[Prospects for the correction of intestinal microbiota in the prevention and treatment of asthma in children].

Vopr Pitan 2021 22;90(4):74-83. Epub 2021 Jul 22.

I.M. Sechenov First Moscow State Medical University of Ministry of Healthcare of the Russian Federation (Sechenov University), 119991, Moscow, Russian Federation.

The issues of therapy and prevention of asthma in children do not lose their relevance. The increase in the prevalence of allergic diseases and asthma is associated, among other things, with a relative deficit in the microbial load and changes in the microbiota due to improved hygiene and living conditions. The microbiota plays an important role in the formation and functioning of the immune system. Read More

The effects of raw-meat diets on the gastrointestinal microbiota of the cat and dog: a review.

N Z Vet J 2021 Sep 19:1-9. Epub 2021 Sep 19.

Smart Foods, AgResearch Limited, Palmerston North, New Zealand.

The aim of this review is to summarise the available literature on the effects of consuming raw, red meat diets on the gastrointestinal microbiome of the cat and dog. In recent years, feeding raw meat diets to cats and dogs has increased, in part associated with trends in human nutrition for "natural" and "species-appropriate" diets. These diets range from home-prepared unprocessed, nutritionally incomplete diets to complete and balanced diets with sterilisation steps in their manufacturing process. Read More

Animal reservoirs of SARS-CoV-2: calculable COVID-19 risk for older adults from animal to human transmission.

Geroscience 2021 Aug 30. Epub 2021 Aug 30.

Vascular Cognitive Impairment and Neurodegeneration Program, Center for Geroscience and Healthy Brain Aging, Department of Biochemistry and Molecular Biology, University of Oklahoma Health Sciences Center, Oklahoma City, OK, USA.

The current COVID-19 pandemic, caused by the highly contagious respiratory pathogen SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), has already claimed close to three million lives. SARS-CoV-2 is a zoonotic disease: it emerged from a bat reservoir and it can infect a number of agricultural and companion animal species. SARS-CoV-2 can cause respiratory and intestinal infections, and potentially systemic multi-organ disease, in both humans and animals. Read More

In Vitro-In Silico Tools for Streamlined Development of Acalabrutinib Amorphous Solid Dispersion Tablets.

Pharmaceutics 2021 Aug 13;13(8). Epub 2021 Aug 13.

Global Research & Development, Lonza, Bend, OR 97703, USA.

Amorphous solid dispersion (ASD) dosage forms can improve the oral bioavailability of poorly water-soluble drugs, enabling the commercialization of new chemical entities and improving the efficacy and patient compliance of existing drugs. However, the development of robust, high-performing ASD dosage forms can be challenging, often requiring multiple formulation iterations, long timelines, and high cost. In a previous study, acalabrutinib/hydroxypropyl methylcellulose acetate succinate (HPMCAS)-H grade ASD tablets were shown to overcome the pH effect of commercially marketed Calquence in beagle dogs.

Cystinuria in Dogs and Cats: What Do We Know after Almost 200 Years?

Animals (Basel) 2021 Aug 19;11(8). Epub 2021 Aug 19.

Faculty of Veterinary Medicine, University of Veterinary Sciences, 612 42 Brno, Czech Republic.

The purpose of this review is to summarize current knowledge on canine and feline cystinuria from available scientific reports. Cystinuria is an inherited metabolic defect characterized by abnormal intestinal and renal amino acid transport in which cystine and the dibasic amino acids ornithine, lysine, and arginine are involved (COLA). At a normal urine pH, ornithine, lysine, and arginine are soluble, but cysteine forms a dimer, cystine, which is relatively insoluble, resulting in crystal precipitation. Read More

J Pharmacol Toxicol Methods 2021 Aug 17:107110. Epub 2021 Aug 17.

Merck KGaA, Chemical and Preclinical Safety, Darmstadt, Germany.

Introduction: Gastrointestinal (GI) toxicity is still an issue within drug development, especially for novel oncology drugs. The identification of GI mucosal damage at an early stage with high sensitivity and specificity across preclinical species and humans remains difficult. To date, in preclinical studies, no qualified mechanistic, diagnostic or prognostic biomarkers exist for GI mucosal toxicity. Read More

Hierarchical modelling of immunoglobulin coated bacteria in dogs with chronic enteropathy shows reduction in coating with disease remission but marked inter-individual and treatment-response variability.

