The potential risk of international spread of Mycobacterium bovis associated with movement of alpacas
2022
Krajewska-Wędzina Monika | Miller Michele A. | Didkowska Anna | Kycko Anna | Radulski Łukasz | Lipiec Marek | Weiner Marcin
The study highlights the transboundary nature of tuberculosis (TB) in alpacas and the failure of current ante-mortem testing protocols (the tuberculin skin and Enferplex Camelid TB tests) to identify TB-free alpaca herds and individuals for export. Our research and the available literature indicate that the alpaca (Vicugna pacos) is extremely susceptible to Mycobacterium bovis infection, and that testing periodicity fails to take into account that animals do not manifest disease symptoms for a long time. The skin test failed to identify Mycobacterium bovis infection in two alpacas prior to their movement from the UK to Poland. The animals were purchased by a breeding centre in Poland, and were then shown at an international animal exhibition. The last owner of the alpacas before their deaths from TB bought the infected animals unwittingly in order to run rehabilitation activities with disabled children on his farm.

Dairy cows may infrequently give milk tinged with blood after calving, which is a condition termed haemolactia. Economic losses for dairy farmers are caused by cases of haemolactia because of the condemnation of such milk, potential contamination of good bulk tank milk with haemolactic milk, and need for veterinarian intervention. This study was performed to elucidate the oxidative status of dairy cows with haemolactia during the peripartum period.

2022
Deng Chao-Yang | Zhu Ting-Ting | Lian Shuai | Wang Jian-Fa | Wu Rui | Zheng Jia-San
Hypoxia is a common pathological condition after spinal cord injury. Oestrogen-related receptor alpha (ERRα), as a key regulator of energy metabolism and mitochondrial functions, plays an important role in maintaining cell homeostasis. However, its role in hypoxic spinal microglia has not been fully elaborated. This study investigated the receptor’s activity when these cells are hypoxic and used as an in vitro model.

The aim of the study was to investigate the relationship between biosecurity as scored on the Italian National Animal Welfare Reference Centre (Centro di Referenza Nazionale per il Benessere Animale – CReNBA) checklist and the prevalence of Mycobacterium avium subsp. paratuberculosis, Chlamydophila abortus and Neospora caninum on dairy farms located in Ragusa, Italy.

Trypanosomosis is an important disease of dromedary camels caused by the pathogenic protozoan Trypanosoma evansi. This study aimed to compare three different tests for its diagnosis in this species: conventional microscopy, the card agglutination test for trypanosomosis/T. evansi (CATT/T. evansi) and real-time PCR.

2022
Badr Yassien | Rahman Md. Matiur | Ohno Yoshito | Ishijima Keita | Maeda Ken | Kohyama Kaoru | Kamatari Yuji O. | Shimizu Kaori | Okada Ayaka | Inoshima Yasuo
Seal parapoxvirus (SPPV) infection has been reported among pinnipeds in aquaria in Japan; however, its seroprevalence is unknown. Therefore, an enzyme-linked immunosorbent assay (ELISA) was developed for serological diagnosis of SPPV infection.
Mostrar más [+] Menos [-]Antibiotic susceptibility of mycobacteria isolated from ornamental fish
2022
Guz Leszek | Puk Krzysztof
Nontuberculous mycobacteria (NTM) are increasingly recognised as causative agents of opportunistic infections in humans for which effective treatment is challenging. There is very little information on the prevalence of NTM drug resistance in Poland. This study was aimed to evaluate the susceptibility to antibiotics of NTM, originally isolated from diseased ornamental fish.
Mostrar más [+] Menos [-]Molecular detection, risk factors and public awareness of avian bornavirus among captive and non-captive birds in Peninsular Malaysia
2022
Lutpi Syamsiah Mohd | Abu Jalila | Arshad Siti Suri | Rahaman Nor Yasmin
Proventricular dilatation disease (PDD) is caused by avian bornavirus (ABV) has been identified in psittacine, non-psittacine birds and waterfowl. Birds may show signs of gastrointestinal tract deficit or neurological dysfunction or even both. The objectives of this study were to determine the molecular prevalence, risk factors and public awareness of ABV and PDD among captive and non-captive birds in Peninsular Malaysia.
Mostrar más [+] Menos [-]Evaluation of a real-time PCR in combination with a cultivation method for the detection of Brucella abortus in organs of infected cattle in southern Italy
2022

Brucellosis is a widespread zoonosis of great economic importance for livestock farming in many areas of the world. It is a highly infectious disease which is diagnosed using conventional serological and microbiological methods. The aim of this study was to assess the efficiency of a specific real-time PCR in combination with broth cultivation in detecting Brucella spp. in organs of infected cattle, in order to compare the sensitivity of the two approaches and the time needed in them until a correct diagnosis is made.
Mostrar más [+] Menos [-]Analysis of antimicrobial resistance and genetic correlations of Escherichia coli in dairy cow mastitis
2022
Li Ke | Hou Mingyuan | Zhang Lin | Tian Mengyue | Yang Ming | Jia Li | Liang Yanyan | Zou Dongmin | Liu Ruonan | Ma Yuzhong
Escherichia coli is a widespread environmental pathogen frequently causing dairy cow mastitis. This bacterium is particularly capable of acquiring antimicrobial resistance, which can have severe impacts on animal food safety and human health. The objective of the study was to investigate antimicrobial resistance and genetic correlations of E. coli from dairy cow mastitis cases in northern China.
