The present study reports the occurrence of rotavirus A (RVA), rotavirus D (RVD), rotavirus F (RVF), rotavirus G (RVG), and picobirnavirus (PBV) in fecal specimens of wild (n = 22), and exotic birds (n = 1) from different cities of Pará state. These animals were hospitalized at Veterinary Hospital of the Federal University of Pará, Brazil, in a period from January 2018 to June 2019. The animals exhibited different clinical signs, such as diarrhea, malnutrition, dehydration, and fractures. The results showed 39.1% (9/23) of positivity for RVA by RT-qPCR. Among these, one sample (1/9) for the NSP3 gene of T2 genotype was characterized. About 88.9% (8/9) for the VP7 gene belonging to G1, G3 equine like and G6 genotypes, and 55.5% (5/9) for the VP4 gene of P[2] genotype were obtained. In the current study, approximately 4.5% of the samples (1/23) revealed coinfection for the RVA, RVD and RVF groups. Furthermore, picobirnavirus (PBV) was detected in one of the 23 samples tested, and was classified in the Genogroup I. The findings represent the first report of RVA, RVD, RVF, RVG, and PBV genotypes in wild birds in Brazil, and due to wide distribution it can implies potential impacts of RVs, and PBVs on avian health, and other animals contributing to construction of new knowledge, and care perspectives.

ABSTRACTThe present study reports the detection and molecular characterization of rotavirus A (RVA), rotavirus D (RVD), rotavirus F (RVF), rotavirus G (RVG) and picobirnavirus (PBV) in fecal specimens of wild and exotic birds (n = 23) from different cities of Pará state, which were hospitalized at Veterinary Hospital of the Federal University of Pará, Brazil, between January 2018 to June 2019. The animals exhibited different clinical signs, such as diarrhea, malnutrition, dehydration and fractures. The results showed 39.1% (9/23) of positivity for RVA by RT-qPCR. Among these, one sample (1/9) for the NSP3 gene of T2 genotype was characterized. About 88.9% (8/9) for the VP7 gene belonging to G1, equine-like G3 and G6 genotypes, and 55.5% (5/9) for the VP4 gene of P[2] genotype were obtained. In the current study, approximately 4.5% of the samples (1/23) revealed coinfection for the RVA, RVD and RVF groups. Furthermore, picobirnavirus (PBV) was detected in 1 of the 23 samples tested and was classified in the Genogroup I. The findings represent the first report of the circulation of RVA, RVD, RVF, RVG and PBV genotypes in wild birds in Brazil and suggest the possible interspecies transmission of RVs and PBVs.

Cruzi Infection

In order to verify the Trypanosoma cruzi infection in domestic domiciled dogs in a rural endemic area from the south region of the State of Bahia, Polymerase Chain Reaction (PCR) were performed using S35 and S36 primers in 272 dogs living in the district of Vila Operaria, in the municipality of Buerarema. All animals were clinically evaluated; 2.5 mL of blood were collected through venipuncture for the performance of molecular tests. None of these animals showed clinical signs of the illness and only two were identified with the DNA parasite. This result is the first report of natural infection by T. cruzi in domestic dogs in southern Bahia.

Pyometra is a pus accumulation in the uterine lumen. This paper reports an unusual case of pyometra in a female Sus scrofa of Parque Biologico de Gaia (Avintes, Portugal). The animal was of advanced age, and the clinical signs (e.g., anorexia, lethargy) were originally associated with geriatric conditions. The animal presented a large uterus, which likely further contributed to the locomotion difficulties and poor body condition. To the extent of our knowledge, this is the first report of a close pyometra in wild boar (Sus scrofa, Linnaeus, 1758). However, this diagnosis must be taken into account during uterine evaluation and special attention must be given to its inspection in meat animals.

Rotaviruses are a major etiologic agent of gastroenteritis in infants and young children worldwide. To learn the shift of genotypes and genetic characteristics of Rotavirus A (RVA) causing diarrhea in children and adults, a hospital-based surveillance of rotavirus was conducted in Wuhan, China from June 2011 through May 2019, and representative virus strains were phylogenetically analyzed. Among a total of 6733 stool specimens collected from both children and adults with acute gastroenteritis, RVA was detected in 25.5% (1125/4409) and 12.3% (285/2324) of specimens, respectively. G9P[8] was the most common genotype (74.5%), followed by G1P[8] (8.7%), G2P[4] (8.4%), and G3P[8] (7.3%), with G9P[8] increasing rapidly during the study period. The predominant genotype shifted from G1P[8] to G9P[8] in 2012–2013 epidemic season. G12P[6] strain RVA/Human-wt/CHN/Z2761/2019/G12P[6] was detected in April 2019 and assigned to G12-P[6]-I1-R1-C1-M1-A1-N1-T2-E1-H1 genotypes. Phylogenetic analysis revealed that VP7, VP4, VP6, VP3, NSP1, NSP2, and NSP5 genes of Z2761 clustered closely with those of Korean G12P[6] strain CAU_214, showing high nucleotide identities (98.0–98.8%). The NSP3 gene of Z2761 was closely related to those of G2P[4] and G12P[6] rotaviruses in Asia. All the eleven gene segments of Z2761 kept distance from those of cocirculating G9P[8], G1P[8], and G3P[8] strains detected in Wuhan during this study period. This is the first identification of G12 rotavirus in China. It is deduced that Z2761 is a reassortant having DS-1-like NSP3 gene in the background of G12P[6] rotavirus genetically close to CAU_214.

