Influenza A virus causes respiratory disease in both humans and animals. In this study, a survey of influenza A antibodies in domestic dogs and cats was conducted in 47 animal shelters in 19 provinces of Thailand from September 2011 to September 2014. One thousand and eleven serum samples were collected from 932 dogs and 79 cats. Serum samples were tested for influenza A antibodies using a multi-species competitive NP-ELISA and haemagglutination inhibition (HI) assay. The NP-ELISA results showed that 0.97% (9/932) of dogs were positive, but all cat samples were negative. The HI test against pandemic H1N1, human H3N2 and canine H3N2 showed that 0.64% (6/932) and 1.20% (1/79) of dogs and cats were positive, respectively. It is noted that all six serum samples (5 dogs and 1 cat) had antibodies against pandemic H1N1. In summary, a serological survey revealed the evidence of pandemic H1N1 influenza exposure in both dogs and cats in the shelters in Thailand.

To characterize the population structure, antimicrobial resistance and virulence genes of Klebsiella spp. isolated from dogs, cats and humans with urinary tract infections (UTIs).


Klebsiella spp. from companion animals (n = 27) and humans (n = 77) with UTI were tested by the disc diffusion method against 29 antimicrobials. Resistant/intermediate isolates were tested by PCR for 16 resistance genes. Seven virulence genes were screened for by PCR. All Klebsiella pneumoniae from companion animals and third-generation cephalosporin (3GC)-resistant isolates from humans were typed by MLST. All Klebsiella spp. were compared after PFGE XbaI macro-restriction using Dice/UPGMA with 1.5% tolerance.


blaCTX-M-15 was detected in >80% of 3GC-resistant strains. K. pneumoniaehigh-risk clonal lineage ST15 predominated in companion animal isolates (60%, n = 15/25). Most companion animal ST15 K. pneumoniae belonged to two PFGE clusters (C4, C5) that also included human strains. Companion animal and human ST15-CTX-M-15 K. pneumoniae shared a fimH-1/mrkD/entB/ycfM/kfu virulence profile, with a few (n = 4) also harbouring the yersiniabactin siderophore-encoding genes. The hospital-adapted ST11 K. pneumoniae clonal lineage was detected in a cat (n = 1) and a human (n = 1); both were MDR, had 81.1% Dice/UPGMA similarity and shared several virulence and resistance genes. Two 3GC-resistant ST348 strains with 86.7% Dice/UPGMA similarity were isolated from a cat and a human.


Companion animals with UTI become infected with high-risk K. pneumoniaeclonal lineages harbouring resistance and virulence genes similar to those detected in strains from humans. The ST15-CTX-M-15 K. pneumoniae clonal lineage was disseminated in companion animals with UTI. Caution must be applied by companion animal caretakers to avoid the spread of K. pneumoniaehigh-risk clonal lineages.

“What greater gift than the love of a cat?”—Charles Dickens, Great Expectations

Avian influenza viruses have rarely been detected in cats and, until 2016, no cat had ever been documented to have an influenza A(H7N2) virus infection or to transmit the virus to a human. In December 2016, the New York City Department of Health and Mental Hygiene (NYC DOHMH) was alerted about a cat admitted to a Manhattan animal shelter on 12 November 2016 that subsequently died and was confirmed positive for influenza A(H7N2) virus, a low-pathogenic avian influenza virus [1, 2].

In 2016, an influenza A(H7N2) virus outbreak occurred in cats in New York City’s municipal animal shelters. One human infection was initially detected.


We conducted a serological survey using a novel approach to rule out cross-reactive antibodies to other seasonal influenza viruses to determine whether additional A(H7N2) human infections had occurred and to assess exposure risk.


Of 121 shelter workers, one had serological evidence of A(H7N2) infection, corresponding to a seroprevalence of 0.8% (95% confidence interval, .02%–4.5%). Five persons exhibited low positive titers to A(H7N2) virus, indicating possible infection; however, we could not exclude cross-reactive antibody responses to seasonal influenza viruses. The remaining 115 persons were seronegative. The seropositive person reported multiple direct cat exposures without using personal protective equipment and mild illness with subjective fever, runny nose, and sore throat.


We identified a second case of A(H7N2) infection from this outbreak, providing further evidence of cat-to-human transmission of A(H7N2) virus.

In December 2016, highly pathogenic avian influenza (HPAI) infection with systemic pathological lesions was found in cats in South Korea. Genetic analyses indicated that the feline isolates were similar to HPAI H5N6 viruses isolated in chicken farms nearby. This finding highlights the need for monitoring of domestic mammals during HPAI outbreaks.

Feline infectious peritonitis (FIP), one of the most important lethal infections of cats, is caused by feline infectious peritonitis virus (FIPV), the high-virulence biotype of feline coronaviruses (FCoVs). FIPVs are suggested to emerge from feline enteric coronaviruses (FECVs) by acquiring mutations in specific genes in the course of persistent infections. Although numerous studies identified mutations predicted to be responsible for the FECV-FIPV biotype switch, the presumed roles of specific genetic changes in FIP pathogenesis have not been confirmed experimentally. Reverse genetics systems established previously for serotype I and the less common serotype II FCoVs were based on cell culture-adapted FIPV strains which, however, were shown to be unsuitable for FIP pathogenesis studies in vivo. To date, systems to produce and manipulate recombinant serotype I field viruses have not been developed, mainly because these viruses cannot be grown in vitro. Here, we report the first reverse genetics system based on a serotype I FECV field isolate that is suitable to produce high-titer stocks of recombinant FECVs. We demonstrate that these recombinant viruses cause productive persistent infections in cats that are similar to what is observed in natural infections. The system provides an excellent tool for studying FCoVs that do not grow in standard cell culture systems and will greatly facilitate studies into the molecular pathogenesis of FIP. Importantly, the system could also be adapted for studies of other RNA viruses with large genomes whose production and characterization in vivo are currently hampered by the lack of in vitro propagation systems.



The availability of recombinant serotype I FCoV field isolates that are amenable to genetic manipulation is key to studying the molecular pathogenesis of FIP, especially since previous studies using cell culture-adapted FIPVs had proven unsuccessful. To our knowledge, we report the first serotype I FECV field isolate-based reverse genetics system that allows the production of high-titer recombinant virus stocks that can be used for subsequent in vivo studies in cats. The system represents a milestone in FCoV research. It provides an essential tool for studying the molecular pathogenesis of FIP and, more specifically, the functions of specific gene products in causing a fundamentally different progression of disease following acquisition of specific mutations. The system developed in this study will also be useful for studying other coronaviruses or more distantly related RNA viruses with large genomes for which suitable in vitroculture systems are not available.

We report detection and full-genome characterization of a novel orthopoxivirus (OPXV) responsible for a fatal infection in a cat. The virus induced skin lesions histologically characterized by leukocyte infiltration and eosinophilic cytoplasmic inclusions. Different PCR approaches were unable to assign the virus to a defined OPXV species. Large amounts of typical brick-shaped virions, morphologically related to OPXV, were observed by electron microscopy. This OPXV strain (Italy_09/17) was isolated on cell cultures and embryonated eggs. Phylogenetic analysis of 9 concatenated genes showed that this virus was distantly related to cowpox virus, more closely related to to ectromelia virus, and belonged to the same cluster of an OPXV recently isolated from captive macaques in Italy. Extensive epidemiologic surveillance in cats and rodents will assess whether cats are incidental hosts and rodents are the main reservoir of the virus. The zoonotic potential of this novel virus also deserves further investigation.
