Rocky Mountain Spotted Fever, Panama
Emerging Infectious Diseases, 2007 We describe a fatal pediatric case of Rocky Mountain spotted fever in Panama, the first, to our knowledge, since the 1950s. Diagnosis was established by immunohistochemistry, PCR, and isolation of Rickettsia rickettsii from postmortem tissues.

Immunological Reviews, Volume 332, Issue 1, July 2025.ABSTRACT The primary features of the alpha‐gal syndrome (AGS) are (i) The IgE ab that are causally related to anaphylaxis with infusions of Cetuximab are specific for galactose alpha‐1,3‐galactose. (ii) In the USA, this IgE ab is induced by bites of the tick Amblyomma americanum. (iii) The anaphylactic reactions to food derived from non‐primate mammals

Legionella pneumophila modulates the host cytoskeleton by an effector of transglutaminase activity
mLife, Volume 4, Issue 3, Page 232-248, June 2025.Abstract The bacterial pathogen Legionella pneumophila delivers more than 330 effector proteins into host cells through its Dot/Icm type IV secretion system (T4SS) to facilitate its intracellular replication. A number of these effectors modulate organelle trafficking pathways to create a membrane‐bound niche called the Legionella‐containing vacuole ...

In vitro guinea pig leukocyte reactions to Rickettsia rickettsii [PDF]
Infection and Immunity, 1977 The presence of cell-mediated immunity in Rocky Mountain spotted fever-infected guinea pigs was determined by two in vitro assays: whole blood lymphocyte transformation (LT) and macrophage migration inhibition. Increased LT was detected as early as 1 week in guinea pigs infected with Rickettsia rickettsii and treated with oxytetracycline and was ...

Curvature and torsion in growing actin networks
, 2007 Intracellular pathogens such as Listeria monocytogenes and Rickettsia rickettsii move within a host cell by polymerizing a comet-tail of actin fibers that ultimately pushes the cell forward.

Development of a duplex real-time PCR for the detection of Rickettsia spp. and typhus group rickettsia in clinical samples. [PDF]
, 2011 Molecular diagnosis using real-time polymerase chain reaction (PCR) may allow earlier diagnosis of rickettsiosis. We developed a duplex real-time PCR that amplifies (1) DNA of any rickettsial species and (2) DNA of both typhus group rickettsia, that is ...

Sufficient reproduction numbers to prevent recurrent epidemics
Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1186-1200, June 2025.Abstract Current practice in the design and evaluation of control measures in disease ecology and epidemiology, including vaccination, is largely based on reproduction numbers (RNs), which represent prognostic indices of long‐term disease transmission, both in naïve populations (basic RN) and in the presence of prior exposure or infection containment ...