Proximal Urethra

Congenital urethral strictures are well recognised in human beings and have recently been described in two cats but have not been previously reported in dogs. A 10-month-old female English Bull Terrier presented with a life-long history of being unable to pass a normal stream of urine. Urethrocystoscopy confirmed the presence of a stricture lesion in the proximal urethra. This thin, membranous structure was effaced under endoscopic visualisation using a 10 mm diameter balloon-dilation catheter. Complete and sustained resolution of clinical signs occurred after a single dilation procedure. To the best of our knowledge, this is the first report of a congenital urethral stricture in a dog and the term congenital obstructive proximal urethral membrane may be useful for describing these lesions in the future.

This first survey in 2009 and 2010 on silica-scaled Chrysophytes in Zhenbao Island Wetland Preserve, Northeast China, recorded 32 taxa (5 in Chrysophyceae and 27 in Synurophyceae), of which 29 were previously found in other parts of China, three species, Spiniferomonas serrata, Mallomonas transsylvanica and Synura punctulosa are new records to China. In terms of biogeography, 1 taxon is endemic, 2 bipolar, 1 northern temperate, 9 cosmopolitan, and 18 of wide distribution. The endemism of Synura punctulosa, appears due to its poor dispersal ability; lack of sampling data may also contribute its known distribution range. Spiniferomonas serrata and Mallomonas transsylvanica, two bipolar taxa, are the first report in China. More research efforts are needed for adequately understanding the distributions of this group of algae.

A 16-week-old Persian kitten was referred for investigation of constipation and failure to grow. The owner reported that the kitten had always strained to defecate. Abdominal radiographs confirmed megacolon and CT pneumocolography confirmed the presence of a caudal rectal stricture. During a single procedure and under fluoroscopic guidance, the stricture was effaced by sequentially dilating 10-mm and 15-mm balloons. Shortly after discharge, the owner reported complete resolution of clinical signs and oral laxatives were stopped. Repeat radiographs 1 month post dilation showed resolution of the diffuse megacolon and the cat appeared well and had gained weight. This is the first report of a congenital rectal stricture in a kitten and one of the few reports documenting balloon dilation for the treatment of stenotic anorectal lesions (congenital or acquired) in cats.

This epidemiological study was conducted to find out the incidence of Peste des Petits Ruminants (PPR) in goat and sheep at Upazilla Veterinary Hospital, Rangpur sadar, Rangpur during the period of January to April, 2014. In this period, 236 clinically infected goat and sheep were examined in which 22 (9.32%) PPR cases were diagnosed on the basis of history, clinical signs and gross pathological lesions. High fever (104-107 oC), mucopurulent oculo-nasal discharge, rapid and labored breathing, mouth lesion and diarrhea were the common clinical sign of PPR infected goat and sheep. The postmortem examination findings were dark red areas and congestion in different lobes of lungs, enlargement of spleen and lymph nodes, erosion of abomasums and characteristics zebra striping in the mucosa of colon. This present study reveals that about 7-12 months aged group of goats were more prone (40.91%) to PPR compare to adult (above 1 year) and Black Bengal goat was more susceptible (72.32%) than Jamunapari (27.78%) goat where the occurrence of PPR disease was more in goat (81.82%) than sheep (18.18%).Asian J.

New Host Records

Abstract The objective of this work was to evaluate the diversity of ticks associated with free-living animals and to investigate new host records for ticks. Ticks were collected from animals rescued during the flood of the Jamari River in the municipality of Ariquemes, state of Rondônia, North Region of Brazil. A total of 39 animals were captured, out of which 10 were amphibians, 19 were reptiles and 10 were mammals. A total of 127 ticks of the Amblyomma genus were collected from these animals, distributed among seven species: Amblyomma dissimile, Amblyomma geayi, Amblyomma humerale , Amblyomma longirostre, Amblyomma nodosum , Amblyomma rotundatum and Amblyomma varium. In addition, one specimen of Rhipicephalus (Boophilus) microplus was collected. Among these specimens, 85 were adults and 42 were nymphs, with A. rotundatum being the most prevalent species. An Amblyomma spp. larvae was also collected from a lizard (Uranoscodon superciliosus), and one Amblyomma calcaratum and one Amblyomma dubitatum were recovered from the environment, thus totaling 130 ticks. Among the Ixodidae collected from different hosts, we provide the first report for the species A. rotundatum parasitizing Rhinella major, U. superciliosus, Leptophis ahaetulla, Chironius multiventris, and Mastigodryas boddaerti, as well as of A. humerale parasitizing U. superciliosus, A. geayi parasitizing Choloepus didactylus, and Rhipicephalus (B.) microplus parasitizing Alouatta puruensis.
