The occurrence of listeriosis in 12 caged canaries is described where 50% of the birds, including the female and all of the offspring, died within 2 weeks without clinical signs. At necropsy, multifocal necrotizing and partly granulomatous hepatitis, splenitis, myocarditis, interstitial nephritis, and exudative pericarditis with intra-lesional Listeria monocytogenes were the predominant findings as shown by histopathology and immunohistochemistry. Microbiology, serology and polymerase chain reaction revealed L. monocytogenes serotype 1/2a as the causative agent. Thus listeriosis has to be considered in the differential diagnosis for granulomas associated with mycobacteriosis, yersiniosis, coligranulomatosis or fungal infections.

An outbreak of Yersinia pseudotuberculosis (Yptb) occurred in a closed colony of Egyptian fruit bats (Rousettus aegyptiacus) and resulted in the death of seven bats over a 6-week period. An initial survey of the remaining bats revealed visceral abscessation characteristic of pseudotuberculosis in five of the 12 bats examined (41.7%), inciting depopulation of the colony. At necropsy, 70% of the 115 bats in the colony exhibited gross evidence suggestive of Yptb infection, including mesenteric lymphadenopathy (ML), hepatic abscessation (HA), and/or splenomegaly (SPM). Thirty of these bats (13 females and 17 males of various ages) were chosen at random and their tissues submitted for bacterial culture and histopathologic examination. Twenty-three of these 30 bats had one or more gross lesions considered consistent with Yptb, including ML, HA, and SPM. On histopathology, four of the 30 bats had necrotizing lesions containing Gram-negative bacteria in multiple organs, while 18 others exhibited mild mesenteric lymphadenitis and hepatitis. Four of the 30 bats had positive cultures for Yptb. Bats with gross evidence of mesenteric lymphadenopathy, splenomegaly, or histopathologic presence of demodicosis or bacteria in tissues were more likely (P < 0.05) to have a positive Yersinia culture. Examination of the correlation between population density and mortality rates of the colony revealed that the mortality rate of subadult bats increased dramatically at the time of the outbreak, when the population density was at its highest. It is suspected that stress, primarily from severe overcrowding, predisposed the bat colony to morbidity and mortality from this organism, which likely originated from a rodent reservoir.

An emaciated, free-ranging, sub-adult, male beaver (Castor canadensis) was found dead and was necropsied. Microscopically, the beaver had acute necrotizing hepatitis and splenitis with florid lobulated colonies of extracellular coccobacilli. Intravascular septic emboli were identified in lung, small intestine, and kidney, and discrete ulcers with scattered superficial extracellular accumulation of coccobacilli were noted on tail margins and plantar surfaces of the hind feet. Yersinia pseudotuberculosis was cultured on Columbia blood and MacConkey agar and identified by API 20E. Based on the pathology and acute mortality described in this case, as well as historical reports of Y. pseudotuberculosis related mortality in other beavers, this species could serve as a public health sentinel for localized occurrences of this bacterium.

A 2-year-old Pekinese dog was diagnosed with hepatic yersiniosis. Grossly, white-to-yellow nodules consisting of degenerated inflammatory cells, cell debris, and bacterial clumps were scattered throughout the liver. Histopathologically, suppurative and necrotizing hepatitis was apparent. Yersinia enterocolitica biotype 4, serotype O3 (4:O3) was identified and confirmed in the liver immunohistochemically, using a monoclonal antibody. The virulence genes ystA and ail were detected, but the isolate was negative for autoagglutination and calcium-dependent growth. To confirm systemic yersiniosis in animals, it is imperative that the organism(s) be identified because the hepatic lesions are similar to those of Y. pseudotuberculosis and other diseases, including plague, which is also a zoonotic pathogen.

A 49 years old Vietnamese male with a history of thalassemia, presented with gastrointestinal symptoms and signs of hemolysis. He was diagnosed with yersinia enterocolitis. Yersinia is a gram-negative rod that most frequently occurs in children especially during the winter months. In the current case, the bone marrow biopsy showed hemophagocytosis along with positive cultures for Yersinia. The microorganism likely triggered hemophagocytosis. This syndrome, also known as, hemophagocytic lymphohistiocytosis, is defined by fever for more than 7 d, cytopenia of two or more cell lines, hemophagocytosis, hepatitis, serum ferritin greater than 500, jaundice, lymphadenopathy, and hepatosplenomegaly. This disorder can be either familial or secondary to a strong immunologic activation. Both have an overwhelming activation of T-cells and macrophages.

