume 150, Issue 7, Page 990-1015, August 2026.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Ultrastructural Study on Japanese Isolates of Spotted Fever Group Rickettsiae [PDF]

Microbiology and Immunology, 1988
AbstractJapanese isolates of spotted fever group rickettsiae were observed under a transmission electron microscope. In Vero cells persistently infected with Japanese isolates, small numbers of intracytoplasmic rickettsiae were seen. On the other hand, moderate numbers of rickettsiae were found in the cytoplasm of productively infected BHK cells.

Korat‐Scrub Typhus Score: A Clinical Tool for Predicting Scrub Typhus in Patients With Acute Undifferentiated Febrile Illness

Tropical Medicine &International Health, Volume 31, Issue 8, Page 1066-1072, August 2026.
ABSTRACT Objective Scrub typhus is a major cause of acute undifferentiated febrile illness (AUFI) in the Asia–Pacific region. Nonspecific presentation, limited diagnostic accuracy and delayed treatment increase morbidity and mortality. This study aimed to develop a simple clinical score for early diagnosis in adults with AUFI. Methods A cross‐sectional
