Detection of mip-like sequences and mip-related proteins within the family Rickettsiaceae
Current Microbiology, 1995The Mip surface protein, a prokaryotic analog of the FK506-binding proteins, enhances the ability of Legionella pneumophila to infect macrophages and protozoa. Using mip-specific probes and low-stringency Southern hybridizations, we have detected DNA sequences homologous to mip within Coxiella burnetii and Rochalimaea quintana.

Antigenic Properties of the Ehrlichiae and other Rickettsiaceae
1990The family Rickettsiaceae consists of a diverse group of small gram-negative bacteria, most of which show intimate association with diverse arthropods and exhibit obligate intracellular growth. The chemical and antigenic properties of members of the tribe Rickettsieae (Rickettsia, Rochalimaea, Coxiella) are understood relatively well in contrast to ...

The present study was carried out to identify Rickettsia species with zoonotic potential in ticks collected from dogs in a rural area in Tabasco, Mexico. In total 197 Amblyomma maculatum ticks were collected from 40 domestic dogs. The collected specimens were pooled and subjected to DNA extraction.

TheRickettsiaceae, Anaplasmataceae,andCoxiellaceae
2016Organisms belonging to the families Rickettsiaceae, Anaplasmataceae, and Coxiellaceae are a diverse group of intracellular bacteria that cause a variety of infections in humans. As in the case of the Rickettsiaceae and Anaplasmataceae, hematophagous arthropod vectors play a role in maintaining the agents in nature and transmit the agents to cause ...

Genome sequences of 36 Rickettsia and Orientia were analyzed using Formal Order Analysis (FOA). This approach takes into account arrangement of nucleotides in each sequence. A numerical characteristic, the average distance (remoteness) - "g" was used to compare of genomes.

[Lipopolysaccharides of Rickettsiaceae and the Limulus endotoxin assay].
Giornale di batteriologia, virologia ed immunologia, 1981The A.A. have examined by Limulus endotoxin assay some LPS preparations from R. typhi, R. slovaka, C. burnetti phase I and II, as a demonstration of endotoxicity. All the preparations tested were able to gel the Limulus amoebocyte lysates, even if to a different degree of reactivity.

Antibodies against Rickettsiaceae in dogs of Setúbal, Portugal.
Central European journal of public health, 1995An indirect fluorescent antibody test was performed on sera collected from dogs housed in the municipal kennel of Setúbal to assess the prevalence of antibodies to Ehrlichia canis, the causative agent of canine ehrlichiosis and to Rickettsia conorii, agent of boutonneuse fever in humans. Two other members of the family Rickettsiaceae, Coxiella burnetii

Bel den Bakterien der Familien Rickettsiaceae (Genera Rlckettsia und Orientia), Anaplasmataceae (Genera Anaplasma, Ehrlichia und Neorickettsia) und Coxiellaceae (Genus Coxlella) handelt es sich um kleine gram-negative Stabchen, die sich nur in Wirtszellen vermehren konnen (obligat intrazellulare Bakterien) (⊡ Tab. 47.1 ).

Much progress has been made in one's understanding of the mechanism of rickettsial actin-based motility, although the process of cell-to-cell spread remains poorly understood. This chapter examines historical and recent developments in our understanding of how rickettsiae establish intracellular infection.