Yersinia pseudotuberculosis is a recognized zoonotic food-borne pathogen; however, little is known about the ecology and epidemiology of diseases caused by the bacterium in California. The objective of the current study was to contribute to the knowledge of the diseases caused by Y. pseudotuberculosis in goats, the animal species most frequently reported with clinical yersiniosis to the California Animal Health and Food Safety Laboratory System, to better understand the epidemiology of this disease. A 23-year retrospective study was conducted to characterize the syndromes caused by the bacterium in goats and their temporospatial distribution, and to determine the number of cases in other animal species. Yersinia pseudotuberculosis-associated disease was diagnosed in 42 goats from 21 counties, with a strong seasonality in winter and spring. Most cases (88%) were observed within particular years (1999, 2004-2006, 2010-2011). The most frequently diagnosed syndrome was enteritis and/or typhlocolitis (64.3%), followed by abscessation (14.3%), abortion (11.9%), conjunctivitis (4.75%), and hepatitis (4.75%). Among other animal species, 59 cases were diagnosed in non-poultry avian species and 33 in mammals other than goats.

Grapes produce organic compounds that may be involved in the defense of the plants against invading phytopathogens. These metabolites include numerous phenolic compounds that are also active against human pathogens. Grapes are used to produce a variety of wines, grape juices, and raisins. Grape pomace, seeds, and skins, the remains of the grapes that are a byproduct of winemaking, also contain numerous bioactive compounds that differ from those found in grapes and wines. This overview surveys and interprets our present knowledge of the activities of wines and winery byproducts and some of their bioactive components against foodborne (Bacillus cereus, Campylobacter jejuni, Escherichia coli, Listeria monocytogenes, Salmonella enterica, Staphylococcus aureus, Yersinia enterocolitica, Vibrio cholerae, Vibrio vulnificus), medical (Helicobacter pylori, Klebsiella pneumoniae), and oral pathogenic bacteria, viruses (adeno, cytomegalo, hepatitis, noro, rota), fungi (Candida albicans, Botrytis cinerea), parasites (Eimeria tenella, Trichomonas vaginalis), and microbial toxins (ochratoxin A, Shiga toxin) in culture, in vivo, and in/on food (beef, chicken, frankfurters, hot dogs, lettuce, oysters, peppers, pork, sausages, soup, spinach) in relation to composition and sensory properties. Also covered are antimicrobial wine marinades, antioxidative and immunostimulating aspects, and adverse effects associated with wine consumption. The collated information and suggested research needs might facilitate and guide further studies needed to optimize the use of wines and byproducts to help improve microbial food safety and prevent or treat animal and human infections.

In February 2015, two Eurasian collared doves (Streptopelia decaocto) were submitted dead to the California Animal Health and Food Safety (CAHFS) Laboratory, Turlock branch, from a private aviary experiencing sudden, high mortality (4/9) in adult doves. In both doves, the gross and histologic lesions were indicative of acute, fatal septicemia. Grossly, there were numerous pale yellow foci, 1 to 2 mm in diameter, in the liver and spleen. Microscopically, these foci were composed of acute severe multifocal coagulative necrosis of hepatocytes and splenic pulp with infiltration of heterophils mixed with fibrin and dense colonies of gram-negative bacteria. Yersinia pseudotuberculosis was isolated from the lung, liver, spleen, heart, ovary, kidney, and trachea. The organism was susceptible to most antibiotics it was tested against, except erythromycin. Based on a retrospective study of necropsy submissions to CAHFS between 1990 and 2015, there were 77 avian case submissions of Y. pseudotuberculosis. There were 75/77 cases identified from a wide range of captive avian species from both zoo and private facilities and 2/77 cases from two backyard turkeys submitted from one premise. The largest number of cases originated from psittacine species (31/77). The lesions most commonly described were hepatitis (63/77), splenitis (49/77), pneumonia (30/77), nephritis (16/77), and enteritis (12/77). From 1990 to 2015, there was an average of three cases of avian pseudotuberculosis per year at CAHFS. Although there were no cases diagnosed in 1993 and 1994, in all other years, there were between one and eight cases of Y. pseudotuberculosis detected from avian diagnostic submissions.
