Dental disease in alpacas. Part 2: Risk factors associated with diastemata, periodontitis, occlusal pulp exposure, wear abnormalities, and malpositioned teeth

Journal of Veterinary Internal Medicine, 2020
Background Dental disorders, of which tooth root abscesses are best documented, are highly prevalent in alpacas. Identification of risk factors can be valuable for prevention of dental disorders in this species.

Using modern reproductive methods to hybridize old and new world Camelids : Camelus dromedarius x Lama guanicoe

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2000
A group of nine female and one male guanaco were maintained alongside a larger herd of dromedary camels at the Camel Reproduction Centre in Dubai. The ovaries of the female guanacos and camels were scanned regularly, and when they exhibited a dominant ...

Acute fasciolosis in an alpaca: a case report

BMC Veterinary Research, 2021
Background The popularity of new world camelids, particularly alpacas, is growing rapidly in Ireland, presenting a clinical challenge to veterinary practitioners who may not have worked with these species previously.

Prairie Rattlesnake Envenomation in 27 New World Camelids

Journal of Veterinary Internal Medicine, 2013
Abstract Background Morbidity and case fatality from rattlesnake envenomation is regionally specific because of variability in relative toxicity of the species of snake encountered. A previous report of rattlesnake envenomation in New World camelids (NWC) from the western coastal United States ...

How many large camelids in the world? A synthetic analysis of the world camel demographic changes

Pastoralism, 2020
At world level, the current official number of large camelids cannot be determined exactly (it is estimated to be more than 35 million heads), and the role of camels in the livestock economy is highly variable.

Evaluation of insulin secretion and action in New World camelids

American Journal of Veterinary Research, 2013
Abstract Objective—To measure and compare insulin secretion and sensitivity in healthy alpacas and llamas via glucose clamping techniques. Animals—8 llamas and 8 alpacas. Procedures—Hyperinsulinemic euglycemic clamping (HEC) and hyperglycemic clamping (HGC) were performed on each camelid in a crossover design with a minimum 48-hour washout period ...

Nucleotide diversity of functionally different groups of immune response genes in Old World camels based on newly annotated and reference-guided assemblies

BMC Genomics, 2020
Background Immune-response (IR) genes have an important role in the defense against highly variable pathogens, and therefore, diversity in these genomic regions is essential for species’ survival and adaptation.

A complete mitochondrial genome sequence of the wild two-humped camel (Camelus bactrianus ferus): an evolutionary history of camelidae

BMC Genomics, 2007
Background The family Camelidae that evolved in North America during the Eocene survived with two distinct tribes, Camelini and Lamini. To investigate the evolutionary relationship between them and to further understand the evolutionary history of this ...

Divergent Roles of mGlu2 and mGlu3 Receptors in Amyloid‐β Production and Cognitive Dysfunctions in Alzheimer's Disease

Advanced Science, EarlyView.
This study explores the opposing effects of the mGluR2 and mGluR3 receptors on amyloid precursor protein processing. mGluR2 promotes amyloidogenic cleavage, while mGluR3 favors non‐amyloidogenic pathways. Using a brain‐penetrant nanobody as a mGluR2 positive allosteric modulator, the study uncovers how its chronic activation aggravates amyloid‐β burden

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult
