Diet and coexistence of Rattus rattus rattus (Linnaeus), Rattus exulans (Peale) and Rattus norvegicus (Berkenhout) on Stewart Island, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology [PDF]

open access: yes, 1988
Coexistence and diet of Rattus rattus rattus, Rattus exulans and, Rattus norvegicus on Stewart Island was investigated by snap-trapping and stomach analysis. The trapping period was from June 1982 to December 1986.

Generating golden Syrian hamsters with conditional alleles via zygote microinjection of CRISPR/Cas9

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We established the first conditional knockout (cKO) model in the golden Syrian hamster by CRISPR/Cas9‐mediated genome editing. Cas9 protein, two sgRNAs, and a donor plasmid carrying loxP‐flanked exon 2 of the ApoF gene were microinjected into one‐cell embryos. The floxed allele was efficiently generated (up to 27%) and transmitted through the germline.

Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

open access: yesThe Anatomical Record, EarlyView.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Morphologic, Morphometric and Molecular Comparison of Two Sister Species of Rodents as Potential Reservoir Hosts of Zoonotic Cutaneous Leishmaniasis in the Southwest of Iran

open access: yesJournal of Medical Microbiology and Infectious Diseases, 2019
Introduction: Rodents are reservoir hosts of various infectious diseases. Many species and subspecies of genus Rattus play a significant role as potential reservoir hosts of different emerging and re-emerging diseases, including leishmaniasis.

Native rodent species are unlikely sources of infection for Leishmania (Viannia) braziliensis along the Transoceanic Highway in Madre de Dios, Peru. [PDF]

open access: yes, 2014
An estimated 2.3 million disability-adjusted life years are lost globally from leishmaniasis. In Peru's Amazon region, the department of Madre de Dios (MDD) rises above the rest of the country in terms of the annual incidence rates of human leishmaniasis.

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

open access: yesThe Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...