PLoS One 2021 19;16(8):e0255012. Epub 2021 Aug 19.

Department of Veterinary Clinical Sciences, Melbourne Veterinary School, The University of Melbourne, Werribee, Victoria, Australia.

Chronic enteropathies are a common problem in dogs, but many aspects of the pathogenesis remain unknown, making the therapeutic approach challenging in some cases. Environmental factors are intimately related to the development and perpetuation of gastrointestinal disease and the gut microbiome has been identified as a contributing factor. Previous studies have identified dysbiosis and reduced bacterial diversity in the gastrointestinal microbiota of dogs with chronic enteropathies. Read More

Pathogens 2021 Jul 5;10(7). Epub 2021 Jul 5.

Institute of Parasitology, Vetsuisse and Medical Faculty, University of Zurich, 8057 Zurich, Switzerland.

The detection of in infected canids and the environment is pivotal for a better understanding of the epidemiology of alveolar echinococcosis in endemic areas. Necropsy/sedimentation and counting technique remain the gold standard for the detection of canid infection. PCR-based detection methods have shown high sensitivity and specificity, but they have been hardly used in large scale prevalence studies. Read More

Department of Animal Medicine and Surgery, College of Veterinary Medicine, Complutense University of Madrid, Avda. Puerta de Hierro s/n, 28040, Madrid, Spain.

The gut associated lymphoid tissue (GALT) effector sites play a crucial role on the pathogenesis of many immune-mediated gastrointestinal diseases. The lymphocytes at these effector sites are principally T cells which present important morphological, phenotypical and functional differences. Flow cytometry (FC) is one of the most commonly used techniques to characterize intestinal lymphocytes in human and animal models. Read More

Spread of anthelmintic resistance in intestinal helminths of dogs and cats is currently less pronounced than in ruminants and horses - Yet it is of major concern.

Int J Parasitol Drugs Drug Resist 2021 Jul 25;17:36-45. Epub 2021 Jul 25.

Institute of Parasitology, University of Zurich, Switzerland.

Anthelmintic resistance (AR) has thus far only rarely been reported for intestinal helminths of dogs and cats, in contrast to parasites of livestock and horses. We highlight possible reasons for this striking and important discrepancy, including ecological, biological and genetic factors and/or intervention regimens of key intestinal helminths concerning both host groups. In view of the current knowledge related to the genetics, mechanisms and principles of AR development, we point at issues which in our view contribute to a comparatively lower risk of AR development in intestinal helminths of dogs and cats.

Instituto Oswaldo Cruz-Laboratório de Estudos Integrados em Protozoologia, Rio de Janeiro, Brazil.

Intestinal cryptosporidiosis is a diarrheal disease caused by protists of genus Cryptosporidium that infect a wide variety of hosts, primarily vertebrates. Due to the close contact between humans and their companion animals, especially dogs and cats, there is concern about the potential for zoonotic transmission of this enteric protozoan parasite by infected animals. This study aimed to perform a microscopic and molecular diagnosis of Cryptosporidium spp. Read More

Full Genomic Sequences of H5N1 Highly Pathogenic Avian Influenza Virus in Human Autopsy Specimens Reveal Genetic Variability and Adaptive Changes for Growth in MDCK Cell Cultures.

Biomed Res Int 2021 22;2021:3890681. Epub 2021 Jul 22.

Center for Research and Innovation, Faculty of Medical Technology, Mahidol University, Nakhon Pathom 73170, Thailand.

The entire H5N1 highly pathogenic avian influenza viral genomes were identified in the frozen autopsy specimens: the trachea, lung, colon, and intestinal feces from a patient who died of the disease in 2006. Phylogenetic analysis of the viral genomes showed that these viruses belonged to clade 1 and were the reassortants generated from the reassortment of the viruses within the same clade. The sequencing data from the autopsy specimens revealed at least 8 quasispecies of the H5N1 viruses across all 4 specimen types. Read More
