BACKGROUND: Species of Mycobacteriaceae cause serious zoonotic diseases in mammals, for example tuberculosis in humans, dogs, parrots, and elephants (caused by Mycobacterium tuberculosis) and in ruminants and humans (caused by M. bovis and M. caprae). Pulmonary diseases, lymphadenitis, skin diseases, and disseminated diseases can be caused by non-tuberculous mycobacteria (NTM). Diagnosis and differentiation among Mycobacterium species are currently done by culture isolation. The established diagnostic protocols comprise several steps that allow species identification...

Tuberculosis (TB) continues to represent an important public health challenge in the world and the USA, especially given its association with HIV infection and population migration. Cervical tuberculous lymphadenitis represents the most common extrapulmonary presentation of TB in the USA. Considerations for other causes of neck mass often contribute to delay in diagnosis. In this report, we describe the case of a 41-year-old man who presented with painful swelling of the neck and was diagnosed with tuberculous lymphadenitis, complicated by HIV therapy-associated immune reconstitution syndrome...

Caseous lymphadenitis (CLA) is an acute, pyogenic, and contagious disease of goat that imposes considerable economic losses for farmers, and it is caused by Corynebacterium pseudotuberculosis Herein, we introduce the genome sequencing of C. pseudotuberculosis strain KM01, isolated from an abscess of a Saanen goat from Kunming, China. The genome contains 2,198 genes, the total length of the genes was 2,337,666 bp, and the GC content was 52.18%. The number of tandem repeat sequences was 44, the total length of the tandem repeat sequences was 1,970 bp (0...

A 2-year-old Boer doe was presented with respiratory distress and severe inspiratory dyspnea. Cervical and thoracic radiographs revealed a marked retropharyngeal soft tissue mass effect, several mineralized pharyngeal and retropharyngeal structures, and a pulmonary mass. Computed tomography (CT) revealed a severely enlarged right medial retropharyngeal lymph node, which caused laryngeal compression, leading to upper airway obstruction. Multiple cervical and thoracic lymph nodes, and the pulmonary mass had an irregular layered/laminated pattern of mineralization...

Kawasaki disease is a systemic vasculitis that presents with stable vital signs. Although it is well known that Kawasaki disease can cause myocarditis, tachycardia and heart failure during the acute stage, Kawasaki disease shock syndrome (KDSS) has recently been described. It is characterized by hypotension, signs and symptoms of poor perfusion and a shock-like state. We report the case of a 7-year-old boy with KDSS who presented with persistent fever, conjunctival injection, laterocervical lymphadenitis, and echocardiography showing signs of myocardial dysfunction and shock...

Paraclostridium bifermentans (current nomenclature of Clostridium bifermentans since 2016) is a gram-positive, spore-forming anaerobic bacterium. Here, we describe two cases associated with this organism. The first, primarily a case of tubercular brain abscess where P. bifermentans was isolated as part of a polymicrobial flora, following a neurosurgical procedure for the same and the second, a case of cervical lymphadenitis from which it was isolated as the sole causative agent. There are only a few reported cases of P...

Enterobius vermicularis (EV) is a pinworm which commonly resides in the lumen of the intestinal tract and lays eggs on the perianal skin. However, rarely the worm can infest various other sites in the body and cases with infestation of such ectopic sites have been reported in literature. Rare cases of mesenteric lymph node involvement have also been reported. We report a case in a young male who presented with signs and symptoms of acute appendicitis. During surgery, enlarged mesenteric lymph nodes were identified...

No Typhoid Salmonella infection is one of the most common and widely spread foodborne diseases worldwide. Although most cases are limited to the gastrointestinal tract, extraintestinal involvement is not uncommon. However, adenitis as an isolated manifestation, is an unusual form of the disease. We report a case of Salmonella no Typhoid cervical lymphadenitis in a 67-year-old female with a recent diagnosis of diabetes mellitus, who was treated with surgery and ciprofloxacin.

In the 19th century it was widely believed that both tuberculosis and cervical lymph node swelling, known as scrophula, affected individuals predisposed to an inherited "diathetic constitution". In 1882 Robert Koch proved that human tuberculosis and scrophulous lesions were caused by the bacillus Mycobacterium tuberculosis. In the early twentieth century it was stated that Mycobacterium bovis, the bacillus of cattle tuberculosis, could also cause cervical lymphoadenitis in humans, especially in children, by the intake of milk from sick cows...

Introduction Cervical tuberculous lymphadenitis is a low-volume condition in the UK with a potential for delayed diagnosis. This study describes typical demographic and clinical features of patients diagnosed with cervical tuberculous lymphadenitis in a UK population. The utility of cytological, histological and microbiological investigations is reviewed with comparison between fine-needle aspiration and open biopsy. This information can facilitate recognition of new cases and guide initial management. Methods Patients diagnosed with cervical tuberculous lymphadenitis between January 2009 and December 2013 at two district general hospitals were identified from local infectious disease databases...

Haptoglobin (Hp) and Serum Amyloid A (SAA) are a group of blood proteins whose concentrations in animals can be influenced by infection, inflammation, surgical trauma or stress. Corynebacterium pseudotuberculosis is the causative agent of caseous lymphadenitis (CLA), and Mycolic acid is a virulent factor extracted from C. pseudotuberculosis. There is a dearth of sufficient evidence on the clinical implication of MAs on the responses of Hp and SAA in goats. Therefore, this study was conducted to evaluate the potential effects of Mycolic acid (MAs) and C...

The pathogenic bacteria of Corynebacterium pseudotuberculosis caused a chronic contagious infectious disease of the caseous lymphadenitis or pseudotuberculosis. Globally, isolates obtained from different injuries that affect sheep and goats, have been identified by fully or partially gene sequencing. However, in Mexico there is no complete study to identify by molecular and phylogenetic techniques the circulating isolates as well as its virulence factors. Therefore, in the present study we reported the identification of 57 isolates of C...

Yersinia enterocolitica is a zoonotic enteropathogenic bacterium that can cause acute gastroenteritis and mesenteric lymphadenitis. Although Y. enterocolitica is common in animals, food, and the environment, the reservoirs and transmission routes of this pathogen are still not fully understood. The aim of our study was to determine the prevalence of Y. enterocolitica in seafood in Germany, because only limited data are available on that topic. Seafood samples were purchased from retail shops in Berlin, Germany and examined for the presence of Y...

In late 2011, a variant pseudorabies virus (vPRV) emerged in Bartha-K61-vaccinated pig herds, resulting in high morbidity and mortality of piglets in China. Since 2013, the autopsy lesions, histological examinations, virus isolation, phylogenetic analysis and selection pressure analysis of the gE gene of vPRV were recorded for 395 clinical cases, and 5,033 pig serum samples were detected by PRV gE-coated enzyme-linked immunosorbent assay. The major clinical symptoms were abortion in pregnant sows, fatal neurological signs in piglets and respiratory disease in growing pigs...

We investigated the prevalence of Mycobacterium marinum lymphadenitis and describe 4 children with the disease. The database of the microbiology laboratory of a tertiary pediatric medical center was searched for all cases of nontuberculous mycobacterial lymphadenitis from 1996 to 2016. M. marinum lymphadenitis was defined as isolation of the pathogen from a lymph node or from a skin lesion with an enlarged regional lymph node. M. marinum was isolated from lymph nodes in 2 of 167 patients with nontuberculous mycobacterial lymphadenitis and from skin lesions in 2 children with skin lesions and regional reactive lymphadenitis, yielding a 2...
