Summary
This study details chewing lice (Amblycera and Ischnocera) in Mexico, compiling records from 1866-2017. It presents a checklist of 342 louse species found on 206 bird and 28 mammal hosts.
Area of Science:
- Zoology
- Entomology
- Parasitology
Background:
- Chewing lice (Phthiraptera: Amblycera and Ischnocera) in Mexico are poorly understood, with existing literature fragmented.
- Previous research primarily consists of isolated species records, hindering a comprehensive overview.
Purpose of the Study:
- To consolidate and summarize existing knowledge on chewing lice documented in Mexico.
- To create a comprehensive checklist of chewing lice species and their hosts in Mexico.
Main Methods:
- Conducted an exhaustive literature search covering publications from 1866 to 2017.
- Compiled data on chewing louse species, their avian and mammalian hosts, and geographical distribution within Mexico.
Main Results:
- Identified 342 species of chewing lice associated with Mexican fauna.
- Documented associations with 206 bird species and 28 mammal species.
- Compiled a host-parasite list and mapped the geographical distribution of these lice within Mexico.
Conclusions:
- This work provides the first consolidated checklist of chewing lice recorded from Mexico.
- The findings establish a baseline for future research on Phthiraptera diversity and host-parasite relationships in the region.

01:27Muscles of the Vertebral Column
3.3K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

01:28Articulations of the Vertebral Column
3.2K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

01:16Vertebral Column: Regions and Curvature
6.1K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

01:30Lytic Cycle of Bacteriophages
78.2K
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the...

02:23RNA Editing
9.9K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

01:19Contact-dependent Signaling
47.6K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.
