The Wolbachia Genome of Brugia malayi: Endosymbiont Evolution within a Human Pathogenic Nematode [PDF]

open access: yes, 2005
Complete genome DNA sequence and analysis is presented for Wolbachia, the obligate alpha-proteobacterial endosymbiont required for fertility and survival of the human filarial parasitic nematode Brugia malayi. Although, quantitatively, the genome is even

Geographic Variation in the Prevalence of Candidatus Neoehrlichia procyonis in Raccoons (Procyon lotor) in the United States and Canada

open access: yesMicrobiologyOpen, Volume 14, Issue 1, February 2025.
A total of 167/394 (42.4%) raccoons were positive for Candidatus Neoehrlichia procyonis. Spatial variation was noted with higher prevalences in the Southeast region of the United States and in California. Ca. N. procyonis is widespread in raccoon populations, but the spatial variation in prevalence may be related to vector distribution or another ...

Epistaxis and Intradural–Extramedullary Haemorrhage in a Dog With Steroid Responsive Meningitis‐Arteritis

open access: yesVeterinary Medicine and Science, Volume 11, Issue 1, January 2025.
This case report describes an uncommon presentation of SRMA in a dog, with epistaxis, spinal haemorrhage and absence of classical clinical signs like cervical or thoracolumbar hyperaesthesia which was successfully treated with a combined approach of surgical decompression of the spinal cord, via a right‐sided hemilaminectomy at the level of L2/L3 with ...

PERSISTENT EHRLICHIA CHAFFEENSIS INFECTION IN WHITE-TAILED DEER [PDF]

open access: yesJournal of Wildlife Diseases, 2001
Four white-tailed deer (Odocoileus virginianus) were inoculated intravenously with a deer-origin isolate (15B-WTD-GA) of Ehrlichia chaffeensis. The course of infection was monitored using indirect fluorescent antibody (IFA), polymerase chain reaction (PCR), and culture over a 9 m period. All deer became rickettsemic within 24 days post inoculation (DPI)

Molecular Detection and Characterization of Ehrlichia ruminantium [PDF]

open access: yes, 2002
Ehrlichia ruminantium is an obligate intracellular bacterium that can cause a disease in ruminants known as heartwater. The vertebrate host becomes infected when infected Amblyomma ticks (nymphs or adults) feed on it. When the host survives the infection

Ehrlichia chaffeensis Tandem Repeat Proteins are Related to the RTX Family of Toxins and Secreted by the Type 1 Secretion System

open access: yesFrontiers in Cellular and Infection Microbiology, 2011
Ehrlichia chaffeensis has type 1 and 4 secretion systems (T1SS and T4SS), but the substrates have not been identified. Potential substrates include secreted tandem repeat protein (TRP) 47, TRP120, and TRP32, and the ankyrin repeat protein, Ank200, that ...

Ticks From Mink and Their Associated Microorganisms in Spain

open access: yesTransboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Wildlife is an important source of emerging zoonotic agents, including tick‐borne ones. Wild carnivores such as mink are commonly parasitized by ticks, which are vectors and reservoirs of zoonotic diseases. Besides the importance of these arthropods as potential sources of diseases in mink, and the role of these mammals as reservoirs of infectious ...

Transmission electron microscopy reveals distinct macrophage- and tick cell-specific morphological stages of Ehrlichia chaffeensis. [PDF]

open access: yesPLoS ONE, 2012
Ehrlichia chaffeensis is an emerging tick-borne rickettsial pathogen responsible for human monocytic ehrlichiosis. Despite the induction of an active host immune response, the pathogen has evolved to persist in its vertebrate and tick hosts ...
