Milker's nodule is an occupational dermatovirose caused by Parapoxvirus, which is self-limited and, due to the lack of information of health professionals, may lead to underdiagnosis. We present two cases with exuberant manifestations and classic histopathologic findings. Case 1: Male, 19 years of age, milker, presented nodules and blisters on his palm for 15 days. Read More

Methicillin resistant Staphylococcus aureus (MRSA) is an emerging public health concern from dairy milk, and its diagnosis by phenotypic methodology is experiencing higher discrepancies. The present study was planned to estimate discrepancies in phenotypic identification of MRSA and MSSA (Methicillin sensitive Staphylococcus aureus) in relation to mecA, and prevalent risk factors from various localities. In-vitro oxacilline antibiotic disks were used for phenotypic identification of MRSA, whereas mecA gene was used as MRSA marker in Staph aureus by PCR. Read More

Viruses are considered intracellular obligates with a nucleic acid RNA or DNA. They have the ability to encode proteins involved in viral replication and production of the protective coat within the host cells but require host cell ribosomes and mitochondria for translation. The members of the families Herpesviridae, Poxviridae, Papovaviridae, and Picornaviridae are the most commonly known agents for cutaneous viral diseases, but other virus families, such as Adenoviridae, Togaviridae, Parvoviridae, Paramyxoviridae, Flaviviridae, and Hepadnaviridae, can also infect the skin.

Species members of the genus Parapoxvirus (PPV) within the family Poxviridae cause contagious pustular dermatitis in small ruminants (Orf virus, ORFV) and mostly mild localized inflammation in cattle (bovine papular stomatitis virus, BPSV and pseudocowpox virus, PCPV). All PPVs are known to be zoonotic, leading to circumscribed skin lesions in humans, historically known as milker's nodules. Human PPV isolates are often ill defined concerning their allocation to an animal origin. Read More

Background: Occupational exanthematic diseases represent an important cause of public health impact and economical losses. Among the viral exanthematic diseases, two caused by poxviruses are noteworthy: the bovine vaccinia (BV), caused by the Vaccinia virus (VACV); and the milker's nodule, in which the agent is the Pseudocowpox virus (PCPV). Both agents are zoonotic and have been associated with several cases of bovine infection. Read More

Background: Cutaneous infectious and inflammatory diseases may contain a significant number of CD30-positive cells, thus mimicking lymphomatoid papulosis (LyP) or anaplastic large cell lymphoma.
Methods: We reviewed our cases of non-neoplastic skin conditions with large, CD30-positive cells and searched the literature for similar cases.

Milker's nodules (pseudocowpox) are harmless skin lesions most commonly seen in persons whose occupation regularly brings them into close contact with cattle. They are caused by the paravaccinia virus, a member of the poxvirus family. Awareness of their clinical and histopathologic features is important, especially with today's heightened awareness of the threat of biologic warfare, to distinguish them from more worrisome entities such as tularemia and anthrax.

Two hundred years ago Edward Jenner inoculated James Phipps with vaccinia and 181 years later smallpox had disappeared from the surface of the earth as a result of generalized vaccination. Compared to the requirements of modern vaccinology, the procedures used by Jenner and his successors, were extremely primitive because of an almost total lack of knowledge in the field of microbiology and immunology. The active principle of smallpox vaccine is vaccinia virus, which in many respects, differs from that of natural cowpox; the term "cowpox" has been used for more than a century and a half to designate the vaccine; it appears itself to be a misnomer, because it is most probably by a virus of rodents, which only occasionally infects bovines or other species, especially cats.

The predominant skin problems in cattle-breeders are toxic and allergic eczemas, with cleansers, water, rubber, disinfectants and fodder being the most frequent provoking factors. The Danish register of occupational diseases yields information based on notifications during the years 1984-1992. Detailed data especially concerning dairy farms are not obtainable, but during the whole period 101 hand-skin diseases in farmers and farming assistants were notified, 12-23 annually in recent years.

Monoclonal antibodies were produced against orf virus-specified cell surface proteins in an attempt to develop reagents capable of differentiating between members of the Parapoxviridae. Two immunization protocols were used to induce an anti-orf response in BALB/c mice, one of which resulted in virus replication in the recipient. The monoclonal antibodies produced were tested for crossreactivity with bovine papular stomatitis virus (BPS) and milker's node virus (MNV) by indirect immunofluorescence assay (IFA) and immunoblotting.

In The Netherlands, human leptospirosis is mainly caused by the serovars icterohaemorrhagiae and copenhageni, both of which belong to the Icterohaemorrhagiae group and originate from rats, serovars hardjo from cattle and grippotyphosa from voles. In 1981-1987, 175 cases of leptospirosis were registered. In 17 of these cases the infection was acquired outside The Netherlands. Read More

Histopathologic, ultrastructural, and negative-staining studies indicated that nodular lesions on the flippers, head, and necks of recently weaned, captive grey seals (Halichoerus grypus) were similar to sealpox lesions reported from several other species of seals. Virions associated with the nodules were characteristic of the parapoxvirus subgroup of pox viruses. Two of the three persons handling the seals developed nodular lesions similar to "milker's nodules," the characteristic lesion in persons infected with parapoxvirus. Read More

The currently available methods for the serological and immunological diagnosis of human parapoxvirus infection (milker's nodule, farmyard pox) are demonstrated by the case of a man infected by contact with sheep carrying ecthyma contagiosum lesions. Compared to virus identification by electron microscopy, cell culture and animal experiments, identification of viral antigen in skin biopsies is equally sensitive during the first 2 weeks of the disease, whereas it is far more sensitive afterwards. The diagnosis of a parapoxvirus infection may be confirmed, even after skin lesions have healed, by assays for agglutinating, complement fixing, neutralizing and flocculating antibodies in patients' serum, the most sensitive method currently used being immunofluorescence and enzyme assays (ELISA).
