Risk Factors for Human Lice and Bartonellosis among the Homeless, San Francisco, California, USA

Emerging Infectious Diseases, 2014
Homeless persons in San Francisco, California, USA, have been shown to have head and body lice infestations and Bartonella quintana infections. We surveyed a self-selected population of homeless persons in San Francisco to assess infestations of head and

Allee Effects May Slow the Spread of Parasites in a Coastal Marine Ecosystem [PDF]

, 2011
Allee effects are thought to mediate the dynamics of population colonization, particularly for invasive species. However, Allee effects acting on parasites have rarely been considered in the analogous process of infectious disease establishment and ...

Description of a new actinosporean type from South African freshwater [PDF]

, 2004
The 1st report on actinospores described these organisms as parasites related to myxosporeans. For a long time this group of parasites was believed to represent an independent taxonomic entity.

Evidence for an African cluster of human head and body lice with variable colors and interbreeding of lice between continents. [PDF]

PLoS ONE, 2012
BACKGROUND: Human head lice and body lice have been classified based on phenotypic characteristics, including geographical source, ecotype (preferred egg laying site hair or clothes), shape and color.

Data incongruence and the problem of avian louse phylogeny [PDF]

, 2004
Recent studies based on different types of data (i.e. morphological and molecular) have supported conflicting phylogenies for the genera of avian feather lice (Ischnocera: Phthiraptera).

On the origin of Halipeurus heraldicus on Round Island petrels: cophylogenetic relationships between petrels and their chewing lice [PDF]

, 2010
Lice phylogenetic relationships have often been used to elucidate host relationships and vice versa. In this study, we investigate the louse genus Halipeurus which parasitizes bird hosts in the families Procellariidae, Hydrobatidae and Pelecanoididae ...

Exploring the potential role of defensins in differential vector competence of body and head lice for Bartonella quintana

Parasites & Vectors, 2023
Background The body and head lice of humans are conspecific, but only the body louse functions as a vector to transmit bacterial pathogens such as Bartonella quintana. Both louse subspecies have only two antimicrobial peptides, defensin 1 and defensin 2.

Altitude-dependent Bartonella quintana Genotype C in Head Lice, Ethiopia

Emerging Infectious Diseases, 2011
To determine the presence of Bartonella quintana in head and body lice from persons in different locations in Ethiopia, we used molecular methods. B. quintana was found in 19 (7%) genotype C head lice and in 76 (18%) genotype A body lice. B.

Louse (Insecta : Phthiraptera) mitochondrial 12S rRNA secondary structure is highly variable [PDF]

, 2002
Lice are ectoparasitic insects hosted by birds and mammals. Mitochondrial 12S rRNA sequences obtained from lice show considerable length variation and are very difficult to align.

Lice community structure infesting Trinomys iheringi (Thomas, 1911) - Ocurrence, sex bias and climatic variables on tropical island

International Journal for Parasitology: Parasites and Wildlife, 2020
Few studies have provided information on parasitological indexes or other ecological characteristics of lice populations that parasitize small mammals in the Neotropical region.
